  • Javascript widgets: do links count as SEO backlinks? [closed]

    - by j0nes
    Possible Duplicate: How good is it for SEO if you have a widget that lives on other sites? On my website I offer an option to let users embed information from my site with some kind of "homepage widget". If a user wants to embed it in his website, he basically has to add one line of Javascript to his HTML files like this: <script src="http://mysite.com/myscript.php?some_options_here"></script> Inside the widget, I export some content from my website and of course create a link back to my website. This is done in Javascript with document.write. document.writeln("My great exported content"); document.writeln('<a href="http://mysite.com?ref=widget>Check mysite.com</a>'); I have Google Analytics set up to track whether the links in there get clicked, and they do. Now I am asking myself if Google recognizes these links as valid backlinks from the embedding domain. I know that Googlebot can parse and execute Javascript, but I have not found any references whether these links also count as "normal" backlinks.

  • Is my client correct that I cannot take a vacation as a subcontractor? [closed]

    - by Rae Ann
    I have 2 clients who I do ongoing work for as a subcontractor. Both are sporadic and part-time. Company A sent me to a 3 day certification course out of state. The following week I was scheduled for a 3 day vacation. I warned company B three weeks prior to these events. During my training that Company A was paying for, Company B asked me to leave the training to workon something for them that needed immediate attention. I declined. However I made arrangements to work on it in the evening and in the early mornings after they threatened to take the work and all subsequent work for this client to someone else. I lost all networking and fun from that trip... The following week I was in Florida and was again asked to do more work on the project after the feedback from the client. The integrated product personnel would not cooperate/return any of our calls so I did the best I could. I turned in the work, explained the issue and then was gone for 3 hours. When I returned, all my access to the project had been revoked and after a week of my calls and emails I found out they replaced me. I sent an invoice 3 weeks ago and they tell me they owe me nothing because I did not do the whole project and they cannot bill the client for what I did, because they are billing for the second contractor who started over. I was told that they realize I was on vacation but as a subcontractor I lose the ability to just disappear. I was gone 3 hours! Is this normal, correct, legal?? Not only did they ruin my class and my vacation, but now they expect me to not demand payment? They ended our relationship and I was in the middle of another project of theirs too. They told me to immediately cease all work for them. How do I get paid for the work I have yet to invoice this month?

  • Anyone can suggest some Game Frameworks for GNU/Linux? [closed]

    - by dysoco
    So I've been developing a little bit with XNA + C# in Windows, not really much: just some 2D stuff, but I've found that XNA is a really good framework. I'm a GNU/Linux user, and I'm definitely migrating my desktop to Gentoo Linux (I've been using Arch in my laptop for a while now). But, of course, I need a C# + XNA alternative... I'm not really an expert in any language, so I can really pick up anything (except, maybe, Functional ones), I prefer C-Like languages like Java or Ruby, I tried Python but found the Whitespace syntax confusing. I would like to hear some of you'r suggestions, I'm not asking for "the best", but for "some suggestions", so I think this is objective enough. Probably you're going to suggest C++ + SDL, but I would prefer something more "High Level" like XNA, but I'm open to discuss anything. So... any ideas ? Note: I think this questions meets the guidelines for this site, if it doesn't: please not only downvote this question, but comment on what can I do to improve it. Thanks. PS: 2D Games, not 3D

  • I am not the most logically-organized person. Do I have any chance at being a good 'low-level' programmer?

    - by user217902
    Background: I am entering college next year. I really enjoy making stuff and solving logical problems, so I'm thinking of majoring in compsci and working in software development. I hope to have the kind of job where I can work with implementing / improving algorithms and data structures on a regular basis.. as opposed to, say, a job that's purely concerned with mashing different libraries together, or 'finding the right APIs for the job'. (Hence the word 'low-level' in the title. No, I don't wish to write assembly all day.) Thing is, I've never been the most logically-sharp person. Thus far I have only worked on hobby projects, but I find that I make the silliest of errors ever so often, and it can take me ages to find it. Like anywhere between three hours to a day to locate a simple segfault, off-by-one error, or other logical mistake. (Of course, I do other things in the meantime, like browsing SO, reddit, and the like..) It's not like I'm 'new' to programming either; I first tried C++ maybe five years ago. My question is: is this normal? Should a programmer with any talent solve it in less time? Having read Spolsky's Smart and gets things done, where he talks about the large variance in programming speed, am I near the bottom of the curve, and therefore destined to work in companies that cannot afford to hire quality programmers? I'd like to think that conceptually I'm okay -- I can grasp algorithms and concepts pretty well, I do fine in math and science, although I probably drop signs in my equations more often than the next guy. Still, grokking concepts makes me happy, and is the reason why I want to work with algorithms. I'm hoping to hear from those of you with real-world programming experience. TL;DR: I make many careless mistakes, should I not consider programming as a career?

  • How to learn to deliver quality software designs when working on a tight deadline?

    - by chester89
    I read many books about how to design great software, but I kind of struggle to come up with a good design decisions when it comes to business apps, especially when the timeframe is tough. In the company I currently work for, the following situation happen all the time: my teamlead tells me that there's a task to do, I call some guy or a girl from business who tells me exactly what is it they want, and then I start coding. The task always fits in some existing application (we do only web apps or web services), usually it's purpose is to pull data from one datasource and put into the other one, with some business logic attached in the process. I start coding and then, after spending some time on a problem, my code didn't work as expected - either because of technical mistake or my lack of knowledge of the domain. The business is ringing me 2-3 times a day to hurry me up. I ask my team lead to help, he comes up, sees my code and goes like 'What's this?'. Then he throws away about half of my code, including all the design decisions I made, writes 2-3 methods that does the job (each of them usually 200-300 lines long or more, by the way), and task is complete, code works as it should have. The guy is smarter than me, obviously, and I'm aware of that. My goal is to be better software developer, that means write better code, not finish the job quicker with some crappy code. And the thing is, when I have enough time to tackle a problem, I can come up with a design that is good (in my opinion, of course), but I fall short to do so when I'm on a tight deadline. What should I do? I am fully aware that it's rather vague explanation, but please bear with me

  • The Increasing Focus on Architecture

    - by Bob Rhubart
    If you follow my updates on Twitter or on the OTN ArchBeat page on Facebook you have probably noticed that I'm a regular reader of Joe McKendrick's SOA blog on ZDNet. Usually I'm content to simply share a link on my social networks when I find one of McKendrick's posts interesting. But with a recent post, In the cloud era, let's start calling IT what it is: 'Innovation Team', McKendrick hit on a point that warrants more than a quick link: "IT is no longer just a department full of people who code, build and maintain systems. IT is the business partner that plans and strategizes what types of technology solutions the business needs to move forward." Of course, what McKendrick is describing is an increased focus on architecture. Assuming that McKendrick's assessment is correct — and I do — that expanding focus, from coding, building, and maintaining systems to planning and strategizing technology solutions that serve the business, isn't limited to the organizational level. The individual roles within the IT organization will also have to shift to a more broadly architectural mindset. McKendrick's post references Dr. Irving Wladawsky-Berger's assessment of cloud computing as a critical "third model" of computing to emerge in the 50-year history of Information Technology. As computing itself evolves, the underlying roles that make computing possible must evolve accordingly. That evolution will be defined by an increased focus on architecture.

  • Lots of goodies

    - by wcoekaer
    We just issued a press release with a number of very good updates for everyone There are a few things of importance : 1) As of right now, Oracle Linux 6 with the Unbreakable Kernel is certified with a number of Oracle products such as Oracle Database 11gR2 and Oracle Fusion Middleware. The certification pages in the Oracle Support portal will be updated with the latest certification status for the various products. As always we have gone through a long period of very comprehensive testing and validation to ensure that the whole stack works really well together, with very large database workloads, middleware application workloads etc. 2) Standard certification efforts for Oracle Linux 6 with the Red Hat Compatible Kernel are in progress and we expect that to be completed in the next few months. Because of the compatibility between OL6 and RHEL6 we can then also state certification for RHEL6. 3) Oracle Linux binaries (and of course source code) have been free for download -and- use (including production, not just trial periods) since day one. You can freely redistribute the binaries, unlike many other Linux vendors where you need to pay a support subscription to even get access to the binaries. We offered both the base distribution release DVDs (OL4, OL5, OL6) and the update releases, such as 5.1, 5.2 etc. this way. Today, in this announcement, we also started to make available the bugfix and security updates released in between these update releases. So the errata streams (both binary and source code) for OL4, 5 and 6 are now free for download and use from http://public-yum.oracle.com. This includes uek and uek2. The nice thing is, if you want a complete up to date system without support, use this, if you then need support, get a support subscription. Simple, convenient, effective. We have great SLA's in producing our update streams, consistency in release timing and testing of all the components. Have at it!

