I’ve used K3B just recently to RIP an Audio CD with music to MP3. K3b has done a great job ripping the tracks, the only problem was By default k3b RIPs songs in OGG Vorbis (.ogg) and not mp3. I personally prefer OGG Vorbis as it is a free freedom respecting audio format, however the problem was the .ogg-s cannot be read on many of the audio players and it could be a problem reading the RIPped oggs on Windows. I’ve done the RIP not for myself but for a Belarusian gfriend of mine and she is completely computer illiterate and if I pass her the songs in .OGG, there is no chance she succed in listening the oggs. I’ve seen later k3b has an option to choose to convert directly to MP3 Using linux mp3 lame library this however is time consuming and I have to wait another 10 minutes or so for the songs to be ripped to shorten the time I decided to directly convert the existing .ogg files to .mp3 on my (Debian Linux). There are probably many ways to convert .ogg to mp3 on linux and likely many GUI frontends (like SoundConverter) to use in graphic env.
I however am a console freak so I preferred doing it from terminal. I’ve done quick research on the net and figured out the good old ffmpeg is capable of converting .oggs to .mp3s. To convert all mp3s just ripped in the separate directory I had to run ffmpeg in a tiny bash loop.
A short bash shell script 1 liner combined with ffmpeg does it, e.g.;
for f in *.ogg; do ffmpeg -i "$f" "`basename "$f" .ogg`.mp3"; done.....
The loop example is in bash so in order to make the code work on FreeBSD it is necessery it is run in a bash shell and not in BSDs so common csh or tcsh.
Some time ago on one of the Database MySQL servers, I've configured replication as it was required to test somethings. Eventually it turned out replication will be not used (for some reason) it was too slow and not fitting our company needs hence we needed to disable it.
It seemed logical to me that, simply removing any replication related directives from my.cnf and a restart of the SQL server will be enough to turn replication off on the Debian Linux host. Therefore I proceeded removed all replication configs from /etc/my/my.cnf and issued MySQL restart i. e.:
sql-server:~# /etc/init.d/mysql restart
....
This however didn't turned off replication,as I thought and in phpmyadminweb frontend interface, replication was still appearing to be active in the replication tab.
Something was still making the SQL server still act as an Replication Slave Host, so after a bit of pondering and trying to remember, the exact steps I took to make the replication work on the host I remembered that actually I issued:
mysql> START SLAVE;
Onwards I run:
mysql> SHOW SLAVE STATUS;
....
and found in the database the server was still running in Slave Replication mode
Hence to turn off the db host run as a Slave, I had to issue in mysql cli:
I've been given a HUAWEI Mobile Broadband E173 USB 3g model. The USB modem contains a flash USB Storage segment storing a little install program dedicated to make the modem work fine on Microsoft Windows XP / Vista / 7 and probably other M$ OSes. I'm a long time DebianGNU / Linux user and as a free software enthusiast I ofcourse wanted to be able to use Vivacom's 3G USB Modem on my Linux powered notebook.
Thanksfully as I've red on Vivacom's website the modem supports Linux OS
For those unaware in Bulgaria there are currently 3 major GSM network providers providing 3G internet this are;;;
VIVACOM – The ex Government ran national company BTC (Bulgarian Telecommunication Company)
M-Tel – The first GSM network provider that entered Bulgaria around year 1995
GLOBUL – The 3rd and last GSM mobile and net provider entered last and not so much used by Bulgarians today
Until today I had no experience in running any 3G modems on Linux, neither I had used the 3 networks 3G internet to determine which one is best, however I've been given for temporal use a VIVACOM 3G internet modem today so I proceeded to try installing it on my Debian host.
My Linux system is a bit strangely configured as I use wicd network connection manager -( wicd-gtk ) to manage wireless and LAN connections instead of the standard installed GNOME network manager – available through package ( network-manager-gnome ).
The reason I use wicd is not that it is so much better than GNOME network manger but rather for historical reasons because few years past I had impression it works better in connecting me to wireless networks. Another reason why I choosed wicd back then was the nice looking stats …
I tried plugging in the Vivacom USB 3G modem stick and checked in wicd to see if I can see a possibility to connect to the mobile opeartor 3G network but unfortunately nothing appeared.
Though the 3G adsl modem was unavailable straing in wicd, checking about it in the list of attached USB devices I could see it detected, e.g.:
noah:~# lsusb |grep -i huawei
Bus 001 Device 007: ID 12d1:1c05 Huawei Technologies Co., Ltd.
This was at least a good sign pointing me to the thoughts that the modem is probably gonna work.
I did a quick Google search to see if other people succeded running the device on a Linux host and came across a few blog posts in Bulgarian explaining a "success story" on Ubuntu Linux through using a tweakened shell script – sakis3g. For more on how the script works and script download check out Sakis3g
Here is a quote from sakis3g's website describing the script:
It automagically setups your USB or Bluetooth™ modem, and may even detect operator settings.
You should try it when anything else fails!
Sakis3g has different versions designed for for plenty of spacific hware architectures i.e. for (i386, amd64, armv4t, armv5t).
There is also a version of the script which by the way contains a combination of bash shell scripting instruction and some binary exec data.
