• Does waterfall require code complete before QA steps in?

  - by P.Brian.Mackey

  The process used at a certain company consists of: Create a layout according to some designs made in a web page design tool. (CSS, html) Requirements come in with "functional requirements". These consist of 100's of lines of business directions. E.G. Create a Table on page X. Column1 has numeric data. Column1 is the client code. Column2 is a string...etc. Write code to meet all functional requirements. When all code is checked in, send to QA (which is the BA that wrote the requirements) for inspection, bug finds and change requests. Punt back to developer with a list of X bugs and Y change requests. While bug finds or change requests 0 go to step 4. The agile development environments I have worked in allow, if not demand, early QA inspection and early user acceptance. So, pieces of the program can be refined and redefined before the entire application is in place. Not only that, but the process leaves little room for error or people changing their minds. Instead, those "change requests" come in at the last stage when they do the most damage. And being that a bug-fix's cost increases over time, this is a costly way to write code. I am no waterfall expert. As described, is this waterfall being mishandled in some way? How does waterfall address my concerns?

• Google Rolls Out a New and Compact Navigation Bar

  - by Jason Fitzpatrick

  Earlier this spring Google introduced the black navigation bar; now they’ve updated the bar to take up less space and be more useful. Although the black bar is useful in-so-far as it gives you quick access to Google services (useful, of course, only if you use those services) the new navigation bar–seen in the video above–includes an improved layout. Rather than use the bar space to spread out links which the user may or may not use the service links are now tucked into a mouse-over menu accessed by hovering on the Google logo. The majority of the space previously just taken up by links and the black bar itself is now a a search box. If you don’t already see the new interface, look for it to appear in your Google account within the next few days. Hit up the link below to read the official announcement.

• What are the boundaries between the responsibilities of a web designer and a web developer?

  - by Beofett

  I have been hired to do functional development for several web site redesigns. The company I work for has a relatively low technical level, and the previous development of the web sites were completed by a graphic designer who is self taught as far as web development is concerned. My responsibilities have extended beyond basic development, as I have been also tasked with creating the development environment, and migrating hosting from external CMS hosting to internal servers incorporating scripting languages (I opted for PHP/MySQL). I am working with the graphic designer, and he is responsible for the creative design of the web. We are running into a bit of friction over confusion between the boundaries of our respective tasks. For example, we had some differences of opinion on navigation. I was primarily concerned with ease-of-use (the majority of our userbase are not particularly web-savvy), as well as meeting W3 WAI standards (many of our users are older, and we have a higher than average proportion of users with visual impairment). His sole concern was what looked best for the website, and I felt that the direction he was pushing for caused some functional problems. I feel color choices, images, fonts, etc. are clearly his responsibility, and my expectation was that he would simply provide me with the CSS pages and style classes and IDs to use, but some elements of page layout also seem to fall more under the realm of "usability", which to me translates as near-synonymous with "functionality". I've been tasked with selecting the tools we'll use, which include frameworks, scripting languages, database design, and some open source applications (Moodle for example, and quite probably Drupal in the future). While these tools are quite customizable, working directly with some of the interfaces is beyond his familiarity with CSS, HTML, and PHP. This limits how much direct control he has over the appearance, which has lead to some discussion about the tool choices. Is there a generally accepted dividing line between the roles of a web designer and a web developer? Does his relatively inexperienced background in web technologies influence that dividing line?

• Apache Server-Side Includes Refuse to Work (Tried everything in the docs but still no joy)

  Trying to get apache server-side includes to work. Really simple - just want to include a footer on each page.

Tried file=, also with/without absolute path. Is there something else I'm missing? I see the same thing on another unrelated server (more or less stock CentOS 6), so I suspect the problem is between keyboard and chair...

• How Do I Print Photos?

