• Strategy for managing lots of pictures for a website

  - by Nate

  I'm starting a new website that will (hopefully) have a lot of user generated pictures. I'm trying to figure out the best way to store and serve these pictures. The CMS I'm using (umbraco) has a media library that puts a folder on the server for each image. Inside of there you can have different sizes of that same image. That folder has an ID on it and the database has additional information for that image along with the ID of the folder. This works great for small sites, but what if the pictures get up to 10,000, 100,000 or 1,000,000? It seems like the lookup on the directory would take a long time to find the correct folder. I'm on windows 2008 if that makes a difference. I'm not so worried about load. I can load balance my server pretty easily and replicate the images across the servers. The nature of the site won't have a lot of users on it either, but it could have a lot of pics. Thanks. -Nate EDIT After some thought I think I'm going to create a directory for each user under a root image folder then have user's pictures under that. I would be pretty stoked if I had even 5,000 users, so that shouldn't be too bad of a linear lookup. If it does get slow I will break it down into folders like /media/a/adam/image123.png. If it ever gets really big I will expand the above method to build a bigger tree. That would take a LOT of content though.

• Multiple apps in one "icon" on the iPod touch [closed]

  - by Jerry

  I have researched but can't find any discussion about moving several apps into one "icon" on the iPod touch screen. I have moved 5 apps (all the same category) into one what is normally one app icon. The title on the icon reads "games" - all are games. I have all the apps jiggling and drag one game app on top of another game app - They move to be side by side and the title automatically reads "games" - is this "OK" to do - you can have nine apps in each of the 16 spaces available on each screen. Will this hurt the touch? As long as you have space (GBs) is this ok? Has anyone done or heard of this? Any help is appriecated.

• How to open ports on router for better torrent performance

  - by Mehper C. Palavuzlar

  I've been using utorrent to download and upload torrents for a long time. Recently someone told me that I need to open port(s) for utorrent from my router settings for better downloading and uploading performance. Is it true? If yes, how can I do that? My utorrent version: 2.0 and the port used for incoming connections: 61829. My router: Yaksu S200 ADSL router modem and I can reach its settings via web interface. I looked at the settings but they seem a bit complicated to me. Other info you may need to know: I have dynamic IP. I'm using Win7 x64.

• Problems installing Ruby 1.9.2 and rvm on Debian Lenny

  - by Dave Everitt

  I have currently have Ruby 1.9.1 (bad) and want to install 1.9.3 under rvm. However, rvm requirements gives a long list: install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion But I've hit a problem here: /# apt-get install libreadline6 Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package libreadline6 ...and (I imagine after just hunting down a Debian source to download curl) finding these packages isn't going to be a picnic. Given that there are few packages to install before I can get rvm to install Ruby 1.9.3, what's a good way forward? My sources.list: deb http://archive.debian.org/debian/ lenny main contrib

• Having issues using fdisk and GParted with Lexar 64GB USB, but reading and writing is fine

  - by MetaDark

  I have recently bought a new 64GB Lexar USB with the long model name of LJDV10-64G-000-106, and I am having issues partitioning it. I am able to mount, read and write to the USB without any issues but whenever I try to partition it with GParted it doesn't show up in the dropdown. Also while using the command sudo fdisk -l I receive the error fdisk: unable to seek on /dev/sdc: Invalid argument. This is a brand new USB so I am not sure why I am having these issues, especially since the device is functioning perfectly with read/write. I have tried reformatting it on a windows machine but that does not seem to do anything. For those who want a visual my USB looks almost exactly like But 64GB rather than 8GB Edit: I have just ran GParted from the terminal and I am getting a similar error, but it may give more information on the issue. Could not determine physical sector size for /dev/sdc. Using the logical sector size (512). Invalid argument during seek for read on /dev/sdc Also clearing my USB with /dev/zero fails with the the message $ sudo dd if=/dev/zero of=/dev/sdc bs=1M dd: writing `/dev/sdc': No space left on device 1+0 records in 0+0 records out 0 bytes (0 B) copied, 0.00167254 s, 0.0 kB/s