To run sakis3g on my laptop I did:
1. Download sakis3g
My notebook architecture is 64 bit so I download and used the amd64 version of the script;;;
hipo@noah:~$ mkdir sakis3g
hipo@noah:~$ cd sakis3g
hipo@noah:~/sakis3g$ wget http://www.sakis3g.org/versions/latest/amd64/sakis3g.gz
I've made also a mirror of sakis3g i386, 64 bit and all architecture the mirrors just in case it disappears in future. The mirror versions of sakis3g are here:
The script is then ready to run by either clicking twice on it or (as I prefer for debugging reasons to run it in terminal):
hipo@noah:~$ ./sakis3g
Something that I have wondered a bit was the dialog where I had to fill in some data of some variable APN abbreviation for – (Access Point Name)
The APN host for VIVACOM mobile internet is;;; APN: internet.vivacom.bg
I've used the Windows configuration progrma to gather also the following data that I thought might be important for configuring the 3G adsl modem on the Linux host;;;
Auth: *99#
User: VIVACOM
pass: VIVACOM
Here are all the configuration screenshots I've taken from sakis3g and all the data that I filled in.
Next the following tiny window appeared on screen:
Well that's all folks, now sakis3g succesfully connected to the I_net via an (PPP) VPN connection tunnel here is data from ifconfig command showing the succesful 3G connection to VIVACOM;;;
The internet via the 3G connection is not blazing fast but good enough to check your mail or read some webpages. VIVACOM currently has different (traffic limited packages) for their 3G internet, I'm not sure which package exactly is the 3G USB stick modem but probably the "quick" internet connection that is now would slow down once the traffic limit is reached …
Hope this post helps someone to configure 3G internet on VIVACOM in Debian and Ubuntu Linux. Though I've tested sakis3g on Debian it should work with no hassles on any other GNU Linux distribution that has bash installed.
As a person interested in history and antrophology. Just recently on my last trip to Romania as I travelled a very interesting question poped up in my mind – How it happened that RoadSigns we use on every street highway and practically everywhere on the road came to be. Interestingly now with the standartization of road signs often the most popular road signs are used as a basis for development on other popular prohibit or allowance signs, we read on airports public institutions, pubs and mostly everywhere.
So in short I did a short research on Road Sign History, just to find out once again that the ancients, were wiser than we think. The first road signs probably came to existence with the existence of humanity, however officially, there was no standartization of using signs to point on road locations travellers before it was introudced in the Roman Empire. In Rome a pillars on the roads were placed to point to major road arteries leading to Rome and various important empire city centers.
During the middle ages, milestones pillars were no longer used, but for practical reasons wooden markers placed across european cities instructed tradesman and travellers to major city important centers and were used to show a general road direction leading to nearby city.
The wooden signs practice had been in use until the first modern roadsigns erected on a wide scale designed for riders of 'high' and ordinary bicycles in the late 1870 and 1880s. The modern road signs as we know it today however emerged as a result of the first International Road Congress meeting that occured in Rome in 1908.
On the meeting a four standard pictures were selected to note the basic for road signs further development. The need for the meeting was the large increase of roads across european artery cities. The road signs developed on the meeting were bump, curve, intersection and railroad crossings. The invention and adoption of cars and the boom of the car producing industry quickened the need for international road sign standard. The intensive work on international road signs that took place between 1926 and 1949 eventually led to the development of the European road sign system as we know it. The signs were quicky spread to America and in 1960, the road signs become universal in America and almost everywhere all around the developed and developing world.
As of today 2012 it can be said road signs exist all around the civilized world.Though most of road signs are identical across all countries around the world today still some road symbols varies from country to country. I remember seeing some very unique road signs during my travelling through Serbia, 2 years ago.
I've personally always hated super markets from the very early days I entered one. Here in Bulgaria we've been somehow partly lucky not to have supermarket due to the different philosophy of the communistic regime in which we lived until 1991. The philosophy of then governing communist back then was to distribute food in local middle size or small stores owned by the government. The food has to be approved by governmental body and heavily checked if it matches the governmental set standards. The variety of food we were offered in the stores was very little. Most of the small stores (which were owned by the government) only contained basic products like;;;
bread, youghurt, milk, meat, butter, lemonade, beer and few more,
This was done probably intentionally and was a result probably of our long years Orthodox Christian faith which (has saved us and preserved over the centuries). Orthodox Christianity has always teached for simplicity. Even though the communist party rejected the faith and even did severe persecution against the Bulgarian Orthodox Church. The people on the top elite who were planning the communism had been a descent of an orthodox christian raised up living and therefore the philosophy of simplicity was inherited (even genetically) so the way the COM party behaved based on its leaders and the governing decisions about the nations belonging to communism (Russia, (Yugoslavia) – Serbia Koso , Bulgaria, Greece, Egypt etc.) were in a material expression in conjunction with the Christian tradition of simplicity (i say material because Orthodox Christian Church even visiting back then in the countries was usually prohibited and the Com. party did their best to ruin up the believe in Christ in people).
In communism the local suburb grocery stores, were the only "points" of distribution of food. Since buying and owning a car took at least few years of waiting and big money for it. Not more than 10 to 20% of families owned car and owning a car was considered to be granted mostly to people belonging to the then governing communistic elite or the Communist Party.
The public transportation was encouraged because according to communism so called "geometry" which was a main drive for how the systems in communistic countries should work it was estimated public transportation is cheaper and more environmental friendly than if a car is given to anyone, also public transportation (trains, bus-es) etc. did a good thing in the aim of the party to exersice higher control and surveilance over the population.
