Ce este o telecomandă universală? (Universal Remote Control)
În zilele noastre mai toate aparatele sunt prevăzute cu telecomandă(Remote Control). Aceasta înseamnă multă bătaie de cap, atât datorită numărului mare de telecomenzi, învățatul funcțiilor acestora, găsirea unui înlocuitor în caz de defect și nu în ultimul rând multe baterii, mult prea multe baterii!!!
Așadar, ce este o telecomandă universală? (Universal Remote Control)
În principiu o telecomandă folosește impulsuri de lumină infraroșie pentru a comunica cu aparatul controlat la distanță (de unde și denumirea în engleză de remote control). Constructiv și ca principiu de funcționare, telecomenzile nu diferă foarte mult, ceea ce diferă este doar asocierea de impulsuri ce reprezină o comandă specifică pentru un anumit aparat. O telecomandă universală este capabilă, întocmai ca un cameleon, să preia funcțiile celor mai populare telecomenzi. Prin urmare, o telecomandă universală poate comanda în același timp un CD Player, un televizor, o combină audio, un receiver de satelit, un DVD Player sau un Video Recorder.
Există un buton specific pentru fiecare aparat, iar alegerea tipului de aparat se face prin introducerea unui cod specific ce se găsește în manualul telecomenzii.
Mai concret. Cum se programează o telecomandă universală?
Am televizor Philips si Video Recorder Samsung si o telecomandă universală Sony. Mă uit pe eticheta din spate a fiecăruia pentru a vedea Marca si Modelul și le caut în tabelul cu coduri oferit de producătorul telecomenzii. Urmez instrucțiunile de utilizare specificate în manualul telecomenzii și voila, am o singura telecomandă pentru mai multe aparate. Mai mult decât atât, pentru o mai mare ”ușurință în utilizare” și pentru a nu o pierde, au apărut telecomenzile ”jumbo” de dimensiuni foarte mari.

Dirty Operating System
Computer stupidities – part 1 Operating Systems
I open here a new series of topics regarding “Computer stupidities”. Many of them comes from http://www.rinkworks.com/stupid/ or from other sources.
… collection of stories and anecdotes about clueless computer users. It’s a baffling phenomenon that in today’s society an individual, who might in other circumstances be considered smart and wise, can sit down in front of a computer screen and instantly lose every last shred of common sense he ever possessed. Complicate this phenomenon with a case of “computerphobia,” and you end up with tech support personnel having phone conversations that are funny in retrospect but seem like perfectly valid motives for wild machine gun shooting sprees at the time. You will read stories in this file that will convince you that among the human race are human-shaped artichokes futilely attempting to break the highly regarded social convention that vegetables should not operate electronic equipment. And yet, amidst the vast, surging quantities of stupidity are perfectly excusable technological mishaps — but that are amusing nonetheless. After all, even the best of us engages in a little brainless folly every once in a while.
http://www.rinkworks.com/stupid/ Rink Works
Let’s begin, with part 1 Operating Systems:
* Customer: “My machine won’t do anything.”
* Tech Support: “What’s on the screen right now?”
* Customer: “It’s frozen, it’s showing my Windows desktop.”
* Tech Support: “Try hitting Ctrl-Alt-Delete, tell me what happens.”
* Customer: (taptaptap) “Nothing.”
* Tech Support: “Did you hit all of them at once?”
* Customer: “Umm…just a second.” (taptaptap) “I did that time. Nothing happened.”
* Tech Support: “Try it again.”
* Customer: (taptaptap) “No, it’s just sitting there.”
* Tech Support: “Move the mouse around. What happens?”
* Customer: “Nothing, the arrow doesn’t move.”
* Tech Support: “Ok, last try, hit Ctrl-Alt-Delete again.”
* Customer: “Still nothing.”
* Tech Support: “Hit your numlock key. Does the light flash?”
* Customer: “No.”
* Tech Support: “Ok, you’re going to have to shut your computer off. Just press the power button, wait for a couple of seconds, and turn it on again.”
* Customer: “I’ve heard that’s bad for Windows.”
* Tech Support: “Um, well, you can’t do anything else, right?”
* Customer: “No.”
* Tech Support: “Well, you can’t hurt it any worse then.”
* Customer: “But I’ve heard it’s bad for Windows to just shut it off without shutting down first.”
* Tech Support: “Yes, but it’s locked up. There’s nothing else you can do.”
* Customer: “Will it hurt my Windows?”
* Tech Support: “Probably no worse than it already was by locking up.”
* Customer: “Well…ok…but if it doesn’t work, will you come over and fix it for me?”
* My Friend: “I just installed Windows 98.”