• Excel - Referring to a certain cell based off of data in another

  - by Ethan Brouwer

  I have a spreadsheet where there is one table with the headings: Coordinate, Lat, Long Another with headings Triangle, Coordinate 1, Coordinate 2, Coordinate 3, Area What this is for, is taking the triangles formed by the specified three coordinates' area based off of Girard's theorem, as they are all spherical triangles. I need to take the specific latitude and longitude values from the first table based on the coordinate numbers underneath the three coordinate headings in the second table. I hope this makes sense. Here are pictures detailing what the two tables look like: Table 1 Table 2 Thanks in advance. And I really do hope this makes sense.

• Apache2 BufferedLogs On - anybody using it ?

  - by Qiqi

  Greetings, I am wondering, whether anybody is using BufferedLogs On with Apache2 and found any issues ? Feature is marked as experimental, but for many years now, so I guess it's rather pretty stable. I am running some servers with constrained disk IO capacity at the moment, so I turned it on hoping that even a small benefit could help in the long run ;-) I do have several to several hundreds requests per seconds so by my thoughts there is really no need to write to log after each request, cause honestly I don't think that my filesystem is the best handler for many unnecessary writes. (OCFS2 shared among several DomUs in the Xen)

• RewriteRule dropping escaped parameter

  - by Gerd

  I need some help with the following RewriteRule: RewriteRule ^/iesearch/(.*)$ /jsp/search/ieaccelerators/visualsearch.jsp?q=$1 [L,PT] The intention is to rewrite search-queries from http://mydomain/iesearch/alvin+the+chip to a JSP. This works fine as long as the URL does not contain encoded characters such as: http://mydomain/iesearch/alvin+%26+the+chip. The rewrite log shows the following: (2) init rewrite engine with requested uri /iesearch/alvin+&+the+chip (2) rewrite '/iesearch/alvin+the+&+chip' - '/jsp/search/ieaccelerators/visualsearch.jsp?q=alvin+&+the+chip' (3) split uri=/jsp/search/ieaccelerators/visualsearch.jsp?q=alvin+&+the+chip - uri=/jsp/search/ieaccelerators/visualsearch.jsp, args=q=alvin+&+the+chip I would have hoped that the %26 is passed on instead of the &.

• Organising data access for dependency injection

  - by IanAWP

  In our company we have a relatively long history of database backed applications, but have only just begun experimenting with dependency injection. I am looking for advice about how to convert our existing data access pattern into one more suited for dependency injection. Some specific questions: Do you create one access object per table (Given that a table represents an entity collection)? One interface per table? All of these would need the low level Data Access object to be injected, right? What about if there are dozens of tables, wouldn't that make the composition root into a nightmare? Would you instead have a single interface that defines things like GetCustomer(), GetOrder(), etc? If I took the example of EntityFramework, then I would have one Container that exposes an object for each table, but that container doesn't conform to any interface itself, so doesn't seem like it's compatible with DI. What we do now, in case it helps: The way we normally manage data access is through a generic data layer which exposes CRUD/Transaction capabilities and has provider specific subclasses which handle the creation of IDbConnection, IDbCommand, etc. Actual table access uses Table classes that perform the CRUD operations associated with a particular table and accept/return domain objects that the rest of the system deals with. These table classes expose only static methods, and utilise a static DataAccess singleton instantiated from a config file.