Because of that existence of big super-market was scarce and the culture to go and buy from a shop with your own family car was not existing.
The equivalent of nowdays mall shops (big retail stores) was usually located on the city center and the size of this shop was much smaller and the variety of products one can find there was only few. Hence the customer didn't have so much options to choose between, neither had to spend too much of time on choosing, the com party wanted the people to work more and buy less, so spending time in stores was not encouraged.
With the entrance of democracy and the moving up of large super-market food and good retails shops like Metro was among the first ones which entered the "freed" market. It was really a bizarre experience for us the ex U.S.S.R belonging people to enter such a large sized stores and to face such a big variety of choice.
Before that in communism we never saw such stores even on the TV, since the TV was governed by communistic party and only information which was useful for the establishment and protection of the regime was projected on the only available National TV channel.
Sorry to distract a bit from the major topic of this post, but I thought this is necessery to explain before continuing because it is important to understand that unintentinonally the communist gave us an advantage to have a different view on things than Western free world, a view which is in many things contrary and more correct (in terms of hard logic) than to Western Europe.
My first encounter with a super-market was only about 8 or 10 years ago and I believe many people who lived in the province of Bulgaria and other ex-communist countries did for a first time experience super-markets approximate 10y. ago. Though all looked so nice inside the shop and the shop emploees were so nice I always felt something very cold dead inside this big stores. Ptonsnlu my intuition (spirit) if you want has always pointed me out that there is something very wrong with this super markets.
With the increase of products on the market for us people who lived up to our 8 to 12 years (young age) in communism it was a great shock, since we were raised in a society based on some communist false ideology and suddenly the markets were opened and the products variety to choose between become extremely high.
All previously said to be good and true in communism time was said to be anti-freedom and many people did their best to destroy as much as possible mostly everything somehow connected with previous communistic time.
My homeland Bulgaria as a result of this become a very hard to live place and we were forced to adapt in fast paces and learn things on how we have to live like democrats for a very little short of time.
One severe "damage" most of the growing people in Bulgaria in communism had was the hardness and inability to make choices.
For many people between the age of 25 to 35 it is very hard to make choices even for small things.
This was a direct consequence of a long years (45 years) of communist propaganda, and few generations who lived in a non-freedom respecting regime which conditioned and prepared a specific plan and place for every individual living in the country.
Seeing communism as the ultimate evil and manipulation to make us dependent we didn't know that in the free democratic world the manipulation and conditioning in society was heavy too.
"The Programming" of western society through institutions, stores and order in society was a fact and in a sense the only difference between the Democratic world and communistic world was one of the worlds seemed to have a larger frame in which the individual can work and live, whether the communistic regime seem to be more restrictive.
One main thing used to condition people choices and buying behavior and make them over-consume to make the democratic economy constantly growth was big super-markets. Though they were privately owned and not like in communist country, the only drive behind each shop was PROFIT, PROFIT and agian PROFIT.
Higher profits would mean higher consumptions, higher consumptions means higher production and more work places opened as well as more expenses for working individuals would mean bigger necessity to work more and earn more, because though the sallaries incomes were high in the free world. The individual necessities there were even increasing too.
Since the about 1950s 1960s the super-markets started entering the "free" democrat countries world. As a result the small shops which were prior a main food and beverage distribution source started closing, because they couldn't be a concurrence to the big "brothers" super-markets which were able to buy higher quantities of goods in lesser price and therefore sell many of the goods in much lower prices than the little grocery stores.
The result with the years was a huge shift in people buying behavior from local groce and open markets to buy everything from the big super-markets. The big store chains had to be in a fight for customers all the time, so businesses involved started customer wars and tried their best to "steal" customers from each other. In this financial wars a main thing that most super-market chains and malls did was constant optimization of efficiency of both buying and reselling to the end customer. This is a 3 step business process actually.
1;;; They buy from the commodity producer 2;;; They prepare the food for the store (packaging, cleaning up whatever) 3;;; They put it in a certain way in the store and organize the store in a way to always sell more and more
As a result a huge number of tricks were employed by each and every super-market aiming to deceive the customer to ever buy more
The deception of the client in store is very tricky and smart organized so it cannot really be called a lie but its rather a tricky smartness.
Since the super-markets entered in my country too and the tiny grocery stores are mostly closing unable to compete with the large super-market 'money making machines'. Even I am sometimes forced to buy stuff from super markets. Since here in Bulgaria the culture of purchasing from super-markets is not so strong yet. In order to be able to consume the little grocery stores. Many large super-markets started investing in making the little groceries their retail shops with their brand or (sometimes a new make up brand).
By doing so the little grocery stores loose their authoritarity and independance and become dependant on the big super-market on the type of products they will sell, this obviously means this strategy of the big super-market in the long run will lead the little grocery stores we still have to ruin up. This is obvious because if the small grocery stores start selling the exact same products (brands) of the big super-markets, there will be nothing left to make the little grocery unique. Neither the variety of products choice inside or pricing will be any different from super-market. This will mean the tiny grocer will be no different from the big super-markets in terms of product and prices and therefore. The clients which now are loyal to small grocery stores like me will then have not such big motivation to buy from small super-markets, since everything inside is somehow similar (not to say) the same as with big supermarket the only difference would be the lesser variety which is obviously a good reason why the customer would definitely prefer to buy from the large supermarket …
On the videos you're about to see below, they explain some of the probably thousands of tricks nowdays existing the super-market chains employs to trick us to exponentiolly consume their goods.
