• Acer aspire 5735z wireless not working after upgrade to 11.10

  - by Jon

  I cant get my wifi card to work at all after upgrading to 11.10 Oneiric. I'm not sure where to start to fix this. Ive tried using the additional drivers tool but this shows that no additional drivers are needed. Before my upgrade I had a drivers working for the Rt2860 chipset. Any help on this would be much appreciated.... thanks Jon jon@ubuntu:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:1d:72:ec:76:d5 inet addr:192.168.1.134 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::21d:72ff:feec:76d5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7846 errors:0 dropped:0 overruns:0 frame:0 TX packets:7213 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8046624 (8.0 MB) TX bytes:1329442 (1.3 MB) Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:91 errors:0 dropped:0 overruns:0 frame:0 TX packets:91 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:34497 (34.4 KB) TX bytes:34497 (34.4 KB) Ive included by dmesg output below [ 0.428818] NET: Registered protocol family 2 [ 0.429003] IP route cache hash table entries: 131072 (order: 8, 1048576 bytes) [ 0.430562] TCP established hash table entries: 524288 (order: 11, 8388608 bytes) [ 0.436614] TCP bind hash table entries: 65536 (order: 8, 1048576 bytes) [ 0.437409] TCP: Hash tables configured (established 524288 bind 65536) [ 0.437412] TCP reno registered [ 0.437431] UDP hash table entries: 2048 (order: 4, 65536 bytes) [ 0.437482] UDP-Lite hash table entries: 2048 (order: 4, 65536 bytes) [ 0.437678] NET: Registered protocol family 1 [ 0.437705] pci 0000:00:02.0: Boot video device [ 0.437892] PCI: CLS 64 bytes, default 64 [ 0.437916] Simple Boot Flag at 0x57 set to 0x1 [ 0.438294] audit: initializing netlink socket (disabled) [ 0.438309] type=2000 audit(1319243447.432:1): initialized [ 0.440763] Freeing initrd memory: 13416k freed [ 0.468362] HugeTLB registered 2 MB page size, pre-allocated 0 pages [ 0.488192] VFS: Disk quotas dquot_6.5.2 [ 0.488254] Dquot-cache hash table entries: 512 (order 0, 4096 bytes) [ 0.488888] fuse init (API version 7.16) [ 0.488985] msgmni has been set to 5890 [ 0.489381] Block layer SCSI generic (bsg) driver version 0.4 loaded (major 253) [ 0.489413] io scheduler noop registered [ 0.489415] io scheduler deadline registered [ 0.489460] io scheduler cfq registered (default) [ 0.489583] pcieport 0000:00:1c.0: setting latency timer to 64 [ 0.489633] pcieport 0000:00:1c.0: irq 40 for MSI/MSI-X [ 0.489699] pcieport 0000:00:1c.1: setting latency timer to 64 [ 0.489741] pcieport 0000:00:1c.1: irq 41 for MSI/MSI-X [ 0.489800] pcieport 0000:00:1c.2: setting latency timer to 64 [ 0.489841] pcieport 0000:00:1c.2: irq 42 for MSI/MSI-X [ 0.489904] pcieport 0000:00:1c.3: setting latency timer to 64 [ 0.489944] pcieport 0000:00:1c.3: irq 43 for MSI/MSI-X [ 0.490006] pcieport 0000:00:1c.4: setting latency timer to 64 [ 0.490047] pcieport 0000:00:1c.4: irq 44 for MSI/MSI-X [ 0.490126] pci_hotplug: PCI Hot Plug PCI Core version: 0.5 [ 0.490149] pciehp: PCI Express Hot Plug Controller Driver version: 0.4 [ 0.490196] intel_idle: MWAIT substates: 0x1110 [ 0.490198] intel_idle: does not run on family 6 model 15 [ 0.491240] ACPI: Deprecated procfs I/F for AC is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared [ 0.493473] ACPI: AC Adapter [ADP1] (on-line) [ 0.493590] input: Lid Switch as /devices/LNXSYSTM:00/device:00/PNP0C0D:00/input/input0 [ 0.496771] ACPI: Lid Switch [LID0] [ 0.496818] input: Sleep Button as /devices/LNXSYSTM:00/device:00/PNP0C0E:00/input/input1 [ 0.496823] ACPI: Sleep Button [SLPB] [ 0.496865] input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input2 [ 0.496869] ACPI: Power Button [PWRF] [ 0.496900] ACPI: acpi_idle registered with cpuidle [ 0.498719] Monitor-Mwait will be used to enter C-1 state [ 0.498753] Monitor-Mwait will be used to enter C-2 state [ 0.498761] Marking TSC unstable due to TSC halts in idle [ 0.517627] thermal LNXTHERM:00: registered as thermal_zone0 [ 0.517630] ACPI: Thermal Zone [TZS0] (67 C) [ 0.524796] thermal LNXTHERM:01: registered as thermal_zone1 [ 0.524799] ACPI: Thermal Zone [TZS1] (67 C) [ 0.524823] ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared [ 0.524852] ERST: Table is not found!