  - by Takkat

  Other than for Windows in Ubuntu there are no fancy utilities provided from printer manufacturers to print photos. I am aware of Gnome Photo Printer and of Photoprint, the first being easy to handle, the latter having more options. However I wonder if there are any other or maybe even better alternatives (including plugins) to perform the following tasks: Print photos in the best photo-resolution the driver offers Adjust paper size for standard values of photo papers Choose paper tray if the printer has more than one Print out multiple photos on one page including mixed sizes (grids) Multiple prints with same settings Borderless printing if the printer is capable of this Any additional options like pre-processing for color correction or noise reduction would be nice to have but are not so essential. Update According to this spec it seems not to so easy to accomplish the simple task of printing photos. Indeed all applications I have gone through have major drawbacks that make printing photos almost impossible. Below I will list what put me off using them for photo printing: Gnome Photo Printer: no thumbnails, no grids Photoprint: does not keep settings, GUI broken, no standard photo size, no thumbs Eye Of Gnome: no multiple pages, no grids Gimp + Images Grid Layout: far too many steps to finally find that prints are always different to their previews. F-Spot: no grids Picasa 3: no grids, very few fixed paper sizes, 300 dpi only flPhoto: strange GUI, no thumbs, no printer settings, did not print at all Windows: Ooops - everything works fine! But I want Ubuntu to do this! After half a pack of ink cartridges and half a pack of photo paper cards I am getting tired of testing. At least Gimp and Picasa looked promising but both don't keep their promise when it comes to printing. I'd already be happy to quickly print a few photos with EOG if bug #80220 was fixed - but it's still on "wishlist".

• What You Said: How Do You Sync Your Files Between Your Devices?

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your tricks and techniques for keeping files synced between your different devices. Now we’re back to highlight how you do it. Overwhelmingly, you do it with Dropbox. Despite the proliferation of different platforms there has been little inroads made into any sort of universal syncing. We heard from quite a few different readers and by far the most popular option was to use Dropbox to ensure that you could get the music and documents you wanted whether you were on your desktop, laptop, netbook, iPhone, or Android device. In the same breath however, nearly all of your added on an additional service. The real message, it would seem, is that there simply isn’t a service good enough to meet all of the needs most users have, all of the time. The most common response to our Ask the Readers question was “Dropbox and…”; this pattern is illustrated nicely in the following quotes. Kim writes: Dropbox for all kinds of things. (Would also use Sugarsync, but it doesn’t support Linux.) Lastpass for passwords. Xmarks for bookmarks, although I’m going to try Firefox Sync soon. Evernote for things like shell commands I might want someday. Google Beta for music, once I get it uploaded. I have an Amazon account too, but Google gives you more space. Gmail. Michael finds himself in a similar situation and writes: How to Make and Install an Electric Outlet in a Cabinet or DeskHow To Recover After Your Email Password Is CompromisedHow to Clean Your Filthy Keyboard in the Dishwasher (Without Ruining it)

• Start Debugging in Visual Studio

  - by Daniel Moth

  Every developer is familiar with hitting F5 and debugging their application, which starts their app with the Visual Studio debugger attached from the start (instead of attaching later). This is one way to achieve step 1 of the Live Debugging process. Hitting F5, F11, Ctrl+F10 and the other ways to start the process under the debugger is covered in this MSDN "How To". The way you configure the debugging experience, before you hit F5, is by selecting the "Project" and then the "Properties" menu (Alt+F7 on my keyboard bindings). Dependent on your project type there are different options, but if you browse to the Debug (or Debugging) node in the properties page you'll have a way to select local or remote machine debugging, what debug engines to use, command line arguments to use during debugging etc. Currently the .NET and C++ project systems are different, but one would hope that one day they would be unified to use the same mechanism and UI (I don't work on that product team so I have no knowledge of whether that is a goal or if it will ever happen). Personally I like the C++ one better, here is what it looks like (and it is described on this MSDN page): If you were following along in the "Attach to Process" blog post, the equivalent to the "Select Code Type" dialog is the "Debugger Type" dropdown: that is how you change the debug engine. Some of the debugger properties options appear on the standard toolbar in VS. With Visual Studio 11, the Debug Type option has been added to the toolbar If you don't see that in your installation, customize the toolbar to show it - VS 11 tends to be conservative in what you see by default, especially for the non-C++ Visual Studio profiles. Comments about this post by Daniel Moth welcome at the original blog.