Old Tricks of the SuperMarket Trade
As you can see the video is presenting a reality of the tricks which was used in the 1960 and now technology and knowledge in the field has largely increased and since they there are surely many new trick 'developments' which are working for the masses of customers daily.
There is even a whole science centered on buying behaviour already existent called buyology!
Here is a short introduction to buyology to give you an idea what its purpose is:
Short introduction video on buyology – The Science of buying part 1 of 2
Short introduction video on buyology – The Science of buying part 2 of 2
Seeing all this is very precious information, since being informed one can escape the bad "tricks and traps" pawn in the markets.
All the information about the communistic regime and the 'shopping system' there was mentioned priorly because I wanted to explain a bit of the difference of then and now to point you to my opinion that the Western buying model and expectation to sell more based on the tricks are probably not working very well here in the ex-communistic countries, especially with the older generations and the one like me which somehow grow a small part of their youth in communism.
The reason is we have a different 'social programming' than westerners. Also the different spirituality (The orthodox Christian faith) plays another role. Also there is a difference in the type of buying behaviour. In Bulgaria there is no culture to buy once or twice per week. People have culture to buy daily, though this is starting to change slowly these days.
The topic is actually very huge and I'm sure what I'm saying is just the 'tip of the iceberg'. As I'm a firm opponent of big industries and large business I'm firmly against the buying from big stores any goods. The reason is that simply by doing so one makes the already RICH people even more RICHER. By increasing the richness of a certain small group of people daily, we as society are un-consciously somehow involuntarily letting them increase the financial control that is already there in some degree to the society.
As democracy's main drive is money this means that by helping the large business-es marge and become even BIGGER, we're doing something against ourselves and our interests as society.
I don't think that any ordinary citizen in the free world want to live in a fully controlled one World State (one world country), similar to the ex-communism I lived through, so I think people concerned about our freedoms should oppose the big businesses according to the society level they're in. Even if we're not in position to change things with money, we as society are in a position to change ourselves and our understanding of world, our desires and our behaviour. If we change our value system in a way, where money are not a top priority and the highest value the outcome will be positive in both spiritual terms and overall world state.
The modern day however wants us to falsely believe that we're divided, helpless and money dependent. This is a big delusion which we're constanty repeated. Just like with the super-market this big super-market company owners were able to convince us through time that super-market is better than the grocery stores, because of the less money spending advantage. Even if in the past there were possibility to spend less via supermarket nowdays spending less by using the supermarket instead of the small groce-store is a BIG LIE. Even if one spends less in super-market on certain products, the amount of related products he is cheated* to buy in store highly exceed the simply money one would spend on even higher priced products in the small groce.
The outcome results from the super-market is also a big waste, as I lived in the west I've seen most of the households are buying more than they need, spending more than they need, cooking more food and more frequently than necessery and throughing large portions of food in the garbage (e.g. a huge amount of food waster).
If it was possible that people were aware they are buying all this non-sense food because of deception, they would have bought less, the super-markets would bought less and distribute less and the food (waster) remaining could be distributed to poor-er countries to help the starving kids and suffering people in Africa.
Helping the suffering and starving, we would have helped each other as it is a nowdays well known that even on molecular level the whole world is connected, therefore helping our poorer brothers and sisters is actually helping ourselves ***
I've been thinking about our modern day progression and what our "progressed" society looks like in reality.
We think we have progressed, we have built machines that serves us well (computers). We plan for a bright painless easy future day by day. This bright "perfect" society future is nothing more than the dream of communism in its complete form.
But in what sense we have actually progressed ?? Everyone who really sees what happens around us notice the big changes we experience. On the surface it looks like our life has become much easier with all this technology surrounding us. The number of computers which is said to help us to leap towards this bright future increases day by day. With this however increases the need to support technology. Suddenly it happens that the old believe that computers are just a tool to make our life earier becomes a modern day slavery. Most of the developed or under development countries people are nowdays almost full time spending in front of the computer screen on the internet. We put our lifes in the mercy of man-created computers and it has become impossible that we live or exist independetly without them.
Computers are everywhere around us starting from the work Desk, at hand with a notebook, ipad, mobile phones, cars, airplanes. There is rarely to see any technology we use which works with not some kind of primitive or advanced computer embedded ,,,
In the rise of computers as we know it computer was just a tool to help us along with the other overall thought and inventions development. Now from just being a tool to help us progress Computers become the common ground on which almost everything in life works.
I'm sure many people who started learning computer technology 15-20 years ago (like me) never imagined computers will integrate so heavily in our daily activities as they eventually did.
We use computers for the sake of planning which in "spiritual language" is predicting the future or prophecise what is about to come in the short future. In reality what we do mostly even not realizingly is to try to predict and modify the future through technology.
This concept is also existing in most sci-fi movies, made in last 60 years. Mobile phones revolution give the humanity a tool through which telepathy we've seen in so many SCI-FI is reality. The mobile phone is just a platform through which (phone calls) or better said voice telepathy has become possible. In that manner of thoughts it is obvious that Video phone calls is a voice + visual telepathy. The Skype revolution and Video and voice conferences is brought was just until recently seen on the sci-fi movies where spaceship crews communicated with other spaceship crews by using a Visual conferences like skype.
