Google: Eric Schmidt to step down as CEO; Larry Page (co-founder) to replace him

2011-01-23T02:26:00.000+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Noooooo.. What did I say? Noooooo...

Indeed, Eric Schmidt is to step down as CEO in April 2011... I've just stumbled on an article on TechCrunch [article] and said to myself: What? Is this true? Wtf?

Searched a bit inside the The Official Google Blog and what do you know? - it IS true [Google Blog: post]

Hey, it's even on Twitter [post] :)) Eric on Twitter - that's such a great joke given some of his speeches / interviews / key notes... Wait, Eric Schmidt has a twitter channel? [channel] Funny, I've heard him many times mocking Twitter. A ha ha :)) What next? He'll become an active Facebook user? :))

All in all, my personal opinion (published on my computer science blog [1]) is that Google has become what it is today due to Eric's skill as a leader - I've watched may presentations and/or interviews of him in the last 2+ years and I'm impressed by his skill and intelligence.

I see his leadership and management style [2] to have been and still be the force which manages Larry, Sergey and developers' energy, ideas and desires to aim sky high. He took the company from a 200-employees start-up and developed it into a super power - indeed, he had brilliant developers to work with, constantly hired new brilliant developers, empowered innovation etc. - I see all these as big pluses.

I regret Eric Schmidt is leaving [4], but am also curious on Larry Page's [3] leadership impact on the innovation pattern of the company. Thanks Eric, good luck Larry!

Wait, April 4th they said? That must be wrong - I surely hope they meant April 1st :)) Really!

A great funny comment on TechCrunch - I removed the Caps and some words, while inserting a couple new words to make it funnier:

Apple: wowowow, omg billions billions billions. Increase of X, increase of Y, omg Apple is blowing people out of the water. Buy, buy, buy!... oh and CEO is taking medical leave and leaving the company in the hands of a longtime business partner that nobody has heard of since... wait, what's the other Steve's name?...
Google: earnings are quite good, but...that's just secondary... omg the CEO is stepping down and leaving the company in the hands of one of its co-founders, also his 10-years business partner and actively working at Google’s day-to-day operations, and omg the world is so going to end. Sell, sell, sell!

In the news

Guardian's take on the subject [Guardian: article]

Ok, they talk again about spam in search results... Have they tried Bing? It's worse :))
Are they idiots? All they see is search and Android as successes? Well, there's also

GMail - btw, the anti-spam service is great; really, try Yahoo, Hotmail etc. and then tell me your opinion
Calendar
Reader
Translate - I wish I had this when studying French in highschool :)) Oh, yeah, that would've been awesome.
Docs
Maps
YouTube (they bought it, yes, but improved it a lot)
Picasa
Analytics (bought it, but improved it a lot)
Blogger (bought it, but improved it a lot)
Google Apps - Hey, I run both my domains on Apps and I'm grateful for the free service

plus there are some I never tried, but seem great given the demos during Eric's speeches and/or separate presentations/demos:

Goggles
Voice search
Voice real time translation
Google App Engine

and the 2 lists could go on...

Why does Guardian say that? Because the new hype is social. Oh gi'me a break!
Social is and will be cool.
Social is and will be a great feature of the future development of Internet, indeed.
However, ignoring all other aspects of our lives looks stupid to me.

The Guardian: Such a laissez-faire attitude won't work once you get bigger, as the Buzz example shows. - Congrats Guardian for killing the innovation spirit. We appreciate it! Hey, grow up, failure is part of life; one has to try multiple times in order to get it right!
I, for one, surely hope Google to keep & improve this laissez-faire attitude in order to deliver more great & free products/services!

[1] That's a subtle joke, since I have 2 blogs: one treats my personal (but not too personal) life, and the other one treats computer science-related topics. Now you get it? A personal opinion on the computer science blog :)

[2] Hey, Eric Schmidt had successfully lead big projects and/or companies before - [Eric's bio at Google; Wikipedia: Eric Schmidt]

[3] Side note: Hey I never noticed that PageRank [Wikipedia: PageRank Algorithm] is called after Larry Page - I've always interpreted page as page [M-W: page] - always analyzed how things worked, but rarely paid attention to where the naming comes from. I can barely stop laughing now.

[4] Am I too old to accept the replacement of people I admire? Have I grown too old already not to take a huge leap towards innovation?

MacBook Air & iLife '11 & Mac OS X 10.7 Lion [News]

2010-10-31T13:34:00.005+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Did you know that Apple launched the new MacBook Air [Apple section on MacBook Air]? I only found out recently. It looks slimmer [design], has some nice features [features] and specifications [specifications].