• C# XNA: Effecient mesh building algorithm for voxel based terrain ("top" outside layer only, non-destructible)

  - by Tim Hatch

  To put this bluntly, for non-destructible/non-constructible voxel style terrain, are generated meshes handled much better than instancing? Is there another method to achieve millions of visible quad faces per scene with ease? If generated meshes per chunk is the way to go, what kind of algorithm might I want to use based on only EVER needing the outer layer rendered? I'm using 3D Perlin Noise for terrain generation (for overhangs/caves/etc). The layout is fantastic, but even for around 20k visible faces, it's quite slow using instancing (whether it's one big draw call or multiple smaller chunks). I've simplified it to the point of removing non-visible cubes and only having the top faces of my cube-like terrain be rendered, but with 20k quad instances, it's still pretty sluggish (30fps on my machine). My goal is for the world to be made using quite small cubes. Where multiple games (IE: Minecraft) have the player 1x1 cube in width/length and 2 high, I'm shooting for 6x6 width/length and 9 high. With a lot of advantages as far as gameplay goes, it also means I could quite easily have a single scene with millions of truly visible quads. So, I have been trying to look into changing my method from instancing to mesh generation on a chunk by chunk basis. Do video cards handle this type of processing better than separate quads/cubes through instancing? What kind of existing algorithms should I be looking into? I've seen references to marching cubes a few times now, but I haven't spent much time investigating it since I don't know if it's the better route for my situation or not. I'm also starting to doubt my need of using 3D Perlin noise for terrain generation since I won't want the kind of depth it would seem best at. I just like the idea of overhangs and occasional cave-like structures, but could find no better 'surface only' algorithms to cover that. If anyone has any better suggestions there, feel free to throw them at me too. Thanks, Mythics

• How to set acpi=off for installation?

  - by Johan Helgø

  I'm trying to install Ubuntu 12.04 LTS 64bit from a USB created in Windows using the recommended software from pendrivelinux. The USB is tested on two laptops and works fine. The install does not work on my desktop PC, it either hangs with lots of text on the screen, or it just gives me a screen with garbled colors. Right now it hangs on "[3.925311] Initializing USB Mass Storage driver...", but it hangs on different spots every time I try. I know that acpi=off will fix this. On older versions, there used to be a pink screen with the icon of a keyboard, at that screen I could press ESC, and I would then get a long list of languages, I could choose English, and then I would get options for setting acpi=off, then install without any problems. This new install menu does not have those options. The (now black and white) "Installer boot menu"'s advanced options is blank. There simply are no advanced options. If I go to help, then press F6, I get to a help screen describing the different boot parameters. I see examples of writing "Install acpi=off" However, writing "install acpi=off" it gives an error saying "could not find kernel image: install". How can I install Ubuntu 12.04 with acpi=off? (Oh, btw, nothing happens if I press F6 in the "Installer boot menu")

• AutoHotkey cannot interact with Windows 8 Windows&hellip;or can it!

  - by deadlydog

  If you’ve installed Windows 8 and are trying to use AutoHotkey (AHK) to interact with some of the Winodws 8 Windows (such as the Control Panel for example), or with apps that need to be Ran As Administrator, then you’ve likely become very frustrated as I did to discover that AHK can not send any commands (keyboard or mouse input) to these windows.  This was a huge concern as I often need to run Visual Studio as an administrator and wanted my hotkeys and hotstrings to work in Visual Studio.  After a day of fighting I finally realized the answer (and it’s pretty obvious once you think about it).  If you want AHK to be able to interact with Windows 8 Windows or apps running as administrator, then you also need to have your AHK script Run As Administrator. If you are like me then you probably have your AHK scripts set to run automatically at login, which means you don’t have the opportunity to right-click on the script and manually tell it to Run As Administrator.  Luckily the work around is simple.  First, if you want to have your AHK script (or any program for that matter) run when you log in, create a shortcut to the application and place the shortcut in: C:\Users\[User Name]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup Note that you will need to replace “[User Name]” with your username, and that “AppData” is a hidden folder so you’ll need to turn on viewing hidden folders to see it.  So by placing that shortcut there Windows will automatically run your script when you log on.  Now, to get it to run as an administrator by default, right-click on the shortcut and go to Properties.  Under the Shortcut tab, click on the “Advanced…” button and check off “Run as administrator”.  That’s it.  Now when you log onto Windows your script will automatically start up, running as an administrator; allowing it to interact with any application and window like you had expected it to in the first place.   Happy coding!

