I've been trying Microsoft Vista for the last couple months, on the post-thief-bought EasyNote BG45-P-006. Contrary to what you probably keep hearing from colleagues, Vista works relatively good for me. Am I sold for some screen blings? Definitely not. Would I give up my GNOME desktop? Definitely not. Here is the pro:

• Good support for my hardware.
• Fair enough power management.
• Reliable suspend and resume.
• Very, very good fonts and font rendering. I mean, close-to-Apple-good, but not there yet.
• Quick user switching.

And here is what you'll love most, the con list:

• Slow startup. It takes like ages to get a usable desktop.
• Immature support for wireless networks. Actually, wired networks are not so good at all. I keep myself doing ipconfig /release and ipconfig /renew all the time.
• Too many questions. Security doesn't mean ask user about everything.
• Enormous, gigantic memory usage. Boy, a decent default desktop uses just about 1 GB memory. I've got 2, so this beast uses about half of it for itself.
• It's messing around with my hard drive all the time. Disk light keeps blinking every couple seconds even if I have nothing running. This prevents disk from entering standby to save more power.
• I like the new Start menu layout but searching the menu is just too slow.
• There's no use for Sidebar on my desktop.

For your pleasure, here's what my usual work session looks like:

• Eclipse
• Firefox
• Thunderbird
• PuTTY, and Pageant.
• Cygwin
• Vim
• OpenOffice.org
• Last.fm Client
• Xming
• Pidgin
• Skype
• Google Talk

Most of what you see in the list is open source, or free software. I also have an Ubuntu Intrepid Ibex installation on the same device but I pushed myself to bear with Vista stupidities for a while. I think I'll go back as soon as they fix Compiz's multi-head support. For my single-headed desktop needs at work, I just use Ubuntu.

Mankind invested a lot in Internal Combustion Engines, possibly more so than they deserve. Watch this:

• They're inefficient. Even when turbocharged, an average ICE will achieve about 25% efficiency when converting fuel to kinetic energy.
• They're noisy. Fuel burns, potential energy of the fuel is converted to kinetic energy but you can only utilize 25% at best. So where does the rest of the energy go? Simple, some of it becomes noise.
• They heat up. Well, some more of the wasted energy is also released as heat.
• They pollute. In many different ways. An ICE can't possibly burn all of the fuel, that would require enormous amounts of oxygen and air, so they only burn it partially. A good wealth of fuel pass out (either intact or as a result of many chemical reactions) from the exhaust, even when turbocharged. Released waste is hazardous to plants, animals and man.
• There's more crap. An ICE requires quite a bit more of complicated machinery to be useful on small cars: The Transmission System. Quite a lot of the kinetic energy generated by the engine after burning fuel is once again lost somewhere in this machinery.
• They are heavy. ICE and the machinery it comes attached with has to be made of strong and heavy metal like steel to survive the load. Lets face it: a 4-people car, 100kg for each person and 50kg for the luggage makes 450kg. But an average car weight today is about 1200kg. This is, in my humble opinion, ridiculous at best.
• They are dangerous, because you carry very flammable fuel with you. Well, diesels are slightly less dangerous, I must admit.
• Initial, operational and maintenance costs are incredible. These giant waste-generating monsters require that several parts changed with new ones frequently.

So it looks like mankind found another way of screwing each other and himself, not long ago. Boy, compare that to the old way now. Harnessed horses are efficient, relatively fast, comfortable, quiet and environment friendly. Even the waste is utilized somewhere in agriculture industry.

Yes, I drove the car this morning to come to work. And yes again, it has an internal combustion engine and a total weight of about 1200kg.

Soon I will write about the realistic alternatives.

That's what I have become. Speaking of energy efficiency and cars I'd like to post my personal quick-and-dirty efficiency-focused market review about cars due to popular demand.

We own a 2007 Renault Megane II 1.5 DCI Expression 80hp. We did some 20000 kilometers in the last 6 months and I've collected some statistics about efficiency. I'm not really happy to drive an internal combustion engine but this ~1200kg device proved to be somewhat efficient:

More than 1250 kilometers per 60-litres-tank (and still going, will probably do about 1300) is not so bad if you're patient enough to cruise around 100km/h. More than half of this was done on city traffic, which means the engine consumes 4.3lt/100kms and according to Renault its CO₂ emission is something like 117g/km and 91% of the mass can be recycled. Interior quality is not so good compared to a BMW, but it has relatively good price/performance ratio.

