My long lasting study university dilemma is it really worth Investment to study in University? Don’t study – invest your money in something more meaningful

Thursday, December 13th, 2012

I'm trying to graduate for a really long time, so far. Let me in short perephrase my story, as I'm sure there are probably plenty of people out there who are into the same shitty situation as I.

I graduated school while being 17 years old (one year earlier than supposed), studied in a Mathematical oriented High School with majors Informatics and Mathematics with itensified English language studying. 

While turning 17 I had my regular fancy-dress carnival (ball) as we have it each year near the end of May and beginning of June in Bulgaria, in those joyful times plenty of High School graduates has their celebrations. I don't know how it is in other countries but in Bulgaria, graduates are often mislead and does not have clear idea what exactly they want to study, because schools do less to properly orientate the student on what kind of study stream field or what kind of sphere of life he would like to be employeed (maybe it was just my alumni) or the alumnis student generations that emerged just 10 years after Communism regime fall, maybe it is just my individual case. Or maybe it was like this everywhere? Anyways I graduated desiring only to study informatics for the only reason, Informatics was fashionable and it was thought the future of existence will be fulyl pre-dominated by informatics. Therefore in my school me and many classmates thought graduating in informatics is the best thing one can do. Computers back in the day was not so heavily spreaded (every person did not have a computer), so still computers were perceived by Bulgarian people with high dose of mysticism and interest. And those interested in computers were much more interested into learning something and much less consumer oriented society … but doesn't matter, I can write a lot of this but will stop here as this is not the ultimate goal of this article ….

Once graduating in PMG Ivan Vazoff – The High School where i graduated, I tried to apply for a student by following the standard student entrance exams for the study stream of Computers and Information Technologies as this was my primary field of interest back in the day. Back in the day the only way to enter for study stream of Computer Engineering was lay exam solving 4 mathematical complex problems, mathametics. I'm a very bad mathematician and bad in counting, since my childhood I guess I had some bad teachers which didn't spend enough time explaining, I was lazy or just I don't have the talent to be good in mathematics, so following the exams in few mainly Technical Universities in few Bulgarian cities produced no good results. Because of my bad exam marks (my best one was 3 out of 6, where 2 is negative and 6 is positive – yeah the standard education system in Bulgaria is from 2 (poor) to 6 (excellent), I was not accepted in any of the universities to study informatics. You can understand my high disappointment, I was so keen to study informatics really! but the stupid system never allowed me to do so! Hoping I will be able to transfer to another study stream I signed in Varna TU (Technical University) in a study stream called "Machine Building and Instruments Construction". I was received in student with a very low mark of just 3 out of 6, there was practice back in the day that the students with worst marks entered into the Machine Building and Instruments Construction or Automation specialties. I was a total user, as the name of the specialty sounded not so bad and I hoped the specialty should be closely related to Informatics, I had hope. Spending just the first semester in the University I realized this specialty – as it was taught back then has almost nothing to do with Computing; besides that it had plenty of Engineer Drawings. As a graduate from a High School where accent was Mathematics, I never did even one Engineer Drawing! So it was a complete, mess I tried hard to learn  it but it was not possible, even though I tried my best I couldn't properly Draw. After all I never had the habit and even the basic knowledge on How Engineer Drawing is done. It was sad and stressful times, besides that I had to follow two University Higher Mathematics (Chapter 1 and 2) in 1st semester and University Technical Mathematics (Chapter pt. 3 and 4). First semester I couldn't pass Mathematics exam  1 and 2. Because of the reason the teacher was mostly terrible in explaning and also the level of mathematics required to know was very high; for me it was even harder as I never ever had good understanding or knowledge in mathematics. I failed the exams I hardly passed 2 out of 4 exams, I had troubles with few subjects certification (in those university studyign students, had to be certified by the teacher to go to the exam – if you don't attend the lectures you don't get certification and you can't go for the exam). It was a mess. After the end of 1st year I realized, I cannot in any way make it, to move myself to study in some study specialty that has to do more with Computer Science, so I stopped studying. 