• Is an ACPI GPE storm normal in an Ubuntu session?

  - by Tinellus

  In a previous question (What is a an ACPI GPE storm?), I asked about ACPI GPE storm. Looking closer to my kern.log file in /var/log/, I notice that in every session at some point (usually withing 20' after startup) a GPE storm is triggered. When I open kern.log immediately after startup, I see that the 'GPE-storm' can be triggered by anything (a copy-action, the opening of an app like Firefox or Thunderbird, etc...). This worries me. Looking for other ACPI related events in kern.log, I find these error messages. I hope someone can give some advice: Jun 10 16:33:20 Guy-VAIO kernel: [ 0.724505] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it Jun 10 16:33:20 Guy-VAIO kernel: [ 0.795205] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored Jun 10 16:33:20 Guy-VAIO kernel: [ 1.024009] ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared Jun 10 16:33:20 Guy-VAIO kernel: [ 23.140259] [Firmware Bug]: ACPI(VGA) defines _DOD but not _DOS There's also a video driver message that worries me, don't know if it's related though: Jun 10 16:33:20 Guy-VAIO kernel: [ 23.162154] fglrx: module license 'Proprietary.

• Need assistance matching a general theme style as well as eCommerce capability

  - by humble_coder

  I'm in the process of acquiring a new design client. They are getting into the business of "auto parts wholesaling" and they want a storefront. My preference is/was to create something from scratch. However, here is an established trend in their particular market (similar parts, layout, etc). They insist on following the existing visual trend, as per the following: http://www.xtremediesel.com/ http://www.thoroughbreddiesel.com/ http://www.alligatorperformance.com/ My plan of attack at this point is to find a comparable WP theme and a flexible (but useful) backend/product management. Their current demo site (which their previous developer made a stab at) is using Pinnacle Cart. It is no where near what they need, nor is it intuitive to work with. I was actually considering Magento for its greater abilities but I'm still considering options. That said, my two primary dilemmas are as follows: 1) I need a theme that mimics the general style of those listed. They explicitly said they didn't want anything too clean (e.g. ThemeForest, Woothemes) as it "wasn't rugged or busy looking enough" for their field. 2) I need a WP/Magento/WP e-Commerce (or any one of a host of other) plugin that will allow for bulk import/update of nearly 200,000 products, descriptions and images. I'm not opposed to manually interfacing with the DB for import, but in the end, I need a store/system that doesn't needlessly add 50 tables to accommodate some "wet behind the ears" concept of table normalization and is easy to add to. Anyway, if anyone has any quality suggestions regarding either of these issues, it would be most appreciated. Best.

