I just updated to Lollipop and I don't like it. I liked all the previous versions of Android and I was very happy with KitKat when I got S5 but this update is all kinds of irritating. The worst part is white background on the notifications and settings and all the phone stuff (phone, contacts, messaging). It was so much better looking and easier on the eyes in black. It's the new Material Design thing that's supposed to give more freedom to designers and bring 3D looks but just looks bad and too bright. Also now screen uses up noticeably more battery. Luckily for me TouchWiz still uses transparent background for App Drawer.

Another deeply annoying thing - the app switcher (Overview) screen. The one when you can look at and close the open apps. You can still use it to close and switch between apps (although I like the old list version better then the new wheel one) but I can no longer go to the home screen by taping the background. It was so much more convenient when I could chose between any of the apps and the main screen in the same place. Why? Why would they remove that?

Samsung Apps updates for Lollipop are also not an improvement. As I mentioned before I used the Health app to track my movements and it just became much less useful. We get the attack of white background again and a lot of less, badly designed information. The screens are much more cluttered and I can no longer check how many steps I did in every 20 minute interval (the graph is smaller and without any scale and you cant move the check point). Also map tracker is pretty much usless now that it's no longer a real map. And a lot of cool statistics got lost too or switched to small pictures instead of something that you can touch, zoom and check at different points. But there whole bunch of stupid, useless awards. YAY! (I'm being sarcastic here).

I could install dark Materials but I would have to root the phone and there are some default things I want to keep so I'm contemplating going back to KitKat. Or I could try different launchers. But the fact that there are already options for darkening available shows I'm not the only one who hates this. As far as I can tell this is a very common complain.

Heartbleed

Everyone is panicking and rightfully so because a really, really awful security bug was discovered. One that lets people get random fragments of data that supposed to be supper secure. It is as bad as everyone says and you can't do anything about it - it has to be fixed on the server sites by providers - and noone knows what data got out - the chunks that were caught were random so maybe they got your credit card numbers they might've contained passwords or even SSL private encryption keys and then you could get everything else. Or just grab so many of those chunks you got everything anyway. That's why they called it Heartbleed.

Basically, an attacker can grab 64K of memory from a server. The attack leaves no trace, and can be done multiple times to grab a different random 64K of memory. This means that anything in memory -- SSL private keys, user keys, anything -- is vulnerable. And you have to assume that it is all compromised. All of it.

"Catastrophic" is the right word. On the scale of 1 to 10, this is an 11.

Half a million sites are vulnerable, including my own. Test your vulnerability here.

The bug has been patched. After you patch your systems, you have to get a new public/private key pair, update your SSL certificate, and then change every password that could potentially be affected.

At this point, the probability is close to one that every target has had its private keys extracted by multiple intelligence agencies. The real question is whether or not someone deliberately inserted this bug into OpenSSL, and has had two years of unfettered access to everything. My guess is accident, but I have no proof.


So to sum up not only you don't really know if you've been compromised (or where) you also cannot do anything about it. Just wait till it gets patched and change all your passwords. Again.

CNet checked the most popular American sites so you'll know which password you can change now.

The funny thing is I learned about it from xkcd (before all the big news outlets and official work emails).

Nobel Prize in Physiology and Medicine was awarded for cell package delivery system - vesicles. Membranes not only separate cells from outside but also create separate compartments inside the cell - most notably nucleus and mitochondria - but there is also long series of something that looks almost like a tube system. Ribosomes stick to part of it and produce proteins. Those proteins end up inside and can be transported inside but the system is long and twisted. Just like it's faster to take a ferry from Gdańsk to Stockholm then drive all around the Baltic Sea it is faster to send a stuff packaged from one compartment to the other. In a vesicle. That transport is highly regulated and used for many different things. That's how cells absorb the food from outside, how they spit out and absorb hormones and how they transport transmembrane proteins. All the countless ours I spent learning how the phagocytosis and endoplasmic reticulum and Golgi apparatus worked I never thought about people who made all those discoveries. It's funny how at some point things like that become basic knowledge of the subject - something you just know.

Prof James Rothman, from Yale University, found proteins embedded in the vesicles which act as the docking mechanism meaning the cargo is released in the correct location. Prof Randy Schekman, from the University of California at Berkeley, discovered the genes which regulated the transport system in yeast. He found that mutations in three genes resulted in a "situation resembling a poorly planned public transport system". Prof Thomas Sudhof, originally from Germany but now at Stanford University in the US, made breakthroughs in how the transport system works in the brain so that neurotransmitters are released at the precise time.

I was disappointed at the journalist disappointment because this is a very important system in the cell and the basic science Nobels are the ones touching the most important subjects.

Nobel Prize in Physics was awarded to people who theorized existence of Higgs boson - Peter Higgs of the University of Edinburgh, UK, and François Englert of the Free University of Brussels, Belgium, have won for developing the theory of how particles acquire mass. The theory is 50 years old but the experimental confirmation is brand new - not even a year old - so the delay in the announcement wasn't that surprising. Ever since few spectacular mistakes at the beginning Nobel committee has preference for waiting long enough to see that no one disproves it and that multiple sources can repeat the results. Still this was a big thing in physics and a long awaited one. And if they didn't do it now there might've not been another chance. Both laureates are in their 80s and Nobels are not given to dead people. I'm most disappointed in comparisons of the problems of finding Peter Higgs for comment during his vacation with the search for Higgs boson.