During the summer I visited some private Mathematics lessons and tried my best to apply again to study for informatics this time for another University (The Economic University of  Varna). Though my hard attempts to learn a set of model mathematical tasks to solve, on the exam in June I only could achieve again a low mark 3.80 out 6. I needed at least 5 in order to be approved to enter the pre-selected number of students which would study Informatics. Here a note to make here is most of the students who studied informatics did not hold even basic understanding in computers or did not even been keen on computers ….

So in practice again I couldn't enter the study stream I wanted so I was accepted in a study stream called Commodity Knowledge (which consisted of a lot of Chemistry doing chemical analysis of products testing, if they're suitable for putting in store things like this). As a bad mathematician my knowledge in Chemistry was also not good, not to mention I had a very short life memory, so sciences with a lot of formulas (and a lot to remember) are so unsuitable for me …. Anyways I was trying to be very diligent in this Commodity Knowledge study, and I could even pass all my  exams in the first year with not so bad overall marks of around 4.30 out of 6.

I should say I spoke with administration and in first semester I was told it is possible to transfer in Computer Technology specialty if I have relatively good marks, they blutantly lied to me, since after talking with them in the end of the first year I was told the two study systems of Commodity Knowledge and Computer Technology has difference, so the only option is to start again from year 1!!!!! I was mad and disappointed, but decided to just study Stock Knowledge for the reason I already started it with hard intention this time I will graduate. Somewhere in the middle of year 2 in University, I was totally pissed off the studies, besides that at home there were plenty of family problems, so I was devastated. My mother and father was hardly urging me to find a job immediately because they cannot (or will not)  financially support me anymore. After some search on the Internet I was referred by a friend (from my school years who lived in Sofia) about a company called Design.BG which is looking for a Linux system administrator. I already had plenty of experience with Linux and Operating System as this was my hobby and most of my free time was invested in learning Linux, advancing my knowledge in Operating Systems, learning Computer Programming etc. etc. I went to the interview and was approved !!! Hooray I had job but I was paid a very funny money 250 lv (125 EUR) – of course I was just starting in this job but come on 125 EURO for a system administator responsible for 6 servers – 125 EURO per month was meakly ridiculous….

I worked in this company Design.BG for overall of 7 years. After 4.5 year of working and a working sallary of 450 lv I just quit, they were plainly using me as a Robot is used, ridiculous and stupid. I had some good times in the company made some friends, advanced my knowledge this is true. But after all after 4.5 years working in an office I had neither savings, neither achieved something and living on rent – working month by month for my rent and monthly food (very similar to people in Africa). A friend of mine who lived in Dobrich and also was very disappointed from his started Education and quit, told me he will be signing to study in a (comparatively new College) located in Dobrich (Holland-Dutch College ICA – International College Albena). I went to this college and signed up for the studies, usually the students were asked to study 1 preparation year, because they need to advance their English (all subjects were taught in English). As I had a relatively normal English I went to an interview in the College and to one Intelligence test exam and I was approved to start studying immediately without following preparation year 1.

The days while being in the College was relatively good, as somehow I managed to pass two years there in the specialty of International Business and Management (IBMS). After year 2 it appeared there was not enough students in my student group, so there couldn't be year 3. We were only 6 students in IBMS and 3 of them had plans to transfer to continue their studies in another Business School (Arnhem, Business School) in the Netherlands. I was again in a difficult situation, from one side I wanted very  much to go and see how living is abroad from Bulgaria, since I never went out of Bulgaria, but from other side I didn't have enough money to do it, so I had to ask for financial support from my parents, I went to banks asking for Student Credit but since my parents had little of earnings, the banks were not willful to provide me a student credit of 10000 lv. (5000 EUR) which even will not be enough for graduating; however I was dreaming to go and study abroad so I make plans that I can gradute with maybe only 7500 EURO. It was just after I realized how my plans are wrong I needed much more to graduate. The good news I had job as I continuously worked for Design.BG (as remote system administrator). so I was earning 650 euro – a money I hoped will be enough to support my studies, as well administrating few other Servers for Winner Ltd (a smal.l company started and owned by my best friend from my youth years). After a lot of "disputes" with my family

