  • Resources for up-to-date Delphi programming

    - by Dan Kelly
    I'm a developer in a small department and have been using Delphi for the last 10 years. Whilst I've tried to keep up-to-date with movements there are a lot of changes that have occurred between Delphi 7 and (current for us) 2010. Stack Exchange and here have been great for answering the "how do you" questions, but what I'd like is a resource that shows great examples of larger scale programming. For example is there anywhere that hosts examples of well written, multi form applications? Something that can be looked at as a whole to illustrate why things should be done a certain way?

  • What resources are there for facial recognition

    - by Zintinio
    I'm interested in learning the theory behind facial recognition software so that I can hopefully implement it in the future. Not just face tracking, but being able to recognize individuals. What papers, books, libraries, or source is available so that I can learn more about the subject? I have found libface which seems to use eigenfaces for recognition. If there are any practitioners out there, please share any information that you can.

  • Avoid double compression of resources

    - by user1095108
    I am using .pngs for my textures and am using a virtual file system in a .zip file for my game project. This means my textures are compressed and decompressed twice. What are the solutions to this double compression problem? One solution I've heard about is to use .tgas for textures, but it seems ages ago, since I've heard that. Another solution is to implement decompression on the GPU and, since that is fast, forget about the overhead.

  • How should I handle missing resources?

    - by concept3d
    Your game expects a certain asset to be loaded, but it isn't found. How should the situation be handled? For example: Texture* grassTexture = LoadTexture("Grass.png"); // returns NULL; texture not found Mesh* car = LoadMesh("Car.obj"); // returns NULL; 3D mesh not found It might have been accidentally deleted by the user, corrupted or misspelled while in development. Some potential responses: Assertions (ideally only during development) Exit the game gracefully Throw an exception and try to handle it. Which way is best?

  • Any algorithm to dedicate a set of known resources to a set of known requirements (scheduling)

    - by Saeed Neamati
    I'm developing an application to help school principals in dedicating teachers to classes and courses over the hours of a week (scheduling). The scenario is roughly something like this: User enters the list of teachers and their free times into the system User enters the list of courses for this semester User enters the list of available classes into the system Well, up to here, there is no big deal. Just simple CRUD operations and nothing extraordinary. However, now what makes this system useful is that the application should automatically and based on an algorithm create the semester scheduling. I think you've got the main idea here. For example application should suggest that teacher A should go to class 1 for mathematics, and at the same time teacher B should go to class 2 for physics. This way all of the classes would be dedicated to lessons and teacher times won't overlap each other. Piece a cake for school principal. However, I can't find a good algorithm for this resource dedication. I mean it seems hard to me. Searching Google resulted in articles from different websites, but they are of no help and use to me. For example: http://en.wikipedia.org/wiki/Resource_allocation or http://en.wikipedia.org/wiki/Scheduling_(production_processes) Is there any algorithm out there, or any application or engine which can help me here? Does this requirements have a known name, like for example time scheduling engine? Any help would be appreciated.

