• What are the best code-less website design sites available?

  - by Ken Pespisa

  I'm looking for an alternative to www.squarespace.com. Squarespace is great, but leans slightly toward the social networking industry. I'm looking for a simple way to build Web sites for small businesses. The criteria is the following: Requires no programming knowledge. No software to download - all design and maintenance can be done via browser Has a good selection of templates and layouts Essentially I'm looking for the features within Typepad.com or WordPress.com, but instead of focusing around a blog it would help build a more traditional Web site.

• Ubuntu - connecting 3rd monitor fails with "xrandr: cannot find crtc for output DVI-0"

  - by MDCore

  I've got a laptop with a DVI and VGA output on the back. With everything connected it will only allow me to run 2 of the 3 monitors e.g. laptop display + VGA or DVI+VGA but not all 3. xrandr says I have 2 CRTC's, 0 and 1. The internet says I should be able to share a CRTC if the modeline is the same, and my 2 external monitors are the exact same make and model. How do I convince the software to drive all this hardware?

• The spork/platypus average: shameless self promotion

  - by Roger Hart

  This is the video of presentation I gave at UA Europe and TCUK this year. The actual sub-title was "Content strategy at Red Gate Software", but this heading feels more honest. For anybody who missed it, or is just vaguely interested, here's a link to me talking about de-suckifying the web. You can find the slideshare deck here, too* Watching it back is more than a little embarrassing, and makes me really, really want to do a follow up, so I can do three things: explain the rest of the big web project, now we've done it give some data on the outcome of the content review make a grovelling apology to our marketing guys, who I've been unfairly mean to in a childish effort to look cool There are a whole bunch of other TCUK presentations online, too. You can find them all here: http://tiny.cc/tcuk10_videos I'd particularly recommend Chris Atherton's: "Everything you always wanted to know about psychology and technical communication" - it's full of cool stuff. You should probably also watch David Black's opening keynote, which managed to make my hour of precocious grandstanding look measured, meek, and helpful. He actually makes some interesting points, but you'd basically have to ship Richard Dawkins off to Utah, if you wanted to go further out of your way to aggravate your audience. It does give an engaging account of running a large tech comms project, and raise some questions about how we propose to understand a world where increasing amounts of our stuff gets done by increasingly many increasingly complicated tissues of APIs. Well, sort of. That's what all the notes I made were about, anyway.   *Slideshare ate my fonts. Just so we're clear on this: I'd never use badly-kerned Arial in a presentation. Don't worry.

• I want to build a Virtual Machine, are there any good references?

  - by Michael Stum

  I'm looking to build a Virtual Machine as a platform independent way to run some game code (essentially scripting). The Virtual Machines that I'm aware of in games are rather old: Infocom's Z-Machine, LucasArts' SCUMM, id Software's Quake 3. As a .net Developer, I'm familiar with the CLR and looked into the CIL Instructions to get an overview of what you actually implement on a VM Level (vs. the language level). I've also dabbled a bit in 6502 Assembler during the last year. The thing is, now that I want¹ to implement one, I need to dig a bit deeper. I know that there are stack based and register based VMs, but I don't really know which one is better at what and if there are more or hybrid approaches. I need to deal with memory management, decide which low level types are part of the VM and need to understand why stuff like ldstr works the way it does. My only reference book (apart from the Z-Machine stuff) is the CLI Annotated Standard, but I wonder if there is a better, more general/fundamental lecture for VMs? Basically something like the Dragon Book, but for VMs? I'm aware of Donald Knuth's Art of Computer Programming which uses a register-based VM, but I'm not sure how applicable that series still is, especially since it's still unfinished? Clarification: The goal is to build a specialized VM. For example, Infocom's Z-Machine contains OpCodes for setting the Background Color or playing a sound. So I need to figure out how much goes into the VM as OpCodes vs. the compiler that takes a script (language TBD) and generates the bytecode from it, but for that I need to understand what I'm really doing. ¹ I know, modern technology would allow me to just interpret a high level scripting language on the fly. But where is the fun in that? :) It's also a bit hard to google because Virtual Machines is nowadays often associated with VMWare-type OS Virtualization...