I was able to convince them to help me with money to go to the Netherlands.. I went here in Holland, thinking it is all like a bed of roses. I thought here I will be able to find a good job make a good earning. But guess what it was nothng like this. I realized it is pretty hard to find a good job in Netherlands, besides that Bulgaria was not in Shengen so we Bulgarians could only work if we have a special issued work permit document – the Employer however issues this only in case if there is no suitable Dutch person for the job + issuing this document is often seen as problematic by employeer. Thus as a consequence most of Bulgarians even if they find job have to "work in the dark" in the grey economy without being officially employed with a contract or paying a social security or taxes. Such kind of jobs are mainly provided by Turkish or Kurdish and often even those who get job are underpaind or the employeer lies him with money, and you have nothing to do since officially you have no employment contract ….

I signed up for itjobboard.nl a website providing some resources for people who are involved in IT searching for job but nothing decent poped up.

In Arnhem Business School I signed up under Human Resources and Quality Management specialty – this was one of the biggest mistakes in my life (from current perspective) – was always interested in social studies, so I thought HR will be good. However it might be, but the people I meet in face of teachers in University of Arnhem and Nijmegen (ABS) in HRQM was a hell. They were even worser than the ones in Bulgaria (and I always thought in Bulgaria people are narrow minded), here in Holland they were even more narrow minded. They were preaching what they believe, trying to impose themselves on the student constantly trying to manipulate you. Trying all kind of techniques which are against the normal people code of ethics. Experimenting hardly with experimental Psychology, Hypnosis, NLP – what can I say just a bunch of totally crazy ungodly people. Education, here in the Netherlands was a hell.

Teachers didn't care for the student even more than they don't care in Bulgaria. Teachers failed to identify brilliant minded students, but was forcing ahead only students, which somehow was pretending to be smart. Besides that my colleagues in study group's IQ and experience was far from the even minimal for a serious study and scientific thinking (of course this are just my 5cents), I had troubles with money. What made it even more of a nightmare was the fact in Netherlands people though being smiling and ethical was not too much believing in God and there was no regular Orthodox Church services. There is just one Orthodox Church here in Arnhem and they had 1 Church service per month  …. I have studied plenty of Bullshit subjects in Arnhem Business School. The only so-so reasonable was Counceling and International Labour Law. What made my studying situation even more hellish was the fact. The subjects taught here in Arnhem Business School are not identical as content to the ones I was taught over the 2 years I studied in Holland-Bulgarian College (International College Albena). The style of teaching was also very different. Here the student is left on his own to spend his nerves on shit issues, most of which are caused by the badly architectured university system and the unwillingness of teachers to be helpful to students. From my overall experienced in Arnhem Business School in HRQM. I urge you don't sign and Study for HRQM. This might be the biggest mistake you will make. The nerves,. the lost times and the brainwashing you're about to get with a shit content is not worthy the time and the price of tuition fee of 1672 euro per year. I've studied 1 year here in Arnhem Business School somehow managing it and I was totally devastated for the reason I spend 1 year with Teacheres who constantly practice brainwashing techniques doing lecture over the students. Besides that all system in the specialty is centered around a false Philosophy of Brainwashing. The teachers claim, they do all to help the student – they even have a study-buddy system but in practice it is totally opposite. Teachers do opposite to what they speak, acting often totally devilish. It is not a place for ethical people with high morale. Besides that I was amazed about the stupidity of information system in Arnhem Business School, all is built very complex and hard for the student; Whole information system is based on Proprietary Microsoft software. Even the wireless access to the Internet from the University is not officially supported for Free Opearting systems like GNU / Linux or FreeBSD. This  is a good indicator on how narrow minded the whole university is …. well it is the same old story with almost all education I have faced in my life. You pay and you get "shit" for your money, if hopefully you graduate you're not prepared so it is just like spending a lot of money on almost nothing.

