Today I’ve received wonderful news! I have been accepted to the System And Network Engineering Master at the University of Amsterdam! Starting from the end of August I’ll be relocating to Amsterdam for one year of full geek experience (hopefully!). I can not thank enough my girlfriend on being such a great support and motivator.Without her nothing could have happened. Also my teachers (esp prof. Rughinis and prof. Tapus) at the Faculty of Automatic Control and Computer Science at University POLITEHNICA of Bucharest have been great mentors and supporters of my admission.
This could be a good time to add this blog to your RSS reader as starting from September I’ll be posting regularly on both geek related stuff and the lifestyle of an international student in the Netherlands.
Meseriasii de la /n (aia care dadeau stickere moca) au un produs tare fain. Ii zice powershell server si jucaria iti transforma masina windows din o statie unde poti face chestii doar via GUI in una bucata statie accesibila remote via ssh. SSH vine de la Secure shell. Ei bine daca secure e clar ce ne da, shell aici e inlocuit cu PowerShell. In felul asta se poate controla o masina windows doar cu putty! (yes Powershel rocks! )
Putina paranoia nu strica, ba char face foarte mult bine. Dupa ce am vazut niste loguri cam suspecte mi-am adus aminte ca a arde gazul in nestire cu zilele cautand pe internet absolut nimic are unele avantaje.
Pe scurt: china are cel mai mare numar de utilizatori din lume (sau daca nu are o sa aiba foarte curand). Asta inseamna ca sunt foarte multi utilizatori “emergenti” care pot fi usor de fraierit in a isi transforma pc-ul in sursa de spam. Avand in vedere barierele de comunicare dintre cele doua civilizatii sansele ca cineva sa imi acceseze coltul meu de internet sunt exteeeem de mici. La fel ca mine gandesc si altii mai luminati.
O lista cu reguli de firewall (IPTABLES sau Cisco ACL) pentru toate netblockurile din China sau Coreea. Nu suna foarte politically correct dar e gradina mea si o ingrijesc asa cum pot.
In cinstea noului meu tricou pe care scrie “<geek>” azi ne distram putin cu un RFC de 1 Aprile.
The truths described in this memo result from extensive study over an
extended period of time by many people, some of whom did not intend
to contribute to this work. The editor merely has collected these
truths, and would like to thank the networking community for
originally illuminating these truths.
1. Introduction
This Request for Comments (RFC) provides information about the
fundamental truths underlying all networking. These truths apply to
networking in general, and are not limited to TCP/IP, the Internet,
or any other subset of the networking community.
2. The Fundamental Truths
(1) It Has To Work.
(2) No matter how hard you push and no matter what the priority,
you can't increase the speed of light.
(2a) (corollary). No matter how hard you try, you can't make a
baby in much less than 9 months. Trying to speed this up
*might* make it slower, but it won't make it happen any
quicker.
(3) With sufficient thrust, pigs fly just fine. However, this is
not necessarily a good idea. It is hard to be sure where they
are going to land, and it could be dangerous sitting under them
as they fly overhead.
(4) Some things in life can never be fully appreciated nor
understood unless experienced firsthand. Some things in
networking can never be fully understood by someone who neither
builds commercial networking equipment nor runs an operational
network.
(5) It is always possible to aglutenate multiple separate problems
into a single complex interdependent solution. In most cases
this is a bad idea.
(6) It is easier to move a problem around (for example, by moving
the problem to a different part of the overall network
architecture) than it is to solve it.
(6a) (corollary). It is always possible to add another level of
indirection.
(7) It is always something
(7a) (corollary). Good, Fast, Cheap: Pick any two (you can't
have all three).
(8) It is more complicated than you think.
(9) For all resources, whatever it is, you need more.
(9a) (corollary) Every networking problem always takes longer to
solve than it seems like it should.
(10) One size never fits all.
(11) Every old idea will be proposed again with a different name and
a different presentation, regardless of whether it works.
(11a) (corollary). See rule 6a.
(12) In protocol design, perfection has been reached not when there
is nothing left to add, but when there is nothing left to take
away.
In a minimum-phase system there is an inextricable link between frequency response, phase response and transient response, as they are all merely transforms of one another. This combined with minimalization of open-loop errors in output amplifiers and correct compensation for non-linear passive crossover network loading can lead to a significant decrease in system resolution lost. However, this all means jack when you listen to Pink Floyd.
This year i’ve been a very bad boy but I still want that special someone back. Besides that I want Gears of War2, a YJM guitar, world peace and less bugs in my code. Also I want my backups to last forever.
Ocazional ma uit la ce vizitatori mai am. Daca data trecuta era vorba despre cineva cu lynx acum e asta:
Mozilla/4.0 (compatible; MSIE 4.01; Digital AlphaServer 1000A 4/233; Windows NT; Powered By 64-Bit Alpha Processor)
Primul DEC Alpha l-am vazut cand lucram la Ministerul Economiei si era cam cat un frigider arctic mai mic. Rula OpenVMS si Oracle 7. Avea legat de el o cutie cu vreo 24 de hdd-uri scsi ficare de cam 3gb. La vremea lui costase foarte mult (poate chiar prea mult) iar cand am ajuns eu era piesa de muzeu. Tin minte ca amicul cmihai a fost in extaz cand i s-a dat mana libera sa il manevreze.
Saptamana trecuta Radu mi-a zis ca mai e unul prin Poli, in laboratorul Compaq-Oracle (ce acum e cam parasit si e loc de intalnire pentru niste organizatii studentesti sau centru de testare Pearson VUE).
Sistemul de operare de pe el era remarcabil, OpenVMS fiind un fel de bunic al Windows NT. O buna bucata din echipa de la OpenVMS s-a mutat la MSFT si au pus umarul la cea vea sa fie NT 4.0. Anumite concepte din VMS se regasesc in sistemele de operare actuale Windows. Legenda urbana zice ca Windows NT se numeste asa pentru ca daca iei VMS si incremetenzi pozitia fiecarei litere cu 1 obtii WNT. Nu stiu cat de mult adevar e aici dar o poanta similara e in Odiseea spatiala 2001 unde computerul malefic se numeste HAL; iterat cu 1 obtinem IBM.