It is really hard to believe that for just few years now everyone can speak with ease with everyone else on the planet in the same way just like we've seen in the movies as some foreign abstract concept!
Now suddenly most people on earth are equipped with technology with gives them the power to do everything but it is my firm believe people are not ready to wisely use this power. Therefore instead of using this higher technology wisely technology is used mostly senseless and the more technological advancement grows and becomes more accessible to the masses the more the tendency to use the technology for shit grows.
I'm sure people who have a good knowledge on programming and how computer works are already seriously aware of this enormous problem.
Another severe problem with the raise of technology is the language slang it introduces. This tech-slang is adopted quickly all around the society and suddenly as a result the human language as we know it is seriously substituted by a vague tech words mambo-jambo words. Actually the adoption of tech buzz words in modern day society language makes a great harm for the reason communication between people becomes less descriptive and therefore harder.
In short the result of this tech slang language inside our national languages is inability for people to communicate properly. This tendency is well seen if you for example try to make a comparison between old and newer movies. The newer the movie the less meaningful it is. It is true newer ones has much more as a visual adds than the predecessor but when talking about consistency the newer films are missing this point seriously.
As newer generations are born and raised up with this newer movies and "advanced" TV and computers this people doesn't even have most of the time the opportunity to see older human taped knowledge.
Even for youngesters who have somehow a wise parents enough to teach them in a religious way or just have the "luck" to have parents with old world mindset it will be extremely hard if not impossible for this kids to understand the old knowledge, as most of their same age school / university fellows will only talk about the newer things.
Besides all this, computers as they grow needs more and more support "nurturing" so day by day more and more people has to be busy with managing and supporting tech stuff. Suddenly it is no longer clear if computers serve us or we serve them, this tendency is already somehow evident but not so clearly as it will be in the short 5 to 10 years.
Therefore we slowly but surely are moving to a society which might become "enslaved by technology". Why I say here enslaved, because if we spend our time on fixing computers and technology and working with one virtual reality (which is non-reality) in essence this means we no longer have a physical freedom in the sense it was God given.
There is no doubt computers at present appears to do us a big good, but if you think a bit strategically it is obvious this good has it's price. By adopting all this technology without questioning ourselves on how this will impact our human freedom, we build a computerized jail around us. At first this jail appears to be so wide that it seems it does not interfere with our freedom, but with the introduction of newer and newer computer technology this jail becomes narrower as to the point where it could threat our physical existence freedom.
For those who could argue my thoughs I will ask two simple questions to show you how dependent we've become on technology;;;
What was the last time you switched off your mobile for a week ?
What was the last time you didn't used computers and the internet for a week time ?
Obviously rarely we can find someone that will answer positively to this question or even the thought of switching off from this so globalized society by dropping off tech stuff for a week seems scary.
This constant connectiodness that we're day-by-day heavily exposed to is scary, because it steals little-by-little our natural freedom for seclusion / pravicy / solitude.
This freedoms, were essential and especially for Christian saints and many of the people in the Holy Bible if we read closely we will find out they have used this freedom in parts of their lives especially the seclusion to hear and understand God's will for their life.
Since technology is stealing us the freedom to seclude ourselves this means it steals our basic natural freedom to communicate with God and our natural self ,,,
The consequence of this separation from God and unification with "the world" surely will lead to spiritual blindness and lack of good foundation or higher life purpose, in other words lost path in life.
This is happening all along right in front our eyes now.
Maybe the worst thing of globalization is it doesn't unite people on a soul level but rather separates them. The unification that tech boom gives to people is in the "virtual reality" but this is not a real unification as it is unification in a media which is not real.
Yes Virtual Reality is not real, that's why it is called Virtual isn't it?
I've been thinking over all this problems more and more and I'm starting to come to conclusion that people who wish to keep their essential physical freedom need to GET OUT from this tech lie, we have lived in.
For this however more people need to first realize that;;;
1. TECHNOLOGY LEADS US NOWHERE!
2. People who want to live without technology need to organize in groups – (and get used to a natural living growing food, being near to a natural springing water, taking care for each other, living in a Christian commune like – like in the old days)
Actually if we read the old testament's story of Moses escaping the upcoming flood, I believe what is about to come to us as a consequence of this out of boundaries technologization is pretty much like the old testamental flood (this should happen sooner or later).
Moses was wise enough to make himself an Ark and prepare himself for the storm. Today most people are so busy that they don't see the storm coming. I'll be glad to hear from people who has the same thinking as me and want to organize in a groups and live an old humble way of life without technology.
I'm convinced people who have realized all this tech short future bad consequences on humanity, need to have a common communication media and share their knowledge on how we can find a way to live tech free in this age. I'm curious am I the only one with such thoughts or other get into this insight too. If you have come to conclusions I did please contact me in comments. Thank you.

Of course in order for remote talks to work properly the firewall (if such has to be modified to allow in.ntalkd chats. I've never used in.ntalkd and on most machines having in.ntald hanging around from inetd, could be a potential security hole so, for people not planning to initiate remote TALKs between Unix / Linux / BSD hosts on a network it is a good practice the ntalkd line seen above in inetd.conf to be commented out ::;
3.;;; Restart openbsd-inetd init script and talk is ready to use
noah:~# /etc/init.d/openbsd-inetd restart
* Restarting internet superserver inetd
Onwards to use talk between two users the syntax is same like on other BSD, as a matter of fact TALK – console / terminal interactive chat originally was developed for the 4.2BSD UNIX release ;; the Linux code is a port of this BSD talk and not rewrite from scratch.