The investments one does for his whole studying is another story, very often you spend about lets say 10000 to 15000 EURO for studies and the ROI could come someday or maybe not. With the harsh economic crisis and the reduce of management positions and increase of technology, the likeness of not getting a job or getting a shit underpaid job with or without Higher Education is quite high. Even the knowledge you get in moment of graduating is already out date due to the high dynamics of economics throughout the world and globalization. 

I have planned to complete Arnhem Business School for just 2 years of time, but the teachers and subjects make me stumble, so it is already almost 4 years and I still haven't graduated. Where I'm a position where I had to take two accounting exams. Here the subjects in Arnhem Business School has all fuzzy names like ILLW / (ACF1, ACF5Z0) / HRA. What makes situation even worser is this code names are changed with time. As I didn't studied for an year and half I had issues re-signing for studying. Even after I was said I can continue my studies from the moment where I stopped, there was plenty of issues that might be because the fact they changed the HRQM study content and even the specialty name HRQM was changed to IBS. Now I'm in a situation, where I need to pass two accounting exams they were used to be called under the fuzzy names ACF5 and ACF7 (Accounting and Finance). Again I'm a big troubles because I'm so bad with numbers and the university is so unflexible so they don't give you any alternative option to following the two accounting Exams. After all there are plenty of HRQM Managers out there which have not a good idea about numbers, besides that being an HR does not require you to have the knowledge of a professional accountant. But according to the exams I have to follow I have to study from a book which seems like for professional accountants ….. Passing the 2 accountings would have not been such an issue but the big problem is this two accountings ACF5 and ACF7 are a continuous ones from a previous ACF1,2,3,4 and I never studied ACF1,2,3,4 in Bulgaria but instead studied a different kind of accounting, which besides that was poorly taught by the teacher who didn't speak a good English and the Exam content has nothing as prior said nothing to do with the Accountings in ABS. Even though I spoke with the teachers and explained my situation numerous times, noone wants to take my big issue seriously and now I'm suffering trying to learn for this exams, but with my knowledge it seems hardly possible to pass the exams. Besides that which is mostly ridiculous is just for passing this 2 exams the university wants to charge me to pay them for a whole Study Year enrollment (via StudieLink – an online based system through which the student Sign ups for studying in Holland Universities – in Holland there is a commission of people who approves if one will study or not). It could be my bad luck, maybe my temper which is freeedom loving or the complexity of modern life, but I didn't like it.

Even if I graduate after some time find the enormous sum of about 1650 EURO, I don't know if I will be able to find job after that. Just to give you an idea about the approximate sallary in Bulgaria is about (150 to 200 EUR) MAX. Where only the IT jobs and some managers take like 1000 EUR of sallary. It is ridiculously high, what is even more ridiculous I forgot to mention is even though in year 2011 (January – June) I didn't studied or attended even one lecture the university required me to pay the Semester Tuition fee of 836 EUR (the second part of the normal study year). My explanation that I couldn't go to school because of health issues and financial reasons was not taken in consideration at all. I come to the conclusion that all studying are just made to drain your money and nobody really cares of you. And even at the end who cares what kind of diploma you have you only find Job in 80% of cases only if you have a person to refer you , recommend you  and place you in company. It is just sad how stupid and fragile the education system is in the EU.

Moreover this stupid European Union helps me nothing, they just say they help the countries but what I see happening in Bulgaria and across most of the European Countries speaks the opposite. 

Drawing GANTT Charts and Project Management on Linux, (Microsoft Project substitute for Unix)

Tuesday, October 12th, 2010

I'm studying Project Management, right now. In that spirit of thoughts I and a couple of other guys are building a Project Plan.
As it Project Plan it's necessary to put a GANTT Chart in it to show visually the project timeline (the phases), the duration and the inter-relation between the different tasks which leads the project to an actual completion.