• Definition of the job titles involved in a software development process.

  - by Rafael Romão

  I have seen many job titles for people involved in a software development process, but never found a consensus about they mean. I know many of them are equivalent, and found some other questions about that here in SO, but I would like to know your definitions and comments about them. I want not only to know if there is really a consensus, but also to know if what I suppose to be a Software Architect, is really a Software Architect, and so on. The job titles I mean are: Developer; System Analyst; Programmer; Analyst Programmer; Software Engineer; Software Architect; Designer; Software Designer; Business Manager; Business Analyst; Program Manager; Project Manager; Development Manager; Tester; Support Analyst; Please, feel free to add more titles to this list in your answers. It would be very helpful.

• why do we need advanced knowledge of mathematics & physics for programming?

  - by Sumeet

  Guys, I have been very good in mathematics and physics in my schools and colleges. Right now I am a programmer. Even in the colleges I have to engrossed my self into computers and programming things all the time. As I used to like it very much. But I have always felt the lack of advanced mathematics and physics in all the work I have done (Programs). Programming never asked me any advanced mathematics and physics knowledge in what I was very good. It always ask u some optimized loops, and different programming technologies which has never been covered in advanced mathematics and physics. Even at the time of selection in big College , such a kind of advanced knowledge is required. Time by time I got out of touch of all that facts and concepts (advanced mathematics and physics). And now after, 5 years in job I found it hard to resolve Differentiations and integrations from Trigonometry. Which sometimes make me feel like I have wasted time in those concepts because they are never used. (At that time I knew that I am going to be a programmer) If one need to be a programmer why do all this advanced knowledge is required. One can go with elementry knowledge a bit more. You never got to think like scientists and R&D person in your Schols and colleges for being a programmer? Just think and let me know your thoughts. I must be wrong somewhere in what I think , but not able to figure that out..? Regards Sumeet

• Experience with Take home Programming Test for Interviews

  - by Alan

  Okay this is not "programming" related per-se, but it is a situation that I believe the SO audience would be more familiar with, than say an ask.yahoo.com audience, so please forgive me. I had a phone screen the other day with a company that I really want to work for. It went pretty well, based on cues from the HR person, such as "Next step we're going to send you a programming test," and "Well, before I get ahead of myself, do you want to continue the interviewing process." and "We'll send out the test later this afternoon. It doesn't sound like you'll have trouble with it, but I want to be honest we do have a high failure rate on it." The questions asked weren't technical, just going down my resume, and talking about the work I've done, and how it relates to the position. Nothing I couldn't talk through. This was last Thursday. It's now Tuesday, and haven't received the test yet. I sent a follow up email yesterday to the lady who interviewed me, but haven't gotten a response. Anyone had a similar experience? Am I reading too much into this? Or was I off the mark by thinking I had moved on to the next step in the interview process. Since this is a company I really want to work for, I'm driving myself insane enumerating all the various what-if scenarios.

• Should CV contain cases where certain party fools me and not pay salary? Is it "holiday" time or not?

  - by otto

  Suppose I am fooled to work in a start-up or a company that has been a very small over a long time, let say 10 years. I work them 3 months and I really enjoy the work -- I learn a lot of new skills such as Haskell, MapReduce, CouchDB and many other little things. Now the firm did not pay any salary: A) I may be unskilled, B) I did not meet some deadline (I don't know because I am not allowed to speak to the boss but I know that I am not getting any payment) or C) I was fooled. Some detail about C I heard that the firm have had similar cases from my friend, "The guy X was there and he said he does not trust the firm at all so he went to other firm". I don't know what the term "trust" mean here, anyway the firm consists of ignorant drop-outs that hires academic people, a bit irony. They hire people from student-organizations and let them work and promise ok -compensation but -- when you start working the co-employer starts all kind of instructions "Do not work so hard, do not work so long, do not work so much" -- it is like he is making sure you do not feel sad when he does not pay any salary (co-employer is an owner in the firm). Anyway, I learnt a ton in the company but it was very inefficient working. I worked only alone, not really working in a "company". Now should by resume contain references to the firm and the guy who did not pay me anything? Or should my resume read that I worked in XYZ -technologies -- but 1 year's NDA -- what can write here? Now I fear that if I put the firm to my resume: they will lie about my input to my next employer. I feel they are very dishonest. On the other hand, I want to make it sure that I have worked over the time. So: Should my CV contain the not-so-good or even awful employers that may be fooling people to work there? I am pretty sure everyone knows the firm and its habbits, circles are small but people are afraid to speak.