Using talk between two logged in users on pts/1 (lets say user test) and tty1 (user logged as root) is done with:
On tty1 the user has to have enabled Talk sessions request, by default this behaviour in Debian and probably other Debian based Linuxes (Ubuntu) for instance is configured to have talks disabled, i,e ,,,
root@noah:~# mesg
is n
Enabling it on root console is done with:
root@noah:~# mesg y
Once enabled the root will be able to see the TALK service requests on tty1 otherwise, the user gets nothing. With enabled messaging the root user will get on his tty:
Message from TalkDaemon@his_machine...
talk: connection requested by your_name@your_machine.
talk: respond with: talk your_name@your_machine
So on the root console to reply back to talk chat request:
I have a bunch of old html files all encoded in the historically obsolete Windows-cp1251. Windows-CP1251 used to be common used 7 years ago and therefore still big portions of the web content in Bulgarian / Russian Cyrillic is still transferred to the end users in this encoding.
This was just before the "UTF-8 revolution", where massively people started using UTF-8,
Well it was clear the specific national country text encoding standards will quickly be moved by to UTF-8 – Universal Encoding format which abbreviation stands for (Unicode Transformation Format).
Though UTF-8 was clear to be "the future", many web developers mostly because of their incompetency or using an old sources of learning how to writen in HTML continued to use windows-cp1251 in HTMLs. I'm even convinced, there are still developers out there who are writting websites for Bulgarian / Russian / Macedonian customers using obsolete encodings …
The smarter developers of those accustomed to windows-cp1251, KOI-8R etc. etc., were using the meta tag to specify the type of charset of the web page content with:
Anyhow, still many devs even didn't placed the windows-cp1251 in the head of the HTML …
The result for the system administrator is always a mess – a lot of webpages that are showing like unreadable signs and tons of unhappy customers.
As always the system administrator is considered responsible, for the programmer mistakes . So instead of programmers fix their bad cooking, the admin has to fix it all!
One quick work around me as admin has applied to failing to display pages in Cyrillic using the Windows-cp1251 character encoding was to force windows-cp1251 as a default encoding for the whole virtualhost or Apache directory with Apache directives like:
Though this mostly would, work there are some occasions, where only a particular html files from all the content served by Apache is encoded in windows-cp1251, if most of the content is already written in UTF-8, this could be a big issues as you cannot just change the UTF-8 globally to windows-cp1251, just because few pages are written in archaic encoding….
Since most of the content is displayed to the client by Apache (as prior explained) just fine, only particular htmls lets's ay single.html, single2.html etc. etc. are displayed with some question marks or some non-human readable "hieroglyphs".
Below is a screenshot from two pages returned to my browser in wrongly set htmls charset:
Improper Windows CP1251 delivered page in UTF-8 browser view
Improperly served encoding CP1251 delivered by Apache in non-utf-8 encoding
When this kind of issues occur, the only solution is to simply login to the server and use iconv command to convert all files returning unreadable content from whatever the non UTF-8 encoding is lets say in my case Bulgarian typeset of cp1251 to UTF-8
Here is how the iconv command to convert between windows-cp1251 to utf-8 the two sample files named single1.html and single2.html
I always, make copies of the original cp1251 encoded files (as you see mv single1.html single1.html.bak), because if something goes wrong with convertion I can easily revert back.
If there are 10 files with consequential numbers naming they can be converted using a short for loop, like so:
server:/web# for i $(seq 1 10); do
/usr/bin/iconv -f WINDOWS-1251 -t UTF-8 single$i.html > single$i.html.utf8;mv single$i.html single$i.html.bak
mv single$i.html.utf8 single$i.html
done
Just as earlier mentioned if single1.html, single2.html … has in the html <head>:
You should open, each of the files in question and wipe out the line either by hand or use sed to wipe it in one loop if it has to be done for lets say 10 files named (single{1..10})
server:/web# for i in $(seq 1 10); do
sed '/<meta http-equiv="Content-Type" content="text\/html; charset=windows-1251>/d' single$i.txt > single$i.txt.new;
mv single$i.txt single$i.txt.bak;
mv single$i.txt.new single$i.txt
I don't know if someone has thought about this topic but in my view Facebook use in organizations has a negative influence on companies overall efficiency!
Think for a while, facebook's website is one of the largest Internet based "people stealing time machine" so to say. I mean most people use facebook for pretty much useless stuff on daily basis (doesn't they ??). The whole original idea of facebook was to be a lay off site for college people with a lot of time to spend on nothing.
Yes it is true some companies use facebook succesfully for their advertising purposes and sperading the awareness of a company brand or product name but it is also true that many companies administration jobs like secretaries, accountants even probably CEOs loose a great time in facebook useless games and picture viewing etcetera.
Even government administration job positioned people who have access to the internet access facebook often from their work place. Not to mention, the mobility of people nowdays doesn't even require facebook to be accessed from a desktop PC. Many people employeed within companies, who does not have to work in front of a computer screen has already modern mobile "smart phones" as the business people incorrectly call this mini computer devices which allows them to browse the NET including facebook.