• What to watch out for when writing code at an Interview?

  - by Philip

  Hi, I have read that at a lot of companies you have to write code at an interview. On the one hand I see that it makes sense to ask for a work sample. On the other hand: What kind of code do you expect to be written in 5 minutes? And what if they tell me "Write an algorithm that does this and that" but I cannot think of a smart solution or even write code that doesn't semantically work? I am particularly interested in that question because I do not have that much commercial programming experience, 2 years part-time, one year full-time. (But I am interested in programming languages since nearly 15 years though usually I was more concentrated in playing with the language rather than writing large applications...) And actually I consider my debugging and problem solving skills much better than my coding skills. I sometimes see myself not writing the most beautiful code when looking back, but on the other hand I often come up with solutions for hard problems. And I think I am very good at optimizing, fixing, restructuring existing code, but I have problems with writing new applications from scratch. The software design sucks... ;-) Therefore I don't feel comfortable when thinking about this code writing situation at an interview... So what do the interviewers expect? What kind of information about my code writing are they interested in? Philip

• C#/XNA get hardware mouse position

  - by Sunder

  I'm using C# and trying to get hardware mouse position. First thing I tryed was simple XNA functionality that is simple to use Vector2 position = new Vector2(Mouse.GetState().X, Mouse.GetState().Y); After that i do the drawing of mouse as well, and comparing to windows hardware mouse, this new mouse with xna provided coordinates is "slacking off". By that i mean, that it is behind by few frames. For example if game is runing at 600 fps, of curse it will be responsive, but at 60 fps software mouse delay is no longer acceptable. Therefore I tried using what I thought was a hardware mouse, [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool GetCursorPos(out POINT lpPoint); but the result was exactly the same. I also tried geting Windows form cursor, and that was a dead end as well - worked, but with the same delay. Messing around with xna functionality: GraphicsDeviceManager.SynchronizeWithVerticalRetrace = true/false Game.IsFixedTimeStep = true/fale did change the delay time for somewhat obvious reasons, but the bottom line is that regardless it still was behind default Windows mouse. I'v seen in some games, that they provide option for hardware acelerated mouse, and in others(I think) it is already by default. Can anyone give some lead on how to achieve that.

• Should I list this work experience on my resume? [closed]

  - by Phoenix

  I am currently working at a company. I did an internship before this job with a prestigious company and project itself was challenging but it was in the initial phases and hence there were no tight schedules and we ended up doing brainstorming for the first month and the 2nd month actually setting up our hardware, which is linux servers in lab and a cluster administrator for the servers. And then i wrote an addin task which runs on the server and uses existing API to collect some statistics from the the servers in the cluster and feeding them into another entity which is basically an algorithm that calculates how the load on the servers should be automatically balanced. Neither of these things went into production by the time I left the company and I'm not even sure of their current state. Does it make sense to include it in my resume then? I also worked as a software engineer right out of school at another prestigious company for 9 months. I was involved in some bug fixes before the product launched and I don't even recollect the exact fixes I made to the product. So, will it make sense to have these experiences on my resume ? Will people question me about them and will saying it was bug fixes and mentioning what kind of fixes suffice as enough to justify my work ex there ?

• Visual Studio 2010 Is Here!

