The "page flash" on the Kindle 4 - the sudden turning of all the pixels black and then white, before the page is displayed - occurs every 6 page turns. It seems to be necessary because a certain amount of 'dirt' accumulates inbetween - bold letters (and also normal text) seem to leave traces pixels around the edges of the letters after they have been wiped after a page turn. The 'flash' wipes these pixels out and makes the page look crisp again. I don't know if this is a flaw in the driver software, or a shortcoming in the e-ink display itself (that leaves the traces).

I ditched eclipse for C when I found QT Creator. But I still kept it around for my python code, but it got annoying. Then I found PyCharm. I like it. Bye bye eclipse.

Use numpy.set_printoptions . One of the things I like most about pylab (and numpy) is this flexibility, especially the summarization feature, which, when the array is very large, prints ellipses (...) instead of clobbering you with lines and lines of output. I like to set the threshold low (default is 1000) and I do this with pylab.set_printoptions(threshold=10)

Sample C code is at plx2csv , rather striaghtofrward reading of the plexon binary file Needed to load the data into Python, so looked at Boost.Python and pybindgen , but then decided that pickling the data from the c code and loading it into python scripts would be fine and so used The PicklingTools library.

From discussions on stack overflow we have: ++i does not expect to return a value while i++ might need to return a value. A modern compiler, for simple data types (i.e. integer) will treat the two the same if the context is right e.g. in a for loop For an object (e.g. an interator), however, ++i will be faster than i++ because a compiler cannot optimize away the creation of a temporary object for i++

Use latexdiff e.g. latexdiff ../v01/Complete/main_v02.tex main_v02.tex > diff.tex Then compile diff.tex (and don't forget to run bibtex, though new citations don't show up as changes)

From the first answer here : This is due to xcode install messing with /usr/share/terminfo The default terminal is xterm-256color which is removed from /usr/share/terminfo/78 If you have a TimeMachine backup, use that to restore /usr/share/terminfo.  If you don't, use the file provided here .

QFileInfo.created() on POSIX systems (like Mac OS X) returns the last modified time . This is annoying because on Mac OS X you know the system (e.g. finder) has access to the actual creation time. Turns out that BSD systems (like Mac OS X) have an extension to sys/stat.h that contains the file creation time. The recipe, then is (shown using the QT framework): #include <QtCore> #include <sys/stat.h> int main(int argc, char *argv[]) { QString fname("/Users/kghose/Sandbox/ChhobiTest/2005/2005_07_10/MVI_0693.AVI"); QDateTime thedatetime; struct stat64 the_time; stat64(fname.toStdString().c_str(), &the_time); thedatetime.setTime_t(the_time.st_birthtimespec.tv_sec); qDebug() << thedatetime; }

MenuMeters is an opensource program that does, very colorfully, what iStat does and works on Lion. The appearance is not as slick as iStat, but it is very configurable.

I don't deal with political topics here. But there were some thoughts I had on this fad going around on income inequality. If you take a look at this report by the economist the claim is that while the income disparity between 99% of the people in the US hasn't changed much that between the 99% and the 1% has changed a lot. I can see in my mind's eye some person or persons with a definite political agenda sitting at their software and moving a slider control. They first split the population 50/50 and grunt with dissatisfaction. They move it to 25/75. Still not so good. Then they get all excited and move it all the way to 1/99. Yay! Look at THAT income disparity. I have a few concerns about this graph. Perhaps someone can enlighten me? If I took the top 1% of a distribution MOST measures I would make using that 1% would be biased in some extreme way. There is no way I could stop that, because I took an extreme part of the population to start with. I'm taking a f...

Open image in Preview.app, "print" and save as pdf Open pdf you want to add to Open the pages pane Drag and drop the image pdf you just created into the pages pane (in whatever sequence you want it) Preview.app will show the pdf to be "edited" Save the pdf You can directly drag and drop the image file from the Finder into the pages pane. This will, however, add a white border round the image.

iTunes is annoying because clicking "+" (maximize) moves it to mini-player mode. Holding down "option" when clicking "+" will make it work like mazimize

Holding down "shift" when you press "reply" or "forward" causes emails to be composed in HTML in thunderbird. Probably the most useful tip I have seen.

New HDD was cut into two partitions and win xp was installed on one. Ubuntu was installed off a USB stick "Install alongside Win XP" was chosen. This correctly used the empty (unformatted) partition for Linux, with appropriate swap space choice. Ssh needs to be installed - can be installed through the package manager. I used a metapackage to install both client and server. The changes took effect immediately (no restart or manually starting server).

Most impressed by migration: just needed to hook up my time machine disk to the new machine in in 2 hours my WHOLE computer was transplanted onto the new mac, including applications and frameworks. When I went to run eclipse (Helios) I was asked to install java runtime, which the OS installer found and installed by itself. The fast login switching, not so useful for single user laptops and also takes up menubar space with your name can be removed from system preferences ( here ). Spaces threw me: from here , we see that the way to add new spaces is to go into misson control (middle click) and then move the pointer to the top right hand corner to add a new desktop. To use the existing time machine backup (so you keep your history etc), however, all the files seem to be copied over afresh - so you get a new snapshot which uses a lot of space - the first new backup is not incremental. The screen looks different - the colors are brighter - but perhaps my old macbook's lcd was jus...