  • .htaccess causes 403 error

    - by erdomester
    I have a working website on a free shared server. I decided to hire a dedicated server and purchase a domain for my website. I started uploading the files but things aren't working the way they should. First of all .htaccess is not working, however I set AllowOverride from None to All in /etc/apache2/sites-available/default DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> I restarted the server of course. I enabled mod_rewrite: a2enmod rewrite and restarted the server. This change causes a 403 forbidden access error which I am unable to work out. If I change the All back to None then .htaccess is ignored so instead of loading the website the file hierarchy is loaded (the main page is index4.php which should be opened by .htaccess). If I rename index4.php to index.php the website loads, just fyi. The permissions on the file is 600. If I change it to 444 I get 500 Internal Server Error. I checked the logs and I see many errors of this: Permission denied: file permissions deny server access: /var/www/index.html

  • Registering in the iOS developer program as a minor

    - by maxluzuriaga
    Hi there. Recently I started learning to develop Apps for iOS, and while the simulator is fine for starting out, I've gotten to the point that I really should be testing the Apps I write on an actual device. As I'm sure you are well aware, to do this you must be a member of the $99/year iOS developer program, which also allows you to publish on the App Store. I'm more than happy to pay the fee, but my problem is that I'm still a minor, and to join the developer program you must be over 18 in the U.S. (I'm not sure how it works in other countries). I've talked to a few others that were in a similar position, but their responses have been varied. From what I've gathered, the best course of action is to register in the name of one of my parents. My problem with this is that if I were to ever publish an App on the store, it would be ideal to have my name as the seller instead of my Dad's. It wouldn't be the end of the world if this happened, but as I said, this wouldn't be ideal. Now I turn to you; is this a good plan? Have any of you been in this position or known somebody who has? Any other tips would be greatly appreciated. Thanks!

  • How can find out the device Id of my unmounted DVD?

    - by fred.bear
    When I put a DVD into the DVD drive, it appears in Nautilus Places, but is not automatically mounted. (this is by personal choice). In this unmounted state, mount (of course) reports nothing, and likewise for df.. but Nautilus is aware of the DVD hardware unit and has read the Label; which it shows in Places So it seems to me that Nautilus has already accessed the DVD devices (Did it temporarily mount it?)... The main point of my question was to determine how to find the device Id of an unmounted device .. but as I've been writing this, I now think it may not be as simple as that... This issue came up because I wanted to test this command cat iso-pieces.* | growisofs -Z /dev/dvd=/dev/stdin, but then realized that I didn't know how to get my DVD's device Id. ... and does the above command requires a mounted device, or does it write directly to the device? ... as you can see, I'm a bit vague about devices :) Come to think of it maybe Nautalus read the DVD device directly, because when all is said and done, something has to read/write directly to it. info growisofs says: Under Linux it will most likely be an ide-scsi device such as "/dev/scd0 How can I find this Id via a script?

  • How should I structure the implementation of turn-based board game rules?

    - by Setzer22
    I'm trying to create a turn-based strategy game on a tilemap. I'm using design by component so far, but I can't find a nice way to fit components into the part I want to ask. I'm struggling with the "game rules" logic. That is, the code that displays the menu, allows the player to select units, and command them, then tells the unit game objects what to do given the player input. The best way I could thing of handling this was using a big state machine, so everything that could be done in a "turn" is handled by this state machine, and the update code of this state machine does different things depending on the state. However, this approach leads to a large amount of code (anything not model-related) going into a big class. Of course I can subdivide this big class into more classes, but it doesn't feel modular and upgradable enough. I'd like to know of better systems to handle this in order to be able to upgrade the game with new rules without having a monstruous if/else chain (or switch / case, for that matter). Any ideas? What specific design pattern other than MVC should I be using?