  - by Bill Evjen

  I think back to the days of the first versions of Visual Studio (when it was called Visual Studio .NET, remember?) and I think about how far Microsoft has come with this IDE. It really is the best IDE on the market. There is so much to this IDE it is amazing. It now can really handle managing your complete software application development lifecycle. For me, it is (besides Windows 7) the best and most successful product Microsoft has developed. You can obviously get this now and it is available on MSDN and some other places: MSDN Visual Studio Trial Editions Visual Studio 2010 Express Editions (free) You will also find great info at the Visual Studio Developer Center. Some other interesting tidbits of info: JetBrain’s ReSharper 5.0 has been released for VS2010 Oracle will have the new Oracle Dev Tools for VS2010 within one month - http://bit.ly/9gC9NE Visual Studio 64-bit - Why there is no 64-bit version of VS - http://bit.ly/dhhwAj In installing this version of Visual Studio, if you have been working on the previous RC builds, then you are going to want to uninstall these previous editions of the 2010 product. You can do this through the Add Remove Programs dialog and you are going to want to select the appropriate item from the long list of Visual Studio items. You are then going to want to step through the Visual Studio dialog (it will seem as if you are installing it again) – and you will then come to a point where you can select the option to Uninstall the entire application. If you have installed the Silverlight 4 RC stuff, then you are also going to want to uninstall this and you are also going to want to uninstall the “Update for Visual Studio 2010 (KB976272)” before installing Silverlight RC2 – which you can find on www.silverlight.net.

• Microsoft Researchers shows off best Touch Screen ever made. Better than Apple touch screens!

  - by Gopinath

  All the touch devices we have in market today like iPads, iPhones, Samsung tablets and phones, etc.  have a very small issue – 100 milliseconds of lag. The lag is the amount of time a touch device takes to respond after you touch the device. The 100 milliseconds of lag may not be an issue when you are tapping and swapping the interface elements on a device, but they are apparent when you wing your finger around the screen faster. For example if you use any painting app, the lag is very obvious and screen responds slowly than an artist can paint with his finger. Researchers at Microsoft labs came out with a prototype of touch device that drastically cuts down the 100 milliseconds of lag time to just 1 millisecond. That’s 100 times faster than today’s touch screen devices. Check out the video embedded below for a demo of new touch screen. Over at TechCrunch, Chris Velazco says: The difference is staggering, especially when Dietz trots out the slow-motion footage. With the delay between touch input and screen response slashed by orders of magnitude, a device that sports the sort of super-low-latency Dietz envisions has the potential to feel far more (for lack of a better term) natural than its brethren. There’s zero delay when you slide a checker across a board, for example, and bringing that sort of instantaneous feedback to the many screens in our lives could help to bridge the gap between operating a bit of software and the feeling of interacting with objects.   It will be great boost to Microsoft’s tablet strategy if they succeed in bringing this research into mass market and allow it’s partners to use the technology on Windows 8 tablets.

• Are there mapping utilities out there that will let me import geo position data (lat/long) and plot the points on a map?

  - by GregH

  I have a data file with a bunch of lat/long positions. Is there any mapping software out there (google maps, etc) that will allow me to import the positions from the file and plot them on a map? I would be this can be done through google maps but I'm not sure how to do it. I just want something that I can use quickly with a minimal amount of programming to do. I don't need to annotate anything. Just view where the points are on the map. I'm just wondering if there is something already available out there to import into google maps.

• Confused about application submission

  - by snowflake

  I finished my app but I'm totally confused about how to submit it to launchpad and the software center. I'm also new to launchpad. 1) I created a project at launchpad and synchronized an OpenPGP key via the password tool. This was about 30 minutes ago but launchpad still shows "No OpenPGP keys registered." Is this normal? 2) What I have to do next with the PPA? 3) How do I submit my app? Do I have to adjust files with the PPA? The showdown blog shows that quickly submitubuntu is enough but here in the forum I read about quickly release or quickly share. So which one is correct? 4) Do I have to add this file to launchpad as well? 5) Do I get a confirmation that my app was correctly submitted and take part of the contest? Since I do it for first time I want to be sure that everything is ok. I'm sorry for all my questions and I know that there are many topics about it but everywhere something different is written and I'm confused how to proceed. Thanks in advance!