• hibernate empty collection in component

  - by Jurgen H

  I have a component mapped using Hibernate. If all fields in the component in the database are null, the component itself is set to null by hibernate. This is the expected behavior and also what I need. The problem I have, is that when I add a bag to that component, the bag is initialized to an empty list. This means the component has a non null value... resulting in the component being created. Any idea how to fix this? <class name="foo.bar.Entity" table="Entity"> <id name="id" column="id"> <generator class="native" /> </id> <property name="departure" column="departure_time" /> <property name="arrival" column="arrival_time" /> <component name="statistics"> <bag name="linkStatistics" lazy="false" cascade="all" > <key column="entity_id" not-null="true" /> <one-to-many class="foo.bar.LinkStatistics" /> </bag> <property name="loggedTime" column="logged_time" /> ... </component> A criteria with Restirctions.isNull("statistics") does return the expected values.

• Supporting users if they're not on your site

  - by Roger Hart

  Have a look at this Read Write Web article, specifically the paragraph in bold and the comments. Have a wry chuckle, or maybe weep for the future of humanity - your call. Then pause, and worry about information architecture. The short story: Read Write Web bumps up the Google rankings for "Facebook login" at the same time as Facebook makes UI changes, and a few hundred users get confused and leave comments on Read Write Web complaining about not being able to log in to their Facebook accounts.* Blindly clicking the first Google result is not a navigation behaviour I'd anticipated for folks visiting big names sites like Facebook. But then, I use Launchy and don't know where any of my files are, depend on Firefox auto-complete, view Facebook through my IM client, and don't need a map to find my backside with both hands. Not all our users behave in the same way, which means not all of our architecture is within our control, and people can get to your content in all sorts of ways. Even if the Read Write Web episode is a prank of some kind (there are, after all, plenty of folks who enjoy orchestrated trolling) it's still a useful reminder. Your users may take paths through and to your content you cannot control, and they are unlikely to deconstruct their assumptions along the way. I guess the meaningful question is: can you still support those users? If they get to you from Google instead of your front door, does what they find still make sense? Does your information architecture still work if your guests come in through the bathroom window? Ok, so here they broke into the house next door - you can't be expected to deal with that. But the rest is well worth thinking about. Other off-site interaction It's rarely going to be as funny as the comments at Read Write Web, but your users are going to do, say, and read things they think of as being about you and your products, in places you don't control. That's good. If you pay attention to it, you get data. Your users get a better experience. There are easy wins, too. Blogs, forums, social media &c. People may look for and find help with your product on blogs and forums, on Twitter, and what have you. They may learn about your brand in the same way. That's fine, it's an interaction you can be part of. It's time-consuming, certainly, but you have the option. You won't get a blogger to incorporate your site navigation just in case your users end up there, but you can be there when they do. Again, Anne Gentle, Gordon McLean and others have covered this in more depth than I could. Direct contact Sales people, customer care, support, they all talk to people. Are they sending links to your content? if so, which bits? Do they know about all of it? Do they have the content they need to support them - messaging that funnels sales, FAQ that are realistically frequent, detailed examples of things people want to do, that kind of thing. Are they sending links because users can't find the good stuff? Are they sending précis of your content, or re-writes, or brand new stuff? If so, does that mean your content isn't up to scratch, or that you've got content missing? Direct sales/care/support interactions are enormously valuable, and can help you know what content your users find useful. You can't have a table of contents or a "See also" in a phonecall, but your content strategy can support more interactions than browsing. *Passing observation about Facebook. For plenty if folks, it is  the internet. Its services are simple versions of what a lot of people use the internet for, and they're aggregated into one stop. Flickr, Vimeo, Wordpress, Twitter, LinkedIn, and all sorts of games, have Facebook doppelgangers that are not only friendlier to entry-level users, they're right there, behind only one layer of authentication. As such, it could own a lot of interaction convention. Heavy users may well not be tech-savvy, and be quite change averse. That doesn't make this episode not dumb, but I'm happy to go easy on 'em.

• Man pages not finding entry

  - by Mike

  So, I'm not sure what is going on with my system (ubuntu 12.04), but my man pages do not seem to be working. I try man gcc and get the following response No manual entry for gcc See 'man 7 undocumented' for help when manual pages are not available.

• Advanced Continuous Delivery to Azure from TFS, Part 1: Good Enough Is Not Great