The Nobel Prize in Chemistry went to theoretical chemists for devising computer simulations to understand chemical processes. Michael Levitt, a British-US citizen of Stanford University; US-Austrian Martin Karplus of Strasbourg University; and US-Israeli Arieh Warshel of the University of Southern California will share the prize. Modelling molecules is becoming a bigger and bigger thing in drug production where new molecular compounds are first tested for possible uses and molecular interactions before spending money on costly synthesis. It can also help predict protein shape and function which helps to understand how cell processes actually work. Those programs use the equations of quantum physics to simulate reactions as closely to reality as possible. It of course requires vast amounts of computing power to describe every electron and atomic nucleus so these detailed models are limited to small molecules with just a few atoms. To model larger molecules we still need to use classical computer models but they do not include descriptions of molecules' energy states, which is vital for simulating reactions. Still they both allow us to sift faster through the possibilities then any RL experiment and concentrate on most plausible possibilities making discoveries faster and drugs (just a little) cheaper.

Due to an error in the ebook version George R. R. Martin - A Feast for Crows was randomly inserted into the text of the novel. Internet as always found a way to make it into meme.

Steven Erikson is going to answer questions about Toll the Hounds on tor.com - he does that after they finish reread of each of the books. I can't wait for The Crippled God. I need to ask about the Princes of Amber and The Little Prince inspirations.

And I learned how to make Vine play on Firefox. The about:config solution fixed my problem (plus of course whitelisting it in Flashblock).

Everyone knows about the Leap Year and most even know why we get the extra day every four years. However in our times of atomic clocks and addiction to extremely precise time measurement we need other corrections. Each day has a little different length and from time to time we have no choice if we want to keep with the planet's rotation we need to adjust the time. It comes in the form of Leap Second - an extra second added to the day at midnight GMT that is the Universal Time everything else refers to.

It happened yesterday and the internet failed. Remember all the panic of Y2K - if you were to young - everyone were afraid the internet servers would fail and the whole world would get disconnected because they only used two digits for year in old OS and keep doing in upgrades so with dates rolling over everything was about to fail. However, this never happened as everyone was talking about it and system got upgraded and the word didn't end. It seems we didn't talk about leap second often enough.

Many of the word's biggest sites - Reddit, 4Chan, LinkedIn, The Pirate Bay, Yelp, Meetup, Gawker, Mozzilla, Foursquare - experienced problems and shut down when leap second struck. It seems that all that was affected was either based on Debian Squeeze Linux servers or running something based on Java/Cassandra. Luckily, the world didn't end from this either. Maybe because, unlike so many others, Google was prepared and didn't fail.

Let's hope we'll do better with next one.

Today is 100 anniversary of Alan Turing's birth. Now, 100 years after he was born he's a hero. He's lauded as a man who broke the Enigma code (although this was not something he did alone and, as a Pole, I cannot not mention it was first broken by Polish cryptographers - Turing made a machine broke the second generation Enigmas). He is considered the father of computer programming and everyone who dip into it learn his programming basics. The Turing machine concept ies what made computers as we know them today possible. He is known to science fiction fans because of the Turing test (the basic test for Artificial Intelligence when it's considered to be AI if a human is unable to tell the difference between human and AI in a blind test conversation). He did all this and he could've done so much more - the whole computer age before him. However his career was cut short what it was discovered he was homosexual and he was forced to choose between prison and chemical castration and eventually pressure was to much and he committed suicide (although some believe it might've been accident). I remember the first time I heard about it and thought about how unfair, stupid and what and incredible waste it was. British government finally officially apologised for this in 2009 (at least it took them less the Catholic Church to apologise to Galileo).

Now Alan Turing is celebrated - io9 has a great collection of articles and resources about him and Google made a great puzzle Doodle for him (if it's still 23 June where you are just go to your local main google page - if not you can watch one version being solved). I played it first last night after the midnight and again today (it was different every time). It helps if you know the programming logic rules he invented but you can figure it out even without it. Have fun with Alan Turing. You do it using his ideas everyday.

I almost missed that Linux is 20 years old today. The first announcment was published on minix newsgroup by Linus Torvalds on 25th of August, 1991. The operating system that's maybe not that popular for desktop use but which versatility and superior safety features means it secretly runs the world (or at least the internet). It's the OS of supercomputers and servers. Governments and schools like it because it's free and can be customised by anyone (or at least someone can customise it for you). It is the flagship for GNU and Creative Commons movements. It also shows that people can and do work for projects they are not paid for and can create communities to improve what they like instead of destroying public property. This is the thinking that spawned wikipedia and countless other projects that changed our life (it doesn't mean lack of moderation but that's the difference between democracy and anarchy). Most people who are not into programming or not part of academia don't have much contact or even know about it. or rather didn't have contact with it as the rise of android system based smartphones and tablets means you may carry it with you every day. It may not be a true Linux (and not truly as free modifiable without binaries but much closer then any other OS) but what really is? The versions are may and it is like life - constantly evolving.


