  • How does one validate html that's generated from JS running in the browser?

    - by Henry Rose
    The page in question has very skeletal html sent over the wire to facilitate the building of a complicated UI in javascript. I'm now encountering a strange browser compatibility issue that feels very much like I've got a markup problem somewhere on the page. I've validated the page as it comes across the wire using the W3C tool and ensured there are no issues in that html. I've also tried validating the output of running on the browser console: document.getElementsByTagName('html')[0].outerHTML I find that the output of the above introduces lots of new issues, such as removing the trailing '/' in self closing tags. This added noise is distracting, but it also makes me uneasy about validating this method. How do you validate markup that's rendered client side?

  • Why my linux signal handler run only once

    - by Henry Fané
    #include <iostream> #include <signal.h> #include <fenv.h> #include <string.h> void signal_handler(int sig, siginfo_t *siginfo, void* context) { std::cout << " signal_handler " << fetestexcept(FE_ALL_EXCEPT) << std::endl; throw "exception"; } void divide() { float a = 1000., b = 0., c, f = 1e-300; c = a / b; std::cout << c << " and f = " << f << std::endl; } void init_sig_hanlder() { feenableexcept(FE_ALL_EXCEPT); struct sigaction sa, initial_sa; sa.sa_sigaction = &signal_handler ; sigemptyset( &sa.sa_mask ) ; sa.sa_flags = SA_SIGINFO; // man sigaction(3) // allows for void(*)(int,siginfo_t*,void*) handler sigaction(SIGFPE, &sa, &initial_sa); } int main(int argc, char** argv) { init_sig_hanlder(); while(true) { try { sleep(1); divide(); } catch(const char * a) { std::cout << "Exception in catch: " << a << std::endl; } catch(...) { std::cout << "Exception in ..." << std::endl; } } return 0; } Produce the following results on Linux/g++4.2: signal_handler 0 Exception in catch: exception inf and f = 0 inf and f = 0 inf and f = 0 inf and f = 0 So, signal handler is executed the first time but the next fp exception does not trigger the handler again. Where am I wrong ?

  • How to use PHP Time function to set a time variable of '09:30', add a specific amount of seconds and

    - by Henry
    Hi guys, hopefully you can help me here. I have some code (please see below) which takes the current time, then adds specific seconds to the time and re-displays the time 1 minute in the future. Instead of the time being the current time, I want it to be a time which I set - say 9:30. Then I want to be able to add, for example 65 seconds and it shows me 9:31. Please can you show me how to change it from current time, to a specific time I can set myself. Thank you. <?php $my_time = date('h:i:s',time()); $seconds2add = 65; $new_time= strtotime($my_time); $new_time+=$seconds2add; echo date('h:i:s',$new_time); ?>

  • NoSQL vs Relational Coding Styles

    - by Chris Henry
    When building objects that make use of data stored in a RDBMS, it's normally pretty clear what you're getting back, as dictated by the tables and columns being queried. However, when dealing with NoSQL, document-based systems, it's less clear what is being retrieved. What are common methods of keeping track of structure in which data is stored?

  • Are you ready for the needed changes to your Supply Chain for 2013?

    - by Stephen Slade
    With the initiation of the Dodd-Frank Act, companies need to determine if their products contain 'conflict materials' from certain global markets as the Rep of Congo. The materials include metals such as gold, tin, tungsten and tantalum. Compaines with global sourcing face new disclosure requirements in Feb'13 related to business being done in Iran. Public companies are required to disclose to U.S. security regulators if they or their affiliates are engaged in business in Iran either directly or indirectly.  Is your supply chain compliant?  Do you have sourcing reports to validate?  Where are the materials in your chips & circuit boards coming from? In the next few weeks, responsible companies will be scrutinizing their supply chains, subs, JVs, and affiliates to search for exposure.

  • I'm working on my resume for a job fair this week; any tips? [closed]

    - by buu700
    This will change as I update the document, but here is my resume. The job fair I'm going to is really huge (very good chance that it will determine where I intern this summer), so I would definitely appreciate any possible assistance in polishing this up. Any advice possible will be appreciated, ranging from spacing or absurdly minor formatting issues, to rearranging bullet points, to browser incompatibilities, to major changes in anything I've organised or written. At the moment, my only specific question is whether easter eggs are acceptable (specifically, if representatives who understand the reference will generally frown upon my inclusion of "Hacked The Gibson", given the context). Also, if anyone wants to evaluate it (e.g. font size, final arrangement, etc.), here is a PDF snapshot of the document at the time this question was submitted (the final version will have a different file name and appropriate metadata, for the record). Thanks!