• Metro: Dynamically Switching Templates with a WinJS ListView

  - by Stephen.Walther

  Imagine that you want to display a list of products using the WinJS ListView control. Imagine, furthermore, that you want to use different templates to display different products. In particular, when a product is on sale, you want to display the product using a special “On Sale” template. In this blog entry, I explain how you can switch templates dynamically when displaying items with a ListView control. In other words, you learn how to use more than one template when displaying items with a ListView control. Creating the Data Source Let’s start by creating the data source for the ListView. Nothing special here – our data source is a list of products. Two of the products, Oranges and Apples, are on sale. (function () { "use strict"; var products = new WinJS.Binding.List([ { name: "Milk", price: 2.44 }, { name: "Oranges", price: 1.99, onSale: true }, { name: "Wine", price: 8.55 }, { name: "Apples", price: 2.44, onSale: true }, { name: "Steak", price: 1.99 }, { name: "Eggs", price: 2.44 }, { name: "Mushrooms", price: 1.99 }, { name: "Yogurt", price: 2.44 }, { name: "Soup", price: 1.99 }, { name: "Cereal", price: 2.44 }, { name: "Pepsi", price: 1.99 } ]); WinJS.Namespace.define("ListViewDemos", { products: products }); })(); The file above is saved with the name products.js and referenced by the default.html page described below. Declaring the Templates and ListView Control Next, we need to declare the ListView control and the two Template controls which we will use to display template items. The markup below appears in the default.html file: <!-- Templates --> <div id="productItemTemplate" data-win-control="WinJS.Binding.Template"> <div class="product"> <span data-win-bind="innerText:name"></span> <span data-win-bind="innerText:price"></span> </div> </div> <div id="productOnSaleTemplate" data-win-control="WinJS.Binding.Template"> <div class="product onSale"> <span data-win-bind="innerText:name"></span> <span data-win-bind="innerText:price"></span> (On Sale!) </div> </div> <!-- ListView --> <div id="productsListView" data-win-control="WinJS.UI.ListView" data-win-options="{ itemDataSource: ListViewDemos.products.dataSource, layout: { type: WinJS.UI.ListLayout } }"> </div> In the markup above, two Template controls are declared. The first template is used when rendering a normal product and the second template is used when rendering a product which is on sale. The second template, unlike the first template, includes the text “(On Sale!)”. The ListView control is bound to the data source which we created in the previous section. The ListView itemDataSource property is set to the value ListViewDemos.products.dataSource. Notice that we do not set the ListView itemTemplate property. We set this property in the default.js file. Switching Between Templates All of the magic happens in the default.js file. The default.js file contains the JavaScript code used to switch templates dynamically. Here’s the entire contents of the default.js file: (function () { "use strict"; var app = WinJS.Application; app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { WinJS.UI.processAll().then(function () { var productsListView = document.getElementById("productsListView"); productsListView.winControl.itemTemplate = itemTemplateFunction; });; } }; function itemTemplateFunction(itemPromise) { return itemPromise.then(function (item) { // Select either normal product template or on sale template var itemTemplate = document.getElementById("productItemTemplate"); if (item.data.onSale) { itemTemplate = document.getElementById("productOnSaleTemplate"); }; // Render selected template to DIV container var container = document.createElement("div"); itemTemplate.winControl.render(item.data, container); return container; }); } app.start(); })(); In the code above, a function is assigned to the ListView itemTemplate property with the following line of code: productsListView.winControl.itemTemplate = itemTemplateFunction;   The itemTemplateFunction returns a DOM element which is used for the template item. Depending on the value of the product onSale property, the DOM element is generated from either the productItemTemplate or the productOnSaleTemplate template. Using Binding Converters instead of Multiple Templates In the previous sections, I explained how you can use different templates to render normal products and on sale products. There is an alternative approach to displaying different markup for normal products and on sale products. Instead of creating two templates, you can create a single template which contains separate DIV elements for a normal product and an on sale product. The following default.html file contains a single item template and a ListView control bound to the template. <!-- Template --> <div id="productItemTemplate" data-win-control="WinJS.Binding.Template"> <div class="product" data-win-bind="style.display: onSale ListViewDemos.displayNormalProduct"> <span data-win-bind="innerText:name"></span> <span data-win-bind="innerText:price"></span> </div> <div class="product onSale" data-win-bind="style.display: onSale ListViewDemos.displayOnSaleProduct"> <span data-win-bind="innerText:name"></span> <span data-win-bind="innerText:price"></span> (On Sale!) </div> </div> <!-- ListView --> <div id="productsListView" data-win-control="WinJS.UI.ListView" data-win-options="{ itemDataSource: ListViewDemos.products.dataSource, itemTemplate: select('#productItemTemplate'), layout: { type: WinJS.UI.ListLayout } }"> </div> The first DIV element is used to render a normal product: <div class="product" data-win-bind="style.display: onSale ListViewDemos.displayNormalProduct"> <span data-win-bind="innerText:name"></span> <span data-win-bind="innerText:price"></span> </div> The second DIV element is used to render an “on sale” product: <div class="product onSale" data-win-bind="style.display: onSale ListViewDemos.displayOnSaleProduct"> <span data-win-bind="innerText:name"></span> <span data-win-bind="innerText:price"></span> (On Sale!) </div> Notice that both templates include a data-win-bind attribute. These data-win-bind attributes are used to show the “normal” template when a product is not on sale and show the “on sale” template when a product is on sale. These attributes set the Cascading Style Sheet display attribute to either “none” or “block”. The data-win-bind attributes take advantage of binding converters. The binding converters are defined in the default.js file: (function () { "use strict"; var app = WinJS.Application; app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { WinJS.UI.processAll(); } }; WinJS.Namespace.define("ListViewDemos", { displayNormalProduct: WinJS.Binding.converter(function (onSale) { return onSale ? "none" : "block"; }), displayOnSaleProduct: WinJS.Binding.converter(function (onSale) { return onSale ? "block" : "none"; }) }); app.start(); })(); The ListViewDemos.displayNormalProduct binding converter converts the value true or false to the value “none” or “block”. The ListViewDemos.displayOnSaleProduct binding converter does the opposite; it converts the value true or false to the value “block” or “none” (Sadly, you cannot simply place a NOT operator before the onSale property in the binding expression – you need to create both converters). The end result is that you can display different markup depending on the value of the product onSale property. Either the contents of the first or second DIV element are displayed: Summary In this blog entry, I’ve explored two approaches to displaying different markup in a ListView depending on the value of a data item property. The bulk of this blog entry was devoted to explaining how you can assign a function to the ListView itemTemplate property which returns different templates. We created both a productItemTemplate and productOnSaleTemplate and displayed both templates with the same ListView control. We also discussed how you can create a single template and display different markup by using binding converters. The binding converters are used to set a DIV element’s display property to either “none” or “block”. We created a binding converter which displays normal products and a binding converter which displays “on sale” products.