  • Why do Google search results include pages disallowed in robots.txt?

    - by Ilmari Karonen
    I have some pages on my site that I want to keep search engines away from, so I disallowed them in my robots.txt file like this: User-Agent: * Disallow: /email Yet I recently noticed that Google still sometimes returns links to those pages in their search results. Why does this happen, and how can I stop it? Background: Several years ago, I made a simple web site for a club a relative of mine was involved in. They wanted to have e-mail links on their pages, so, to try and keep those e-mail addresses from ending up on too many spam lists, instead of using direct mailto: links I made those links point to a simple redirector / address harvester trap script running on my own site. This script would return either a 301 redirect to the actual mailto: URL, or, if it detected a suspicious access pattern, a page containing lots of random fake e-mail addresses and links to more such pages. To keep legitimate search bots away from the trap, I set up the robots.txt rule shown above, disallowing the entire space of both legit redirector links and trap pages. Just recently, however, one of the people in the club searched Google for their own name and was quite surprised when one of the results on the first page was a link to the redirector script, with a title consisting of their e-mail address followed by my name. Of course, they immediately e-mailed me and wanted to know how to get their address out of Google's index. I was quite surprised too, since I had no idea that Google would index such URLs at all, seemingly in violation of my robots.txt rule. I did manage to submit a removal request to Google, and it seems to have worked, but I'd like to know why and how Google is circumventing my robots.txt like that and how to make sure that none of the disallowed pages will show up in their search results. Ps. I actually found out a possible explanation and solution, which I'll post below, while preparing this question, but I thought I'd ask it anyway in case someone else might have the same problem. Please do feel free to post your own answers. I'd also be interested in knowing if other search engines do this too, and whether the same solutions work for them also.

  • Is The Ease Of Windows Phone Development Ruining Its Image

    - by Tim Murphy
    I was reading an article on Mashable recently by a long time iPhone user who is living solely on a Lumia 920 at the moment and giving her assessment.  One thing that struck a nerve with me was her describing the Windows Phone ecosystem as immature.  She wasn’t saying this because of the number of apps or the big names like most people do.  She means the quality of the apps in the store. This hit a nerve with me.  I find it hard to believe that the majority of app on iOS are of any higher quality than any other platform.  I believe in any ecosystem you are going to find some high end, high quality apps, but the majority by default will be from people who are trying to solve a problem but do not have the resources to have top graphics and full blown testing.  There will also be a large number that are just there trying to trick you into giving up some cash. Does any of the mean that we shouldn’t take notice of this complaint?  Of course not!  We should always strive to publish the best quality apps possible.  Don’t do things like leaving default app icons and backgrounds.  Put a little effort into your design.  You should also spend as much time as possible ensuring against crashes and giving the user the best experience possible.  Think through your apps organization and navigation.  Go the extra step of putting it into beta and letting select people use it and give you feedback before going to full release. Remember, if we want people to appreciate the Windows Phone platform we have to make sure we give them apps that they are going to enjoy using. del.icio.us Tags: Windows Phone,iPhone,iOS,Nokia,Lumia 920,Mashable

  • I've got my Master's in Software Engineering... Now what? [closed]

    - by Brian Driscoll
    Recently I completed a Master of Science in Software Engineering from Drexel University (Philadelphia, PA, US), because I wanted to have some formal education in software (my undergrad is in Math Ed) and also because I wanted to be able to advance my career beyond just programming. Don't get me wrong; I love to code. I spend a lot of my spare time coding. However, for me writing code is just a means to an end: what I REALLY love is designing software. Not visual design, mind you, but the architecture of the system. So, ideally I'd like to try to get a job doing software architecture. The problem is that I have no real experience in it besides my graduate course work. So, what should I do to make my "bones" in software architecture? UPDATE Just so it's clear, I have over 5 years of work experience in software development and an MCTS cert in addition to my education, so I'm not looking for the usual "I'm fresh out of school, what should I do?" advice.