  • In Java, howd do I iterate through lines in a textfile from back to front

    - by rogue780
    Basically I need to take a text file such as : Fred Bernie Henry and be able to read them from the file in the order of Henry Bernie Fred The actual file I'm reading from is 30MB and it would be a less than perfect solution to read the whole file, split it into an array, reverse the array and then go from there. It takes way too long. My specific goal is to find the first occurrence of a string (in this case it's "InitGame") and then return the position beginning of the beginning of that line. I did something like this in python before. My method was to seek to the end of the file - 1024, then read lines until I get to the end, then seek another 1024 from my previous starting point and, by using tell(), I would stop when I got to the previous starting point. So I would read those blocks backwards from the end of the file until I found the text I was looking for. So far, I'm having a heck of a time doing this in Java. Any help would be greatly appreciated and if you live near Baltimore it may even end up with you getting some fresh baked cookies. Thanks!

  • Quote of the Day: A Credo

    - by BuckWoody
    To live content with small means, to seek elegance rather than luxury, and refinement rather than fashion, to be worthy, not respectable, and wealthy, not rich, to study hard, think quietly, talk gently, act frankly, to listen to stars and birds, to babes and sages, with open heart, to bear all cheerfully, do all bravely, await occasions, hurry never, in a word to let the spiritual, unbidden and unconscious, grow up through the common, this is to be my symphony.

  • PRISM : la France aurait-elle dû accueillir Edward Snowden ? Une demande soutenue par les Verts, le Parti de Gauche et le Front National

    PRISM : la France aurait-elle dû accueillir Edward Snowden ? Une demande soutenue par les Verts, le Parti de Gauche et le Front NationalLe moins que l'on puisse dire, c'est que la classe politique française a assez peu apprécié les révélations du Spiegel sur l'espionnage par les États-Unis de ses alliés européens. Et encore moins les tentatives du secrétaire d'État américain John Kerry et du Président Barack Obama de relativiser à outrance les faits pour désamorcer l'affaire.Si certains jouent la carte du recul (comme Fleur Pellerin pour qui « ce n'est pas vraiment la première fois que ça arrive dans l'Histoire » ou Henry Guaino qui...

  • Agile Executives

    - by Robert May
    Over the years, I have experienced many different styles of software development. In the early days, most of the development was Waterfall development. In the last few years, I’ve become an advocate of Scrum. As I talked about last month, many people have misconceptions about what Scrum really is. The reason why we do Scrum at Veracity is because of the difference it makes in the life of the team doing Scrum. Software is for people, and happy motivated people will build better software. However, not all executives understand Scrum and how to get the information from development teams that use Scrum. I think that these executives need a support system for managing Agile teams. Historical Software Management When Henry Ford pioneered the assembly line, I doubt he realized the impact he’d have on Management through the ages. Historically, management was about managing the process of building things. The people were just cogs in that process. Like all cogs, they were replaceable. Unfortunately, most of the software industry followed this same style of management. Many of today’s senior managers learned how to manage companies before software was a significant influence on how the company did business. Software development is a very creative process, but too many managers have treated it like an assembly line. Idea’s go in, working software comes out, and we just have to figure out how to make sure that the ideas going in are perfect, then the software will be perfect. Lean Manufacturing In the manufacturing industry, Lean manufacturing has revolutionized Henry Ford’s assembly line. Derived from the Toyota process, Lean places emphasis on always providing value for the customer. Anything the customer wouldn’t be willing to pay for is wasteful. Agile is based on similar principles. We’re building software for people, and anything that isn’t useful to them doesn’t add value. Waterfall development would have teams build reams and reams of documentation about how the software should work. Agile development dispenses with this work because excessive documentation doesn’t add value. Instead, teams focus on building documentation only when it truly adds value to the customer. Many other Agile principals are similar. Playing Catch-up Just like in the manufacturing industry, many managers in the software industry have yet to understand the value of the principles of Lean and Agile. They think they can wrap the uncertainties of software development up in a nice little package and then just execute, usually followed by failure. They spend a great deal of time and money trying to exactly predict the future. That expenditure of time and money doesn’t add value to the customer. Managers that understand that Agile know that there is a better way. They will instead focus on the priorities of the near term in detail, and leave the future to take care of itself. They have very detailed two week plans with less detailed quarterly plans. These plans are guided by a general corporate strategy that doesn’t focus on the exact implementation details. These managers also think in smaller features rather than large functionality. This adds a great deal of value to customers, since the features that matter most are the ones that the team focuses on in the near term and then are able to deliver to the customers that are paying for them. Agile managers also realize that stale software is very costly. They know that keeping the technology in their software current is much less expensive and risky than large rewrites that occur infrequently and schedule time in each release for refactoring of the existing software. Agile Executives Even though Agile is a better way, I’ve still seen failures using the Agile process. While some of these failures can be attributed to the team, most of them are caused by managers, not the team. Managers fail to understand what Agile is, how it works, and how to get the information that they need to make good business decisions. I think this is a shame. I’m very pleased that Veracity understands this problem and is trying to do something about it. Veracity is a key sponsor of Agile Executives. In fact, Galen is this year’s acting president for Agile Executives. The purpose of Agile Executives is to help managers better manage Agile teams and see better success. Agile Executives is trying to build a community of executives that range from managers interested in Agile to managers that have successfully adopted Agile. Together, these managers can form a community of support and ideas that will help make Agile teams more successful. Helping Your Team You can help too! Talk with your manager and get them involved in Agile Executives. Help Veracity build the community. If your manager understands Agile better, he’ll understand how to help his teams, which will result in software that adds more value for customers. If you have any questions about how you can be involved, please let me know. Technorati Tags: Agile,Agile Executives