After a bit of thorough research online on available software to deal with project management and particularly, ones that are capable to build a GANTT charts on Linux / BSD.

I've come with the following list of software capable to be a substitute for the Microsoft Project software.
Redmine GANTT Chart

GANTT chart Redmine

1. Gantt Project
GANTTProject chart GANTTProject Chart

2. Gnome Planner
Planner GANTT Gnome Chart Planner GANTT Chone Chart

3. Task Juggler Project Manager with GANTT Capability for (KDE)
Task Juggler

4. JxProject – This software is not free, though it can be considered almost free
Take a look also at:
5. Trac , though it doesn't really support GANTT charts it's a lovely software to be used for PM.
Trac Project Management

Another option you have is to try out:
6. PHProjekt

Update 20.09.2016 – PHPProject Old download link is no longer active

It is this link http://www.phprojekt.com/, but the page doesn’t seem to be active any more. I thought you might want to update.

If you are looking for an alternative please check out http://wiht.link/PHProjekt-PM, it may make a suitable replacement.

Kind Regards,
Tom Wilcox


That piece of softwre really looks promising, especially if we consider that it's web based and how much essential is today to have an anline tools for doing the ordinary desktop jobs.

You can even check an online demo of the PHPProjekt software here

If you're a type of KDE user you definitely has to try out Kplato

As I've tested the software the software is easy to be used, however it still is missing some essential parts that Microsoft Project includes so it's not 100% substitute.
Also it's not able to open Microsoft Project (MPP) files, neither able to save the charts in the .mpp format.

Moving ahead I've came across DotProject DotProject Gantt Chart
DottProject Gantt Chart

I haven't took the time to test it myself but however, as I go through the software website the project looked quite good.
Lastly you can take a look at: 7. PStricks as a mean of project management, however I think it doesn't support GANTT chart building.

Linux: how to show all users crontab – List all cronjobs

Thursday, May 22nd, 2014

linux-unix-list-all-crontab-users-and-scripts
I'm doing another server services decomissioning and part of decomissioning plan is: Removing application and all related scripts from related machines (FTP, RSYNC, …). In project documentation I found a list with Cron enabled shell scripts:

#Cron tab excerpt:
1,11,21,31,41,51 * * * */webservices/tools/scripts/rsync_portal_sync.sh

that has to be deleted, however there was nowhere mentioned under what kind of credentials (with what kind of user) are the cron scripts running? Hence I had to look up all users that has cronjobs and find inside each user's cronjobs whether respective script is set to run. Herein I will explain shortly how I did that.

Cronjobs by default has few locations from where cronjobs are setupped depending on their run time schedule. First place I checked for the scripts is

/etc/crontabs # cat /etc/crontabs SHELL=/bin/sh
PATH=/usr/bin:/usr/sbin:/sbin:/bin:/usr/lib/news/bin
MAILTO=root
#
# check scripts in cron.hourly, cron.daily, cron.weekly, and cron.monthly
#
-*/15 * * * * root test -x /usr/lib/cron/run-crons && /usr/lib/cron/run-crons >/dev/null 2>&1
59 * * * * root rm -f /var/spool/cron/lastrun/cron.hourly
14 4 * * * root rm -f /var/spool/cron/lastrun/cron.daily
29 4 * * 6 root rm -f /var/spool/cron/lastrun/cron.weekly
44 4 1 * * root rm -f /var/spool/cron/lastrun/cron.monthly

I was not really user via what user is shell script run, therefore I looked first if someone doesn't set the script to run via crontab's standard locations for Daily, Hourly,Weekly and Monthly cronjobs:
 

a) Daily set cron jobs are in:

/etc/cron.daily/

b) Hourly set cron jobs:

/etc/cron.hourly

c) Weekly cron jobs are in:

/etc/cron.weekly/

d) Monthly cron jobs:

/etc/cron.monthly

There is also a location read by crontab for all Software (package distribution) specific cronjobs – all run under root user privileges.:

e) Software specific script cron jobs are in:

/etc/cron.d/  
As the system has about 327 users in /etc/passwd, checking each user's cronjob manually with:

# crontab -u UserName -l

was too much time consuming thus it is a good practice to list

/var/spool/cron/*

directory and to see which users has cron jobs defined

 

# ls -al /var/spool/cron/*
-rw——- 1 root root 11 2007-07-09 17:08 /var/spool/cron/deny

/var/spool/cron/lastrun:
total 0
drwxr-xr-x 2 root root 80 2014-05-22 11:15 .
drwx—— 4 root root 120 2008-02-25 15:45 ..
-rw-r–r– 1 root root 0 2014-05-22 04:15 cron.daily

/var/spool/cron/tabs:
total 8
drwx—— 2 root root 72 2014-04-03 03:43 .
drwx—— 4 root root 120 2008-02-25 15:45 ..
-rw——- 1 root root 4901 2014-04-03 03:43 root
 


/var/spool/cron – is crond (/usr/bin/cron/)'s spool directory.

# ls -al /var/spool/cron/tabs/ total 8
drwx------ 2 root root 72 2014-04-03 03:43 .
drwx------ 4 root root 120 2008-02-25 15:45 ..
-rw------- 1 root root 4901 2014-04-03 03:43 root

Above output shows only root superuser has defined crons.

Alternative way to check all user crontabs is via quick Linux one liner shell script show all user cron jobs

for i in $(cat /etc/passwd | sed -e "s#:# #g" | awk '{ print $1 }'); do
echo "user $i --- crontab ---";
crontab -u $i -l 2>&1 >/dev/null;
echo '----------';
done|less

Note that above short script has to run with root user. Enjoy 🙂

Saint Thecla and Saint Isidore of Seville – A Patron Saint of programmers, information freaks and IT nerds

Friday, January 18th, 2013

I learned a very curious fact. We have two Christian saints St. Thekla and St. Isidore of Seville which are protectors of Computing and people involved with computational sciences programming and IT related jobs. 
The two saints both lived before the Great Church Schism thus the saints are celebrated and venerated nowadays in Roman Catholic Church and Eastern Orthodox Churches all around the Christian world.

The Holy living of Saint Thecla – The ProtoMartyr (The first Christian woman martyr)

St Thekla saint protecting all IT people and people who work with computers

The reason why Saint Thecla is considered a protector of all people who heavily work with computers and possibly hackers 🙂 is her name, Tecla means "Key" (a keyboard one) in Spanish.
Besides that everyone knows Keys (Passwords) and codes – a sort of keys as well as keys in programming arrays are widely used in Informatics and are essential part of computer basic Software.

Saint Thecla's living is mostly interesting, below is a short story of her earthly live as recognized in Orthodox Christian tradition;

Saint Thecla is considered a direct pupil of Saint Apostle Paul as she turned to be preacher of Christianity after speaking saint Apostle Paul. She lived in 30 A.D. until 1-st century after Christ. St. Thecla was virgin and decided not to mary even though she had fiancee in moment where she heard the Gospel of Christ.

She was miraculously saved from being burned at a stake by the onset of a storm, and traveled with Paul to Pisiduan Antioch. There a nobleman named Alexander desired Thecla and attempted to take her by force. Thecla fought him off, assaulting him in the process, and was put on trial for assaulting a nobleman. She was sentenced to be eaten by wild beasts (a common punishment for Christians in 1st century). Again saved by a series of miracles when the female beasts protected her against her male aggressors.

She sought out St. Paul and his companions, including St. Barnabas, who were hiding in a cave near the city. She spread the gospel of Christ with them in Antioch, and throughout her life performed many miraculous feats and suffered many tortures to give glory to God. Having retired to a desolate region of Isaurian Seleucia with the blessing of St. Paul, Thekla continued to preach God's word and heal st. Paul's spiritual children.

