A quick bunch of fresh thoughts on Ipad (I had no experience with Iphone):That the machine you'd like to take with you to the toilet or to the kitchen. Laptops are just too big.Yes, one doesn't know where to tap/click. I didn't know where to tap to buy app on Appstore!I'm missing the back button very much. Maybe that will go away when multitasking comes in.The back button in Safari is very far

Whatever you are using: a blog, a portal, a forum or microblogging service, search works on current set of documents.If I remove my last blog post, I expect a search to omit it in the search results. Search ought to include only the most recent state of documents. But what if you can navigate through the history of document? What should appear in the search? We are used to see only the most

It's time to undust this blog a bit. Here is the list of my recent posts on LShift blog, with a word of comment:Introducing RabbitMQ-Status plugin. Well, this plugin is intended to help sysadmins understand what's happening inside Rabbit. Stupid, simple, robust: the way sysadmin stuff should be.Python Quirks. My rant about Python language.

I just spent more than an hour trying to buy a thing from Ebay. I'm really pissed off. In short words: Fuck you ebay.So the story goes like that:I found an itemI clicked "buy it now". So far, so good.They want me to register on ebay. I don't want yet-another-password and yet-another-stupid-user-name. Why the hell do I need that for? I'm trying to buy a thing, not an insurance.

For some time I'm trying to hack together a prototype of real-time-full-text-search-engine (RTFTSE!). I used a memcached-binary protocol as a communication protocol between backends and storage-nodes.This is a pretty nice protocol and in fact there are strong reasons not to use ascii memcache protocol.

This article about EvServer doesn't really show it as an innovative piece of software. I hope that future articles will.It seems that the most important thing in this post is a blinking exclamation mark.BTW, ItBlog seems to be dead. For historical reasons I placed my old posts from that blog here, here and here.

Few days ago I committed a blog post about Twitter search.As a matter of fact, I'm not sure what is the solution to the question I asked there. On the other hand I presented some interesting (at least for me) numbers.While writing this stuff I learned a lot and maybe this blog post will be a motivation for someone to actually create such a perfect system.I'm still thinking about the persistence

Few times I was pissed off by this screen:It means that I haven't activated Vista on time and Microsoft stopped liking me. The problem is that at least two times I was caught by this screen when I haven't got access to the net. I had password to WiFi, but haven't entered it yet. When Vista is blocked you don't have access to any networking settings so the password is useless. Yet another time,