  • Procedural Planets, Heightmaps and Textures

    - by henryprescott
    I am currently working on an OpenGL procedural planet generator. I hope to use it for a space RPG, that will not allow players to go down to the surface of a planet so I have ignored anything ROAM related. At the momement I am drawing a cube with VBOs and mapping onto a sphere. I am familiar with most fractal heightmap generating techniques and have already implemented my own version of midpoint displacement(not that useful in this case I know). My question is, what is the best way to procedurally generate the heightmap. I have looked at libnoise which allows me to make tilable heightmaps/textures, but as far as I can see I would need to generate a net like this. Leaving the tiling obvious. Could anyone advise me on the best route to take? Any input would be much appreciated. Thanks, Henry.

  • boot loading problem after wubi installation of Ubuntu 12.04 on Win7

    - by user63085
    I was new in Ubuntu OS and I was just trying to use wubi windows installer to get a Ubuntu first for hands-on. I followed exactly the same as the instructions and after reboot win7, there is no Ubuntu selection in windows boot manager, with only Windows 7 showing there evilly -.- What I've found out was that the grub folder inside Ubuntu folder ( in my C:\ drive) was empty, either inside the ubuntu\disks\grub or ubuntu\install\grub. I thought this might be the reason why I could not load ubuntu during startup. Cause I've also looked into the EasyBCD settings, and ubuntu entry with Bootloader Path: \ubuntu\winboot\wubildr.mbr was lying there peacefully, looking perfectly fine. However it was not in boot loader actually. Is there a way to restore the grub folder with grub2, or is there any way to fix this problem so that I can find the "Ubuntu" selection at windows startup? Very appreciate your help :) Henry

  • I have a 18MB MySQL table backup. How can I restore such a large SQL file?

    - by Henryz
    I use a Wordpress plugin called 'Shopp'. It stores product images in the database rather than the filesystem as standard, I didn't think anything of this until now. I have to move server, and so I made a backup, but restoring the backup is proving a horrible task. I need to restore one table called wp_shopp_assets which is 18MB. Any advice is hugely appreciated. Thanks, Henry.

  • What is the S.M.A.R.T. page?

    - by Mads Skjern
    I've just listened to Steve Gibson talk about his SpinRite software, on the Security Now podcast episode 336 (transscript). At 33:20 he says: I can show and do show on the SMART page that sectors are being relocated and that errors are being corrected. That SMART analysis page sometimes scares people because it shows, wait a minute, this thing says we're correcting so many errors per megabyte. What is this SMART page? 1) Some information saved on the HD by SMART, that I can access with a SMART tool like smartmontools? 2) A page (tab) in his SpinRite software? In any case, can I see, in any way, what sectors are marked as bad, without using SpinRite? Preferably using smartmontools!