  • OpenGL : sluggish performance in extracting texture from GPU

    - by Cyan
    I'm currently working on an algorithm which creates a texture within a render buffer. The operations are pretty complex, but for the GPU this is a simple task, done very quickly. The problem is that, after creating the texture, i would like to save it. This requires to extract it from GPU memory. For this operation, i'm using glGetTexImage(). It works, but the performance is sluggish. No, i mean even slower than that. For example, an 8MB texture (uncompressed) requires 3 seconds (yes, seconds) to be extracted. That's mind puzzling. I'm almost wondering if my graphic card is connected by a serial link... Well, anyway, i've looked around, and found some people complaining about the same, but no working solution so far. The most promising advise was to "extract data in the native format of the GPU". Which i've tried and tried, but failed so far. Edit : by moving the call to glGetTexImage() in a different place, the speed has been a bit improved for the most dramatic samples : looking again at the 8MB texture, it knows requires 500ms, instead of 3sec. It's better, but still much too slow. Smaller texture sizes were not affected by the change (typical timing remained into the 60-80ms range). Using glFinish() didn't help either. Note that, if i call glFinish() (without glGetTexImage), i'm getting a fixed 16ms result, whatever the texture size or complexity. It really looks like the timing for a frame at 60fps. The timing is measured for the full rendering + saving sequence. The call to glGetTexImage() alone does not really matter. That being said, it is this call which changes the performance. And yes, of course, as stated at the beginning, the texture is "created into the GPU", hence the need to save it.

  • How do you tell if advice from a senior developer is bad?

    - by learnjourney
    Recently, I started my first job as a junior developer and I have a more senior developer in charge of mentoring me in this small company. However, there are several times when he would give me advice on things that I just couldn't agree with (it goes against what I learned in several good books on the topic written by the experts, questions I asked on some Q&A sites also agree with me) and given our busy schedule, we probably have no time for long debates. So far, I have been trying to avoid the issue by listening to him, raising a counterpoint based on what I've learned as current good practices. He raises his original point again (most of the time he will say best practice, more maintainable but just didn't go further), I take a note (since he didn't raise a new point to counter my counterpoint), think about it and research at home, but don't make any changes (I'm still not convinced). But recently, he approached me yet again, saw my code and asked me why haven't I changed it to his suggestion. This is the 3rd time in 2--3 weeks. As a junior developer, I know that I should respect him, but at the same time I just can't agree with some of his advice. Yet I'm being pressured to make changes that I think will make the project worse. Of course as an inexperienced developer, I could be wrong and his way might be better, it may be 1 of those exception cases. My question is: what can I do to better judge if a senior developer's advice is good, bad or maybe it's (good but outdated in today context)? And if it is bad/outdated, what tactics can I use to not implement it his way despite his 'pressures' while maintaining the fact that I respect him as a senior?

  • The SQL Server Setup Portal

    - by BuckWoody
    One of the tasks that takes a long time for the data professional is setting up SQL Server. No, it isn’t that difficult to slide a DVD in a drive and click “Setup” but the overall process of planning the hardware and software environment, making decisions for high-availability, security and dozens of other choices can make the process more difficult. And then, of course, there are the inevitable issues that arise. Microsoft supports literally hundreds and even thousands of combinations of hardware and software drivers from vendors you’ve never even heard of. Making all of that work together is a small miracle, so things are bound to arise that you need to deal with. So, to help you out, we’ve designed a new “SQL Server Setup Portal”. It’s a one-stop-shop for everything you need to know about planning and setting up SQL Server. As time goes on you’ll see even more content added. There are already whitepapers, videos, and multiple places to search on everything from topic names to error codes. So go check it out – and if you have to do a lot of SQL Server Setups – and especially if you don’t – bookmark it as a favorite!