* Me: “Cool. But…it’s 2001. Why not Windows 2000 or wait for XP to come out?”
* My Friend: “Oh, 98 is more easily hacked, so I want it.”
* Me: “You want to get hacked?”
* My Friend: “Yes! Wouldn’t you?”
* Me: “No….”
* My Friend: “When you get hacked you get a lot of money! That’s a good thing!”
* Me: “???”
A customer called in with modem problems.
* Tech Support: “Ok, we’re going to check your modem settings. First thing we need to do is make sure all programs are closed.”
* Customer: “How do I know if everything is closed?”
* Me: “Make sure all windows are closed.”
* Customer: “But…I’m in the basement. I don’t have any windows here.”Lucky me, I made it to the the mute button in time!
* Customer: “I installed Windows 98 on my computer, and it doesn’t work.”
* Tech Support: “Ok, what happens when you turn on your computer?”
* Customer: “Boy, are you listening? I said it doesn’t work.”
* Tech Support: “Well, what happens when you TRY to turn it on?”
* Customer: “Look, I’m not a computer person. Talk regular English, not this computer talk, ok?”
* Tech Support: “Ok, let’s assume your computer is turned off, and you just sat down in front of it, and want to use it. What do you do?”
* Customer: “Don’t talk like I’m stupid, boy. I turn it on.”
* Tech Support: “And then what happens?”
* Customer: “What do you mean?”
* Tech Support: “Does anything appear on your monitor? I mean, the TV part.”
* Customer: “The same thing I saw last time I tried.”
* Tech Support: “And that is what?”
* Customer: “Are you sure you know what you’re doing?”
* Tech Support: “Yes, sir. What is on your screen?”
* Customer: “A bunch of little pictures.”
* Tech Support: “Ok, in the upper left corner, do you see ‘My Computer’.”
* Customer: “No, all I see is that little red circle thing with the chunk out of it.”
* Tech Support: “You mean an apple?”
* Customer: “I guess it kind of looks like an apple.”Then it took me fifteen minutes to convince him that he had a Mac. Even after showing him “About this Macintosh.” I spent another fifteen minutes trying to convince him that Windows 98 wouldn’t work on his Mac. He said it should work because Windows 98 is for PCs, and he had a PowerPC. I think he’s still trying to get it to read that CD, because I never could convince him.
* Tech Support: “Do you have any windows open right now?”
* Customer: “Are you crazy woman, it’s twenty below outside…”
For my work-study job, I work tech support at a small college. One night I was working Help Desk and the phone rings. I pick it up to have a student telling me she can’t get the computer to work.
* Me: “What operating system are you running?”
* Student: “Hunh?”
* Me: “Do you have a Mac or a PC?”
* Student: “Um, I don’t know.”
* Me: “Ok. What does the screen look like?”
* Student: “It’s yellow.”
* Me: “Ok. What does it say on the computer CPU?”
* Student: “What’s that?”
* Me: “The big grey box.”
* Student: “It doesn’t say anything.”
* Me: “Never mind that…do you have a little ‘Start’ button at the bottom of the monitor?”
* Student: “Monitor?”
* Me: “The thing that looks like a TV sceen sitting on the grey box.”
* Student: “Oh! That! No. No start button.”
* Me: “Ok. Is there a little apple symbol anywhere on the screen?”
* Student: (very puzzled) “Why would I have fruit on my computer?”
I saw two older looking ladies trying to figure out the computers at a local store. I knew one of them would say something that I could send to Computer Stupidities, so I tried to listen in.
* Woman 1: “What is that little trash can on the screen?”
* Woman 2: “My son says that is call the ‘recycle bin’. He tells me when I don’t want a Word document anymore and I delete it, it really goes in there.”
* Woman 1: “Why in the recycle thingy? Can’t you just erase it?”
* Woman 2: “Oh no, Word wouldn’t work for very long if I did that, I would run out of blank pages.”
* Woman 1: “Why?”
* Woman 2: “Because it cleans the words off the pages, then sends the blank sheets back to Word so they can be used again. That’s why it’s called the recycle bin.”
* Customer: “Something’s wrong with my computer.”
* Tech Support: “Like what?”
* Customer: “When I turn it on the screen goes all black.”
* Tech Support: “Totally black?”
* Customer: “Yes.”
* Tech Support: “Does it say ‘C:\>’ in the corner?”
* Customer: “Yes.”
* Tech Support: “Then it’s not really all black, is it?”
* Customer: “I guess not.”
* Tech Support: “Type ‘win’ and press the enter key.”
Talking to a Mac user:
* Tech Support: “When was the last time you rebuilt the desktop?”
* Customer: “Did what?”
* Tech Support: “How long have you owned this computer?”