• Black Screen after Resume from Sleep (Kubuntu)

  - by user20271

  I know there is a lot of other posts like this, but I have been looking for hours and I still haven't found any solution. I have recently installed Kubuntu Linux along side my Windows 7, the sleep on my Win7 works fine and resumes like normal. When I am loaded into Kubuntu, and I put my laptop to sleep, it goes into sleep as normal. When I go to RESUME from the sleep, the screen stays solid black, it doesn't light up, no blinking curser or anything. The Wi-Fi light is 'off' (orange) and I cannot turn it on. The Caps lock and the Num lock lights on the keyboard blink slowly. I hear something on the inside of the computer start to spin. I am not very experienced with Kubuntu/Linux, but I do know a bunch of computer terminology, I am still far from an expert though. I have about 300GB designated to my Win7 stuff, and another partition with about 100GB for my Kubuntu Linux. My computers specs are as follows: Windows 7 64-bit I have the most recent version of Kubuntu because I just downloaded it a few days ago and updated it yesterday. AMD Athlon Duel-Core processor 4GB of RAM And it is a HP G61 Laptop

• What are the packages/libraries I should install before compiling Python from source?

  - by Lennart Regebro

  Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). This is the list I compiled with below help and by digging in setup.py. It is complete for Ubuntu 10.04 and 11.04 at least: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) libncursesw5-dev libssl-dev libgdbm-dev libsqlite3-dev libbz2-dev More optional: tk-dev libdb-dev Ubuntu has no packages for v1.8.5 of the Berkeley database, nor (for obvious reasons) the Sun audio hardware, so the bsddb185 and sunaudiodev modules will still not be built on Ubuntu, but all other modules are built with the above packages installed. Python 2.5 and Python 2.6 also needs to have LDFLAGS set on Ubuntu 11.04 and later, to handle the new multi-arch layout: export LDFLAGS="-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)" For Python 2.6 and 2.7 you also need to explicitly enable SSL after running the ./configure script and before running make. In Modules/Setup there are lines like this: #SSL=/usr/local/ssl #_ssl _ssl.c \ # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ # -L$(SSL)/lib -lssl -lcrypto Uncomment these lines and change the SSL variable to /usr: SSL=/usr _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto Python 2.6 also needs Modules/_ssl.c modified to be used with OpenSSL 1.0, which is used in Ubuntu 11.10. At around line 300 you'll find this: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ Change that into: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ #ifndef OPENSSL_NO_SSL2 else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ #endif else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ This disables SSL_v2 support, which apparently is gone in OpenSSL1.0.