I've watched the short video [Apple] and the ad [Apple] for the new MacBook Air - nice.

Steve Jobs' et. al. 90 minutes keynote-on-everything [Apple] crashes Firefox 3.6.12; Safari 5.0.2 plays it, but there are no controls, i.e. there's no way to skip ahead or go back to some point of the video or the stop/pause options hardly work. Wtf? Did anyone watch this in the browser? Could this be happening due my slow Internet connection?

Solution: I finally downloaded the .m4v file [Apple link] of the keynote - it works perfectly. If interested there's also a RSS with all Apple keynotes [Apple RSS].

Opinions/Comments on:

iLife '11:

iPhoto - bla bla, whatever
iMovie - nice; I already like iMovie '08; the latest should obviously be better
GarageBand - looks nice; only played a little bit with '08, but I should play more

FaceTime: ok, may look nice, but I still like it in-the-browser like GTalk or the standalone Skype; probably Android devices will get some GTalk-like capabilities, I don't know
Mac OS X 10.7 Lion: looks nice, pretty cool (App Store, Mission Control)
The new MacBook Air: starts at 1:12:00; quite nice, see below. I expected more details (i.e. more bragging like amazing-awesome-beautiful) on this puppy.

The funny summary [YouTube] of this keynote - indeed, a great-nice-beautiful-amazing-phenomenal-awesome summary. You'll laugh quite a lot. [reached there via LifeHacker]

The New MacBook Air

Pro: Solid State Storage

It was about time computers gave up hard disks, which have mechanical parts therefore break too often. It is the time now also because flash memory offers an affordable price & high storage capacity.
N.B.: Affordable does not mean cheap, but cheap enough for some to buy. 1-2 years from now it shall be cheap enough for everyone to buy. Great!

Pro: multi touch with many fingers in many ways [Features - the pictures at the bottom of the screen: 2 series of 5 pictures]

Con: 13 inch screen

I still like MacBook Pro's 15 or 17 inch screen [Apple]. Maybe I'm just an old fashion guy, I don't know, but I like a big screen.

Con: No CD/DVD drive in the Air generation

Never liked that missing. However, I must say Apple does a pretty stupid job with that SuperDrive anyway, i.e. the native API of MacBook Pro does not allow one to read/write a multisession CD/DVD [1] etc. - yes, Windows's Nero [official site] is one killer app that makes a Windows PC much better than any Mac OS X MacBook Pro. So, there's not much to miss about Apple's (lack of) support of CD/DVD - on one way, it's better they have removed the SuperDrive.

Specifications [specs] - CD/DVD sharing: Without a built-in optical drive, how do you install new applications? Simply use DVD or CD Sharing. This convenient feature of Mac OS X lets you wirelessly “borrow” the optical drive of a nearby Mac or PC. So you can install applications from a DVD or CD and have full access to an optical drive without having to carry one around.

Installing a fresh OS works too, but there seem to be some hiccups [article]. Anyway, Air looks nice, i.e. it is a beautiful-great et. al. product :))

[1] Ok, you can write a multisession DVD only in Apple's special-whatever-way, or read a multisession CD/DVD if it has been written on PC in UDF format. PC Joilet - no way, not with MacBook Pro at least. I still throw bad words (and grow white hair) for that at Apple and praise Windows. And Apple calls the unit SuperDrive - oh, spare me! I'd rather call it ShitDrive! No joke on that.

Google Buzz - get it out of my inbox

2010-07-15T19:07:00.001+03:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Like most Google Buzz (launch event video) users I've been buzzing around, i.e. sharing stuff and commenting with my friends. It was and still is quite fun but there's a problem.

Problem 1 (P1)

Google Buzz notifications appear in inbox, making the inbox unpleasantly crowded with useless details.
Note: Friends' comments through Buzz are useful, but not in my inbox! When Buzz comments get into my inbox, they become annoying and useless.

Solution to P1

Go to GMail > Settings > Buzz > Buzz in your inbox and uncheck all those 3 boxes. That's it.

Problem 2 (P2)

When my friends comment in Google Reader, the comment appears both in Google Reader and Google Buzz. It's unpleasant to read it in Buzz, but not be considered as read in Reader.

Solution to P2

I don't know yet.

GMail - Has someone hijacked your gmail account and is now sending emails on your behalf?

2010-07-11T20:20:00.000+03:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Problem

What if a malicious hacker/spammer has hijacked your gmail account and is now sending emails on your behalf? Besides privacy violation, your account will also get marked as spammer and all your e-mails will get in the spam folder of your recipients.

Solution

If they have also changed your password, then you have a problem which I do not know how to solve - technically you need to contact GMail administrators. Good luck!

