• Replacing latex with unicode symbols

  - by Elazar Leibovich

  Often, during a conversation or an email, or at a forum, I would like to type some math, but I don't need full equation support. Unicode symbols should suffice. What I need is an easy way to type math related unicode symbols. Since I already know latex, it makes sense to use the latex symbol mnemonics to type the math symbols. What I currently…

• hardware for pushing buttons

  - by Elazar Leibovich

  Many times I want my computer to interface old hardware. Such as radio, light switch, etc. This mostly involves pushing pressing and moving various buttons and switches. I don't want to buy new hardware I want my computer to interface the old hardware I already have. I thought about it and reached to the conclusion that what I need is a…

• Bandwidth preserving browsing mode

  - by Elazar Leibovich

  I'm looking at some methods to browse the web, in situations where bandwidth is scarce (such as, flaky wifi connection, or mobile phone internet provider who overcharges the bandwidth). One thing that would save alot of bandwidth is not downloading images while browsing. This approach has two main drawbacks Sometimes a site's layout…

• Easily typing unicode letters to a HTML form

  - by Elazar Leibovich

  Is there a program or a key map that allows me to easily type mathematcial symbols and unicode letters such as these symbols in a web form? Maybe a keyboard mapping? An assitant program? (What I'm doing now is, copy-pasting relevant symbols, which is far from convenient...)

• What is the impact of leaving a laptop in "sleep" mode (while on battery power)?

  - by Elazar Leibovich

  How much battery would leaving my laptop at "sleep" mode consume? is the consumption low enough so that it would be safe to leave the laptop sleeping at nights regularily and using it tommorow? What's the recommended period of time for which I should not turn it off, but let it sleep. (for example, if I'll use the computer in a minute…

• Open source alternative for "Intellitrace"

  - by Elazar Leibovich

  Microsoft has recently announced "Intellitrace", a killer feature for VS2010 IMHO. Basically it records all the instructions the program ran, and allows you to easily look through the execution log. Is there a similar feature for open source tools? Specifically such a feature for Java with Eclipse integration would be a nice thing to…

• Why scala's TreeSet returns SortedSet

  - by Elazar Leibovich

  Is there a reason that the object TreeSet.apply method returns SortedSet and not TreeSet? The following code won't compile in scala 2.7 val t:TreeSet[Int] = TreeSet(1,2,3)

• Functional way to get a matrix from text

  - by Elazar Leibovich

  I'm trying to solve some Google Code Jam problems, where an input matrix is typically given in this form: 2 3 #matrix dimensions 1 2 3 4 5 6 7 8 9 # all 3 elements in the first row 2 3 4 5 6 7 8 9 0 # each element is composed of three integers where each element of the matrix is composed of, say, three integers. So this example…

• Greasemonkey script for inserting math in gmail

  - by Elazar Leibovich

  I wish an easy way to communicate mathematical equations with gmail. There's a javascript script called AsciiMath, which should translate Tex-like equations into standard mathML. I thought that it would be nice to use this script with GM. I thought that before sending the email, this script would convert all the TeX-like…

• setTimeout(fun) with a single argument

  - by Elazar Leibovich

  The HTML5 specifications states that setTimeout can be run without the additional "timeout" argument which is supposed to say after how many milliseconds will the function "handler" be scheduled. handle = window . setTimeout( handler [, timeout [, arguments ] ] ) Schedules a timeout to run handler after timeout…

• comparing two angles

  - by Elazar Leibovich

  Given four points in the plane, A,B,X,Y, I wish to determine which of the following two angles is smaller ?ABX or ?ABY. I'd rather not use cos or sqrt, in order to preserve accuracy. In the case where A=(-1,0),B=(0,0), I can compare the two angles ?ABX and ?ABY, by calculating the dot product of the vectors X,Y,…

• Deploying only changed part of a website with git to ftp (svn2web for git)

  - by Elazar Leibovich

  I'm having a website with many big images file. The source (as well as the images) is maintained with git. I wish to deploy that via ftp to a bluehost-like cheap server. I do not wish to deploy all the website each time (so that I won't have to upload too many unchanged files over and over), but to do roughly the…

• Effects of the `extern` keyword on C functions

  - by Elazar Leibovich

  In C I did not notice any effect of the extern keyword used before function declaration. At first I thougth that when defining extern int f(); in a single file forces you to implement it outside of the files scope, however I found out that both extern int f(); int f() {return 0;} And extern int f() {return 0;}…

• graph library for scala

  - by Elazar Leibovich

  Is there a good library (or wrapper to Java library) for graphs, and/or graph algorithms in scala? This one seems to be quite dead. This is an example for the Dijkstra algorithm in scala, but I'm looking for a library a-la JGraphT.

• calculate intersection between two segments in a symmetric way

  - by Elazar Leibovich

  When using the usual formulas to calculate intersection between two 2D segments, ie here, if you round the result to an integer, you get non-symmetric results. That is, sometimes, due to rounding errors, I get that intersection(A,B)!=intersection(B,A). The best solution is to keep working with floats, and…

• Duplicating custom nodes in JavaFX

  - by Elazar Leibovich

  As far as I understand, duplicating nodes in JavaFX should be done with the Duplicator.duplicate function. It works fine when duplicating nodes whose types are included in JavaFX library, for example def dup = Duplicator.duplicate(Rectangle{x:30 y:30 width:100 height:100}); dup.translateX = 10; insert dup…

• printing long compilation lines with MS NMAKE

  I have a legacy MS NMAKE Makefile I need to fix a few bugs in. There are some very long command lines I wish to debug that are being executed using the NMAKE trick of "inline files": dep: cmd @<<tmpfilename cmd_args.. << When changing the line to dep: echo cmd @<<tmpfilename…

• Real life usage of the projective plane theory

  - by Elazar Leibovich

  I'm learning about the theory of the projective plane. Very generally speaking, it is an extension of the plane, which includes additional points which are defined as the intersection points of two parallel lines. In the projective plane, every two lines have an interesection point. Whether they're…

• A simple algorithm for polygon intersection

  - by Elazar Leibovich

  I'm looking for a very simple algorithm for computing the polygon intersection/clipping. That is, given polygons P, Q, I wish to find polygon T which is contained in P and in Q, and I wish T to be maximal among all possible polygons. I don't mind the run time (I have a few very small polygons), I…

• Functional programming approach for Java's input/output streams

  - by Elazar Leibovich

  I'm using Java's DataInputStream with scala to parse some simple binary file (which is very bad exprerience due to the lack of unsigned types, even in scala, but that's a different story). However I find myself forced to use mutable data structure, since Java's streams are inherently state…

• Access inner function variables in Javascript

  - by Elazar Leibovich

  In many frameworks, internal function variables are used as private variables, for example Raphael = (function(){ var private = function(a,b) {return a+b;}; var public = function(a) {return private(a,a);} var object = {mult2:public}; return object; })(); here, we cannot…

• Resources for memory management in embedded application

  - by Elazar Leibovich

  How should I manage memory in my mission critical embedded application? I found some articles with google, but couldn't pinpoint a really useful practical guide. The DO-178b forbids dynamic memory allocations, but how will you manage the memory than? preallocate everything in advance…

• Preallocating memory with C++ in realtime environment

  - by Elazar Leibovich

  I'm having a function which gets an input buffer of n bytes, and needs an auxillary buffer of n bytes in order to process the given input buffer. (I know vector is allocating memory at runtime, let's say that I'm using a vector which uses static preallocated memory. Imagine this is…
