  • How to connect Samsung Galaxy S3 via USB?

    - by dez93_2000
    Connecting as either MTP or PTP: neither allows one to see pictures saved as default by phone camera to DCIM folder on external SD card. Similar problems with previous models (e.g. S2) were solvable by 'usb utilities' in wireless & networking settings, but this is no longer present. Other suggestions have mentioned uninstalling various libraries... but I don't wanna just start cutting stuff without knowing it'll help. Any thoughts on how to mount a Samsung Galaxy S3 over USB?

  • Developing a computer system based on Nand2Tetris [on hold]

    - by Ryan
    I recently finished a book called Nand2Tetris (nand2tetris.org) where I built my own computer system from scratch with its own machine language, assembly code, and a high level language called Jack that's translated to Hack binary. However, I feel like the "computer" I built throughout the course of this book (called the Hack computer) is a bit too simple for various reasons: 1) There are only two registers (D and A), whereas most computers have much more 2) Peripheral devices like mouse and keyboard have to be directly implemented 3) Peripheral devices use a pre-planned shared memory map to communicate with the CPU instead of using interrupts (which aren't covered at all) 4) Jack (the high level language) code doesn't compile to Assembly code directly, instead it compiles to an intermediate language, which in turn gets translated to Assembly. 5) There is no ROM or permanent storage device, everything is stored in RAM 6) No support for colored monitor, networking or sound I would like to build a more complicated computer system now based on what I've learned from Nand2Tetris. Does anyone know of any good resources or books to get started on this? (BTW by computer system I mean software that can emulate the hardware of a virtual computer with its own unique instruction set)

  • Could anyone suggest me some image manipulation techniques to be added to my image viewer??

    - by avi
    Hello, I'm trying to develop a small image viewer just as an exercise to sharpen my programming skills. So far , all the features that I could think of adding to it are zooming in and out, inverting the colors of the image and resizing. Could anyone suggest me a few more features?? You are also welcome to suggest anything which has not been implemented yet. I would like to take it as a learning challenge. Thanks.

  • Ensuring ethernet is configured before continuing init scripts.

    - by Pete Ashdown
    Is there a better way to ensure that an ethernet port is configured before continuing through startup init scripts? When 802.3ad bonded ethernet is configured on Ubuntu, it takes some time before it finishes protocol negotiation and starts passing packets, because the networking script just configures, but does not verify that traffic is being passed. As a result, this can throw off some of the other network dependent scripts, like the init for drbd. Right now, I just have a loop that pings the gateway in a startup script, but this seems less than optimal: GATEWAYIP=10.0.0.1 while ( ! ping -c 1 $GATEWAYIP ); do echo gateway not up done

  • What software is responsible for connecting to the wireless net specified in /etc/network/interfaces?

    - by zuba
    I'm curious what software (package, utility in bin's) handle interface parameters in /etc/network/interfaces and decides to connect to the specified wireless net. I use wifi usb stick dlink DWL-110 attached to wlan0 with ndiswrapper driver. Sometimes wlan0 sees my wifi net - iwlist wlan0 scan shows it, but does not connect to it - iwconfig shows AP Not-Associated, until I replug the stick. Neither reinserting module with ndiswrapper, not ifdown/ifup or restarting networking helps. That is why I need to know what OS entity handles connection/reconnection to wireless net. EDIT: shame on me, I use wireless-tool package with wep encryption

  • Kubuntu 12.04 Won't let me search for wireless network

    - by Bora George
    Hello I'm running a brand new Kubuntu 12.04 single boot on my laptop, this is the first time I tried connecting to a wireless network. I tried using the network manager app allready on the task bar, but it doesn't let me tick the column to search for wireless networks, i.e. it will untick it automaticaly, it's dissabled by the software or the hardware, but I doubt it. I've tried searching the other questions on this site, and I can't see anything which helps with my problem. I know my wireless card is a Atheros AR9285, I don't think I installed any firmware for it, I'm sorry I can't offer more info but I'm completely new to networking and all that I have for the network to connect to are it's name and password of course.

  • Wireless network unstable and often WPA2 protected networks just don't work

    - by Pedro
    I have an issue with my wireless network,so that the connection is working for only a few minutes, after which my browser no longer is able to load pages, even if the wireless is still active/connected. Furthermore, most of the time WPA2-personal protected networks don't work, (yesterday was the first time it worked - for a few minutes). By "don't work" I mean that it seems to successfully connect, but the browser can't load pages. I am running Ubuntu 10.10 32bit, and my wireless card is a RaLink rt3090. No changes have been done to any settings since Ubuntu was installed - networking began working on its own after the installation - but as described in first paragraph not very well.