For the rest of the post I'll consider the case in which you still have access to your account, i.e. the password has remained the same:

Make sure your account has really been hijacked.
Read thoroughly the Google Help page explaining what to do when Someone is sending from my address - also click on each of the 3 links at the end.
If you can confirm spam has been sent through your gmail account, then the useful link is My Contacts say I sent spam to them, or I found suspicious access to my account.
Report it to Google.

Otherwise, just to keep yourself safe, make sure you set your browser's connection to always be https. For example, looking at my account's settings I noticed it had none of the always use https and don't always use https options set, which I suspect to be because it's a very old account; my friends' old accounts were the same.

Hope this helped you in case you were in trouble.

Flash - my opinion: Adobe shall have to reinvent Flash in order to save it

2010-06-04T23:24:00.003+03:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

This post is about Flash - my opinion:

There's an entire discussion on whether to support or not Flash. Google (at I/O 2010 for example) picks on Apple for not supporting Flash... well, I'd say Apple announced this too early, just that. If Apple had only waited some 1-2 years, it would have been ok.
Oh, and they can't just ignore Flash when launching something [ugly, useless, expensive] like the... iPad.
Why was it only later that Steve Jobs provided a full reasoning?

I must admit that Eric Schmidt is kind of evil in the Google I/O 2010: Google TV Keynote, Day 2 - CEO Partner Panel - we all know that HTML 5 will kind of make Flash obsolete. If you've read my 2009 I/O post, you've probably watched the I/O 2009 Day 1 Keynote which talks about offering pixel level control in-the-browser... right? (Anyway, start watching again at 18:31)

Also, in last year's keynote - this is going to be SO FUN!...

Skip to 19:08 and listen the reasoning with respect to the Canvas... [...] just use silverlight, vml or flash... but what if we wanted something that was part of the open and transparent internet that we know and love? Now, is it just me hearing this or has Mr. Gundrotta just said Flash was not open and transparent in 2009? :))

19:48 - drawing and animation APIs with pixel level control.
Now, what will Flash be used for? I don't know.

You can stop at 29:50.

Hey, watch another demo of in-the-browser capabilities - nothing fancy, just...
The Quake II GWT port brings the 3d gaming experience of Quake II to the browser.
And the video... http://www.youtube.com/watch?v=XhMN0wlITLk
Cool? I'd say yes.

Conclusion

Now, tell me, what shall we need Flash for?
I don't know. Not now. Maybe later I can come up with some ideas.

I say that Adobe shall have to reinvent Flash in order to save it. Until then, it must be supported - Apple should have supported it, and Google is [almost] right when picking on Apple. However, if Google supports Flash now and ensures that Flash shall not be reinvented... :D... then Flash shall disappear in the next 2 years...
I still wonder on whose side Google is...

Google I/O Day 2: My opinion(s) on 2 keynotes: Android demo, Google TV keynote & CEO Partner Panel

2010-05-28T22:36:00.003+03:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Main ideas

The Android platform is really cool - it will (1) do more than I thought and (2) work on more than just the phone.
Apparently Android and Chrome go hand in hand.

Doh! It should have been obvious... well, I did not foresee all these...

Google I/O 2010 - Keynote Day 2 Android Demo - Full Length

They just love picking on Apple :)) continuously.
I think this keynote got Steve Jobs a bit nervous: Hey, stop picking on us, 'cause we create beautiful devices, probably he said to himself.
I agree that the iPad itself appears to be crap (although I haven't tested / played with it), but not supporting Flash... well, you'll have to check my next post for the opinion on that...
Other than that, indeed Google has a strong point picking on Apple, e.g. the multitasking part missing from the iPad.

Anyway, the Android platform is really cool. You really need to watch the keynote. The demos will get you impressed.

Tethering done by Android devices? Cool. I bet the iPad appreciates it :)

The bug reporting feature for Android Market apps - cool.

Regarding making money, the new Google Mobile Ads approach seems cool. (Ok, I've read about some of these formats on Google's blog and/or saw them on presentations on YouTube etc. However, now I've seen for the first time a live demo with respect to a mobile device.)

Google I/O 2010: Google TV Keynote, Day 2

Note: It's a list on YouTube for now. I wish they had glued all videos into one big, continuous, easy to watch video. I'll post an update in the future if they do that.

Smart move from Google to enter the TV market. Really smart.
I bet their analytics will redefine what we call now rating and/or TV advertising. All the apps and features are (and will be) cool, people might appreciate them and so on, BUT the killing feature will be the analytics in my opinion. I'm curious on what the data about the advertising TV market will look like in the next 1-2-3 years.

