• How do I get into a career as a programmer/development DBA?

  - by markle976

  About 8-9 years ago I started getting into programming as a hobby. I started with my TI-86 calculator, and then moved into using Visual Basic. After about a year I started playing around with HTML and JavaScript. Then I discovered Flash; I programmed with Actionscript 2.0 for about 2 years which lead me to start using Coldfusion. After a while I realized that A) I am not a designer, and B) with the way that things were going with AJAX, .NET, and PHP there wasn’t much future in Coldfusion/Actionscript. I had been working mostly as an administrative assistant, but about 3-4 years ago I got a position where I would be doing some web development, and assisting the system admin with supporting windows desktop PCs. I have gotten some decent experience over the past few years, but it has been spread out in somewhat disparate areas: I spend about 40% of my time writing PHP/MySQL and HTML/CSS, etc. I spend about 20% of my time helping users with PC questions. I spend about 20% of my time doing administrative things (mail-merges, excel, etc). I spend about 20% of my time managing / creating reports from our Access Database. I have also taught myself many things on my own, and now have a beginner’s level understanding of things like: Windows Server, Java, Linux, Objective-C, SQL Server, C#, C++, Ruby, Mac OSX, VBA, VBScript, and basic IP networks. I feel like I am in a bit of a rut – I want to get my career moving, but I am not sure what I need to do. If I practice with C# and SQL Server Express for a year will that be enough to get me in the door somewhere? Would it be easier to get a position if I teach myself Linux/Apache since I have more experience with PHP/MySQL?

• Git from localhost to remotehost with a team of three

  - by Mark McDonnell

  Hi, I'm completely new to Git. I've only just worked out how to use Github in a basic way (e.g. push my local file changes to Github - so I've not done 'pulling' down of content from Github and 'merging' it into my localhost version or anything like that). I had a look over at this existing question - Git: localhost remote development remote production - but I think it may have been a bit advanced for me at this stage as I didn't quite understand the terminology that most of the people were using. What I would like to achieve is to have a local server set-up that my team of developers can all 'push' to/'pull' from etc. And then have that local server upload any updated files automatically to our web server so we could see the updates live in the browser. I'm happy to get a server set-up in the office running Mac OSX Server and then installing Git on it and then getting the devs to write a shell script to push to the remote server but only if it was fairly easy for the devs local git to push to this new local server. I'm not a network engineer so I don't know what would need to be set-up for that to work, I know obviously we could set-up the server to be accessible via a local ip address like 192.168.0.xxx but not sure how that works with pushing to a git repository on that server? Would that literally be something like doing this on my local machine: git remote add MyGitFile git://192.168.0.xxx/MyGitFile.git ? Any ideas or advice you can give to a total Git newbie trying to help his team get a better work flow. Kind regards, Mark

• scanf segfaults and various other anomalies inside while loop

  - by Shadow

  while(1){ //Command prompt char *command; printf("%s>",current_working_directory); scanf("%s",command);<--seg faults after input has been received. printf("\ncommand:%s\n",command); } I am getting a few different errors and they don't really seem reproducible(except for the segfault at this point .<). This code worked fine about 10 minutes ago, then it infinite looped the printf command and now it seg faults on the line mentioned above. The only thing I changed was scanf("%s",command); to what it currently is. If I change the command variable to be an array it works, obviously this is because the storage is set aside for it. 1) I got prosecuted about telling someone that they needed to malloc a pointer* (But that usually seems to solve the problem such as making it an array) 2) the command I am entering is "magic" 5 characters so there shouldn't be any crazy stack overflow. 3) I am running on mac OSX 10.6 with newest version of xCode(non-OS4) and standard gcc 4) this is how I compile the program: gcc --std=c99 -W sfs.c Just trying to figure out what is going on. Being this is for a school project I am never going to have to see again, I will just code some noob work around that would make my boss cry :) But for afterwards I would love to figure out why this is happening and not just make some fix for it, and if there is some fix for it why that fix works.

• How do I generate reports in R?