  - by jasont

  The folks over on the TFS / Visual Studio team have been working hard at releasing a steady stream of new features for their new hosted Team Foundation Service in the cloud. One of the most significant features released was simple continuous delivery of your solution into your Azure deployments. The original announcement from Brian Harry can be found here. Team Foundation Service is a great platform for .Net developers who are used to working with TFS on-premises. I’ve been using it since it became available at the //BUILD conference in 2011, and when I recently came to work at Stackify, it was one of the first changes I made. Managing work items is much easier than the tool we were using previously, although there are some limitations (more on that in another blog post). However, when continuous deployment was made available, it blew my mind. It was the killer feature I didn’t know I needed. Not to say that I wasn’t previously an advocate for continuous delivery; just that it was always a pain to set up and configure. Having it hosted - and a one-click setup – well, that’s just the best thing since sliced bread. It made perfect sense: my source code is in the cloud, and my deployment is in the cloud. Great! I can queue up a build from my iPad or phone and just let it go! I quickly tore through the quick setup and saw it all work… sort of. This will be the first in a three part series on how to take the building block of Team Foundation Service continuous delivery and build a CD model that will actually work for any team deploying something more advanced than a “Hello World” example. Part 1: Good Enough Is Not Great Part 2: A Model That Works: Branching and Multiple Deployment Environments Part 3: Other Considerations: SQL, Custom Tasks, Etc Good Enough Is Not Great There. I’ve said it. I certainly hope no one on the TFS team is offended, but it’s the truth. Let’s take a look under the hood and understand how it works, and then why it’s not enough to handle real world CD as-is. How it works. (note that I’ve skipped a couple of steps; I already have my accounts set up and something deployed to Azure) The first step is to establish some oAuth magic between your Azure management portal and your TFS Instance. You do this via the management portal. Once it’s done, you have a new build process template in your TFS instance. (Image lifted from the documentation) From here, you’ll get the usual prompts for security, allowing access, etc. But you’ll also get to pick which Solution in your source control to build. Here’s what the bulk of the build definition looks like. All I’ve had to do is add in the solution to build (notice that mine is from a specific branch – Release – more on that later) and I’ve changed the configuration. I trigger the build, and voila! I have an Azure deployment a few minutes later. The beauty of this is that it’s all in the cloud and I’m not waiting for my machine to compile and upload the package. (I also had to enable the build definition first – by default it is created in disabled state, probably a good thing since it will trigger on every.single.checkin by default.) I get to see a history of deployments from the Azure portal, and can link into TFS to see the associated changesets and work items. You’ll notice also that this build definition also automatically put my code in the Staging slot of my Azure deployment – more on this soon. For now, I can VIP swap and be in production. (P.S. I hate VIP swap and “production” and “staging” in Azure. More on that later too.) That’s it. That’s the default out-of-box experience. Easy, right? But it’s full of room for improvement, so let’s get into that….   The Problems Nothing is perfect (except my code – it’s always perfect), and neither is Continuous Deployment without a bit of work to help it fit your dev team’s process. So what are the issues? Issue 1: Staging vs QA vs Prod vs whatever other environments your team may have. This, for me, is the big hairy one. Remember how this automatically deployed to staging rather than prod for us? There are a couple of issues with this model: If I want to deliver to prod, it requires intervention on my part after deployment (via a VIP swap). If I truly want to promote between environments (i.e. Nightly Build –> Stable QA –> Production) I likely have configuration changes between each environment such as database connection strings and this process (and the VIP swap) doesn’t account for this. Yet. Issue 2: Branching and delivering on every check-in. As I mentioned above, I have set this up to target a specific branch – Release – of my code. For the purposes of this example, I have adopted the “basic” branching strategy as defined by the ALM Rangers. This basically establishes a “Main” trunk where you branch off Dev and Release branches. Granted, the Release branch is usually the only thing you will deploy to production, but you certainly don’t want to roll to production automatically when you merge to the Release branch and check-in (unless you like the thrill of it, and in that case, I like your style, cowboy….). Rather, you have nightly build and QA environments, or if you’ve adopted the feature-branch model you have environments for those. Those are the environments you want to continuously deploy to. But that takes us back to Issue 1: we currently have a 1:1 solution to Azure deployment target. Issue 3: SQL and other custom tasks. Let’s be honest and address the elephant in the room: I need to get some sleep because I see an elephant in the room. But seriously, I can’t think of an application I have touched in the last 10 years that doesn’t need to consider SQL changes when deploying code and upgrading an environment. Microsoft seems perfectly content to ignore this elephant for now: yes, they’ve added Data Tier Applications. But let’s be honest with ourselves again: no one really uses it, and it’s not suitable for anything more complex than a Hello World sample project database. Why? Because it doesn’t fit well into a great source control story. Developers make stored procedure and table changes all day long while coding complex applications, and if someone forgets to go update the DACPAC before the automated deployment, you have a broken build until it’s completed. Developers – not just DBAs – also like to work with SQL in SQL tools, not in Visual Studio. I’m really picking on SQL because that’s generally the biggest concern that I hear. But we need to account for any custom tasks as well in the build process.   The Solutions… ? We’ve taken a look at how this all works, and addressed the shortcomings. In my next post (which I promise will be very, very soon), I will detail how I’ve overcome these shortcomings and used this foundation to create a mature, flexible model for deploying my app – any version, any time, to any environment.

• Meta description not displaying in custom site search results page

  - by Stephen Connolly

  We have Google Custom Site Search implemented on our company website. When I'm looking at the results page, I noticed that the Meta Description is not being displayed. It just seems to be reading the links titles from our drop down menu and using this as a description. When I search for the same page via google.com, the meta description is pulled in correctly. Any thoughts why this might be happening. I can't see anything in the Custom Site Search settings.