Too bad the TV is dead and buried :) - let me explain:

My generation and all following don't want a TV at all, since we have the Internet and complete all our tasks using portable hardware/devices (laptop and/or smartphone).

In the paid-TV system, I won't search for (1) a video/movie on the TV and/or (2) a channel's schedule, using the keyboard and/or other peripherals they envision - I'll search it on the net from my portable device and then request to be sent to the TV to be played... Most likely I won't even call it TV, just something like: You know what? Don't play it on this small screen, send it to the big screen/display in the living room.

My generation envisions the whole TV system as an old technology, in which we, as customers, are powerless since the both content creators and distributors used to big & bad, but only now they have become an adorable puppy or pussy-cat etc. because the Internet communication paradigm has left them with no choice.

Will Google TV make it all easy and fun? Maybe.
I personally desire only one feature: to push video content from a portable device to the TV.

Google I/O 2010: Google TV Keynote, Day 2 - CEO Partner Panel

Picking on Apple again? Yes. Of course. Why not? :)
Anyway, it's a nice many-CEOs-discussion. Everyone's so happy and joyful and complementing everyone else... I had several doubts I was attending a technical presentation vs. only-marketing-and-PR talk.

Did you notice the moment when the Best Buy CEO said dominate? :D It was so funny!

Conclusions

Android? I have a feeling technology is moving too fast at this moment; never have thought of saying this...

Chrome? Now I understand why Google started making their own browser - obviously, they need a whole platform (ok-ok, you can [still] say it's a browser) that they can develop really fast, implement on it exactly what they need and deploy applications on top of it.

Stay tuned, 'cause the next post will be about... Flash, since Apple's move has drawn kind of a lot of attention.

Google I/O 2009 keynotes and "resuming video" feature in YouTube

2010-03-29T00:41:00.002+03:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Indeed, it was about time I watched the 2 full keynotes of Google I/O 2009. (For the record, I have watched bits and pieces over time, so I wasn't that lazy, but never actually watched the 2 full keynotes, so I was lazy to some degree.)

Anyway, here they are for the ones too lazy to click on the Google I/O 2009 page:
Google I/O 2009 - Keynote Day 1 (full)
Google I/O Day 2 keynote - Google Wave Developer Preview at Google I/O 2009

On this occasion, I've noticed YouTube has introduced a new feature I had no idea about - resuming video... - should one stop watching a video and minutes later reopens it, then it resumes from where one stopped last time. Pretty awesome I might say. - Did I say new? Well, it appears it has been launched quite a long time ago - if interested, see the post with the detailed description of the feature on YouTube's official blog - the "Resume where you left off" paragraph of the post.

Google Maps problem

2010-03-22T15:42:00.001+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Apparently there's a Google Maps bug that screwed up a bit my Netherlands map.
Cool bug - due to all entries having the same place details (this is the bug), all my entries show the link to my latest NL blog post now! I shall feel sad when they fix it but happy that my map will be correct again...

Firefox 3.6 runs very slow - Solution

2010-03-18T16:58:00.003+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Problem:

I've installed some 2 days ago the Firefox 3.6 and noticed several problems:

GTalk: first, it took some 1-2 minutes to detach/pop-out the window when video conferencing, then when it finally did it, the conference got ended due to some error - this was extremely annoying
Opening pop-out pages became extremely slow, somewhere between 30 seconds and 2 minutes

Solution:

Research:
I've read a lot of googled solutions, none worked.
I've installed Firefox 3.5.8 and then 3.5.6 and the problem persisted - that was strange, since 3.5.6 surely worked.
I suspected (frightening!) problems due to interpreting JavaScript or whatever, which in turn (even more frightening!) could be because I've installed recently some cool stuff, i.e. MacPorts.
I've tested the same pages with Safari and everything worked fine.
Then finally the solution hit me...

Actual solution - short and simple:
It was because of the extensions I've installed some time ago.
Really!
I went to Tools > Add-ons > Extensions and just uninstalled all of them; all pages seem to load fine at the present time.
Therefore I'm running Firefox 3.6 with no extensions.

Now surfing life is again fast and pretty.

MacPorts, Xcode, gnuplot

2010-03-11T15:40:00.002+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Problems on a Mac OS X 10.5:

P1: One needs to install on Mac OS X commands like calc, wget (although Mac offers the equivalent curl) etc.

P2: One needs to install gnuplot (wikipedia on gnuplot), but would prefer not to go through all the steps (i.e. configure, compile etc.) with the source code of gnuplot.

Solution:

First, install MacPorts. According to Wikipedia, DarwinPorts has become MacPorts - I recommend the easiest installation possible, i.e. Mac OS X Package (.pkg) Installer.

Second, get familiarized to using MacPorts, by reading that specific part of the manual describing the port command.

From now on, you should install the piece of software causing your problem:

P1: calc, wget etc.
sudo port install calc
sudo port install wget

P2: gnuplot (It will be installed in the same way as above, but I encountered a few problems)

When I first tried to install it, I encountered an error:
On Mac OS X 10.5, gnuplot 4.2.5 requires Xcode 3.1 or later but you have Xcode 3.0.
Error: Target org.macports.extract returned: incompatible Xcode version
Error: Status 1 encountered during processing.

, so I cleaned the failed installation:
port clean --all gnuplot

Given the error, I uninstalled Xcode 3.0 (pages on uninstalling Xcode: 1, 2, 3) and installed Xcode 3.1.4 which I've downloaded from Apple.

Then I ran the selfupdate for MacPorts

sudo port selfupdate

and checked for outdated ports

port outdated

but there weren't any, so there was no need to upgrade any installed ports.

Should you find any outdated ports, just run (as it recommends when finds those outdated ports)
sudo port upgrade outdated
You can also use the other command, which tries to upgrade all installed ports
sudo port upgrade installed

Then I finally installed gnuplot

sudo port install gnuplot

in order to upgrade all your installed ports and their dependencies.

Feel free to check its man page, or type gnuplot in terminal etc.

End.

How to download embedded content in webpages

2010-02-12T19:00:00.005+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Problem

Would you like to download content (audio, video) embedded in web pages? e.g. YouTube, Trilulilu etc.

RO: Cum downloadez un cantec (fisier audio) dintr-o pagina Trilulilu, sau un film (fisier video) dintr-o pagina YouTube etc.?

Solution 1

I've found a page describing how to do it, but now let me tell you the long story, i.e. my approach, because it's nice, harder and doesn't always work - indeed, CS people have a funny sense of humor.
The truth is this is the first solution I've tested:

First, install in Firefox the add-ons called FireBug and DownThemAll.

Second, open the page with the targeted content. Click on the little bug (because we use FireBug now) found at the bottom of the window, on the right side; click Net, click Enable, reload the page. Then sort the links by the downloaded size of content, i.e. click Size - now all links are displayed in descending order of the loaded content size. The first link(s) should be the one(s) you're interested in. Copy them, one at a time.

Third, Tools > DownThemAll > Manager > Add URL - insert here the links you've copied at the previous step. Download the content corresponding to each link, rename appropriately, i.e. if you've downloaded an audio file from Trilulilu then rename so the downloaded file ends in .mp3

Solutions 2, 3 (easier solutions)

Fast Video Download - good add-on for downloading videos embedded in a web page, e.g. YouTube.
Just click on the blue icon at the bottom of the window, on the right side, or in the upper right side of the window.
I recommend you disable Hover menu icon, i.e. the blue box which appears when you select some text, like this: Tools > Fast Video Download > Fast Video Download options > Settings > Search Menu Advanced > click to uncheck Hover menu icon.

FlashGot - a very good add-on.
Just click on the blue icon at the bottom of the window, on the right side - it shall download all content.
I recommend it if you desire to download audio files from Trilulilu, for example.
I also recommend you deselect Autostart downloads: Tools > FlashGot > Autostart downloads (click to deselect it, id it appears selected) or Tools > FlashGot > More options > Downloads > make sure Autostart downloads appears unchecked.

Conclusions

I recommend you use (1) FlashGot, or (2) Fast Video Download.

FiraBug could be useful for debugging or other more complicated tasks, but not for this solution.
Also, DownThemAll might prove useful in the future.

Share your Google Reader shared items to a website / blog / feed reader etc.

2010-02-10T16:24:00.000+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

Problem:

Have you ever wanted to share your Google Reader shared items with the world, by inserting them in a website/blog?

I have wanted that since I started sharing items: hey, if I share something, let the world know it and read all shared items, since they might find it useful!

Solutions:

Solution 1: RSS feed
At some point, I inserted on my professional website a link to my shared items' RSS feed.
The RSS feed can be found on the page with your shared items, if you made them public: Settings > Reader settings > Folders and Tags > View public page >Atom feed.
Downside: that does not make too much impact, doesn't it?

Solution 2: Add a clip with your Google Reader shared items to a website or blog
Later, I saw this cool feature in Google Reader of adding a clip with your Google Reader shared items to a website or blog and realized I wanted to display them on my personal blog. So, I created the clip - that was some 6 months ago or more.
A few days ago, a friend asked how I did that, so I searched for the feature and found the solution described in Reader's Help: How do I add a clip to my website or blog? - note that Tags in now called Folders and Tags. Afterward, configuring your clip is straightforward.