  - by Maiasaura

  I've been struggling for a week now trying to figure out how to generate reports in R using either Sweave or Brew. I should say right at the beginning that I have never used Tex before but I understand the logic of it. I have read this document several times. However, I cannot even get a simple example to parse. Brew successfully converts a simple markup file (just a title and some text) to a .tex file (no error). But it never ever converts tex to a pdf. > library(tools) > library(brew) > brew("population.brew", "population.tex") > texi2dvi("population.tex", pdf = TRUE) The last step always fails with: Error in texi2dvi("population.tex", pdf = TRUE) : Running 'texi2dvi' on 'population.tex' failed. What am I doing wrong? The report I am trying to build is fairly simple. I have 157 different analysis to summarize. Each one has 4 plots, 1 table and a summary. I just want output plot 1,2,3,4 output table \pagebreak ... that's it. Can anyone help me get further? I use osx, don't have Tex installed. thanks

• Where can I find BLAS example code (in Fortran)?

  - by Feynman

  I have been searching for decent documentation on blas, and I have found some 315 pages of dense material that ctrl-f does not work on. It provides all the information regarding what input arguments the routines take, but there are a LOT of input arguments and I could really use some example code. I am unable to locate any. I know there has to be some or no one would be able to use these libraries! Specifically, I use ATLAS installed via macports on a mac osx 10.5.8 and I use gfortran from gcc 4.4 (also installed via macports). I am coding in Fortran 90. I am still quite new to Fortran, but I have a fair amount of experience with mathematica, matlab, perl, and shell scripting. I would like to be able to initialize and multiply a dense complex vector by a dense symmetric (but not hermitian) complex matrix. The elements of the matrix are defined through a mathematical function of the indices--call it f(i,j). Could anyone provide some code or a link to some code?

• Outgoing Emails (Git Patches) Blocked by Windows Live

  - by SteveStifler

  Just recently I dove into the VideoLAN open source project. This was my first time using git, and when sending in my first patch (using git send-email --to [email protected] patches), I was sent the following message from my computer's local mail in the terminal (I'm on OSX 10.6 by the way): Mail rejected by Windows Live Hotmail for policy reasons. We generally do not accept email from dynamic IP's as they are not typically used to deliver unauthenticated SMTP e-mail to an Internet mail server. http:/www.spamhaus.org maintains lists of dynamic and residential IP addresses. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit http://postmaster.live.com for email delivery information and support They must think I'm a spammer. I have a dynamic IP and my ISP (Charter) won't let me get a static one, so I tried editing git preferences: git config --global user.email "[email protected]" to my gmail account. However I got the exact same message again. My guess is that it has something to do with the native mail's preferences, but I have no idea how to access them or modify them. Anybody have any ideas for solving this? Thanks!

• Cannot connect to Github?

  - by user2973438

  so I tried to push some updates onto my repo on github via terminal on Mac OSX 10.8.4 and it doesn't work. I've been getting the same error many times: Lillys-MacBook-Air:Yuewei Lilly$ git push origin master error: Failed connect to github.com:443; Operation timed out while accessing https://github.com/lillybeans/Yuewei.git/info/refs?service=git-receive-pack fatal: HTTP request failed Some background: I've pushed many projects onto github before using terminal (when I was in Canada). I am currently in Shanghai, China, could it be the GFW? But when I was in Beijing, I was able to push projects onto github still. when I do ping github.com: Lillys-MacBook-Air:Yuewei Lilly$ ping github.com PING github.com (192.30.252.131): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 ping: sendto: No route to host Request timeout for icmp_seq 2 ping: sendto: Host is down Request timeout for icmp_seq 3 ping: sendto: Host is down Request timeout for icmp_seq 4 ping: sendto: Host is down Request timeout for icmp_seq 5 ping: sendto: Host is down Request timeout for icmp_seq 6 ping: sendto: Host is down Request timeout for icmp_seq 7 ^C --- github.com ping statistics --- 9 packets transmitted, 0 packets received, 100.0% packet loss Lillys-MacBook-Air:Yuewei Lilly$ I have ShadowSocks (proxy) turned on.

• How to maintain long-lived python projects w.r.t. dependencies and python versions ?

  - by Gyom

  short version: how can I get rid of the multiple-versions-of-python nightmare ? long version: over the years, I've used several versions of python, and what is worse, several extensions to python (e.g. pygame, pylab, wxPython...). Each time it was on a different setup, with different OSes, sometimes different architectures (like my old PowerPC mac). Nowadays I'm using a mac (OSX 10.6 on x86-64) and it's a dependency nightmare each time I want to revive script older than a few months. Python itself already comes in three different flavours in /usr/bin (2.5, 2.6, 3.1), but I had to install 2.4 from macports for pygame, something else (cannot remember what) forced me to install all three others from macports as well, so at the end of the day I'm the happy owner of seven (!) instances of python on my system. But that's not the problem, the problem is, none of them has the right (i.e. same set of) libraries installed, some of them are 32bits, some 64bits, and now I'm pretty much lost. For example right now I'm trying to run a three-year-old script (not written by me) which used to use matplotlib/numpy to draw a real-time plot within a rectangle of a wxwidgets window. But I'm failing miserably: py26-wxpython from macports won't install, stock python has wxwidgets included but also has some conflict between 32 bits and 64 bits, and it doesn't have numpy... what a mess ! Obviously, I'm doing things the wrong way. How do you usally cope with all that chaos ?

• Create a model that switches between two different states using Temporal Logic?

  - by NLed

  Im trying to design a model that can manage different requests for different water sources. Platform : MAC OSX, using latest Python with TuLip module installed. For example, Definitions : Two water sources : w1 and w2 3 different requests : r1,r2,and r3 - Specifications : Water 1 (w1) is preferred, but w2 will be used if w1 unavailable. Water 2 is only used if w1 is depleted. r1 has the maximum priority. If all entities request simultaneously, r1's supply must not fall below 50%. - The water sources are not discrete but rather continuous, this will increase the difficulty of creating the model. I can do a crude discretization for the water levels but I prefer finding a model for the continuous state first. So how do I start doing that ? Some of my thoughts : Create a matrix W where w1,w2 ? W Create a matrix R where r1,r2,r3 ? R or leave all variables singular without putting them in a matrix I'm not an expert in coding so that's why I need help. Not sure what is the best way to start tackling this problem. I am only interested in the model, or a code sample of how can this be put together. edit Now imagine I do a crude discretization of the water sources to have w1=[0...4] and w2=[0...4] for 0, 25, 50, 75,100 percent respectively. == means implies Usage of water sources : if w1[0]==w2[4] -- meaning if water source 1 has 0%, then use 100% of water source 2 etc if w1[1]==w2[3] if w1[2]==w2[2] if w1[3]==w2[1] if w1[4]==w2[0] r1=r2=r3=[0,1] -- 0 means request OFF and 1 means request ON Now what model can be designed that will give each request 100% water depending on the values of w1 and w2 (w1 and w2 values are uncontrollable so cannot define specific value, but 0...4 is used for simplicity )

• building a gl3 app under cygwin

  - by user445264

  i've got a small opengl 3.2 app that i've been developing on linux using the standard gnu tools (gmake/gcc). the code seems pretty portable--i had no problems running it on osx until i started using gl3 features that the mac mini gl drivers don't seem to support. i've got a bootcamp partition with windows xp on the same mini, and i'd like to run my app there if possible. the windows drivers definitely support gl 3.2, but i'm having trouble linking. this seems like a really common issue, but i haven't found any answers online that address using opengl 1.2 under cygwin. i'm using glew-1.5.5 and linking like so: g++ -o glToy *.o -L/cygdrive/c/Program\ Files/glew-1.5.5/lib -lglew32 -lglut32 -lglu32 -lopengl32 but i get a whole lot of this sort of output: Program.o:/home/Jacob/glToy/Program.cpp:134: undefined reference to `__imp____glewUseProgram' Program.o:/home/Jacob/glToy/Program.cpp:235: undefined reference to `__imp____glewActiveTexture' Program.o:/home/Jacob/glToy/Program.cpp:73: undefined reference to `__imp____glewGetShaderiv' ... any ideas what i'm doing wrong? or perhaps this isn't a workable setup? other ideas for getting this going on the mac mini (2009 version)? thanks!

• gevent urllib is slow

  - by djay

  I've created a set of demos of a TCP server however my gevent examples are noticely slower. I'm sure must be how I compiled gevent but can't work out the problem. I'm using OSX leopard using fink compiled python 2.6 and 2.7. I've tried both the stable gevent and gevent 1.0b1 and it acts the same. The echo takes 5 seconds to respond, where the other examples take <1sec. If I remove the urllib call then the problem goes away. I put all the code in https://github.com/djay/geventechodemo To run the examples I'm using zc.buildout so to build $ python2.7 bootstrap.py $ bin/buildout To run the gevent example: $ bin/py geventecho3.py & [1] 80790 waiting for connection... $ telnet localhost 8080 Trying 127.0.0.1... ...connected from: ('127.0.0.1', 56588) Connected to localhost. Escape character is '^]'. hello echo: avast This will take 3-4 seconds to respond on my system. However the twisted example $ bin/py threadecho2.py or the twisted example $ bin/py twistedecho2.py Is less than 1s. Any idea what I'm doing wrong?

• HTML5 audio with PHP script does not work on iPad/Iphone

  - by saulob

  Ok, I'm trying to play an HTML audio code on iPad but does not work. I created one PHP script to send to the MP3 request to the HTML5 audio code mp3_file_player.php?n=mp3file.mp3 The player is here: http://www.avault.com/news/podcast-news/john-romero-podcast-episode-80/ You will see that works on every HTML5 supported browser even on my iPod Touch. But does not work on iPad/iPhone, even on Safari on Mac OSX (I tried on Safari/Windows, worked fine) This is my PHP code: header("X-Powered-By: "); header("Accept-Ranges: bytes"); header("Content-Length: ". (string)(filesize($episode_filename)) .""); header("Content-type: audio/mpeg"); readfile($episode_filename); exit(); Everything works fine, the MP3 has the same headers like reading the mp3 directly. HTTP Headers from direct file access: (Status-Line) HTTP/1.1 200 OK Date Mon, 31 May 2010 20:27:31 GMT Server Apache/2.2.9 Last-Modified Wed, 26 May 2010 13:39:19 GMT Etag "dac0039-41d91f8-4877f669cefc0" Accept-Ranges bytes Content-Length 50656162 Content-Range bytes 18390614-69046775/69046776 Keep-Alive timeout=15, max=100 Connection Keep-Alive Content-Type audio/mpeg HTTP Header from my PHP script: (Status-Line) HTTP/1.1 200 OK Date Mon, 31 May 2010 20:27:08 GMT Server Apache/2.2.9 Accept-Ranges bytes Content-Length 69046776 Keep-Alive timeout=15, max=100 Connection Keep-Alive Content-Type audio/mpeg The only thing different it's the Content-Range, I even tried to add it, but if I use it the player will not work on my Ipod Touch. So I removed. Thank you very much.

• Error loading il8n console in CakePHP 1.3

  - by inkedmn

  I'm trying to generate the .po files for the site I'm working with. When I run this command from within the console directory: Warning: strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for 'PDT/-7.0/DST' instead in /Users/bkelly/Development/[redacted]/www/trunk/about/trunk/cake/libs/cache.php on line 570 Warning: strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

This also happens if I issue ./cake il8n help . The bake console seems to load fine (no errors, takes me to the expected menu). I'm running CakePHP 1.3.0 under Mac OSX 10.6 (using MAMP). Cake appears to be functioning normally otherwise. Thanks!

• Give the mount point of a path

  - by Charles Stewart

  The following, very non-robust shell code will give the mount point of $path: (for i in $(df|cut -c 63-99); do case $path in $i*) echo $i;; esac; done) | tail -n 1 Is there a better way to do this? Postscript This script is really awful, but has the redeeming quality that it Works On My Systems. Note that several mount points may be prefixes of $path. Examples On a Linux system: cas@txtproof:~$ path=/sys/block/hda1 cas@txtproof:~$ for i in $(df -a|cut -c 57-99); do case $path in $i*) echo $i;; esac; done| tail -1 /sys On a Mac osx system cas local$ path=/dev/fd/0 cas local$ for i in $(df -a|cut -c 63-99); do case $path in $i*) echo $i;; esac; done| tail -1 /dev Note the need to vary cut's parameters, because of the way df's output differs: indeed, awk is better. Answer It looks like munging tabular output is the only way within the shell, but df /dev/fd/impossible | tail -1 | awk '{ print $NF}' is a big improvement on what I had. Note two differences in semantics: firstly, df $path insists that $path names an existing file, the script I had above doesn't care; secondly, there are no worries about dereferncing symlinks. It's not difficult to write Python code to do the job.

• Android newbie installing Eclipse, having issues....

  - by Jeff

  I am a web developer, new to app development and Java/Android. I am about to follow some tutorials to get started learning but I'm running into a wall. The Android dev site says the recommended way to build Android apps is in Java using the Eclipse plug in. So I downloaded Eclipse Classic and unzipped it on to get this error: "A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: /Users//Desktop/eclipse/Eclipse.app/Contents/MacOS/jre/bin/java java in your current PATH" Any idea what the issue is and how I can fix it? Again, newbie to java, jre, android, so I apologize if this question has already been asked. In my research I've discovered that most of the posts or solutions I've found are tough for me to follow. There's always a few unclear items that are probably prohibiting me from getting the answer I need. So I'm hoping someone can walk me through installing or configuring whatever I need to regarding Java so I can continue installing Eclipse and begin learning. I should probably note that I'm on Mac OSX 10.6.6 Snow Leopard. Please let me know if you need any other info. Thanks so much in advance for any and all help!!!

• Tools for managing code deployment/versioning for IIS / Windows enviroments

  - by RizwanK

  I've got a strong background in Linux and OSX, and just left a job where I was architecting systems based on those platforms. Now I've got a Windows Server running IIS that has a number of different websites that it hosts. Most of them are just a bunch of HTML, JS and Images, with some ASP for some customer tools. (Each website has a different set of customer tools, or they are the same tools, but with minor code changes between them.) I'm also adding a develop web server with the same code, but the 'bleeding edge' stuff. I need an effective way of managing changes and updates to the overall codebase (henceforth referring to both the images and the html and the asp, for all the sites). When a dev (or webmaster) checks in changes, I want it to show up automatically on the developer server, but should be manually pushed out to the live server. I'd be tempted to just make the websites SVN repositories, but I'd be concerned about the overhead of having the webdeveloper having to log into the server and trigger an SVN update via commandline/tortise (and heaven forbid, manage tags). Ideally I'd also manage IIS profile settings between the systems, but the major need is to be able to manage the process, and expose it to our ASP developer, and our webmaster, both of which are used to just FTPing up the files to the live site. So, any recommendations on tools (beyond some SVN hacking with BAT files + teaching the webmaster how to log into the server and do updates) or workflows that would help this out? I even considered an RPM type package (or some Windows equivalent, of course) to manage the live server, but that seems like a bit too much overhead. Thanks.

• Could not launch console app with xCode 4.4

  - by lp1756

  I have a project with two targets -- an iOS app and an OSX console app. The latter was created using Xcode File-New Target and selecting "Command Line Tool". This console app is used to prep a default database needed by the iOS app -- using CoreData. This has been working fine until I upgraded to Mountain Lion and xCode 4.4. Now when I try to run the command line tool I get a "Could Not Launch -- permission denied" error. I have tried playing around with signing certificates, to no avail. Interestingly if I create a new "hello, world" command line tool in a new project it works just fine -- and it is not signed at all. I checked the file and it has -rwxr-xr-x permission. In the debugger the app fails on startup even before it tries to access the moms. If I try to run this outside of the debugger at the command line, it ends with a kill 9 message. Any ideas would be greatly appreciated.

• Has anyone ever had OpenCV work with Python 2.7 on MacOS 10.6?

  - by ?????

  I've been trying on and off for the past 6 months to get OpenCV to work with Python on MacOS. Every time there's a new release, I try again and fail. I've tried both 64-bit and 32-bit, and both the xcode gcc and gcc installed via macports. I just spend the past two days on it, hopeful that the latest OpenCV release, that appears to include Python support directly would work. It doesn't. I've also tried and failed to use this: http://code.google.com/p/pyopencv/ I've been using OpenCV with C++ or Microsoft C++/CLI for the past few years, but I'd love to use it with Python on a Mac because that is my primary development environment. I'd love to hear from anyone who's actually been able to get the opencv python examples to run under Mac OS 10.6, either 32 or 64-bit. My last attempt was to follow the instructions on this page http://recursive-design.com/blog/2010/12/14/face-detection-with-osx-and-python/ with a clean, fresh install of 10.6 on a 64-bit capable Mac. My PYTHONPATH is set, and I can see the cv library in it. But an "import cv" from python fails. Previously, the closest I've ever gotten (again, staring on a clean, fresh 10.6 install) was this: Python 2.7.1 (r271:86882M, Nov 30 2010, 10:35:34) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import cv Fatal Python error: Interpreter not initialized (version mismatch?) Abort trap thrilllap-2:~ swirsky$ I've seen a lot of folks answering similar questions here, but have never seen an definitive answer for it.

• How to access remote mysql host on Ubuntu inside VMware?

  - by Nick Grossman

  Hi, I'm running Ubuntu 10.10 inside VMware fusion on Mac OSX Snow Leopard. Inside ubuntu, I'm attempting to use command-line mysql to connect to a database hosted on a separate web server. For some reason, mysql misinterprets the remote hostname as a local address, and is not able to connect to the database. Steps: (from ubuntu inside VMware) mysql -u <my-username> -h mysql-2.sandbox.wrkng.net -p Enter Password: <my password> expected: to log into mysql got: ERROR 1045 (28000): Access denied for user '<my-username>'@'c-71-233-98-90.hds1.ma.comcast.net' (using password: YES) Note that the hostname referenced in the error message is different than the one I inputted to the mysql command. Also, performing the same command from the Mac (host of the VM) terminal successfully connects to the database. I am not seasoned with VMware or linux, so I may be missing something obvious here -- it seems like somewhere along the way either ubuntu or the VM has a networking issue. Note also that accessing the internet via ubuntu inside the VM works fine. Any help is greatly appreciated. Thanks!

• PNG's In Mac on Java cause massive CPU usage

  - by alexganose

  Hey, I've been having this problem for a while now and I was hoping someone could help. I make small games using Java on Mac OSX 1.6.3 and if I use PNG's as the image format my CPU usage by Java skyrockets to say 50% (on a very small 2D game). However if I use GIF as the format my CPU usage by Java stays constant at 10% which is reasonable. What is causing this problem?? It occurs on every game I develop using PNG's so I always just switch to GIF's. The problem is now that i need to use a PNG for its variable alpha properties rather than just plain transparency. This is not available using GIF's. The problem is present on Java SE 6 and previous versions. I am using an early 2009 Mac Book Pro 15". The problem does not occur on a Windows PC running the same game. The CPU usage due to Java using PNG's on a Windows PC (I have tried XP, Vista and 7) is always constantly low at ~10%. Any help would be greatly appreciated. Thanks :)

• How to speed up drawing of scaled image? Audio playback chokes during window resize.

  - by Paperflyer

  I am writing an audio player for OSX. One view is a custom view that displays a waveform. The waveform is stored as a instance variable of type NSImage with an NSBitmapImageRep. The view also displays a progress indicator (a thick red line). Therefore, it is updated/redrawn every 30 milliseconds. Since it takes a rather long time to recalculate the image, I do that in a background thread after every window resize and update the displayed image once the new image is ready. In the meantime, the original image is scaled to fit the view like this: // The drawing rectangle is slightly smaller than the view, defined by // the two margins. NSRect drawingRect; drawingRect.origin = NSMakePoint(sideEdgeMarginWidth, topEdgeMarginHeight); drawingRect.size = NSMakeSize([self bounds].size.width-2*sideEdgeMarginWidth, [self bounds].size.height-2*topEdgeMarginHeight); [waveform drawInRect:drawingRect fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1]; The view makes up the biggest part of the window. During live resize, audio starts choking. Selecting the "big" graphic card on my Macbook Pro makes it less bad, but not by much. CPU utilization is somewhere around 20-40% during live resizes. Instruments suggests that rescaling/redrawing of the image is the problem. Once I stop resizing the window, CPU utilization goes down and audio stops glitching. I already tried to disable image interpolation to speed up the drawing like this: [[NSGraphicsContext currentContext] setImageInterpolation:NSImageInterpolationNone]; That helps, but audio still chokes during live resizes. Do you have an idea how to improve this? The main thing is to prevent the audio from choking.

• Background-image is not displaying in Firefox

  - by goa

  Strange thing happens. Background-image is not displaying in Firefox under some versions of WindowsXP and Windows Vista, but displays in Firefox under Mac OSX. It also displays in IE. This is CSS: .cherry_banner { background: url("library/media/images/cherry_banner_top.png") no-repeat; width: 276px; display:block; min-height:100px; padding-top: 13px; color: #fdfdfd; margin-bottom:20px; } .cherry_banner a { color: #fdfdfd; } .cherry_banner a:hover { text-decoration:underline; } .cherry_banner li { list-style-type:none; } .cherry_banner h2 { font-size: 18px; margin-bottom: 10px; } .chb_text1 { background: url("library/media/images/cherry_banner_pixel.png") repeat-y; } .chb_text2 { background: url("library/media/images/cherry_banner_bottom.gif") bottom no-repeat; padding: 4px 14px 24px 25px; } And this is html: <div id="linkcat-8" class="cherry_banner tpt"><div class="chb_text1"><div class="chb_text2"> <h2>??? ?????????</h2> <ul class='xoxo blogroll'> <li><a href="http://inveda.ru/jyotish/naksatra-calendar/">???????? ?????????? ?????????????? ????????? ????????????? ??? ?? 2010?.</a></li> </ul> </div></div></div> You can see on http://www.inveda.ru - right column - red banner.

• Can't clone gitosis-admin.git local from my snow leopard server running gitosis

  - by joggink

  I've installed gitosis as described here: http://gist.github.com/264304 One of the things that I had to adjust was to give my git user permissions to use ssh (which I did trough server admin - access - ssh and added the 'git' user). When I ssh from my local machine (mac osx) as the git user, I get this response: PTY allocation request failed on channel 0 bash: gitosis-serve: command not found Connection to 10.0.0.108 closed. Which I think is normal, because in Pro GIT the author says you should get something like this if you try ssh'ing to the server using your git user: PTY allocation request failed on channel 0 fatal: unrecognized command 'gitosis-serve schacon@quaternion' Connection to gitserver closed. So far so good, I think? Now when I try to clone my gitosis-admin.git repository using this command: $git clone [email protected]:gitosis-admin.git I get this: Initialized empty Git repository in /Users/joggink/gitosis-admin/.git/ bash: gitosis-serve: command not found fatal: The remote end hung up unexpectedly So after doing some searching, I found an answer here on serverfault claiming I should use ssh:// as protocol for my git clone (which I thought is the default git protocol?) However, when I try: $git clone ssh://[email protected]:gitosis-admin.git This is the response: The authenticity of host ' (::1)' can't be established. RSA key fingerprint is 80:4d:77:c7:78:cb:c9:42:e3:82:06:7c:fe:c0:08:ce. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '' (RSA) to the list of known hosts. Password: Password: Password: Permission denied (publickey,keyboard-interactive). fatal: The remote end hung up unexpectedly When I type in my own password (because my git user has no password), I get following error: The authenticity of host ' (::1)' can't be established. RSA key fingerprint is 80:4d:77:c7:78:cb:c9:42:e3:82:06:7c:fe:c0:08:ce. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '' (RSA) to the list of known hosts. Password: bash: git-upload-pack: command not found fatal: The remote end hung up unexpectedly I added my upload-pack location as followed: $git clone -u /usr/local/git/bin/git-upload-pack ssh://[email protected]:gitosis-admin.git I get the error that gitosis-admin.git isn't a git repo... Initialized empty Git repository in /Users/joggink/gitosis-admin/.git/ The authenticity of host ' (::1)' can't be established. RSA key fingerprint is 80:4d:77:c7:78:cb:c9:42:e3:82:06:7c:fe:c0:08:ce.