Sadly Microsoft (.NET) programmers and many of the programmers on various system platforms developers, software beta testers and sys admins are starting to adopt this "facebook loose your time for nothing culture". Many of my friends actively use the Facebook, (probably) because they're feeling lonely in front of the computer screen and they want to have interaction with someone.
Anyways, the effect of this constant fb use and aline social networks is clear. If in the company the employeed personal has to do work on the computer or behind any Internet plugged device, a big time of the use of the device is being 'invested' in facebook to kill some time instead of investing the same time for innovation within the company or doing the assigned tasks in the best possible way
Even those who use facebook occasionally from their work place (by occasionally I mean when they don't have any work to do on the work place), they are constantly distracted (focus on work stealed) by the hanging opened browser window and respectively, when it comes to do some kind of work their work efficiency drops severely.
You might wonder how do I know that facebook opened browser tab would have bad interaction with the rest of the employee work. Well let me explain. Its a well known scientifically proven fact that the human mind is not designed to do simultaneously multiple tasks (we're not computers, though even computers doesn't work perfect when simultaneous tasks are at hand.).
Therefore using facebook in parallel with their daily job most people nowdays try to "multi task" their job and hence this reflects in poor work productivity per employee. The chain result cause of the worsened productivity per employee is therefore seen in the end of the fiscal quarter or fiscal year in bad productivity levels, bad or worsened quality of product and hence to poor financial fiscal results.
I've worked before some time for company whose CEO has realized that the use of certain Internet resources like facebook, gmail and yahoo mail – hurts the employee work productivity and therefore the executive directors asked me to filter out facebook, GMAIL and mail.yahoo as well as few other website which consumed a big portion of the employees time …
Well apparantly this CEO was smart and realized the harm this internet based resources done to his business. Nowdays however many company head executives did not realize the bad effect of the heavy use of public internet services on their work force and never ask the system administrator to filter out this "employees efficiency thefts".
I hope this article, will be eventually red by some middle or small sized company with deteriorating efficiency and this will motivate some companies to introduce an anti-facebook and gmail use policy to boost up the company performance.
As one can imagine, if you sum up all the harm all around the world to companies facebook imposed by simply exposing the employees to do facebooking and not their work, this definitely worsenes the even severe economic crisis raging around …
The topic of how facebook use destroyes many businesses is quite huge and actually probably I'm missing a lot of hardmful aspects to business that can be imposed by just a simple "innocent facebook use", so I will be glad to hear from people in comments, if someone at all benefits of facebook use in an company office (I seriously doubt there is even one).
Suppose you are a company that does big portion of their job behind a computer screen over the internet via a Software as a Service internet based service, suppose you have a project deadline you have to match. The project deadline is way more likely to be matched if you filter out facebook. Disabling access to facebook of employees and adding company policy to prohibit social network use and rules & regulations prohibiting time consuming internet spaces should produce good productivity results for company lightly. Though still the employees can find a way to access their out of the job favourite internet services it will be way harder.
If the employee work progress is monitored by installed cameras, there won't be much people to want to cheat and use Facebook, Gmail or any other service prohibited by the company internal codex
Though this are a draconian measures, my personal view is that its better for a company to have such a policy, instead of pay to their emloyees to browser facebook….
I'm not aware what is the situation within many of the companies nowdays and how many of them prohibit the fb, hyves, google plus and the other kind of "anti-social" networks.
But I truly hope more andmore organizations chairman / company management will comprehend the damages facebook makes to their business and will issue a new policy to prohibit the use of facebook and the other alike shitty services.
In the mean time for those running an organization routing its traffic through a GNU / Linux powered router and who'd like to prohibit the facebook use to increase the company employees efficiency use this few lines of bash code + iptables:
#!/bin/sh
# Simple iptables firewall rules to filter out www.facebook.com
# Leaving www.facebook.com open from your office will have impact on employees output
# Written by hip0
# 05.03.2012
get_fb_network=$(whois 69.63.190.18|grep CIDR|awk '{ print $2 }');
/sbin/iptables -A OUTPUT -p tcp -d ${get_fb_network} -j DROP
If the script logic is followed I guess facebook can be disabled on other company networks easily if the router is using CISCO, BSD etc.
I will be happy to hear if someone did a research on how much a company efficiency is increased whether in the company office facebook gets filtered out. My guess is that efficiency will increase at least with 30% as a result of prohibition of just facebook.
Please drop me a comment if you have an argument against or for my thesis.
I'm used to making picture screenshots in GNOME desktop environment. As I've said in my prior posts, I'm starting to return to my old habits of using console ttys for regular daily jobs in order to increase my work efficiency. In that manner of thoughts sometimes I need to take a screenshot of what I'm seeing in my physical (TTY consoles) to be able to later reuse this. I did some experimenting and this is how this article got born.
In this post, I will shortly explain how a picture of a command running in console or terminal in GNU / Linux can be made
Before proceeding to the core of the article, I will say few words on ttys as I believe they might be helpful someone.
The abbreviation of tty comes after TeleTYpewritter phrase and is dating back somewhere near the 1960s. The TTY was invented to help people with impaired eyesight or hearing to use a telephone like typing interface.
