Lenovo ThinkPad T61

Posted in All, Technology on April 23rd, 2008 · 2 Comments

As I mentioned a few days ago, I was looking for a new laptop. Well, I got one last week, and it’s an amazing Lenovo ThinkPad T61 machine. I am still playing with, learning it, and tweaking it, but I think I’m ready for the post now.

The red button

First things first. There weren’t much of an argument for or against each specific model that I found or that was suggested in the comments to my last post. I needed a machine pretty fast, and I was trying to arrange it in such a way so that I won’t pay for it out of my own pocket (my new employer is kind of cool for this sort of things).

Here are the specs for the tech savvy among you:

  • 15.4″ widescreen form factor
  • 2.1 GHz Intel Core 2 Duo CPU
  • 2 GB RAM
  • 150 GB HDD
  • 3 USB ports
  • some sort of DVD drive
  • 1 Ethernet card, 1 WiFi card, and a whole bunch of other inputs and outputs

Installation process : I did a minimum installation of Fedora 8 from DVD, then copied over my home directory and other important files from my previous laptop, and then installed and upgraded all missing and outdated software. Most of the stuff worked like a charm and didn’t need any sweat.

Issues that I needed time to solve or haven’t solved yet:

  • WiFi switch was off and it took me almost half an hour to figure out. That was probably due to a total lack of sleep though.
  • Fedora 8 has this new pulse audio system, which takes a few steps to setup properly. I had to do this a few times before already, and every time this excellent guide was to the rescue.
  • I still haven’t managed to configure suspend and hibernate functionality. It goes to sleep nicely, but either doesn’t wake up at all, or wakes up with some crucial functionality missing, such as network being totally lost. This is as well the most annoying thing that I miss right now. However, the whole of the Internet suggests that I am doing something wrong and that this stuff should just work.

Impressions:

  • Very fast. This is my first multi-core machine, so I have to get used to it a bit. One thing that I am particularly glad is that it runs Quake 3 at 125 FPS easily. This is the first machine that I have that can do this.
  • Widescreen is the way to go. (And here is the recent Slashdot story to confirm that.) It’s amazing how much difference that little extra space on the side makes. Watching a movie is more pleasurable. Working with images in Gimp is way more convenient. And now I can have a full window browser with a sidebar open, following my Twitter friends. Or an instant messenger window open nearby. Or I can have a really wide console window with plenty of code to scroll through (priceless for vimdiff mode).
  • A little bit heavier than my previous machine. It’s a bit bigger too. But I don’t mind much.
  • A little bit noisier than my previous machine. It feels like the fans are never off. However I suspect there is some great utility software out there to configure and control this.

Overall, it feels like a really nice piece of technology - well built and thoroughly thought out. I need to solve these few remaining issues and it will be a total pleasure to work with.

Yahoo + Microsoft vs. Google et al

Posted in All on February 4th, 2008 · 3 Comments

The big news of last week were of yet another attempt by Microsoft to buy Yahoo.  If you missed all the buzz, Web Worker Daily has a really nice round-up with separate links to facts (read: press releases) and opinions (read: speculations).  If that’s not enough for you, you can always find more with Google, Slashdot, and Digg.

Many online news sources continue to be completely dominated by discussion of Microsoft’s hostile bid to acquire Yahoo! And no wonder: a deal of this magnitude has the potential to touch the lives of pretty much everyone living and working online. It’s a rare web worker indeed who doesn’t use something from one or another of those two companies in their daily lives.

So, first, can it affect me personally?  Yes.  I don’t use any Microsoft/MSN/Live services, but I can’t live without Flickr and del.icio.us, both of which belong to Yahoo now.  Also, I do occasionally use Upcoming.

Now, what do I think about this whole thing?  Well, I think it shows how desperate Microsoft is.  The general trend is towards the web, not the desktop, where they still rule.  Most of their own web services turned out to be pretty lousy.  They want to get online, and they are willing to pay a lot of money to get their fast.  Mostly, of course, this is a war for a place under the advertising sun.