• Run a startup script with lightdm

  - by cheshirekow

  I have a tablet PC and the graphics driver doesn't support xrandr, so in order to rotate the screen I run a script which changes the Xorg.conf file and then restarts lightdm. I also have a script which uses xsetwacom and xinput to change the rotation of the input devices so that the match the new orientation. I've learned how to get the script to run when I login, but I'd like it to run before I login, so that I don't have to enable auto-login with lightdm. I do need it to run though, or the input (touch and pen) is rotated with respect to the screen, so that when I touch the screen the input is in a completely different area, making it really difficult to use the onscreen keyboard. I've looked at other questions on this site. I've tried putting my script in /etc/Xsession.d but that didn't seem to work. I also tried putting it in /etc/rc.local but I think that is the wrong place, nothing seems to happen. I've also tried googling for lightm script hooks, and various other google terms. Any suggestions? Edit 1: After doing some research, it seems to me that it might not be that I want to run a script with lightdm, but rather with the lighdm greeter (in this case, I think the unity-greeter?). Are there any script-hooks for the unity-greeter?

• Semantic Form Markup for Yes or No Questions - Or Should I Tell my Designers to Bugger Off?

  - by sholsinger

  I frequently receive mock-ups of HTML forms with the following prototype: Some long winded yes or no question?   (o) Yes   ( ) No The (o) and ( ) in this prototype represent radio buttons. My personal view is that if the question has only a true or false value then it should be a check box. That said, I have seen this sort of "layout" from almost every designer I've ever worked with. If I were not to question their decision, or question the client's decision, I'd probably mark it up like this: <p class="pseudo_label">Some long winded yes or no question?</p> <input type="radio" name="the_question" id="the_question_yes" value="1"> <label for="the_question_yes" class="after_radio">Yes</label> <input type="radio" name="the_question" id="the_question_no" value="0"> <label for="the_question_no" class="after_radio">No</label> I really don't want to do that. I want to push back and convince them that this should really be a check box and not two radio buttons. But my question is, if I can't convince them – you're welcome to help me try – how should I code that original design requirement such that it is semantic and at least understandable for screen reader users? If I were able to convince my tormentors to change their minds, I would likely code it in the following fashion: <label for="the_question">Some long winded yes or no question?</label> <input type="checkbox" name="the_question" id="the_question" value="1"> What do you think about this issue? Should I push back? Possibly more importantly is either way semantically correct?

• How do you avoid jumping to a solution when under pressure? [closed]

  - by GlenPeterson

  When under a particularly strict programming deadline (like an hour), if I panic at all, my tendency is to jump into coding without a real plan and hope I figure it out as I go along. Given enough time, this can work, but in an interview it's been pretty unsuccessful, if not downright counter-productive. I'm not always comfortable sitting there thinking while the clock ticks away. Is there a checklist or are there techniques to recognize when you understand the problem well enough to start coding? Maybe don't touch the keyboard for the first 5-10 minutes of the problem? At what point do you give up and code a brute-force solution with the hope of reasoning out a better solution later? A related follow-up question might be, "How do you ensure that you are solving the right problem?" Or "When is it most productive to think and design more vs. code some experiments to and figure out the design later?" EDIT: One close vote already, but I'm not sure why. I wrote this in the first person, but I doubt I'm the only programmer to ever choke in an interview. Here is a list of techniques for taking a math test and another for taking an oral exam. Maybe I'm not expressing myself well, but I'm asking if there is a similar list of techniques for handling a programming problem under pressure?