One of the few games I ever bought when it came out (thus at full price. That's how much I wanted it) Tossing a cardboard box at armed NPCs now leads the bastards to gun you down mercilessly, rather than simply yell at and berate you like they used to do in DE You can drag a body through the vents. Immersive side-story items Improved dialog system much like RPG You can sell stuff you don't need for cash - so I sell all the lethal weapons, which I don't use.  A LOT of attention has been paid to detail and atmosphere, one of the few games I would recommend to get at full price to reward the creators. If you liked Deus Ex, you will definitely enjoy this one, which has update graphics and some enjoyable new augs.

The person at the Lufthansa counter accepted the combo EAD/AP card The immigration official at Indian customs examined the card closely, looked at my expired H1-B visa stamp, asked me if they would let me in with this card (I said yes) and then let me pass At Frankfurt, I was asked if I have a visa, I said "Yes, a German visa" (I had a one year multiple entry German visa). She did not flip through the passport to actually find the visa, she just let me through after looking at the front page. Current regulations state you need a transit visa if you are on AP and are not from one of the visa waiver countries. At US immigration I was asked to fill out the white I-94 card and sent to secondary inspection At secondary inspection the lady asked a few questions about my specialization and then stamped the I-94 card as "DA/AOS" and let me through. She also "Cancelled Without Prejudice" my expired H1-B visa stamp I did not have to show any documents other tha...

The endfloat package is kind of fancy but the problem I faced with it is that I was renumbering figures in the middle of the document and the latex referencing algorithms were handling it fine, but when the figures appeared at the end of the document their numbering was screwed up. There is an easy way, however, to push the figures to the end of the document as I wanted. From some hints here about how LaTeX decides whether there is enough space on a page to put in a figure \renewcommand{\textfraction}{1.0} \renewcommand{\floatpagefraction}{0.9} in the preamble does the trick, by fooling LaTeX into deciding there is NEVER enough space to put figures on a page until it is all out of text and has to just dump the figures as best as it can, one to a page.

Never bothered to figure out what this xetex thing was. Turns out it can handle unicode. For texmaker just replace pdflatex command with xelatex and use a unicode aware font (e.g. \usepackage{helvet}) and things should work

LyX has a really nice online math type setting system. I have a math heavy document that I wanted to type up using LyX. Pretty soon I had the classic problem of any feedback system with feedback delay - oscillations. I would type something, it would take about a quarter of a second to update, I would move my mouse to click on a formula, it would take a quarter of a second to change state and by that time I would have clicked twice, the document would have scrolled, and the formula would change state again, because I had clicked somewhere else. Welp. Its back to good old latex and text editors for me. I don't mind the write-compile cycle. LyX is good for text documents, but for math, at least on mac, it is so sluggish, it is more annoying than anything. UPDATE: I have found texmaker to be a very nice IDE on mac.

Grumble, grumble. MathML on Firefox on mac was going great guns, until I find that \mathcal{N} gives me garbage (but \mathcal{M} looks fine). I see from this bugreport , that this is an issue with the STIX fonts.

Problem: I'm using bottle for a desktop browser based app. I needed to call a page view from an action. The page view normally gets some parameters encoded in a GET request. Solution: The GET request can be faked by doing: request.GET.append(key, value) Since request.GET is just a dictionary.

Sometimes merge/branch will refuse to work, saying your resource is out of synch. Do an 'update' and then a 'commit'. After a rename or move + commit, subclipse will say resource is out of synch with the filesystem, just refresh,commit and continue pydev explorer does not show the .* project files. These need to be added to svnignore (or committed if you wish). Use the eclipse navigator to see these file switching a branch to be the trunk is annoying in svn: basically you have to move the folder over - so the current trunk has to be moved (possibly under branches with a new name) and the branch you want has to be moved over and renamed as trunk

I like to compose my equations in LaTeX. I find it a lot faster than the click interface of MS Word's own equation editor. I type up my notes in a LaTeX format so I already have the equations and its a terrible inefficient duplication of work to hunt-n-click them into ms word. One solution is to print a pdf of all the equations, and then use the select tool in preview to copy the equation and then paste it into the word document. The advantage in mac os x is that the copy is in vector format, which means that the inserted equation does not behave as an image - becoming pixellated at the worst moments, but rather scales gracefully. That's gonna save me some time.

Ok, this is the first thing in Python I have found to be annoying and nonintuitive. When you pickle a class object you need to make sure that the module for the class is explicitly in scope and imported. I kept banging my head against this problem and only understood it after looking at this guy's blog . When you pickle a class object included in the pickle file is a coded import statement telling the interpreter which module to import to look for the definition of the class. This leads to the following gotcha: The following code will define a class, instantiate it and pickle it without problems #File class_a.py import cPickle class A: def __init__(self): self.x = 22 if __name__ == "__main__": a = A() cPickle.dump(a, open('obja.pkl','wb'), protocol=-1) print cPickle.dumps(a, protocol=0) Notice the stringification of the class : it begins with i__main__ Now, we run the following code to load the object from the pickle: import cPickl...