  • What are good JS libraries for game dev? (HTML5)

    - by acidzombie24
    If i decide to write a simple game both text and graphical (2d) what libs may i use? Assuming we are using a HTML5 compatible browser. The main things i can think of Rendering text on screen Animating sprites (using images/css) Input (capturing the arrow keys and getting relative mouse positions) Perhaps some preloading resource or dynamically loading resources and choosing order Sound (but i am unsure how important this will be to me at first). Perhaps with mixing and chaining sounds or looping forever until stop. Networking (low priority) to connect a user to another or to continuously GET data without multiple request (i know this exist but i dont know how easy it is to setup or use. But this isnt important to me. Its for the question).

  • Java enviroment book recommendations

    - by ipavlic
    I come from a C# background and would like to learn Java. Programming and Java as a language are not a problem. What is bewildering to me is the sheer amount of various choices in "Java environment" - Ivy, Maven, Ant, JAXB, Glassfish, JBoss, Struts, Spring are just some of the names that I keep seeing. I am looking for "who is who" and "who works together" beginner's guide. Is there such a book? Something similar?

  • vbscript help needed [migrated]

    - by Romeo
    I am trying to move a group of files with in a group of folders named recup_dir.1 through recup_dir.535 into a single folder so that all the files will be out of the folders and just in the single folder. I know I will need to use a loop to move the files and probably concatenation to go from recup_dir.1 to recup_dir.535 but I just am not that skilled in programming please help!! I just want it to automate the copying and moving of the files rather than do it manually.

  • Career advice: stay with PHP or start a new career in something else ( .Net?)

    - by Christian P
    I'm planning on moving to NY in 6-12 months tops, so I'm forced to find a new job. When I'm planing to start my life in another city it's also probably a good time to think about career changes. I've found a lot of different opinions about PHP vs .Net vs Java and this is not topic here. I don't want to start a new fight about which language is better. Knowing programming language is not the most important thing for being a software developer. To be a really good developer you need to know OOP, design patterns, testing... and language is just a tool to make things happen. So back to my question. I have mixed experience in IT - 1 year as an IT support guy (Windows administration and support), around 2 years of experience in embedded programming (VB.Net 2005) and for the last 2 years I'm working with PHP/MySQL. I have worked with Magento web shop, assisted in some projects in Symfony, modified few Drupal sites. My main concerns are following: Do I continue to improve my skills in PHP e.g. to start learning some major PHP framework like Zend, Symfony maybe get some PHP certification. Or do I start learning .NET or Java. I'm more familiar to .NET so I'll probably choose it if choice falls between .NET and Java ( or you could convince me to choose Java :). Career-wise, I don't know what is the best choice. Learning new framework and language is more time consuming then improving my existing skills in PHP. But with .NET you have a lot of possibilities (Windows 7 Phone development, Silverlight, WPF) and possibly bigger chances to find better jobs. PHP jobs are less payed then .NET, at least, according to my researches (correct me if I'm wrong). But if I start now with .NET I'm just a beginner and my salary will be low. I need at least 2+ years of experience in some language to even try to find some job that is paying higher than $50-60k in NY. My main goal in next 2-3 years is to try to find a job in a $60-80k category. Don't get me wrong, I'm not just chasing money, but money is an important factor when you're trying to start a family. I'm 27 years old and I feel that there isn't a lot of room for wrong decisions regarding my career, so any advice will be very welcome. Update Thank you all for spending time to help me with my problem. All of the answers and comments have been very helpful. I have decided to stick with PHP but also to learn C# and Silverlight 4. We'll see where the life will take me.

  • Apress "Pro DLR in .NET 4' - ISBN 978-1-430203066-3 - Conclusion

    - by TATWORTH
    Having finished Pro DLR in .Net 4, I have concluded that this is a book that needs to be read through several times and the examples worked through.  Since the Dynamic Language Runtime is as much a radical change as the the original Common Language Runtime, this is hardly surprising. Ultimatly the DLR will enable more niche programming languages, hence I recommend this book to Dot Net teams for when they have a requirement that justifies the effort.