  • WWDC and Tech Ed: A Tale of Two DevCons

    - by andrewbrust
    Next week marks the first full week of June.  Summer will feel in full swing and it will be a pretty big season for technology.  In seeming acknowledgement of that very fact, both Apple and Microsoft will be holding large developers conferences starting Monday.  Apple will hold its annual Worldwide Developers Conference (WWDC) in lovely San Francisco and Microsoft will hold its Tech Ed conference in muggy, oil-laden yet soulful New Orleans.  A brief survey of each show reveals much about the differences in each company’s offerings, strategy, and approach to customers and partners. In the interest of full disclosure, I must explain that I will be speaking at Microsoft’s Tech Ed show, and have done so, on and off, since 2003.  I have never been to an Apple conference and, as readers of this blog may know, I acquired my first ever Apple product 2 months ago when I bought an iPad on the day of that product’s launch.  I think I have keen insights into Microsoft’s conference.  My ability to comment on Apple’s event ranges somewhere between backseat driver and naive observer.  Just so you know. Although both shows cater to their respective company’s developers, there are a number of differences in the events’ purposes and content approaches.  First off, let’s consider each show as a news and PR vehicle.  WWDC will feature Steve Jobs’ keynote address and most likely will be where Apple officially reveals details of its 4th-generation iPhone. Jobs will likely also provide deep background information on the corresponding iPhone OS release.  These presumed announcements will make the show a magnet for the tech press and tech blogger elite.  Apple’s customers will be interested too, especially since the iPhone OS release will likely be made available to owners of existing iPhone, iPod Touch and iPad devices. Tech Ed, on the other hand, may not be especially newsworthy at all.  The keynote address will be given by Bob Muglia, who is President of the company’s Server and Tools Division, and he’ll likely be reviewing things more than previewing them. That’s because the company has, in the last 6-8 months, already released new versions of a majority of its products, including Windows, Office, SharePoint, SQL Server, Exchange, its Azure cloud platform, its .NET software development layer, its Silverlight Rich Internet Application (RIA) technology and its Visual Studio developer suite.  Redmond’s product pipeline has functioned more like a firehose of late, and the company has a ton of work to do to get developers up to speed on everything that’s new. I know I keep saying “developers,” but in Tech Ed’s case, that’s not really accurate.  In North America, Tech Ed caters to both developers and IT pros (i.e. technologists who work with physical IT infrastructure, as well as security and administration of the server software that runs on it).  This pairing has, since its inception, struck some as anomalous and others, including many exhibitors, as very smart. Certainly, it means Tech Ed ends up being a confab for virtually all professionals in Microsoft’s ecosystem.  And this year, Microsoft’s Business Intelligence (BI) conference will be co-located with Tech Ed, further enhancing that fusion effect. Clearly then, Microsoft’s show will focus on education, as its name assures us.  Apple’s will serve as both a press event and an opportunity to get its own App Store developer channel synced up with its newest technology advances.  For example, we already know that iPhone OS 4.0 will provide for a limited multitasking capability; that will only work well if people know how to code to it in a capable way.  Apple also told us its iAd advertising platform will be part of the new OS, and Steve Jobs insists that’s to provide a revenue opportunity for developers.  This too, then, needs to be explicated and soaked up buy the faithful. A look at each show’s breakout session lineup provides some interesting takeaways.  WWDC will have very few Mac-specific sessions on offer, and virtually no sessions that at are IT- or “Enterprise-“ related.  It’s all about the phone, music players and tablets.  However, WWDC will have plenty of low-level, hardcore tech coverage of such things as Advanced Memory Analysis and Creating Secure Applications, as well as lots of rich media-related content like Core Animation and Game Design and Development.  Beyond Apple’s proprietary platform, WWDC will also feature an array of sessions on HTML 5 and other Web standards.  In all, WWDC offers over 100 technical sessions and hands-on labs. What about Tech Ed’s editorial content?  Like the target audience, it really runs the gamut.  The show has 21 tracks (versus WWDC’s 5) and more than 745 “learning opportunities” which include breakout sessions, demo stations, hands-on labs and BIrds of a Feather discussion sessions.  Topics range from Architecture talks like Patterns of Parallel Programming to cloud computing talks like Building High Capacity Compute Applications with Windows Azure to IT-focused topics like Virtualization of Microsoft SharePoint 2010 Farm Architecture.  I also count 19 sessions on Windows Phone 7.  Unfortunately, with regard to Web standards and HTML 5, only a few sessions are offered, all of them specific to Internet Explorer. All-in-all, Apple’s show looks more exciting and “sexier” than Tech Ed. Microsoft’s show seems a lot more enterprise-focused than WWDC. This is, of course, well in sync with each company’s approach and products.  Microsoft’s content is much wider ranging and bests WWDC in sheer volume of sessions and labs.  I suppose some might argue that less is more; others that Apple’s consumer-focused offerings simply don’t provide for the same depth of coverage to a business audience.  Microsoft has a serious focus on the cloud and  a paucity of coverage on client-side Web standards; Apple has virtually no cloud offering at all.  Again, this reflects each tech titan’s go-to-market strategy. My own take is that employees of each company should attend the other’s event.  The amount of mutual exclusivity in content may make sense in terms of corporate philosophy, but the reality is that each company could stand to diversify into the other’s territory, at least somewhat. My own talk at Tech Ed will focus on competitive analysis around Microsoft’s BI products.  Apple does not today figure into that analysis. Maybe one day it will.