  • Developing with Oracle ADF Mobile and ADF Business Components Backend

    - by Shay Shmeltzer
    It's great to finally have the Oracle ADF Mobile solution out there. If you are not familiar with ADF Mobile - it basically lets you build applications that run on iOS and Android devices using the concepts you already know - components based UI constructions (same idea as JSF), taskflows, data controls, Java and of course JDeveloper. I created one demo that shows how to build an on-device application that gets data from local Java files (that run on the device - yes we do Java on iOS too) - you can see it here. However, one thing many of you might be wondering is how can you get data from your database into these mobile applications. Well if you already built your data access with Oracle ADF Business Components then here is a two step video demo that shows you what to do. The steps are: 1. Expose ADF Business Components as Services 2. Create an ADF Mobile application that consumes the above services with the Web service data control Simple right? That's the whole point of ADF Mobile - making on device application development as simple as possible. Try it out on your device.

  • Late feedback

    - by Sveta Smirnova
    MySQL Community team asked me to write about Devconf 2013 few months ago. Conference was in June, 2013, but I remembered about this my promise only now: month later after my participating in MySQL Connect and Expert Troubleshooting seminar (change country to United Kingdom if you see blank page). I think it is too late for the feedback, but I still have few thoughts which I want to record.DevConf (former PHPConf) always was a place where I tried new topics. At first, because I know audience there very well and they will be bored if I repeat a story which I was telling last year, but also because it is much easier to get feedback in your own native language. But last years my habit seems started to change and I presented improved version of my 2012 MySQL Connect talk about MySQL backups. Of course, I also had a seminar with unique topic, made for this conference first time: Troubleshooting MySQL Performance with EXPLAIN and Using Performance Schema to Troubleshoot MySQL. And these topics, improved, were presented at the expert seminar. It is interesting how my habit changes and one public speaking activity interferes next one.What is good about DevConf is it forces you to create new ideas and do it really well, because audience is not forgiving at all, so they catch everything you miss or prepared not good enough. This can be bad if you want to make a marketing-style topic for free, but allows to present technical features in really good details: all these sudden discussions really help.In year 2013 Oracle had a booth at the conference and was presented by a bunch of people. Dmitry Lenev presented topic "New features of replication in MySQL 5.6" and Victoria Reznichenko worked on the booth. What was new at the conference this year is greater interest in NoSQL, scale and fast development solutions. This, unfortunately, means not so huge interest in MySQL as it was earlier. However, at the same time, "Common" track was really MySQL track: not only Oracle, but people from other companies presented about it.

  • MS Marketing Strategy

    - by Aaron Kowall
    I found this week’s Windows Phone 8 event interesting.  Not just because it looks like some fantastic new features in the new OS but because of the wait for release.  If I were a Nokia shareholder (which I am not) I’d be very unhappy with MS announcing that Windows Phone 8 will NOT work with current hardware.  So, there are some very nice Lumia devices that are now end-of-life that have arrived relatively recently at carriers and retailers. I understand that MS needs to demonstrate progress against iOS and Android and that there is some Windows 8 tie-in that they are trying to capitalize (and MS IS still all about Windows).  However, it’s a bit of a kick to partners that have invested in the platform with pretty decent devices (Samsung, HTC and of course Nokia). Personally, I’m still using a Samsung Foucs.  I was seriously considering upgrading to a Lumia 900 (we just got Lync mobile available) but will now wait it out until new devices arrive with Windows 8.  If MS had waited to announce, I would happily have upgraded to the Lumia and when I found out it couldn’t be upgraded then that would be a gamble I took and lost and I’d live with it.  Now, however, I can see the future and know that waiting is the better option for me so that is 1 sale Nokia will miss out on.  Based on some chats I’ve seen on mobile forums I’m certainly far from the only one. I’m sure glad I’m not in charge of marketing at MS.  There are tough decisions to be made there and I’m pretty sure you piss somebody off regardless. Technorati Tags: WP8,Lumia,Nokia,Samsung

  • How to run sudo command with no password?

    tl;dr: How does the ubuntu user on the AWS images for Ubuntu Server 12.04 have passwordless sudo for all commands when there is no configuration for it in `/etc/sudoers'? I'm using Ubuntu server 12.04 on Amazon. I want to add a new user that has the same behaviour as the default ubuntu user. Specifically I want passwordless sudo for this new user. So I've added a new user and went to edit /etc/sudoers (using visudo of course). From reading that file it seemed like the default ubuntu user was getting it's passwordless sudo from being a member of the admin group. So I added my new user to that. Which didn't work. Then I tried adding the NOPASSWD directive to sudoers. Which also didn't work. Anyway, now I'm just curious. How does the ubuntu user get passwordless privileges if they aren't defined in /etc/sudoers. What is the mechanism that allows this?