• Why not AJAX'ify entire websites?

  - by Anonymous -

  Is there any solid reasoning as to why sites shouldn't be developed with ajax functionality that loads major parts of each part (assuming there are elements like the header, navigation etc that remain the same)? Surely it would be less resource-intensive since the server wouldn't have to serve content that appears on every page, benefiting both the host and end-user. Answer the question taking into consideration: The sites javascript behaviour degrades gracefully in every instance For my question I'm talking about new sites where this behaviour could be implemented rather from the off, so it doesn't technically cost any money - we're not returning to a finished product to implement it.

• To implement registration page with Vaadin or not?

  - by JVerstry

  This is a tactical implementation question about usage of Vaadin or in some part of my application. Vaadin is a great framework to login users and implement sophisticated web applications with many pages. However, I think it is not very well suited to desgin pages to register new users for my application. Am I right? Am I am wrong? It seems to me that a simple HTML/CSS/Javascript login + email registration + confirmation email with confirmation link cannot be implemented easily with Vaadin. It seems like Vaadin would be overkill. Do you agree? Or am I missing something? I am looking for feedback from experienced Vaadin users.

• Not getting desired results with SSAO implementation

  - by user1294203

  After having implemented deferred rendering, I tried my luck with a SSAO implementation using this Tutorial. Unfortunately, I'm not getting anything that looks like SSAO, you can see my result below. You can see there is some weird pattern forming and there is no occlusion shading where there needs to be (i.e. in between the objects and on the ground). The shaders I implemented follow: #VS #version 330 core uniform mat4 invProjMatrix; layout(location = 0) in vec3 in_Position; layout(location = 2) in vec2 in_TexCoord; noperspective out vec2 pass_TexCoord; smooth out vec3 viewRay; void main(void){ pass_TexCoord = in_TexCoord; viewRay = (invProjMatrix * vec4(in_Position, 1.0)).xyz; gl_Position = vec4(in_Position, 1.0); } #FS #version 330 core uniform sampler2D DepthMap; uniform sampler2D NormalMap; uniform sampler2D noise; uniform vec2 projAB; uniform ivec3 noiseScale_kernelSize; uniform vec3 kernel[16]; uniform float RADIUS; uniform mat4 projectionMatrix; noperspective in vec2 pass_TexCoord; smooth in vec3 viewRay; layout(location = 0) out float out_AO; vec3 CalcPosition(void){ float depth = texture(DepthMap, pass_TexCoord).r; float linearDepth = projAB.y / (depth - projAB.x); vec3 ray = normalize(viewRay); ray = ray / ray.z; return linearDepth * ray; } mat3 CalcRMatrix(vec3 normal, vec2 texcoord){ ivec2 noiseScale = noiseScale_kernelSize.xy; vec3 rvec = texture(noise, texcoord * noiseScale).xyz; vec3 tangent = normalize(rvec - normal * dot(rvec, normal)); vec3 bitangent = cross(normal, tangent); return mat3(tangent, bitangent, normal); } void main(void){ vec2 TexCoord = pass_TexCoord; vec3 Position = CalcPosition(); vec3 Normal = normalize(texture(NormalMap, TexCoord).xyz); mat3 RotationMatrix = CalcRMatrix(Normal, TexCoord); int kernelSize = noiseScale_kernelSize.z; float occlusion = 0.0; for(int i = 0; i < kernelSize; i++){ // Get sample position vec3 sample = RotationMatrix * kernel[i]; sample = sample * RADIUS + Position; // Project and bias sample position to get its texture coordinates vec4 offset = projectionMatrix * vec4(sample, 1.0); offset.xy /= offset.w; offset.xy = offset.xy * 0.5 + 0.5; // Get sample depth float sample_depth = texture(DepthMap, offset.xy).r; float linearDepth = projAB.y / (sample_depth - projAB.x); if(abs(Position.z - linearDepth ) < RADIUS){ occlusion += (linearDepth <= sample.z) ? 1.0 : 0.0; } } out_AO = 1.0 - (occlusion / kernelSize); } I draw a full screen quad and pass Depth and Normal textures. Normals are in RGBA16F with the alpha channel reserved for the AO factor in the blur pass. I store depth in a non linear Depth buffer (32F) and recover the linear depth using: float linearDepth = projAB.y / (depth - projAB.x); where projAB.y is calculated as: and projAB.x as: These are derived from the glm::perspective(gluperspective) matrix. z_n and z_f are the near and far clip distance. As described in the link I posted on the top, the method creates samples in a hemisphere with higher distribution close to the center. It then uses random vectors from a texture to rotate the hemisphere randomly around the Z direction and finally orients it along the normal at the given pixel. Since the result is noisy, a blur pass follows the SSAO pass. Anyway, my position reconstruction doesn't seem to be wrong since I also tried doing the same but with the position passed from a texture instead of being reconstructed. I also tried playing with the Radius, noise texture size and number of samples and with different kinds of texture formats, with no luck. For some reason when changing the Radius, nothing changes. Does anyone have any suggestions? What could be going wrong?