  • General purpose ticketing/tech support system [closed]

    - by crazybyte
    Possible Duplicate: What’s your favorite ticketing system? I was wondering if somebody could recommend me a very user friendly or simple general purpose ticketing/tech support system. I need something that is web based, preferably open-sourced/free software implemented using PHP, Ruby, Ruby on Rails or Java (as back end) with MySQL or PostgreSQL as database engine. I need something that is not development management oriented or project management oriented like Eventum or similar (random example), something to which the user can connect open a tech support request and be able to follow it until is solved or dropped.I need it to be open-sourced to be able to modify it if there is a need or extend it. I tried a number of such systems available and I found that osTicket or eTicket is something that it's close to what I need, but the code is somewhat flaky and some of the features are working badly or behaving strangely. Any thoughts/advice where to find something similar? Thanks!

  • What do you consider to be a high-level language and for what reason?

    - by Anto
    Traditionally, C was called a high-level language, but these days it is often referred to as a low-level language (it is high-level compared to Assembly, but it is very low-level compared to, for instance, Python, these days). Generally, everyone calls languages of the sort of Python and Java high-level languages nowadays. How would you judge whether a programming language really is a high-level language (or a low-level one)? Must you give direct instructions to the CPU while programming in a language to call it low-level (e.g. Assembly), or is C, which provides some abstraction from the hardware, a low-level language too? Has the meaning of "high-level" and "low-level" changed over the years?

  • Company Administrators: Stay Alert!

    - by Pete
    Some of our customers choose to use the Themes feature to rebrand their Training and Support Center link, and redirect it to an internal support site. If your company does this, we strongly advise that for your employees that have the Administrator role, you maintain a separate theme that keeps the Administrator's Training and Support link pointed to the CRM On Demand Training and Support Center, and not redirect it to an internal support site. Why? The company administrator needs access to the Training and Support Center because it gives them pod-specific application alerts on the Support tab and pod-specific release information on the Release Info tab. If a customer no longer has access to the Training and Support Center URL because they have already rebranded that link, they can contact Customer Care to request it again.

  • How to force high-dpi scaling?

    - by Ian Boyd
    How can i force an application to be high-dpi scaled? Or alternatively, how can an application that is not manifested as high-dpi aware, and doesn't have dpi-scaling disabled from the Properties-Compatibility tab, not be scaled? Pretend i have an application, who's developers decided to manifest it as high-dpi aware, when it really isn't. How can i force dpi-scaling? Pretend i have an applicaiton that Microsoft has applied the "HighDpiAware" compatiblity shim to, when the application really isn't. How can i force dpi-scaling? Pretend i have an application (i.e. Shareaza) that does not have a dpi-aware manifest, does not disable dpi-scaling from the application's Properties tab, but high-dpi scaling is not being applied? How can i force it? How can i force Windows to apply dpi-scaling to an application? See also

  • Scalable WordPress Host for High-Volume Site?

    - by Jonathan Eunice
    I need recommendations for a scalable web host for a high volume WordPress web site. For my purposes, high-volume might be 100K-500K visitors/hour. Might think towards a 1M/hour burst rate as a "high water mark." I know WP isn't the highest-performing platform out there (ha!), but it's non-negotiable. I can do "the usual optimizations" (e.g. put static files in a CDN, run and follow the advice of performance analyzers like YSlow, etc). But it will still be WordPress, and there will be a dozen or so plugins involved. So, where to host the site? Most "what's the best WordPress host?" discussions seem to focus on lowest-cost. I need the opposite. What are the high-volume, scalable, or clustered WordPress hosts with which you've had great experiences?

  • Accessing network resources via vpn connection failes

    - by LikeHoo
    I already found some information on this problem here, but I still can't get it to work. Im trying to access some network resources on my server via vpn over the net. Im using a win7 home pc here and a win server 2008 rc2 with installed ras&routing role on the server. For vpn authentication I use a local user on the server with vpn-access. This user also has the rights to access to the network resources, but it neither finds the server under network nor is it able to connect the network drives... In similar topics here I found out that using the same credentials for vpn-authentication and network resources access does not work, but using different user for access didn't work either. All of these examples I found were in an active directory structure, but I don't have an active directory here. Does anyone know how to solve this problem without having to use an active directory? Thanks