In Unix / Linux / BSD ttys are the physical consoles, where one logs in (typing in his user/password). There are physical ttys and virtual vtys in today *nixes. Today ttys, are used everywhere in a modern Unixes or Unix like operating system with or without graphical environments.
Various Linux distributions have different number of physical consoles (TTYs) (terminals connected to standard output) and this depends mostly on the distro major contributors, developers or surrounding OS community philosophy.
Most modern Linux distributions have at least 5 to 7 physical ttys. Some Linux distributions like Debian for instance as of time of writting this, had 7 active by default physical consoles. Adding 3 more ttys in Debian / Ubuntu Linux is done by adding the following lines in /etc/inittab:
On some Linux distributions like Fedora version 9 and newer ones, new ttys can no longer be added via /etc/inittab,as the RedHat guys changed it for some weird reason, but I guess this is too broad issue to discuss ….
In graphical environments ttys are called methaphorically "virtual". For instance in gnome-terminal or while connecting to a remote SSH server, a common tty naming would be /dev/pts/8 etc.
tty command in Linux and BSDs can be used to learn which tty, one is operating in.
Here is output from my tty command, issued on 3rd TTY (ALT+F3) on my notebook:
noah:~# tty
/dev/tty3
A tty cmd output from mlterm GUI terminal is like so:
hipo@noah:~$ tty/dev/pts/9
Now as mentioned few basic things on ttys I will proceed further to explain how I managed to:
a) Take screenshot of a plain text tty screen into .txt file format b) take a (picture) JPG / PNG screenshot of my Linux TTY consoles content
1. Take screenshot of plain text tty screen into a plain (ASCII) .txt file:
To take a screenshot of tty1, tty2 and tty3 text consoles in a txt plain text format, cat + a standard UNIX redirect is all necessery:
This will dump the text content of the console into the respective files, if however you try to dump an ncurses library like text interactive interfaces you will end up with a bunch of unreadable mess.
In order to read the produced text 'shots' onwards less command can be used …
noah:~# less /home/hipo/tty1_text_screenshot.txt
noah:~# less /home/hipo/tty2_text_screenshot.txt
noah:~# less /home/hipo/tty3_text_screenshot.txt
2. Take picture JPG / PNG snapshot of Linux TTY console content
To take a screenshot of my notebook tty consoles I had to first install a "third party program" snapscreenshot . There is no deb / rpm package available as of time of writting this post for the 4 major desktop linux distributions Ubuntu, Debian, Fedora and Slackware.
Hence to install snapscreenshot,I had to manually download the latest program tar ball source and compile e.g.:
noah:~# cd /usr/local/src
noah:/usr/local/src# wget -q http://bisqwit.iki.fi/src/arch/snapscreenshot-1.0.14.3.tar.bz2
noah:/usr/local/src# tar -jxvvvf snapscreenshot-1.0.14.3.tar.bz2
…
noah:/usr/local/src# cd snapscreenshot-1.0.14.3
noah:/usr/local/src/snapscreenshot-1.0.14# ./configure && make && make install
Configuring…
Fine. Done. make.
make: Nothing to be done for `all'.
if [ ! "/usr/local/bin" = "" ]; then mkdir –parents /usr/local/bin 2>/dev/null; mkdir /usr/local/bin 2>/dev/null; \
for s in snapscreenshot ""; do if [ ! "$s" = "" ]; then \
install -c -s -o bin -g bin -m 755 "$s" /usr/local/bin/"$s";fi;\
done; \
fi; \
if [ ! "/usr/local/man" = "" ]; then mkdir –parents /usr/local/man 2>/dev/null; mkdir /usr/local/man 2>/dev/null; \
for s in snapscreenshot.1 ""; do if [ ! "$s" = "" ]; then \
install -m 644 "$s" /usr/local/man/man"`echo "$s"|sed 's/.*\.//'`"/"$s";fi;\
done; \
fi
By default snapscreenshot command is made to take screenshot in a tga image format, this format is readable by most picture viewing programs available today, however it is not too common and not so standartized for the web as the JPEG and PNG.
Therefore to make the text console tty snapshot taken in PNG or JPEG one needs to use ImageMagick's convert tool. The convert example is also shown in snapscreenshot manual page Example section.
To take a .png image format screenshot of lets say Midnight Commander interactive console file manager running in console tty1, I used the command:
Here is a resized 480×320 pixels version of the original screenshot the command produces:
Storing a picture shot of the text (console) screen in JPEG (JPG) format is done analogously just the convert command output extension has to be changed to jpeg i.e.:
I've also written a tiny wrapper shell script, to facilitate myself picture picture taking as I didn't like to type each time I want to take a screenshot of a tty the above long line.
Here is the wrapper script I wrote:
#!/bin/sh
### Config
# .tga produced file name
output_f_name='console-screenshot.tga';
# gets current date
cur_date=$(date +%d_%m_%Y|sed -e 's/^ *//');
# png output f name
png_f_name="console-screenshot-$cur_date.png";
### END Config
snapscreenshot -c$arg1 -x1 > $output_f_name && convert $output_f_name $png_f_name;
echo "Output png screenshot from tty1 console produced in";
echo "$PWD/$png_f_name";
/bin/rm -f $output_f_name;
The script is quite simplistic to use, it takes just one argument which is the number of the tty you would like to screenshot.
To use my script download it in /usr/local/bin and set it executable flag:
