Imagine the whole world black out for 2 minutes. What might be the consequences? Now image you know what is going to happen on a specific day six month on. Would you change your present to avoid or achieve that future? Is our fate written? This TV series, based on Robert J. Sawyer’s sci-fi novel of the same name, focuses on this matters and promises to become a breathtaking hit.
Besides of its interesting plot Flashforward can also help you to learn English. Just read these five words or phrases I learned:
- Flashforward = Transition (in literary or theatrical works or films) to a later event or scene that interrupts the normal chronological development of the story.
- Atone= To make reparation, compensation, or amends, for an offense or a crime. Example: How do I atone for something I haven’t done yet?
- To be loaded = (Slang) Drunk or intoxicated. Example: Why can’t you remember everything? Becuse I was loaded.
- Give up on = Lose faith in or stop believing in something or someone. Example: Bryce, don’t give up on me!
- Things go south = when the situation turns bad. Example: If things go south, you’re definitely gonna need to keep carrying a gun.
I just finished watching the forth season of Dexter and here are five words or phrases I learned:
- Fender bender = A minor accident that generally causes minor damage to the vehicles involved, but can still become a major issue for the owners of those vehicles.
- Padlock = Portable lock used to protect against theft, vandalism, sabotage, espionage, unauthorized use, and harm.
- Fuckward = One who is an annoying moron
- Kismet = Fate, destiny
- Bode = To indicate by signs; to foreshow. Example: That bodes well
You can learn a lot by watching TV series and movies…but remember to put your subtitles in English!
I installed my sister’s computer at least four times with Windows XP because it got viruses…I hope this time they consider to use Linux (they have it installed but they don’t use it)…When they come to pick the computer up, I’ll will comment to them that I’ve never had to install my PC since I installed it Debian.
Sorry, this entry is only available in Español.
This is my 100th post! When I started writing on my blog, some friends asked my if I would have enough material to post…the answer is yes! If you work with Linux and Software Libre you always have something to share with. But not everything has been about Linux or Software Libre, I’ve also post some things I do on my spare time like what I play on my PSP and PS3, or things that happen to me!!
So, there will be more posts to come :)
If you get on Caracas’ subway, you better be ready to be asked for money, specially if you travel between Agua Salud and Parque Carabobo stations, because there is a new way of making a living for many unemployed people.
I’ve seen almost everything: people gathering money to bury their dead, a guy with elephantiasis (he claims it’s just a swollen leg), a very persistent old lady asking for just a coin (believe me she is persistent), funny rappers, a guy who claims he has skin cancer and AIDS, a woman who also claims she has skin cancer (I don’t know whether it’s true or not, but she has been asking for money for at least ten years) and now trying to rap because she says rappers earn more money than she does), musicians with guitars, bongos, cuatros and even harps.
If you wonder if it is worth the effort, just see the above picuters. You will see two rapper counting their money. At a glance I estimate they had at least Bs. 250 (between $40 and $100)…it’s not bad for a day work, is it?
If you are interested in learning a new language, here’ s a creative alternative: Livemocha. It’s a Facebook alike service but focused in learning a new language. You can enroll to a basic course to follow a series of lessons . Each lesson is made up of four sections: Learn, Review, Write and Speak.
In the Learn section you follow a kind of flash presentation with the things you are suppose to learn. In the Review section you do some exercises related to the Learn section to reinforce what you’ve just learned. The Write section aims to improve your writing skills. Finally, the the Speak section is designed to improve your pronunciation by making you read a text while you record it.
FTP is a TCP service that uses a data port and a control or command port. Commonly those ports are 20 and 21, respectively. But it’s not always that way…specially if you are behind a firewall.
Let’s see how ftp connections works normally:
- The client connects from a random unprivileged port (N >1024) to ftp server’s command port (21)
- The client starts listening on port N+1 and sends this ftp command port to the server
- The server will connect back to port N+1 from its data port (20)
Here is a connection example:
- Client’ s command port (1026) connects to server’s command port (21) and sends data port 1027
- Server sends back an ACK to the client’s command port
- Server starts a connection between its data port (20) and client’s data port (1027)
- Client sends an ACK to server
The active mode has a problem, if the client is behind a firewall the server won’t be able to establish a connection to the client’s random data port (the one which is above 1024). In order to fix this problem, there’s another connection method called passive FTP:
- The client opens two random unprivileged ports (N > 1024 and N+1)
- The first port (command port) connects to port 21 on server side (command port) and sends a PASV command
- Then, the server opens a random unprivileged port (P > 1024) and sends the PORT P command back to the client
- Finally, the client starts a connection from port N+1 to port P on the server to transfer data
Here’ s an example.
- Client’ s command port (1026) connects to server’s command port (21) and sends PASV command
- Server replies to the client with port 2024, the random data port opened for data connections
- The client starts a connection from its data port (1027) to server’s data port (2024)
- Finally, the server sends back an ACK to the client’s data port
According to Wikipedia: “RAID is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives. The different schemes/architectures are named by the word RAID followed by a number, as in RAID 0, RAID 1, etc. RAID’s various designs all involve two key design goals: increased data reliability or increased input/output performance. When multiple physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk. RAID can be set up to serve several different purposes”.
The distribution of data across multiple drives can be managed either by dedicated hardware or by software, or even by hybrid RAID based on software ad specific hardware.
According to the RAID you choose, these are some RAID’ s features:
- Data reliability
- Better fault tolerance
- Better performance
- More space
- Integration of low cost disks
Original RAID’s specification suggested some numbers called “RAID levels”, each of them with theoretical pros and cons. Over the years, different RAID concepts have appeared, but most of them differs substantially from the original RAID levels, but it’s still common to use a number (e.g, RAID7)

Yesterday I was walking through Millenium mall (Carcas, Venezuela) and I came across to a kind of game-station. Basically it’ s a stand with four tv sets, four game consoles (two Wiis and two Xboxes) , four wireless guitars and a wired drum.
They rent the console and the game for 15min at Bs. 10 per person or Bs. 15 if you use a guitar or the drum.
A saw it and thought it was an innovative idea, so I decided to take some pictures. While I was doing so one clerk told me not to take pictures or record videos (in fact she called a mall cop).
What do they hide?
- Do they work with pirated games? (yes, I saw some copies.. legally made?)
- Can they use games in such a way? (I guess not, read game’s licenses)
- Do they pay all their taxes?
- Do they think somebody is going to copy their “innovative” idea? (well, it’s not that innovative after all)
P.S: If that chick had been less rude, this post would been complely different…bad for GameBox!!