  • No apparent reason for high load average

    - by Oz.
    We have several web servers running on Amazon (ec2) c1.xlarge, over Amazon AMI. The servers are duplicates of each other, running the exact same hardware and software. Each server spec is: 7 GB of memory 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) 1690 GB of instance storage 64-bit platform I/O Performance: High API name: c1.xlarge A couple of weeks ago we have run a yum upgrade on one of the servers. Starting on this upgrade the upgraded server started showing a high load average. Needless to say, we did not update the other servers and we can not do so until we understand the reason for this behavior. The strange thing is that when we compare the servers using top or iostat, we can not find the reason for the high load. Note that we have moved traffic from the "problematic" server to the others, which have made the "problematic" server less crowded in terms of requests, and still his load is higher. Do you have any idea what could it be, or where else can we check? Many thanks for the help!

  • Nginx + PHP-FPM Too Many Resources

    - by user3393046
    My Server has the following Specs CPU: 6 Cores Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz RAM: 32 GB I have a problem with nginx+php-fpm. They are taking too many resources for an unknown reason. Even if i restart the nginx + php-fpm the start up processes will use many resources. My nginx Config is the following: user nginx; worker_processes auto; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; worker_rlimit_nofile 300000; events { worker_connections 6000; use epoll; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; } My php-fpm pool config is the following [www] user = nginx group = nginx listen = /var/run/php5-fpm.sock listen.owner = nginx listen.group = nginx listen.allowed_clients = 127.0.0.1 pm = ondemand pm.max_children = 1500; pm.process_idle_timeout = 5; chdir = / security.limit_extensions = .php I'm using on pm.ondemand since my website has to support many concurrent connections at the same time and i was unable to to it with dynamic/static. I guess this isnt the problem because as i said earlier when i restart nginx+php-fpm at the same time, they are taking too much resources without any request.

  • What's the next tech bubble? [closed]

    - by jayd3e
    Today I read one of Jeff Atwood's newest blog posts entitle "Lived Fast, Died Young, Left a Tired Corpse." In the second paragraph, he mentions that: There's plenty of evidence that we're entering another tech bubble. It's just less visible to people outside the tech industry because there's no corresponding stock market IPO frenzy. Yet. I was just curious if anyone has some solid ideas as to what this next tech bubble could be?

  • Checking out systems programming, what should I learn, using what resources?

    - by Anto
    I have done some hobby application development, but now I'm interested in checking out systems programming (mainly operating systems, Linux kernel etc.). I know low-level languages like C, and I know minimal amounts of x86 Assembly (should I improve on it?). What resources/books/websites/projects etc. do you recommend for one to get started with systems programming and what topics are important? Note that I know close to nothing about the subject, so whatever resources you suggest should be introductory resources. I still know what the subject is and what it includes etc., but I have not done systems programming before (but some application development, as previously noted, and I'm familiar with a bunch of programming languages as well as software engineering in general and algorithms, data structures etc.).

  • High server load - [jbd2/md1-8] using 99.99% IO

  • Cheapest High Available Web Server [closed]

    - by xyz
    I would like to create a high-available setup (e.g. a small cluster) for a webserver, i.e. it will run Apache, PHP and MySQL. There will be between 2-8 small websites running with only very little traffic and workload. High availability is however very important. I don't want to be dependent on 1 datacenter, so there must be a minimum of 2 servers placed in different datacenters, and if one server goes down, the user must experience no or only a minimum of downtime - and no data loss. I have considered Amazon AWS using their Elastic Load Balancing, since it is possible to buy 2 EC2 instances in 2 availability zones and set up load balancing and RDS (Multi-AZ). However this seems rather expensive. Using the AWS price calculator http://calculator.s3.amazonaws.com/calc5.html it totals to 185$/month the first year (including the free tier). Are my calculations incorrect or is there a cheaper way to make this HA setup? Best regards

  • How to setup Wordpress High Availability

    - by Ketam
    I have installed Galera Cluster on 3 cluster + 1 management. I wanted to make it like this, Server1: Home (www.domain.com) Server2: For BBpress/Forum (Forum Tab Menu will forward to forum.domain.com) Server3: BuddyPress Activity (Social Tab Menu will forward to social.domain.com) The purpose I am doing this is to distribute my resource and load balancing each other at same time. However, I have difficulty to setup Apache Load-Balancing/mod_proxy/clustering or any suitable to have high availability WordPress. Any best suggestion/solution to make high availability WordPress? Or how to? And another question is I tried to copy whole WordPress files & folders to Server2 connecting to local database (same data inside since it is already on Galera Cluster) but the page blank. Any advice? OS: Centos 6.2 Thanks in advanced.