• First mouse click not detected

  - by user286169

  Since a few days my mouse reacts different on a click. The first click is not working properly, it seems as it is interpreted as a hoover, the second click is interpreted as the first 'real' click. I tried switching left and right buttons, but behaviour stays the same. Tried restarting unity, implemented ctrl_alt_bksp, but didn't help either. I am running 14.04 Ubuntu, and have all packages up-to-date using apt-get update/upgrade. Is there anybody with a clue? Thanks in advance! Patrick

• How come verification does not include actual testing?

  - by user970696

  Having read a lot about this topic, I still did not get it. Verification should prove that you are building the product right, while validation you build the right product. But only static techniques are mentioned as being verification methods (code reviews, requirements checks...). But how can you say if its implemented correctly if you do not test it? It is said that verification checks e.g. code for its correctnes. Verification - ensure that the product meet specified requirements. Again, if the function is specified to work somehow, only by testing I can say that it does. Could anyone explain this to me please? EDIT: As Wiki says: Verification:Preparing of the test cases (based on the analysis of the requireemnts) Validation: Running of the test cases

• Different Not Automatically Implies Better

  - by Alois Kraus

  Originally posted on: http://geekswithblogs.net/akraus1/archive/2013/11/05/154556.aspxRecently I was digging deeper why some WCF hosted workflow application did consume quite a lot of memory although it did basically only load a xaml workflow. The first tool of choice is Process Explorer or even better Process Hacker (has more options and the best feature copy&paste does work). The three most important numbers of a process with regards to memory are Working Set, Private Working Set and Private Bytes. Working set is the currently consumed physical memory (parts can be shared between processes e.g. loaded dlls which are read only) Private Working Set is the physical memory needed by this process which is not shareable Private Bytes is the number of non shareable which is only visible in the current process (e.g. all new, malloc, VirtualAlloc calls do create private bytes) When you have a bigger workflow it can consume under 64 bit easily 500MB for a 1-2 MB xaml file. This does not look very scalable. Under 64 bit the issue is excessive private bytes consumption and not the managed heap. The picture is quite different for 32 bit which looks a bit strange but it seems that the hosted VB compiler is a lot less memory hungry under 32 bit. I did try to repro the issue with a medium sized xaml file (400KB) which does contain 1000 variables and 1000 if which can be represented by C# code like this: string Var1; string Var2; ... string Var1000; if (!String.IsNullOrEmpty(Var1) ) { Console.WriteLine(“Var1”); } if (!String.IsNullOrEmpty(Var2) ) { Console.WriteLine(“Var2”); } ....   Since WF is based on VB.NET expressions you are bound to the hosted VB.NET compiler which does result in (x64) 140 MB of private bytes which is ca. 140 KB for each if clause which is quite a lot if you think about the actually present functionality. But there is hope. .NET 4.5 does allow now C# expressions for WF which is a major step forward for all C# lovers. I did create some simple patcher to “cross compile” my xaml to C# expressions. Lets look at the result: C# Expressions VB Expressions x86 x86 On my home machine I have only 32 bit which gives you quite exactly half of the memory consumption under 64 bit. C# expressions are 10 times more memory hungry than VB.NET expressions! I wanted to do more with less memory but instead it did consume a magnitude more memory. That is surprising to say the least. The workflow does initialize in about the same time under x64 and x86 where the VB code does it in 2s whereas the C# version needs 18s. Also nearly ten times slower. That is a too high price to pay for any bigger sized xaml workflow to convert from VB.NET to C# expressions. If I do reduce the number of expressions to 500 then it does need 400MB which is about half of the memory. It seems that the cost per if does rise linear with the number of total expressions in a xaml workflow.  Expression Language Cost per IF Startup Time C# 1000 Ifs x64 1,5 MB 18s C# 500 Ifs x64 750 KB 9s VB 1000 Ifs x64 140 KB 2s VB 500 Ifs x64 70 KB 1s Now we can directly compare two MS implementations. It is clear that the VB.NET compiler uses the same underlying structure but it has much higher offset compared to the highly inefficient C# expression compiler. I have filed a connect bug here with a harsher wording about recent advances in memory consumption. The funniest thing is that one MS employee did give an Azure AppFabric demo around early 2011 which was so slow that he needed to investigate with xperf. He was after startup time and the call stacks with regards to VB.NET expression compilation were remarkably similar. In fact I only found this post by googling for parts of my call stacks. … “C# expressions will be coming soon to WF, and that will have different performance characteristics than VB” … What did he know Jan 2011 what I did no know until today? ;-). He knew that C# expression will come but that they will not be automatically have better footprint. It is about time to fix that. In its current state C# expressions are not usable for bigger workflows. That also explains the headline for today. You can cheat startup time by prestarting workflows so that the demo looks nice and snappy but it does hurt scalability a lot since you do need much more memory than necessary. I did find the stacks by enabling virtual allocation tracking within XPerf which is still the best tool out there. But first you need to look at your process to check where the memory is hiding: For the C# Expression compiler you do not need xperf. You can directly dump the managed heap and check with a profiler of your choice. But if the allocations are happening on the Private Data ( VirtualAlloc ) you can find it with xperf. There is a nice video on channel 9 explaining VirtualAlloc tracking it in greater detail. If your data allocations are on the Heap it does mean that the C/C++ runtime did create a heap for you where all malloc, new calls do allocate from it. You can enable heap tracing with xperf and full call stack support as well which is doable via xperf like it is shown also on channel 9. Or you can use WPRUI directly: To make “Heap Usage” it work you need to set for your executable the tracing flags (before you start it). For example devenv.exe HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\devenv.exe DWORD TracingFlags 1 Do not forget to disable it after you did complete profiling the process or it will impact the startup time quite a lot. You can with xperf attach directly to a running process and collect heap allocation information from a gone wild process. Very handy if you need to find out what a process was doing which has arrived in a funny state. “VirtualAlloc usage” does work without explicitly enabling stuff for a specific process and is always on machine wide. I had issues on my Windows 7 machines with the call stack collection and the latest Windows 8.1 Performance Toolkit. I was told that WPA from Windows 8.0 should work fine but I do not want to downgrade.

• Proxied calls not working as expected

  - by AndyH

  I have been modifying an application to have a cleaner client/server split to allow for load splitting and resource sharing etc. Everything is written to an interface so it was easy to add a remoting layer to the interface using a proxy. Everything worked fine. The next phase was to add a caching layer to the interface and again this worked fine and speed was improved but not as much as I would have expected. On inspection it became very clear what was going on. I feel sure that this behavior has been seen many times before and there is probably a design pattern to solve the problem but it eludes me and I'm not even sure how to describe it. It is easiest explained with an example. Let's imagine the interface is interface IMyCode { List<IThing> getLots( List<String> ); IThing getOne( String id ); } The getLots() method calls getOne() and fills up the list before returning. The interface is implemented at the client which is proxied to a remoting client which then calls the remoting server which in turn calls the implementation at the server. At the client and the server layers there is also a cache. So we have :- Client interface | Client cache | Remote client | Remote server | Server cache | Server interface If we call getOne("A") at the client interface, the call is passed to the client cache which faults. This then calls the remote client which passes the call to the remote server. This then calls the server cache which also faults and so the call is eventually passed to the server interface which actually gets the IThing. In turn the server cache is filled and finally the client cache also. If getOne("A") is again called at the client interface the client cache has the data and it gets returned immediately. If a second client called getOne("B") it would fill the server cache with "B" as well as it's own client cache. Then, when the first client calls getOne("B") the client cache faults but the server cache has the data. This is all as one would expect and works well. Now lets call getLots( [ "C", "D" ] ). This works as you would expect by calling getOne() twice but there is a subtlety here. The call to getLots() cannot directly make use of the cache. Therefore the sequence is to call the client interface which in turn calls the remote client, then the remote server and eventually the server interface. This then calls getOne() to fill the list before returning. The problem is that the getOne() calls are being satisfied at the server when ideally they should be satisfied at the client. If you imagine that the client/server link is really slow then it becomes clear why the client call is more efficient than the server call once the client cache has the data. This example is contrived to illustrate the point. The more general problem is that you cannot just keep adding proxied layers to an interface and expect it to work as you would imagine. As soon as the call goes 'through' the proxy any subsequent calls are on the proxied side rather than 'self' side. Have I failed to learn or not learned something correctly? All this is implemented in Java and I haven't used EJBs. It seems that the example may be confusing. The problem is nothing to do with cache efficiencies. It is more to do with an illusion created by the use of proxies or AOP techniques in general. When you have an object whose class implements an interface there is an assumption that a call on that object might make further calls on that same object. For example, public String getInternalString() { return InetAddress.getLocalHost().toString(); } public String getString() { return getInternalString(); } If you get an object and call getString() the result depends where the code is running. If you add a remoting proxy to the class then the result could be different for calls to getString() and getInternalString() on the same object. This is because the initial call gets 'deproxied' before the actual method is called. I find this not only confusing but I wonder how I can control this behavior especially as the use of the proxy may be by a third party. The concept is fine but the practice is certainly not what I expected. Have I missed the point somewhere?

From that entity game player select the tower and drag to the actual position where he want to plot the tower. I set the entity in HUD also, so user scroll and zoom the region, the tower become visible all the time. Basically I have created the different entity to show and hide towers only so I can manage it easily. My problem is when I have not perform the scroll and zoom the tower touch and the dragging easily done but when I zoom and scroll the scene at that time the tower touch event does not call so the player can not able to drag and drop it to actual position. So anybody please help me to come out of it.