Solution 3: Send to...
This is new apparently: Settings > Reader settings > Send to. From there you can choose some predefined websites or add your own.
Each time when sharing something, on the same row with Share, Share with note etc. you also have the option Send to - last one in the right.
I tested it a bit with Facebook, but it either makes things appear unattractive/unpleasant in my profile (e.g. for Dilbert strips only a link appears) or Facebook crashes when hitting the button Share (e.g. for Academia Catavencu).
I do not recommend this feature for now: I'll further test it and recommend it once it behaves nice.

Steve Jobs, Bill Gates. Apple, Microsoft. Oh, and the iPad...

2010-02-03T19:05:00.004+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

A couple of days ago I've had an intense and exhausting 2 hours conversation with Andrei on the launch of the new iPad. (I recommend you watch the demo, which is short, and then the keynote, although it runs for 2 h.)

Andrei had a strong opinion on this, i.e. against the iPad, based on various comments on the web against the iPad. He later gathered all these links in a nice post against the iPad.

I've also shared with him a playlist I've compiled a long time ago, with the interview with both Steve Jobs and Bill Gates - it's a really great and inspiring interview, showing the spirit and leadership of these 2 prominent figures that have influenced the IT industry.
Andrei made several interesting comments I think are worth reading. Regarding the documentary, I've found both part 1 and part 2, but it feels like there's also a part 3 still missing.

The BBC podcast feed (interview section) that I've subscribed to presents a fresh interview with Bill Gates. Enjoy!

All in all, I think it's great we're part of the evolution of the IT industry. We should learn from people like Gates and Jobs, and from their products (be they mistakes or successes).

Thanks to Financial Times, I got informed on what has happened recently between Google and China; see the so called Google vs. China section on FT.
I will enumerate just a few articles I've read and found interesting:

My position is simple: I have always in the past and shall in the future (1) support competition and freedom (since I consider these the building blocks of our society) and (2) criticize any form of censorship and/or threat to competition.

2009-12-10T22:01:00.000+02:00

[Post published by Liviu on Liviu's [Computer Science] Blog]

I used to consider the Universe being huge and incredibly fast, i.e. the best invented thing ever.
Well, it's not that good. [Seth Lloyd, Abstruse Goose]

Therefore, it may require improvements. I'm thinking on writing a research proposal for a better design of the Universe. Cool, isn't it?

Q.1: I have one problem though: I can't find the instructions manual or the complete specifications. OK, nobody shall thoroughly read those anyway, but it would look bad not to reference them.
Does anybody have them?

Q.2: Who should I submit the proposal to? I'm not sure who's in charge of it all:
(1) God - How do I reach Him/Her?
(2) NSF, NASA, CIA or some other secret US governmental agency?
(3) European Space Agency?

Bucharest (capital city of Romania) on Google Maps

2009-11-20T17:52:00.002+02:00

Great! We finally have the map of Bucharest, the capital city of Romania, on Google Maps. Really, take a look!
Ok, Googe has to improve its street names, since Magheru Blvd. is currently Kiseleff, but hey!, it's a good start! I've been waiting for this for a long time!

Frauda (en: scam) super tare pe Orange, cu 2 telefoane deschise

2009-10-12T21:17:00.000+03:00

Ce s-a intamplat ieri

Imi povestesc azi ai mei ca i-a sunat ieri cineva (sa-l numim Trudy :D ca sa folosim limbajul din "Computer Networks", de Tanenbaum) in timp ce munceau prin casa. Nah, cand muncesti prin casa, nu te gandesti sa verifici identitatea celui care te suna, cand incepe direct si increzator ca e de la Orange etc.

Trudy initial a vrut sa stie numele celui cu care vorbeste (deci nici nu stia cu cine vorbeste!) si a pretins ca au vorbit mult cu Spania si Italia si au super factura de platit. Nu i-a prins, pentru ca ai mei n-au vorbit; nu permitea abonamentul telefonului, ha ha ha!

Apoi Trudy a trecut la ce-l interesa: daca mai au un telefon Orange si apoi sa-l deschida si pe acel celalalt telefon Orange si sa sune nu-stiu-unde. Li s-a parut ciudat. Totusi, au zis sa-l deschida, dar l-au inchis pe primul. Trudy s-a enervat (aici ai mei s-au prins ca e ceva dubios, si s-au oprit din orice), Trudy s-a speriat, a inchis.

Ai mei m-au intrebat pe mine, eu am google-uit. Si am gasit ceva destul de inteligent pe net...