• ASP.NET MVC WebService - Security for Industrial Android Clients

  - by Chris Nevill

  I'm trying to design a system that will allow a bunch of Android devices to securely log into an ASP.NET MVC REST Web service. At present neither side are implemented. However there is an ASP.NET MVC website which the web service will site along side. This is currently using forms authentication. The idea will be that the Android devices will download data from the web service and then be able to work offline storing data in their own local databases, where users will be able to make updates to that data, and then syncing updates back to the main server where possible. The web service will be using HTTPS to prevent calls being intercepted and reduce the risk of calls being intercepted. The system is an industrial system and will not be in used by the general Android population. Instead only authorized Android devices will be authorized by the Web Service to make calls. As such I was thinking of using the Android devices serial number as a username and then a generated long password which the device will be able to pick up - once the device has been authorized server side. The device will also have user logins - but these will not be to log into the web service - just the device itself - since the device and user must be able to work offline. So usernames and passwords will be downloaded and stored on the devices themselves. My question is... what form of security is best setup on the web service? Should it use forms Authentication? Should the username and password just be passed in with each GET/POST call or should it start a session as I have with the website? The Android side causes more confusion. There seems to be a number of options here Spring-Android, Volley, Retrofit, LoopJ, Robo Spice which seems to use the aforementioned Spring, Retrofit or Google HttpClient. I'm struggling to find a simple example which authenticates with a forms based authentication system. Is this because I'm going about this wrong? Is there another option that would better suite this?

• Why do some bad websites rank well?

  - by BradB

  Consider the following scenario: you are pitching SEO/Website Optimisation to a prospective client and you explain to them the importance of great copy and content, how acquiring links (ethically) can increase page rank, why the quality of the HTML build matters (H1, H2 tags, w3c validation etc), why keyword research is beneficial, you may drop in a few Google Webmaster Guideline or Matt Cutts references to back up your claims and rubbish the "back hat" approach as being no longer effective for good measure. Your advice is ethical and in the eyes of best practices, spot on. Then, the client points out to you some of their long established competitors on Google and you see these competitor websites ranking in the top spots (1 to 3) for medium to highly competitive search phrases that your client wants to compete for. These websites totally contradict your ethical approach and pretty much violate every best practice previously noted. They even out perform other "white hat" competitors who are in accordance with the above guidelines. I experienced this today. One of these well ranking websites had: About six microsites with more or less the same copy and a slightly varied layout Little or not textual content I would almost say duplicate content across the sites, but there was so little of it it could barely qualify for being duplicate All the content in Flash (with a music track that kicked in on each page load, not so much of an SEO issue - but it helps paint the picture) Keyword stuffing behind the Flash file with a bunch of black text on black background in the style of keyword 1 keyword 2,keyword1,keyword 2,keyword 2 keyword 3 and so on... The exact keyword stuffed combination present on every page of the website A bunch of clearly self made links from poor quality forums and directories with little or no Page Rank Links exchanged across the microsites How do you explain your way out of this when this hard evidence is sat in front of you undermining your great pitch?

• Video for an ads-driven web-site

  - by AntonAL

  I have a website, wich i will fill with a bunch of useful videos. I've implemented an ads rotation engine for articles and will do so for videos. The next milestone is to decide, how video will be integrated. They are two ways: To host videos myself. Pros: complete freedom. Cons: need tens of gigabytes of storage; support for multiple formats to be crossbrowser and crossdevice. Use Youtube. Pros: Very simple to use; nothing to do. What are pros and cons for each way ? Some questions for YouTube: Will i be able to control playback of YouTube-embedded video to make post-rolls ? What is ranking impact on my web-site, when most of pages will refer to YouTube ? Will, say, iPad play video, embedded via YouTube's iframe ? Does relying entirely on YouTube have a long-term perspective for a web-site, that should bring money ?