She lived to venerable old age of 90. Even in this old age envious pagan sorcerors come with the intention to defile the holy virgin. .  A large rock split open when St. Thekla called on Christ the Savior to help her, and the rock covered her, and she offered up her soul to the Lord.

St. Thecla is highly venerated by Nuns an interesting fact is during tonsure of nuns in the Orthodox Church, her prayerful intercession for the tonsured nun is invoked.
 

Saint Thekla Protomartyr first christian woman martyr and protector of computer related professions and nerds

The Kontaktion and Troparion as sung in the Church on her day feast in Orthodox Church – September 24 is;
 

Hymns Troparion (Tone 4) [2] You were enlightened by the words of Paul, O Bride of God, Thekla, And your faith was confirmed by Peter, O Chosen One of God. You became the first sufferer and martyr among women, By entering into the flames as into a place of gladness. For when you accepted the Cross of Christ, The demonic powers were frightened away. O all-praised One, intercede before Christ God that our souls may be saved. Kontakion (Tone 8) O glorious Thekla, virginity was your splendor, The crown of martyrdom your adornment and the faith you trust! You turned a burning fire into refreshing dew, And with your prayers appeased pagan fury, O First Woman Martyr!

Saint Tecla is very important woman saint, there is a whole monastery dedicated to her – Saint Tecla Monastery in Ma'loula

 

Saint Isidore of Seville – St Isidore  Archbishop of Seville – An important Christian Saint writer from 6th century

St Isidore of Seville patron saint of System administrators, database programmers and IT experts



St Isidore lived (circa 560-636), he served as Archbishop of Seville. Apart from his great holiness in modern terms, he can be defined as "information freak" and even in modern terms Nerd 🙂 Even in his living he was recognized as miracle worker. St. Seville just like me and most IT people had a hobby of knowing as much as possible, he collected texts and write books on scientific or quasi-scientific facts and theories on subjects from Scripture, Church order, materials, and jurisprudence and medicine to achritecture, agriculture, botany,  food, drink furniture,war, navigation ! etc. etc. 🙂
His books are among the first attempts to create universal catalog of available information in the World. His writtings are a sort of ancient Wikipedia. Even to this age his books provide us with many information and instruction on Church dogmatics and life as understood from a Christian view.

Saint Isidore's most notable work is Etymologiae – which is among the first encyclopedias worldwide – a huge compilation of 448 chapters in 20 volumes.
Contrary to many critics of Christian faith claiming that the Holy Fathers or the Church teach the earth is square shaped and one can reach the end of the world in St. Isidore's work, it is clearly explained that the earth has a circle like form.
 

Diagrammatic world map 12th century as described by st Isidore of Seville the world is round!!!!

Saint Isidore was contemporary to Saint Maxim the Confessor and one of the last ancient Christian Philopsophers, and last of the Great Western Church Holy fathers
According to some sources, saint Isidore is said to be the most learned man of his age. His works played key role on development of Middle-ages educational life. It is curious fact that in year 2000, the Vatican proclaimed Saint Isidore as patron saint of the Internet.
In Orthodox Church, we're not the authority of the Vatican Pope, so for us Orthodox Saint Isidore is not patron saint of Internet, however his contribution for increase of worldly knowledge as we know it today is un-questinable. His Holy relics are currently held in Roman Catholic Cathedral in Murcia (Spain), so any Orthodox Christian who is in deep involvement IT who travels to their or happen to live their might drop by to venerate the saint.
 

saint Isidore of Seville creator of first Christian and knowledge encyclopedia

St. Isidore's episcopate was during a time of disintegration and transition as the ancient institutions and knowledge of the Roman Empire were disappearing. During these times, he set himself to the task of joining into a homogeneous nation the many peoples who made up the Gothic kingdom. To accomplish this task he used all the resources of religion and education available to him. He presided over the Second Council of Seville in November 619, leading to the setting forth of the nature of Christ in the Acts of the council, as he pushed for the eradication of Arianism.