  • android - using resources drawable in content provider

    - by Russ Wheeler
    I am trying to pass back an image through a content provider in a separate app. I have two apps, one with the activity in (app a), the other with content provider (app b) I have app a reading an image off my SD card via app b using the following code. App a: public void but_update(View view) { ContentResolver resolver = getContentResolver(); Uri uri = Uri.parse("content://com.jash.cp_source_two.provider/note/1"); InputStream inStream = null; try { inStream = resolver.openInputStream(uri); Bitmap bitmap = BitmapFactory.decodeStream(inStream); image = (ImageView) findViewById(R.id.imageView1); image.setImageBitmap(bitmap); } catch(FileNotFoundException e) { Toast.makeText(getBaseContext(), "error = "+e, Toast.LENGTH_LONG).show(); } finally { if (inStream != null) { try { inStream.close(); } catch (IOException e) { Log.e("test", "could not close stream", e); } } } }; App b: @Override public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException { try { File path = new File(Environment.getExternalStorageDirectory().getAbsolutePath(),"pic2.png"); return ParcelFileDescriptor.open(path,ParcelFileDescriptor.MODE_READ_ONLY); } catch (FileNotFoundException e) { Log.i("r", "File not found"); throw new FileNotFoundException(); } } In app a I am able to display an image from app a's resources folder, using setImageURi and constructing a URI using the following code. int id = R.drawable.a2; Resources resources = getBaseContext().getResources(); Uri uri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + resources.getResourcePackageName(id) + '/' + resources.getResourceTypeName(id) + '/' + resources.getResourceEntryName(id) ); image = (ImageView) findViewById(R.id.imageView1); image.setImageURI(uri); However, if I try to do the same in app b (read from app b's resources folder rather than the image on the SD card) it doesn't work, saying it can't find the file, even though I am creating the path of the file from the resource, so it is definitely there. Any ideas? Does it restrict sending resources over the content provider somehow? P.S. I also got an error when I tried to create the file with File path = new File(uri); saying 'there is no applicable constructor to '(android.net.Uri)' though http://developer.android.com/reference/java/io/File.html#File(java.net.URI) Seems to think it's possible...unless java.net.URI is different to android.net.URI, in which case can I convert them?

  • No clue for high load average on top

    We have several machines on Amazon (ec2) of the type c1.xlarge with 16 cpus, running the Amazon AMI.

We did not yet update the other machines, and everything looks normal on them. The strange thing is that the top command not showing any hint for the cause of the load. CPUs are 4.8%us, 1.1%sy, 0.0%ni, 94.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st(see below). Mem is about 1.5GB free. Any idea what could it be, or where else can we check? Many thanks for the help. # # top # top - 07:57:42 up 4:18, 1 user, load average: 1.36, 1.45, 1.47 Tasks: 131 total, 1 running, 130 sleeping, 0 stopped, 0 zombie Cpu(s): 4.8%us, 1.1%sy, 0.0%ni, 94.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 7120092k total, 5644920k used, 1475172k free, 532888k buffers Swap: 0k total, 0k used, 0k free, 3463936k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1557 mysql 20 0 1829m 374m 6448 S 14.3 5.4 11:15.09 mysqld 6655 apache 20 0 416m 49m 3744 S 9.3 0.7 0:04.85 httpd 27683 apache 20 0 421m 54m 3708 S 9.0 0.8 0:00.99 httpd 6682 apache 20 0 424m 57m 3788 S 8.3 0.8 0:03.81 httpd 16816 apache 20 0 419m 51m 3760 S 4.3 0.7 0:04.09 httpd 22182 apache 20 0 417m 50m 3756 S 1.7 0.7 0:06.34 httpd 219 root 20 0 0 0 0 S 0.3 0.0 0:00.34 kworker/7:1 699 root 20 0 0 0 0 S 0.3 0.0 0:00.40 kworker/3:1 1 root 20 0 19376 1508 1212 S 0.0 0.0 0:00.29 init 2 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kthreadd 3 root 20 0 0 0 0 S 0.0 0.0 0:00.71 ksoftirqd/0