From the Microsoft view point (I think), Yahoo looks to be online.  More than so.  Yahoo is the second most important company online after Google.  And Google is giving Yahoo some rough time.  And Microsoft realizes it clearly, that Google is partially to blame for this whole trend towards the web.  And it also realizes that if it is serious about moving online, it’ll have to compete with Google in one area or another.  So it makes even more sense to acquire Yahoo.  From the Microsoft point of view (again, I think), Yahoo appears to know what they are doing.

And that’s where I see their biggest mistake.  Yahoo is indeed the second most important company on the web after Google.  But it struggles to be there, and it struggles even more to keep Google in sight.  Because it is falling pretty far behind.

A little side note: I think there is a war of concepts between Google and Yahoo. It’s bigger than just advertising space or anything else.

  • Yahoo started off with a directory of links, which was better than many at a time because it was moderated by humans.  Google started off with bringing huge improvements to machine based indexing and searching.  Yahoo:Google - 0:1.
  • Google brought this whole concept of clean user interfaces and simplicity for the end user.  Yahoo stayed and expanded on the old idea of portals, which bring all possible and impossible to the front page of the site.  Yahoo:Google - 0:2.
  • Google made a stake on the brilliance of its people - if the service is properly done, it’ll grow by itself and bring in more users.  Yahoo played it safe, trying to purchase web services that already have momentum.  Yahoo:Google - 1:2.

End of side note.

Overall, I think that this is a bad move on Microsoft part.  If the acquisition will happen, I think, it’ll damage both companies, and, maybe even, drive at least one of them into the ground (eventually, not immediately).  Yahoo, being at the position it is now, needs more flexibility.  The online space is getting more and more competitive.  That’s where you need to move fast.  Yahoo made some really good acquisitions before, and I’d say that they have some sense in this area, but they need more speed with integration of their acquisitions into their backbone.  With Microsoft on board, I’m afraid, everything will get a lot slower.

Also, I think that Yahoo won’t win much from this acquisition.  Surely, some money will come their way, but it’s not always a good thing.  And I don’t think that it’s good in this particular case and at this particular time.   I believe it would do much more good for Yahoo to get smaller, faster, and “hungrier”.  Hunger (think: limited resources) makes one’s mind sharper.  That’s exactly what they need now.  Not more “fat”.

As for Microsoft, I think there strategy should be more directed towards entertainment.  If they really want to buy something, they should buy some entertainment companies.  Those that produce content.  Disney studios maybe? Or some sort of a deal with AOL/Time Warner (they had a few frictions in the past, but they seem to managed to work out a solution together).  With more and easily accessible content they can reinforce end users interest in their Windows desktop, as well as their gaming platform (Xbox thing), and their mobile platform (Windows Mobile).  And, entertainment content by itself is a rather popular thing among the end users, which makes advertising much easier.  And rich advertising too - not just text-based relevant web ads, but audio and video media.

What do you think about all this?

Size does matter

Posted in All on February 4th, 2008 · No Comments

There are plenty of excellent t-shirts around, but once in a while a brilliant one comes up, which makes all the differences.  Here is one at ThinkGeek.com - nanotechnology is huge !

nanotechnology is huge

The moment I saw that phrase appearing in my Google Reader (here is some info about ThinkGeek feeds), I wanted to buy this t-shirt.  Even before I saw the actual t-shirt.  Even despite my total ignorance of nanotechnology.  It’s just so hilarious and true and makes so much sense at the same time!