Most remarkable inventions of the human species

2009-09-28T23:58:00.001+03:00

Indeed, I should have been taking a shower now so I could do my reading afterward, but given my mental status (i.e. stressed, angry et. al.), I decided to catch up a bit with all the Reader posts that piled up.

So, I came across xckd's post The Search, more specifically its tooltip.

So, here we are to the [rather funny] objective of this post, i.e. a Liviu index of the human species' most important discoveries/inventions (I have first written it as a funny comment on my shared items on Google Reader).

First, discovery/invention of the cat flap (by Sir Isaac Newton). I admit, it's taken from Hitchhiker's Guide, since it's brilliant. Go ahead, laugh!

Second, Sir Isaac Newton's (yes, he got second place too) Law of Universal Gravitation, so he could have a good explanation to present to his wife for his head getting hit all too often when standing under an apple tree. (It's gravity, for God's sake, and even God cannot do anything about it.)
Update (Sep, 30th): since Sir Isaac Newton did not have a wife (see the first comment, thank you for pointing that detail that I missed) and Wikipedia concurs it, I must rephrase my theory: he developed the Law in order to have a good explanation to present to his lovers or mistresses. Now, since he didn't actually have a wife, the theory was either too bad for women to believe it, or too good and kept him both popular and trouble-free. (There's also the possibility he did not have any interest whatsoever in women, but that would prove boring to develop comments on.)

Third, Einstein's general theory of relativity, to prove, in part, to his wife that every time he had been late (just as I used to be many times) he has in fact arrived sooner. (One may find entertaining the relativity priority dispute, especially considering his wife was very smart also.)

Fourth, e-mail, so students can submit their assignments (homework) without having to come to school, therefore longer time intervals could be dedicated to even more assignments, improving both levels of education and stress.

Fifth, my favorite trio: electricity, computers and Internet - so everyone could have access to [and waste their short life with] unlimited knowledge and entertainment.
Knowledge implies studying/learning, and, since it gives quite nice headaches, most humans have learned to avoid it.
Entertainment implies the instant messaging services (text and/or audio and/or video), piracy (software, entertainment TV programs, movies, songs etc.), pornography (which is a feature of Internet, not a bug, as most think), DOS (and DDOS) attacks, e-commerce for those too shy to talk to the pretty/handsome shop assistant etc.

Sixth, running water, both cold and (especially) warm, so everyone has what to wash with their cats once they enter the house through the flap door, and the shower (for humans), which I should have been taking about 1.5 hours now, which means I'm behind my already stressed schedule, making me even more stressed.

Seventh, file sharing networks, which have helped faster development in less developed countries, on the expense of the more developed countries. Ok, piracy is the main issue here, it may be bad, but helped a lot. Thank you! This comment was for real, no kidding included!

I certainly hope I made you laugh a bit or a bit more. Life ain't perfect, so try enjoying the stress!

See you next time with some more technical and boring posts!

BGP: security threats etc. and a bit of Google

2009-09-17T00:30:00.002+03:00

While doing intensive reading on Tuesday (yes, school got me again growing some more white hair), I stumbled upon this quite interesting article Analysis of BGP prefix origins during Google's May 2005 outage (full text available from Carleton). One might be interested, I don't know. Or one might just read it and say to himself/herself: well, that was a funny reason.

Mozilla Firefox, Google search plugin (in the address bar) => remove local redirection (i.e. remove search redirection based on your IP)

2009-03-15T17:12:00.000+02:00

A short note to myself: This post is, first of all, for me, to preserve my brain sanity (joking!) and increase my efficiency when I deal with this situation again. This has been the 4th time when I had to perform a search to solve it, therefore it's time I write it down for future reference.

Situation

The Google search plugin (in the search bar) in Firefox behaves different to what I expect:

The search string is redirected to the local country code Google engine, i.e. .ro, but I prefer the international .com search => I must remove the redirection aka no country redirection

The search result only offers 10 results per page, but I prefer 100.

I noticed that this happens in any one of the following situations:

Firefox is reinstalled

Firefox self updates, e.g. the update to 3.0.7 erased the old google.xml and I had to modify it again.

Therefore, I need a solution.

Solution

First, go to C:\Program Files\Mozilla Firefox\searchplugins

Second, open the google.xml file
This is where all the search bar settings are kept. Once you enter some text in that bar and hit enter, the search is performed based on the settings in that .xml

Perform the following modifications to the file:

Add the following lines:
<Param name="hl" value="en"/>
<Param name="num" value="100"/>
between the tags <Url> and </Url> (you will see similar lines there, but with other parameters)

Delete all the lines of dynamic parameters: start with  and stop before deleting </Url>

Optional: between the tags ShortName, feel free to replace Google with Liviu's Google Search, since I think it's fun.