• RapidXML - does not compile ?

  - by milan

  Hi, I am novice to rapidXML but first impresion was not positive, I made simple Visual Studio 6 C++ Hello World Application and added RapidXML hpp files to project and in main.cpp I put: #include "stdafx.h" #include < iostream > #include < string > #include "rapidxml.hpp" using namespace std; using namespace rapidxml; int main ( ) { char x[] = "<Something>Text</Something>\0" ; //<<<< funktioniert, aber mit '*' nicht xml_document<> doc ; doc.parse<0>(x) ; cout << "Name of my first node is: " << doc.first_node()->name() << endl ; xml_node<>* node = doc.first_node("Something") ; cout << "Node 'Something' has value: " << node->value() << endl ; } And it does not compile, any help ? Is RapidXML possible to run with Visual Studio 6 ? Error I am getting are: --------------------Configuration: aaa - Win32 Debug-------------------- Compiling... rapidxml.cpp c:\Parser\rapidxml.cpp(310) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(320) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(320) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(385) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(639) : see reference to class template instantiation 'rapidxml::memory_pool<Ch>' being compiled c:\Parser\rapidxml.cpp(417) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(639) : see reference to class template instantiation 'rapidxml::memory_pool<Ch>' being compiled c:\Parser\rapidxml.cpp(417) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(639) : see reference to class template instantiation 'rapidxml::memory_pool<Ch>' being compiled c:\Parser\rapidxml.cpp(448) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(639) : see reference to class template instantiation 'rapidxml::memory_pool<Ch>' being compiled c:\Parser\rapidxml.cpp(448) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(639) : see reference to class template instantiation 'rapidxml::memory_pool<Ch>' being compiled c:\Parser\rapidxml.cpp(476) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(639) : see reference to class template instantiation 'rapidxml::memory_pool<Ch>' being compiled c:\Parser\rapidxml.cpp(579) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(639) : see reference to class template instantiation 'rapidxml::memory_pool<Ch>' being compiled c:\Parser\rapidxml.cpp(599) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(639) : see reference to class template instantiation 'rapidxml::memory_pool<Ch>' being compiled c:\Parser\rapidxml.cpp(681) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(790) : see reference to class template instantiation 'rapidxml::xml_base<Ch>' being compiled c:\Parser\rapidxml.cpp(700) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(790) : see reference to class template instantiation 'rapidxml::xml_base<Ch>' being compiled c:\Parser\rapidxml.cpp(721) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(790) : see reference to class template instantiation 'rapidxml::xml_base<Ch>' being compiled c:\Parser\rapidxml.cpp(751) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(790) : see reference to class template instantiation 'rapidxml::xml_base<Ch>' being compiled c:\Parser\rapidxml.cpp(786) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(790) : see reference to class template instantiation 'rapidxml::xml_base<Ch>' being compiled c:\Parser\rapidxml.cpp(787) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(790) : see reference to class template instantiation 'rapidxml::xml_base<Ch>' being compiled c:\Parser\rapidxml.cpp(836) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(876) : see reference to class template instantiation 'rapidxml::xml_attribute<Ch>' being compiled c:\Parser\rapidxml.cpp(856) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(876) : see reference to class template instantiation 'rapidxml::xml_attribute<Ch>' being compiled c:\Parser\rapidxml.cpp(936) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(1345) : see reference to class template instantiation 'rapidxml::xml_node<Ch>' being compiled c:\Parser\rapidxml.cpp(958) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(1345) : see reference to class template instantiation 'rapidxml::xml_node<Ch>' being compiled c:\Parser\rapidxml.cpp(981) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(1345) : see reference to class template instantiation 'rapidxml::xml_node<Ch>' being compiled c:\Parser\rapidxml.cpp(1004) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(1345) : see reference to class template instantiation 'rapidxml::xml_node<Ch>' being compiled c:\Parser\rapidxml.cpp(1025) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(1345) : see reference to class template instantiation 'rapidxml::xml_node<Ch>' being compiled c:\Parser\rapidxml.cpp(1045) : error C2039: 'size_t' : is not a member of 'std' c:\Parser\rapidxml.cpp(1345) : see reference to class template instantiation 'rapidxml::xml_node<Ch>' being compiled Error executing cl.exe. rapidxml.obj - 25 error(s), 0 warning(s)

• 12.04 Unity 3D Not working where as Unity 2D works fine

  - by Stephen Martin

  I updated from 11.10 to 12.04 using the distribution upgrade, after that I couldn't log into using the Unity 3D desktop after logging in I would either never get unity's launcher or I would get the launcher and once I tried to do anything the windows lost their decoration and nothing would respond. If I use Unity 2D it works fine and in fact I'm using it to type this. I managed to get some info out of dmesg that looks like it's the route of whats happening. dmesg: [ 109.160165] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

Unity 3D worked fine in 11.10