Cyprus web hosting? Really? Think again …

Posted in All on February 4th, 2008 · 6 Comments

I’m far from honest myself, but at least I don’t charge for my lies. Plenty of people do, however. One of the commonly told lies that I come across rather often these days is the one of Cyprus web hosting. Some companies are telling lies out loud, others are just being overly silent about the truth. But the fact of the matter is that Cyprus web hosting is almost non-existing. There are only just a few companies providing web hosting in Cyprus (PrimeTel and CytaNet, for example), and in most of the cases, their offerings don’t make sense financially. That’s one of the biggest reasons for most of Cyprus web sites being hosted outside of Cyprus, in countries like USA, UK, Germany, and Netherlands.

Still, most of the web design and development companies in Cyprus offer “Cyprus web hosting”. Here is just one example, that I found (ironically, I found it through AdSense block on my own blog) - CyprusWebSpace.com . Here is a partial snapshot of their front page.

CyprusWebSpace.com

If you are using Firefox browser with Flagfox plugin, than you will immediately notice the United States of America flag in the bottom right corner of your browser window. If you don’t have the plugin or don’t trust the information that it provides, or use a totally different browser, here is how you can arrive to the same results:

  1. Go to DomainTools.com
  2. Type cypruswebspace.com in the Whois Lookup form at the top of the page and press the Search button
  3. Scroll down the resulting page to where it says “Server Data”
  4. Find the line with the American flag and a description “Texas - Dallas - Theplanet.com Internet Services Inc”.
  5. Bonus point : look at the map, provided by GeoTool. The area you see is pretty far from Cyprus.

Now, there is always this argument, that the web hosting company runs its own web site on a different server from the one that it uses for its customers. It is a theoretically valid point, but the one I haven’t seen in practice just yet. Most of the web companies offering web hosting in Cyprus only have a single server (usually it is a shared or dedicated server, or a VPS account), which they use for all of their hosting needs.

There is also another argument to this point - what exactly is a Cyprus web hosting? Is it hosting on the web server which physically resides in Cyprus, or is hosting on a web server, which is assigned one of the Cyprus IP addresses? And it is, in fact, an interesting point. There is significant difference between the two. If the server is physically located in Cyprus, then chances are, that it will have a lower latency, meaning that web sites on such a server will appear to respond much faster to visitors who are also in Cyprus. This is what matters for many site owners. On the other hand, Cyprus IP address of the web server might be more important to other site owners, since some search engines use this information in scoring their search results (that is considering, for example, that web sites residing on servers with Cyprus IP addresses are more relevant to Cyprus related queries than web sites residing on other web servers).

Technically, it is quite possible for a web server to be physically located in one country, while carrying the IP address, which belongs to another country. But situations like this, aren’t so common, and that is specifically the reason why search engines (and other tools) utilize the information of IP address location.

So, back to the issue of Cyprus web hosting. How bad is it? Let’s see. Examine the first 10 or so results for each of these queries at Google, using the method above:

Impressed? I am. Results:

  • Companies with web sites physically located in Cyprus: 0 (zero).
  • Companies with web sites hosted on a server with Cyprus IP address: 1 (one).

How do I know about this one company with Cyprus IP address that it doesn’t have the server physically located in Cyprus? Because I am an employee of that company (disclaimer and blah blah blah). And even if I wasn’t, finding this information is rather trivial with any traceroute tool (here is one, for example).

So, keep this stuff in mind before you pay for you Cyprus web hosting next time. Maybe this Cyprus offering is not so Cyprus after all. But then again, maybe you just don’t care…

Legal and educational systems are lagging behind technology

Posted in All on January 14th, 2008 · 3 Comments

I’ve mentioned this many times before and, I guess, I’ll need to mention this ever more - the technological progress of the recent years (the digital world, yes) has left many systems of our society behind.  Educational and legal are the most noticeable.   Here are a few words in the insightful and funny video (originally from the Ted.com - a place of many more insightful videos).  Here is a quote from a recent Boing Boing post showing the state of the legal system:

… pictures of Ford cars cannot be printed. Not just Ford logos, not just Mustang logos, the car -as a whole- is a Ford trademark and its image can’t be reproduced without permission.