saint Isidore of Seville Christian enlightener of Spain evident Christian 6th century writer - important Archibishop played key role for unification of the Goths nations

A  list of all his works, most of which are unfortunately present on the Internet only in Latin are:

  • Historia de regibus Gothorum, Vandalorum et Suevorum (a history of the Gothic, Vandal and Suebi kings)
  • Chronica Majora (a universal history)

How to print simple text pages on Linux in console with old LPR parallel port attached printer

Tuesday, February 7th, 2012

LPT parallel port pinout diagram with explanations

Many younger people, might not know lpr command, historically it was heavily used for printing in the early GNU / Linux days.
lpr ships the text to be printed to the printer which is physically attached on LPT (Line Print Terminal) parallel port . Those who lived the DOS era surely know in those "ancient" days, everyone who wanted to print has to use the LPT parallel port

Present time, everyone knows there is almost no modern printer that is attached to the PC via LPT port but rather the USB port is used for communication between the printer the computer.
Nevertheless The USB printers on Linux are managed by CUPS, the lpr command is still functional shipping the text to be printed via CUPS (cups-lpd daemon).
Before cups-lpd was introduced the service managing the print jobs was lpd
Hence lpr is still functional.

To print a plain text file of one page with lpr on Linux:

linux:~# cat text-file-to-print.txt | lpr

For multiple printers to switch between multiple printers there is the PRINTER shell variable:

linux:~# export PRINTER=printer-Name-and-Type

To print a really long text file (a book in TXT) the pr command comes handy. As you can read in the cmd manual pr converts text files for printing

Lets say you would like to have a 60 lines of text per printed page, the cmd to issue is:

linux:~# pr -l60 text-file-to-print.txt | lrp

All queued printing jobs can be reviewed with the lpq, if you have a printer attached try:

linux:~# lpq
lp is ready and printing
Rank Owner Job Files Total Size
active hipo 1 text-file-to-print.txt 62045 bytes

Since some years it is pretty rare for people to use lpq, since most of the parallel printing is managed by CUPS server, what most people use nowdays to check the printer queue is lpstat : e.g.

linux:~# lpstat
...

Printing status and all things related to queued jobs for printing gets logged in /var/log/lpr.log

There is even more simplistic way to print directly to the printer (if the printer is attached via a LPT port) through the kernel /dev/lp, for example:

linux:~# cat text-file-to-print.txt >> /dev/lp

For more than one printer attached the naming of /dev/lp, might probably be /dev/lp0, /dev/lp1 etc.
The lprm command also exists in case if you would like to cancel a printjob in the queue. Lets say I want to cancel a job in the queue with Job ID 5:

linux:~# lrpm 5
...

To cancel a current running job in the middle the /usr/bin/cancel command exists.

An interesting historic fact is that nowdays opening lpr, lpq or any of the other tools for simple text mode printing one sees on top of the page Apple Inc.

Lets clear this up CUPS (Common Unix Printing System) (open source) printing platform is not owned by Apple, since it is licensed under GPL2 and LGPL. The reason why the Apple Inc. shows up in man pages is because in year 2007, the founder of CUPS printing server Michael Sweet hired him to work for Apple Inc. "purchasing" the CUPS source. However as we know they did not really purchased the code, because the code was already belonging to the community (licensed under GPL2). Apple however as a marketing trick used the fact that Sweet worked for them and as probably as a matter of marketing asked him to place the Apple Inc. in the copyright source and manual areas. Obviously this is not true, since Apple Inc. does not hold copyright for CUPS as CUPS can be copied by anyone (its open source) 😉

Most of the people will never print using this commands, since printing is now, ages ahead, anyways for simple people (like me), who just need to print a text with no special fonts or graphics text printing is just great.

Text printing is also a good learning experience for Linux novices and is good to be known just as a piece of UNIX history.