* Customer: “Four years.”
A customer walked into the computer store I work in, wanting to return a computer.
* Me: “Sure, is it defective?”
* Customer: “No, that’s not the problem. When I took it home and turned it on, I realized it was only half programmed.”
* Me: [scratching head] “What do you mean by half programmed?”
* Customer: “Well, look at the computer on display.” [points to the Windows 98 desktop] “Do you see how all the programs are on the left side of the computer?”
* Me: [biting tongue] “Well, you are right sir, I will take your computer back.”I decided the moron had to solve his life before he could buy a computer.
Back in the early days of Windows 95:
* Customer: “I have Windows Thirty One.”
* Tech Support: “Ok, this program requires either Windows 95 or Win32s. Do you have Win32s on your system?”
* Customer: “No, I have Windows Thirty One, not Thirty Two.”
* Tech Support: “Windows 3.1 is the operating system. Win32s is a program that makes your computer fast like Windows 95.”
* Customer: “What’s Windows Ninety Five got to do with it?”
* Tech Supprort: “You need either Windows 95 or Win32s to run this.”
* Customer: “I HAVE THIRTY ONE! WHY WON’T IT WORK?”
* Tech Support: (giving up) “Ma’am, your computer is too old. Buy a new one with Windows 95.”
* Customer: “I’ve heard about Windows Three Hundred and Eleven. Wouldn’t that be better than Ninety Five?”
I was calling to sign up with a new DSL provider. When the guy asked what operating system I was using, I said, “Linux.” I was put on hold for five minutes, and then a supervisor came back and told me, “You can’t use Linux to connect to the Internet. It’s a hacker tool, anyway.” I almost fell out of my chair.
* Customer: “How much do Windows cost?”
* Tech Support: “Windows costs about $100.”
* Customer: “Oh, that’s kind of expensive. Can I buy just one window?”
To be continued.

View high resolution youtube videos
Normal resolution
Normally the youtube url looks like the one below which gives you low resolution 320×240 videos.
http://youtube.com/watch?v=XYZXYZ
High Resolution
Simply add &fmt=6 onto the end of url
http://youtube.com/watch?v=XYZXYZ&fmt=6
Now you should see high resolution videos. If no change is observed, then it means the video has not been converted to the higher resolution yet. View the video in full screen mode to see the difference.
If you add &fmt=18 to the end of url.
http://youtube.com/watch?v=XYZXYZ&fmt=18
Now it will play the high-resolution 480×360 MP4 high-bandwidth videos with higher quality audio when available, otherwise it will play the regular version. Give it a try.

chmod recomandat la fisierele hostate pe apache cu suexec
In cazul in care aveti web hosting pe un server bazat pe apache cu suexec, permisiunile recomandate sunt 755 pentru directoare si respectiv 644 pentru fisiere. Daca aveti acces ssh, schimbarea recursiva a permisiunilor se face astfel:
755 pentru directoare:
find . -type d -exec chmod 755 {} \;
644 pentru fisiere:
find . -type f -exec chmod 644 {} \;
unde . reprezinta directorul curent de unde va incepe cautarea. Acesta poate fi inlocuit cu o cale absoulta de genul /var/vhosts/example.com

FireHOL R5 v1.255 – un update indelung asteptat
Ar fi fost pacat ca acest minunat “firewall builder” pentru iptables, sa ramana neintretinut. Cu toate ca nu a mai fost updatat de aproape 2 ani, prim modul ingenios in care a fost creat, chiar si in versiunea 1.226, este de neinlocuit. Singura data cand am avut o surpriza neplacuta, a fost acum cateva luni cand o parte din ip-urile rezervate au fost vandute si au devenit publice. (De exemplu clasa 74.0.0.0/8, din care 74.56.0.0 – 74.59.255.255 apartine Le Groupe Videotron Ltee, un important isp din Canada. Va dati seama ce a insemnat sa fie filtrate teoretic aproximativ 16777214 hosturi, printre care se afla si propriul server)
Pentru a fi mai usoara gestionarea acestor tipuri de adrese, in FireHOL R5 v1.255 au fost introduse definitiile externe pentru RESERVED_IPS, PRIVATE_IPS, MULTICAST_IPS, UNROUTABLE_IPS in /etc/firehol. De asemenea firehol avertizeaza daca RESERVED_IPS sunt mai vechi de 90 de zile.
Updated services: nfs, OSPF, sip, vmwareweb.
Adaugate protectiile: bad-packets, all-floods.
Adaugate actiunile: tarpit.
Adaugat suport pentru recent iptables module.
Adaugat addrtype (srctype, dsttype) support in optional rule parameters.