  • XNA: Runtime differences in ClickOnce install versus development version

    - by Sean Colombo
    I have a game written in XNA, and I use ClickOnce installers to distribute the game to testers. I keep once computer as a test machine which does NOT have development environments installed, so that I can test the installed version. We've found a reproducible bug in our game, but the bug ONLY occurs on the non-development machines that use the ClickOnce installer. The bug is related to some of our code for moving around 3D objects and is not tied to Networking or GamerServices. Are there known differences in the ClickOnce runtime and the version on dev? Are there any best-practices for debugging something like this?

  • MIX10: Yet another way to view video content sessions using their OData feed

    Well, MIX10 is over. It was a great time to meet a lot of people and see friends from afar. As anyone knows, the networking is a HUGE part of being in-person at any conferencethat vibe, value and friendship cannot be matched online. But the sessions there were a TON of them. It is quite impossible to be in 3 places at one time. Thankfully the MIX team recorded all regular sessions and make them available for viewing online or offline. For you Silverlight developers here are my pics to ensure you...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How should I land my next consulting gig? [closed]

    - by MrOodles
    For the last couple of years, I've been working on speculative projects, expanding my skillset with side work, and paying the bills while having a blast consulting for startups. However, for a number of personal reasons, I need to spend the next 6-9 months maximizing my cash income. I want to put this into effect starting in early August. So that means I have one month to put the necessary client list/portfolio/resume together to start making this happen. As a programmer, I am very proficient in building Django web apps. I can write the necessary SQL, python, javascript, and css to build every part of a Django app, and then do the system administration necessary to deploy on AWS using EC2. I can also rig up a CDN to work seemlessly with the app using S3 and Cloudfront. I have built GIS applications using GeoDjango and PostGIS, and I have constructed social video apps by implementing Encoding.com as a service to prepare raw video files for consumption on the web. I am also moderately proficient in programming PHP, Java, and C#. I have built web apps in PHP, and desktop apps in Java and C#. I have dabbled with Android applications and iPhone apps, but nothing I would show off. I have experience doing SEO, social media marketing, and content marketing. Many of my clients have needed their apps promoted after they were built, and I was always happy to oblige when I could. I have also worked with biometrics technology including fingerprints for government contractors. This was as much a business analyst role as it was a programming gig, as I had to help answer RFPs, make checklists, and work around reems and reems of regulations to build applications that met very large bureaucratic requirements. I only have two real requirements for my next gig(s): 1) Work remotely. I live in North East Ohio, and I don't plan on leaving, but I wouldn't mind traveling one or two weeks out of every month to service clients who need on-site help. 2) $60.00hr-$∞ USD contracting rate. So what should I do for the next 30 days to achieve this? Should I target some large company and learn the requisite buzzwords to impress them? Should I learn some new language or technology? Polish some skill that I already have? Should I build something using my current skillset, or with some new technology? Should I put a website for my consultancy together to market myself? Should I do that using latest technology x, y, and z? Or should I just slap something up on Tumblr? I'm willing to do anything (moral) over the next 4 weeks to put myself into a position to maximize my income, and I'm open to all and every idea Programmers users may have. Let me hear them.

  • How to Convert HTML to PDF Using PHP?

    - by Meng Longlong
    PDF or Portable Document Format is a popular file type that is often used for online documents. It's great for distributing downloadable written content, and is frequently used by governments and businesses alike. Because it's a format that's familiar to all, many applications allow the user to convert other document types to the PDF format. PHP is one programming language that has a built-in ability to convert to PDF. PHP scripts can be used to transform file types such as HTML into PDF files.

  • Does searching documentation and samples look bad?

    I am starting a new job in a company with many developers and media people, the layout of the place is open with computers around a skinny oval, I have worked in small teams and programming embedded C, the jobis for objective C I'm still in a medium stage, so I know what I don't know (haha), that means I have to google it and then implement it, So the question is how bad does it look if the guy next to you does lot of searching for coding I mean, at the end of the day I will get the job done, but want to look professional too!

  • What are my tool options to prototype a 2D multiplayer game?

    - by Asher Einhorn
    I'm looking for the best tool to allow me to quickly put together a 2D game that relies largely on networking. It's extremely likely that this game will require a server side program to constantly run. I have little experience with these things and since it's a prototype i'd like the easiest options for achieving this. I am looking to make this game for the web and mobile devices, although at present I only have access to ios hardware, (no android etc). I just want to get the bare bones of this set up so I can test it from the earliest opportunity to see if it's fun.