Windows is ubiquitous and OS X is pretty but it's Linux that really makes world go round. And you don't even realise how many of it features have been incorporated into the bigger players (Macs even run its version by default). It's one of those things that makes me feel better about human race. Here's for next 20 years for the penguin.





I'll be celebrating 20 years of Linux with The Linux Foundation!

It suddenly got warm. After 2 months of often bitter cold and sometimes snow summer struck. Just last Wednesday it was barley above 0 and drizzle was coming from the sky the whole day. We were celebrating my friends birthday and the four of us Polish girls agreed this was exactly  like the worst November weather back home. Then it started to get warmer day by day. Friday was nice. Yesterday was warm. Today was hot. It was 17C in the shade and 25 in the sun. Yesterday I walked just in a long sleeved blouse and I though it was nice. Today I went for a walk in a short sleeve t-shirt and summer shoes and I was overheating. I wished I've chosen to wear shorts like so many other people on the streets.

As much as I enjoyed today's weather, Spring has certain disadvantages for me. I clearly saw today first signs of new season. The buds are starting to sprout and my symptoms clearly tell me something already started to pollinate. My nose is starting to run and my eyes are getting puffy in the morning and it reminded me that I need to start taking my ant-asthma meds. I was not prepared on starting them already - I keep forgetting Spring comes earlier here.The problems with highly evolved attack system that has nothing to fight - it finds enemies even were there are none.

BTW Do you want to see evolution in real time? Use the BoxCar 2D - Genetic Algorithm Car Evolution Using Box2D Physics and in a little while you can get a working car from some triangles and circles. At the beginnings the shapes are pretty random but they are selected for best functionality for riding the 2D landscape and they get better and more efficient with each generation. Just let it go for few hours. (Artificial) Natural Selection FTW.

I dislike the HP printers. It's not that they are bad. In fact my problem isn't the printers themselves. It's the software. It's big, clunky and it makes the installation of a printer into a chore.

I just spent today trying to make the printer work properly. It finally got an IP number and was connected to the network. So all I needed to do was to get it working. There was an installation CD with the printer but it didn't have the Windows 7 driver. That's because there is no Windows 7 driver for the Color LaserJet CP 2025dn printer. The instruction and the site say one needs to download and install the Universal Driver. This is untrue. I mean sure it does make the printer work and even print in duplex but not in colour.

To make the printer print in colour you need completely different driver. You need the Color LaserJet CP2020 Series PCL6 driver. But then the printer looses the ability to print in duplex. It's because the drivers installs with option for duplex set as Not Installed. One needs to go to Printer properties then to the Device Settings and manually change the Duplex to Installed.

Then I went back to another building were the printer just like this was in use for about a year. I was told when I arrived it was without duplex. This was untrue of course. I wonder how many people out there I convinced they got the version without duplex even though it's untrue. All those trees.

In my previous work we had XP on computers. The installation disks for that HP printers should be working just fine. The installation always crashed couple of times before it went through. It was better to allow Windows to just find the driver. Especially since once again it sometimes installed without duplex option. More randomly in this case.

I don't know who writes those driver installation programs but if installing your printer needs an someone who is tech savvy to make it work properly then there is some very serious problem with your software. This is something that installation software should be able to detect.  You write for people whose ability ends at putting the right disk in and clicking through setup program. If making the device work involves wading through misinformation and obscure options it's not user friendly. It's a puzzle to solve. And most people won't even be able to do it.

If I'd ever decide to buy printer for myself it won't be HP.

I haven't used internet explorer for years. I started with Netscape actually. I then used the IE for a little while but I returned to Netscape soon as I wanted to have a browser for my own. My parents preferred IE then as it had Polish version. But then IE got progerssively worse and worse so my parents switched to Firefox and we all mostly forgot IE existed.

Every time in all this years some I was forced to use Internet Explorer it drove me mad. There wasn't a program that could make me want to throw the computer out of the window as fast as IE could. I think the 6 or 7 version was the worst. I usually give up in couple of minutes and go back to the nice and easy world of Mozilla products. I tried Opera and Chrome but some of my favourite pages didn't work as they should. I tried IE 8 and it was better but still annoying.

Why I wrote all this? The beta version of IE 9 premiered yesterday. It's should be faster and better with graphics, video and java.  In other words pretty. And I'm, as you all should already know, unable to resist new and shiny tech. So I just had to try it.

It broke on the first try. What was even more annoying it kept on restarting itself and crashing again. I had to kill it. It only took it a minute to get me annoyed. But it's beta version so it can be excused. I got it working finally.

It looks pretty Chrome like. And html5 is shiny. But I think I'll wait till the alpha version. And see what other browsers will do. I don't trust IE to be user friendly. And there are too many features in FF I love to much to give up. I can't live without tabs inheriting history.