• Wireless printer going offline upon entering power save mode

  - by Regmi

  I recently bought a printer, Samsung ML1865W, a wireless laser printer. It works very well, wirelessly until after a while, it goes to power save mode when the printer goes offline. I then cannot connect to the printer (pinging the ip and various ports associated with it do not give any response) until I power cycle the printer. I have checked my wireless settings and my router, I have installed the printer software in WinXP, Win2000 and in Mac and the printer behaves just the same. Any ideas if the printer hardware itself is broken or that its something on my network/application side that's the culprit. If you own the printer, have you had any trouble like that at any time?

• How do I choose which Ethernet Adapter to bridge in VMPlayer

  - by Catherine MacInnes

  I am running vmplayer 3.1.0 on Ubuntu. The host machine has four ethernet adapters that are configured to run on four different subnets. I need to run four VMs each with a single ethernet adapter bridged onto a specific one of the physical ethernet adapters. Does anyone know how to do this? Am I simply exceeding the capabilities of vmplayer and have to go to one of the other vmware products, if so, which one. Note that I have no need to create additional VMs, these are VMs that are being given to me by companies that want us to develop software for their products.

• Postfix sendmail -f configuration

  - by William

  I have Postfix installed on two servers. One of them writes e-mail (satellite) and the other one delivers the e-mails (smarthost). When I write e-mail from the satellite server I'm using the sendmail command. My problem is that when e-mail arrives the Return-Path is set to the user@hostname where user is the user that is running sendmail and hostname is the servers hostname. If I use the parameter -f with sendmail I change that, but I'm hoping there is a way to do it in a configuration file for Postfix. Is this possible or should I just deal with having to configure all my software to add the -f argument? Thanks in advanced.

• Online betting system design [closed]

  - by Rafal

  I am a Computer Science student, preparing for my exam in software engineering. I am strugging with answering one of the sample questions to the scenario below. My understanding is that the system design approach should probably be a mixture of agile and plan driven elements but - since I've no practical experience - it's hard for me to decide on the balance and tolls that should be used. I will appreciate any hints from experienced business analysts who were involved in similar kind of projects. Ray Sing is the owner of “Last Betz", a bookmakers with 7 outlets across Louth and Meath. With the advent of smartphones Ray would now like to allow his clients to place their bets online using their mobile devices. Clients would register for an account and password and would log their credit card details via the Last Betz website. To begin using the facility customers must 'load' their accounts with 100 euros. Any winnings, minus commission, will be placed in the account whilst any losses will be automatically deducted from the account. Assuming you have been selected to develop the above system: How would you approach the design of this system? Discuss the design methods and models you would use.

• Install proprietary drivers 14.04 NVIDIA (steam segmentation issue)

  - by allthosemiles

  Recently, I finally got the official drivers for my NVIDIA 560 Ti card installed on Ubuntu 14.04 (hooray) However I started looking into installing Steam and I'm getting segmentation errors when I try to run the software. I tried installing 32-bit libs and it seemed like they weren't available or they were already installed. Upon further investigation, I found that a solution is to install the proprietary drivers, install steam then switch back to the other drivers. I'm not really sure what "proprietary drivers" are in all honesty. Has anyone gone through this process that could provide some insight here? (I installed the official 64-bit driver from the NVIDIA site for my 560 Ti just for reference. And the Ubuntu version installed is 64-bit as well) Update: This is the error text I get when trying to run steam after installing it via the ubuntu store.

  Background Looking to leverage an existing GIS system for exploring organizational data. Architecture The following figure represents a high-level overview of the system's desired features: The most basic usage would be as follows: The user visits a web site. The system presents a map (having regions, cities, and buildings). The user drills-down on the map to a particular building. The system provides a basic CRUD interface. The user can view and modify information about personnel (e.g., their assigned teams), equipment (e.g., network appliances), applications, and the building itself (e.g., contact and phone numbers). Ideally, all the components should be open-source (or otherwise free). Problem This must be a small project that needs a quick (but functional) prototype, mostly to confirm whether or not such a system would be useful in the long term. Questions What software components would you use to quickly develop a working prototype? What open-source solutions already exist, if any? Ideas Here is what I am thinking: PostGIS - Define the regions, cities, and sites Google Maps - Display an interactive, clickable map geoJSON - Protocol between PostGIS and Google Maps Seam - CRUD interface Custom Development For example, this would entail: Installation and configuration Configure SSH for remote logins Subversion (or git) PostgreSQL PostGIS Java Tomcat Seam JasperReports Enter GIS information into PostGIS Aggregate data sources into PostgreSQL database Develop starting page for map interface Develop clickable Google Maps interface Develop summary reports Develop CRUD interface using Seam for data maintenance Surely something like this already exists? Thank you!

• Acceptable sound quality: stereo needed for an Android game?

  - by Thomas Calc

  I have various simple short sound effects (damage sound, dying sound, thunderbolt, fanfare, breaking) for a game that is developed for Android currently. I use OGG files: 96kbps VBR, 44.1KHz, 2 channels (that means stereo, right?). I read the other stackexchange topics about "acceptable sound quality", but they're too general, address too many things. My experience is that even with 80kbps, my effects sound OK. But I tested it on a limited number of Android devices (including a Sony Ericsson Xperia Neo and a HTC Desire HD). My questions: For mobile phones and tablets, generally, what parameters are recommended? Won't my 80kbps sounds be bad on a newer device (such as a modern tablet)? I don't hear any difference between stereo and mono (2 channels vs. 1 channel, right?), is there any noticeable difference at all for mobile phones / tablets? (in terms of the player experience) May it worth it at all? I assume that stereo sounds take much more in memory (when they're decoded to PCM), despite of the fact that the compressed OGG size is practically the same. Reacting to Roy T.'s great comment: Actually, I couldn't measure the PCM size (Android decodes OGG internally), but I thought that stereo will take more space than mono when uncompressed After throwing out one of the WAV channels in Audacity, and re-exporting it: The new WAV file size is half than before The OGG file size is practically the same as before The sound effects and game music was recorded by my friend who is an experienced hobby musician/composer, but he knows little about computers & software so he just gave me some high-quality WAV files generated via his hardware.These were stereo, but if I check them in Audacity, both channels appear to be exactly the same.Can I consider them the same (= moving to mono), or might there be some unnoticeable differences to the human eye?

• Geek Chess: Nixie Tubes as Board Pieces [Video]

  - by Jason Fitzpatrick

  We’ve seen some geeky chessboards in our day, but this board is a masterpiece of geekiness. Check out the video to see the Nixie tubes in action. Courtesy of a tinker named Tony, we find this delightfully analog and geeky chess set. He writes: This developed as a spinoff from the hardware and controllers I’m designing for a range of nixie clocks and watches as a ‘simple’ project that wouldn’t need much software to complete it. All visible parts are made from materials contemporary with Nixie technology and no modern plastics or resins are used anywhere in its’ consruction (other than the electronic components and PCBs). The board and pieces are machined from phenolic resin laminate and assembled using brass fittings. The brown base pieces have been filled and wiped with gold and silver engravers wax, giving a ‘worn gilding’ appearance. The displays are ex-Soviet Nixie gas display tubes, manufactured in the early 1980s.

• How should I isolate computers with different roles on a network

  - by fishhead

  I work in an industrial plant and we have one network(physical wire) that us used for both office usage and for process systems. The office computers are only used for typical office needs but occasionally do connect to the process computers to obtain information from a sql server or for some other purpose. A new initiative is in the works and is rolling down hill from corporate and that is to standardize how the the computers are used at work and they would be severely locked down and only a standard set of applications will be allowed to execute. one of the requirements is to also have non office computers isolated from the company domain. our non-office computers are a mix of Man-Machine interfaces and sql-servers all running software that non standard. My question is, how can we divorce the control systems computers from the company domain but still have access to the servers from the company domain. thanks