Save the google.xml file, then restart Firefox. Select the Google search from the address bar (which contains many search options). Insert some string, perform the search. The address bar shall behave as Liviu, i.e. I, likes it to behave.

Enjoy!

Another solution

One can download the search plugin from the Mycroft Project page: click on the Google (No country redirect)

Some useful links:

The search parameters, as explained by Google - who knows, maybe you want to add some more parameters?...

Mustek PowerMust 800 USB: just got broken

2009-03-04T13:50:00.002+02:00

Indeed, my UPS Mustek PowerMust 800 USB just got broken this morning (this is my second UPS that gets broken).

A brief history of my power supplier and the power network
I am unfortunate enough to leave in an area where the power supplier is kind of stupid (although it has changed many names over time) and the network is bad enough (since it hasn't been fixed by any power supplier). The problems last since forever i.e. almost 15 years now.
The power supplier has had many names: Renel, Conel, Electrica etc. Nowadays it's simply called Enel (feel free to read, in Romanian, about the acquisition of Electrica Energie Muntenia by Enel S.p.A)

Technically, the problem is simple: the power goes down every 2-3 months or so, on average; when it comes up, it brings with itself spikes, which hurt the electronics. This had broken me in the last 12 years (chronologically) the following stuff: some 2 HDDs, 1 computer, 1 UPS.

Current situation
Starting some weeks ago (maybe a month or so) the UPS Mustek PowerMust 800 USB that I had (this was my second UPS) started to behave strange: after the power came up, it was beeping continuously.
The power went down this morning too. Since the UPS was beeping continuously when the power came up, I turned it off, then on again. However, all the lights/LEDs (green, yellow, red) were on and the UPS was not providing any power to output whatsoever. I checked the manual and there's no mention of that to troubleshooting - just that red means fault...
Bad news: according to the documents I had since I had acquired it, it's out of warranty too. It had a 2 year warranty and almost 3 years have passed now => a funny detail: the date when I had acquired it was almost exactly 3 years now, minus 12 days...
All in all, the UPS is dead, and now it stays in a nice place waiting for the trip to the trash bin.

So, now got broken the 2nd UPS. Hooray! I have a feeling I should go shopping for another UPS...

[How not to] Design a computer network i.e. [how not to] take care where to place the wires; Bonus: Blogspot failed saving images for scheduled post

2008-11-10T18:56:00.005+02:00

Don't worry, it's not that difficult!
Really, it's quite easy to place the wires of your network in the worst place possible. (Well, come to think about it, the worse one places the wires, the more notorious one's work gets!)

For example, Tuesday, when I had attended one of the courses at the faculty, I wanted to open a window for some fresh air, and what do you know? I bumped into the wires. Let me rephrase: the window bumped into the wires; they were placed up, on the wall, in a very creative and annoying position - check the images below:

It is quite funny, isn't it? Well, even engineers that design networks (and paths for wires) make mistakes, I guess.

Hmm, we have a Bonus Post: Blogspot failed at saving images for this scheduled post

Well, this post was written like 4 days before it's scheduled posting time. I checked it to be ok, I checked that the images were displayed correctly and so on. Then I scheduled it and forgot about it. When it actually got published what do you know? The images were not displayed correctly. I kept the links for original images just for fun - you can see them below... (and, yes, not seeing the images proves my point)

DigiTel (RDS.tel): Call Baring service = restrictionarea apelarii / parolare telefon

2008-11-06T17:09:00.005+02:00

[Updated: 2010, when I noticed RCS&RDS changed the links]

English

Should one live in Romania and have a telephone land line through ~~RDS.tel~~ DigiTel (that's the name of the service offered by the RCS&RDS company), then it might be useful to know how to use the Call Baring Service.

I've searched the ~~RDS.tel site~~ DigiTel (name changed since 2010, probably) for the English version of the pages I am about to refer, but I haven't found them.

The Romanian version for the Call Baring Service - the actual Call Baring Service description for telephone users.

Romanian

Pentru telefon prin ~~RDS.tel~~ DigiTel: restrictionare apeluri (fix, mobil, international) / parolare telefon etc. => informatii utile, solutia etc.

Solutia efectiva cap-coada (comenzile disponibile). Practic, intai faci activarea initiala a serviciului, apoi iti schimbi parola initiala 0000 in ce vrei tu din 4 cifre, apoi iti alegi o restrictie, activezi restrictia si gata; cand vrei sa suni undeva in zona restrictionata, dezactivezi restrictia, suni, apoi reactivezi restrictia. Simplu!