Password: fatal: '[email protected]:gitosis-admin.git' does not appear to be a git repository fatal: The remote end hung up unexpectedly I've been searching for a solution for almost a week now, and every topic I've found on the internet gives no result...

• Can I set up two computers up with the same monitors/keyboard/mouse in a modular way?

  - by CodeJunkie

  I have a desktop computer computer (running Windows 7), and a laptop (running OSX Mountain Lion, and maybe Ubuntu 12 eventually). When the laptop is at home, I want both the desktop and the laptop to use the same (2+) monitors, the keyboard, and the mouse (or mice, if I add a track pad). I know about KVM switches, but I want something more complicated. I like to use Synergy to use both computers with one keyboard and mouse at the same time. Synergy requires that the keyboard and mouse be connected to one computer (the server), which shares them with other computers (clients) over wifi. the issue is that when one computer isn't logged in, Synergy doesn't work on it. Sometimes, I want my laptop to be the server (physically connected to the keyboard and mouse), and sometimes I want my desktop to be the server. This means that I need the keyboard/mouse/other USB devices to be able to switch computers without me playing musical plugs. To complicate things further, I don't always want the same desktop set up in terms of monitors. Sometimes, I want the desktop to have both monitors. Other times, I want the laptop to control both monitors. Sometimes I want the desktop to control one monitor, and the laptop to control the other. In any case, the keyboard and mouse need to be able to be physically connected to either computer without lots of fussing with plugs. This breaks down to at least this set of possible combinations: Desktop controls both monitors, and has a physical connection to keyboard and mouse Laptop controls both monitors, and has a physical connection to keyboard and mouse Desktop and laptop each control a monitor, but the desktop has a physical connection to the keyboard and mouse (which it shares with the laptop via wifi) Desktop and laptop each control a monitor, but the laptop has a physical connection to the keyboard an mouse (which it shares with the desktop via wifi) some usb devices connected via a usb hub need to be able to switch physical connection between computers, ideally without the keyboard and mouse switching computer connection There may be other combinations, but these are the main ones at the moment. Basically, I need a KVM switch which allows me to switch individual monitors/keyboard/mouse/usb hub between computers independently of each other, or a better solution. How can I set two computers up with the same monitors/mice/keyboard/usb hub without having to switch everything to one computer or the other all at the same time?

• getting Internet connection sharing working in a slightly more complicated configuration

  - by tirichitirca t

  I have the following configuration: Computer A - Mac OSX 10.8.4, wireless & wired adapters Computer B - Windows 7 (64 bit), wireless & wired adapters, has internet connection via the wired adapter (ethernet) d-link wired/wireless router. Problem to solve: Connect from computer A to the internet through the wired connection of computer B. I tried the following: I set up a local network between A and B using the d-link router. The configuration is this: D-link router - 192.168.0.1 A - wired connection to the d-link router, static 192.168.0.101 (I could have used the wireless but I preferred the wired connection) B - wireless connection to the d-link router DHCP 192.168.0.102 (but I made sure it always gets the same address) B - wired connection to the internet using some address that begins with 10.x.y.z. In this configuration A can see B. I enabled ICS on the wired adapter of B. I set up the Gateway of A to point to B and DNS servers to point to the DNS servers specified for the 10.x.y.z address. It doesn't work, A goes only as far as B. It can ping the 10.x.y.z address of B though. I then found this article: http://terrybritton.com/windows-internet-connection-sharing-ics-not-working-with-linux-bridging-is-the-solution-916/. Terry is suggesting that a bridge should be defined on B between the two connections. I tried that but basically computer B is screwed as soon as I create the bridge. It can't connect to the internet anymore. It is as if the network bridge seems to think the traffic to the internet should go from the wired connection to the wireless and not the other way around. The other thing that puzzles me is the router itself. In general the router needs an internet address. In a normal configuration it is the router that gets the ip address and the internet traffic goes through the router. In my case I am not interested in that. So, any suggestions to get this working? I wouldn't shy away from using a commercial software but I would think windows 7 should allow me to do it. Thanks