Small Common-rail Diesel engines are relatively efficient, but Renault-Nissan is after something better: Project Better Place. Apparently Renault will supply 100% electric cars and help build the infrastructure in Israel and Denmark to support usage of electric cars. The project is supported by the government in a usual way: reduced taxes.

If you're interested in hybrids, which I'm not really into: there's Honda Civic Sedan Hybrid. And for god's sake, please, no SUVs.

We use public transport when possible, I'll buy a bike for the summer, and we just walk when time permits. Safe and healthy, highly recommended. Human body is 9^th Symphony of the nature, the most efficient food-to-you-know-what converter ever.

Enjoy.

It looks like Google did it again, now they support presentation documents (those created by Microsoft Powerpoint or OpenOffice.org Impress) on Google Docs.

Note to myself, to investigate it further. I want this so badly. I hate wires as much as Nikola Tesla hated them, more than a century ago.

I'm not really sure if it's a coincidence, Marin Soljačić, also a Croatian from Zagreb, at Physics Department of MIT since 2005 is working on this subject. Hmm.

Gezegen'de bazı arkadaşlar ~okaratas ile eğleniyorlardı, insanları pek keyifli görünce eğlenceliklerden bir tane de ben ekleyeyim dedim. Eskiden bir Güzin ablamız vardı, insanlar dertlerini ona yazarlardı, o da (Erdener abi gibi değil tabii ama) elinden geldiğince mantıklı yanıt vermeye çalışırdı. Şimdi kendisi yokmuş, yerine kızı varmış ama pek tutmuyormuş galiba. Başlıktaki sorunun şekli nasıl olduysa Güzin ablayı anımsattı bana. Yeniyetmeler için Güzin abla yaklaşık şöyle sorularla muhatap olurdu:

Sevgili Güzin abla,

Geçen yaz ailecek köye gittik. Köyde yıllardır görmediğim amcamın oğluyla çimenlerde yuvarlandık. Ama üstümüzde elbiseler vardı. Acaba hamile miyim?

Seni ilgiyle okuyorum, ne olur cevap yaz.

Güzin abla ~okaratas ve bu hanım kızımız gibilerine ne dese iyidir bilemedim. Zaten dese kendine dert, demese bize dert...

Üstünüze afiyet ben geçen hafta cüzdanımı (ve dolayısıyla muhtelif kimlikleri ve kartları) kaybetmiş idim. Kartlar kolay da kimlikler dertli biraz, yeni çıkarılacak ehliyetimi almak üzere ofisten erken çıkıp otobüse bindim. Mecidiyeköy civarında dizüstü bilgisayarımı açıp çıkarken yarım bıraktığım ve yürürken aklıma takılan bir hadiseye bakma gereği duydum, duymaz olaydım. NetworkManager şöyle birşey gösterdi bana:

Efendim derler ki askerlikte erlere ot yoldurdukları olurmuş eskiden, boş kalınca düşünüyorlar, düşünen adam tehlikelidir diye. İnsan otobüste, otobüs trafikte olunca boş kalıyor. Düşündüm, aklıma (sıradaki şarkıyı Alper Oğuz'a armağan ediyorum) Show TV'de çalıştığım kısa süre içerisinde öğrendiğim ama nasıl olduysa unuttuğum bir hadise geldi.

İstanbul'da yaşayanlar bilir, bu koca şehirde yayın yapan onlarca televizyon kanalının dev antenleri süsler Çamlıca tepesini. İşte oradaki anten kulelerinin hemen altında çok sayıda adam çalışır (vallahi ben hiç kadın görmedim). Bu adamlar olası bir arıza durumunda oradaki teçhizata anında müdahale yapmak üzere oradadırlar, bildiğim kadarıyla her yayın kuruluşunun 3 vardiya ve ikişerli gruplar halinde bulundurduğu personeli vardır. Wikipedia'daki Radio Propagation makalesinden alıntı:

In free space, all electromagnetic waves (radio, light, X-rays, etc) obey the inverse-square law which states that an electromagnetic wave's strength is proportional to 1/r² where r is the distance (range) from the source. Doubling the distance from a transmitter means the signal strength is reduced to nearly one quarter.

Buna göre antenlerin hemen altında çalışan bu adamlar antenden yayılan radyasyonun en kuvvetlisine maruz kalıyorlar; ve orada çalışan birinden öğrendiğim kadarıyla hiçbirinin erkek çocuğu yok.

Tabii bizim kablosuz bağlantı noktalarının çıkış gücü 100mW ile sınırlıdır ama yukarıdaki manzara etraftaki GSM istasyonlarını da ekleyince korkutmuyor değil hani. Ne dersin Güzin abla, olacak mı erkek çocuğumuz?