Go to the application's bundle (e.g. X11.app) and open the bundle contents. Navigate to Info.plist, open it with a text editor or plist editor. Add or change an item with the key "NSUIElement" and set its value to "1" (type = string). On relaunch of the application, its icon will not appear in the dock. This is usefull for apps like X11 which are servers and should be running in the background.

Type in the url of the icon file and load the image.

I've been happily using pysqlite to access my sqlite databases from python. Suddenly, I find, however, that there is a query that runs much, much slower in pysqlite than in apsw and the sqlite shell.

From a blog post here , I found out about Paperpile . I downloaded and ran it, but haven't used it, since I use my own, but Paperpile has  a nice clean look. Though there is GPL code of Paperpile on github , the main website seems to indicate the author has hopes of commercializing (and closing the source) to Paperpile if things look successful.

adminer is a nice php based sqlite manager. I prefer the firefox plugin "sqlite manager" but it currently has a strange issue with FF5 that basically makes it unworkable, so I was looking for an alternative to tide me over. I really don't want apache running all the time on my computer and don't want people browsing to my computer, so what I needed to do was: Download the adminer php script into /Library/WebServer/Documents/ Change /etc/apache2/httpd.conf to allow running of php scripts (uncomment the line that begins: LoadModule php5_module Start the apache server: sudo apachectl -k start Operate the script by going to localhost Stop the server: sudo apachectl -k stop

Perhaps my long search for a convenient way to code database frontends that work locally ("desktop app") but leverage the power of a browser as a GUI has come to a successful point. This point involves: Python (Naturally) Bottle - a "microframework" py2app - py2exe for windows The only tricks making Bottle and  py2app work well together were You need to explicitly list the template files when calling py2app, otherwise they don't get included in Resources I had to add a url route (which I called /quit) that called os._exit() to shut down the server (otherwise done using CTRL-C). just exit() and even SIGINT did not work. This is a bit extreme, but I think safe in this usage. I was happy to see that the created app used the Resources directory as the working directory and the packager put all the files in this directory making things very transparent and worry free.

From the HTML standards . Use POST when the operation has lasting changes on the world, like a database modification.

So, there are artists who paint patterns on walls that turn into a recognizable figure if you are standing at the right perspective (e.g. here ). One easy way to generate these patterns is to set up a projector with a slide of the pattern that you want projecting from the vantage point you want, and then paint according to the projected pattern.

The D40 is an awesome camera, especially at the price I bought it ($375 with kit lens - but refurbished). It's years out of production now and has been superseded, but it does fine for my casual needs. The only two gripes I have about it, in order of importance are: Auto white balance is sucky for incandescent lighting. So I always switch from auto to preset when I shoot indoors. Only one func button makes it awkward. I have to pick between select ISO and select WB for that button. I think select WB wins out, but it would be nice to have dedicated buttons for that.

This lens is very, very good. I had read on boards from people who would never take this lens off the camera. I find that most of my shooting is done with this lens. The kit lens that came with the D40 (The Nikon 18-55 mm) is very good, but the 35mm's 1.8 aperture is great.

Wanted to have an IM for Bangla on the Mac Didn't find any online Found this tutorial from Apple on how to make an IM Only problem is that the system does not seem to support the generation of conjunctions of vowel modifiers. This means that each and every conjunction and consonant+vowel combination must be present in the file: i.e. if we want to write কৌ (kou) we have to set kou = কৌ in the file: we can't build a rule. So this file must have all the possible combinations, like কু  কূ etc. etc. This is tedious to do by hand. I'm working on a small script to do these mix-n-matches and print out a input method file based on the rules I developed for lekho (see I knew that effort would come in useful some day!)

Sparse bundles , like read/write disk images, can be encrypted Create a sparse bundle through the disk utility The sparse bundle's size on disk corresponds to its content size (which I like, but you may not like that it gives away some information about its insides) The change password function of Disk Utility (Images->Change Password) does not work through the GUI (the sparse bundle is greyed out and can not be selected). Use the command line instead: hdiutil chpass /path/to/Encrypted.sparsebundle/ The sparse bundle is supposed to be easier on Time Machine and other backups, because it is not one monolithic structure. Resizing the sparse bundle needs to also be done through the command line (GUI greyed out) and is done using hdiutil resize -size 1.5g /path/to/bundle Where 1.5g is the new size. It will ask you for the password.

GRAMPS is a nice, open source (GPLd) program written in python that allows you to build up a database of family relationships, from which you can make genealogy trees GRAMPS runs on mac os, and they say it should run on windows and linux too It is very intuitive and easy to use I miss the ability to see descendant family trees with siblings etc ( like this ), but perhaps there is a trick to do that.

Problem: Mac OS X Finder doesn't show the little thumbnails properly (where it used to before). For example, it will show thumbnails for .txt or .html files, but will only show a generic JPEG thumbnail for .jpg files Solution: (From here ) Go to (your home) > Library > Preferences folder, delete the com.apple.finder.plist file and the com.apple.sidebarlists.plist file if it exists, and then restart Finder from the force quit menu.