  • JQueryMobile - Problems with dialog boxes [closed]

    - by Richard van Hees
    I'm programming in JQueryMobile, but I can't seem to get some things as I want. First it's good to tell I am mostly programming in a multi-page template. I have a login function in the web based app. The idea is that the user sees he's not logged in and the user can click on the button to log in. A dialog box pops up, in which the user can enter his credentials. This dialog box is in front of the previous page, in my case just index.php. The page for profile is at profile.php#profile. In this case the url for the dialog box is index.php#profile&ui-state=dialog. Don't ask me why, that's how JQueryMobile works, I guess. Anyway, after the user clicks on 'Login' in the pop-up, I want a new dialog to pop-up in which it says you are logged in and I want the content of the page behind it (index.php#profile) to refresh. Of course I want this all to move very smooth and no refreshing of the whole page, to prevent loading time and thus a blank screen for a second. In short: User not logged in Clicks on login Dialog pops up with form Clicks login New dialog pops up with 'success' (or whatever) in the same style as the previous dialog Clicks ok Page behind the dialogues has been refreshed without user noticing Also another thing that doesn't really work out for me: I can't seem to get a dialog to pop up, triggered by an action in another dialog. It just appears as a normal page.

  • How do spambots work?

    - by rlb.usa
    I have a forum that's getting hit a lot by forum spambots, and of course the best way to defeat something is to know thy enemy. I'll worry about defeating those spambots later, but right now I'd like to know more about them. Reading around, I felt surprised about the lack of thorough information on the subject (or perhaps my ineptness to input the correct search terms for better google results). I'm interested in learning all about spambots. I've asked on other forums and gotten brush-off answers like "Spambots are always users registering on your site." How do forum spambots work? How do they find the 'new user registration' page? (I'm especially surprised because some forums don't have a dedicated URL for this eg, www.forum.com/register.html , but instead use query strings or even other methods invisible to the URL bar) How do they know what to enter into each 'new user registration' field? How do they determine what's a page they can spam / enter data into and what is not? Do they even 'view' this page at all? ..If not, then I'd assume they're communicating with the server directly - how is - this possible? How do they do it? Can forum spambots break CAPTCHAs? Can they solve logic questions (how?)? Math questions? Do they reverse-engineer client-side anti-bot validation scripts? Server-side scripts? What techniques are still valid to prevent them? Where do spambots come from? Is someone sitting behind the computer snickering as they watch their bot destroy site after site? Or are they snickering as they simply 'release' it onto the internet somehow? Are spambots 'run' by an infected computer somewhere? Do they replicate themselves? etc

  • TFS API The All New Team Project Picker &ndash; Beautiful!

    - by Tarun Arora
    The Team Project Picker in TFS 2011 looks gorgeous. I specially like the status bar on the working state, at least let’s you know that the project picker is still working on getting the details and of course the new icons for team project collection and team projects are stunning too.     How do I get the Team Project Picker using the TFS API? That is fairly straight forward. Add a reference to the Microsoft.TeamFoundation.Client dll available in C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0 and use the below code, public void ConnectToTfs() { TeamProjectPicker tfsPP = new TeamProjectPicker(TeamProjectPickerMode.MultiProject, false, new UICredentialsProvider()); tfsPP.ShowDialog(); }   Download a sample application here Why does my project picker look different? You might run into an issue, where the project picker looks like the below, When the Team Project Picker is run from inside of VS the colour theme will be picked up from VS itself. When running outside of VS the windows theme colours are used, so there can be differences between the two. Currently there isn’t a way to change that since the dialog itself is not public (just the wrapper that launches the dialog). So don’t be surprised if the Team Project Picker looks different then expected :-]