• A Year of Upheaval for Procurement Professionals-New Report & Webinar

  - by DanAshton

  2013 will see significant changes in priorities and initiatives among procurement professionals as they balance the needs of their enterprises with efforts to add capabilities for long-term procurement success. In response, procurement managers will expand their organization’s spend influence via supplier relationship management, sourcing, and category management. These findings are part of the new report, “2013 Procurement Key Issues: Going Deeper and Broader to Deliver Borderless Procurement Services,” by the Hackett Group. The authors say that compared to similar studies over the last five years, 2013 is registering the greatest year-over-year changes in priorities for both procurement performance and capability issues. Three Important PrioritiesThe survey found that procurement professionals are focusing their attention in three key areas. Cost reduction. Controlling expenses is always a high priority, but with 90 percent of the respondents now placing this at the top of their performance concerns, the Hackett analysts say this “clearly shows that, for better or worse, cost reduction is king” in 2013. Technology innovation. Innovation has shot up significantly in the priority rankings and is now tied with spend influence for second among procurement professionals. Sixty-five percent of the survey participants said pursuing game-changing innovation and technology is a top procurement initiative. Managing supply risk. This area registered a sharp rise in importance because of its role in protecting profits, Hackett says. Supplier compliance with performance milestones and regulatory requirements is receiving particular attention, with an emphasis on efficient management of cross-functional workflows. “These processes create headaches for suppliers and buyers alike, and can detract from strategic value creation when participants are bogged down in processing paper and spreadsheets,” the report explains.  For more insights into the current state of the procurement industry, download the full report, “2013 Procurement Key Issues: Going Deeper and Broader to Deliver Borderless Procurement Services” and watch a Webcast featuring Global Procurement Advisory Practice Leader for The Hackett Group, Chis Sawchuk, and Managing Supervisor of Supply Chain Processes and Systems for Ameren, Chris Nelms.

• Notepad Automatically Launches Upon Boot Up of my Windows 7 64-Bit Desktop PC

  - by Simon

  Around 12 months ago, When my Windows 7 PC boots up, Notepad started to appear automatically on the desktop (as a duplicate ie one on top of the other), both displaying the same writing inside, and the name of the Notepad was: desktop-Notepad. [.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21787 I cant remember the exact details as its been so long now but a friend told me, this was due to a "hidden attribute" belonging to notepad becoming "unhidden"and therefore showing itself on the desktop at startup. He showed me a series of steps to either hide the attribute again or to delete it ( telling me that upon restart of my computer it would be recreated/regenerated.) I did indeed follow his guidance however after trying to hide it or delete it (it was never recreated after restart which supposedly it should have done) One notepad still is autolaunched with the text as shown above everytime I startup my PC. As I found this forum I thought I might try again for a solution to prevent notepad from launching. Thankyou

• Installing isolated instance of MySQL on Windows using silent install with .msi

  - by Abram

  I'm trying to write an installer for an internal application we wrote. After it installs our application it then installs MySQL using the .msi installer in silent mode. I specify the install dir and data dir to that of a directory within my application's install directory, such as: msiexec /i @@MYSQL_INSTALLER_FILE@@ /qn INSTALLDIR="@@INSTALL_DIR@@\MySQL\" DATADIR="@@INSTALL_DIR@@\MySQL\" USERNAME="@@DB_USER@@" PASSWORD="@@DB_PASS@@" (the @@variable@@'s are replace by my installer routine using InstallJammer) Once installed, I use mysqld.exe to install a windows service with a custom service name and defaults file like so: mysqld.exe --install CustomMySQL --defaults-file="@@INSTALL_DIR@@\MySQL\my.ini" This works fine as long as there is not already another instance of MySQL installed. If there is it silently fails to install MySQL. Running the msi installer manually (double-click) shows an error that a previous version is already installed and just aborts. Is there a way to automate installing MySQL as an isolated instance, regardless of whether another version/instance is already installed?

• Recommended website performance monitoring services? [closed]

  - by Dennis G.

  I'm looking for a good performance monitoring service for websites. I know about some of the available general monitoring services that check for uptime and notify you about unavailable services. But I'm specifically looking for a service with an emphasis on performance. I.e., I would like to see reports with detailed performance statistics from multiple locations world-wide, with a break-down on how long it took to fetch the different website resources, including third-party scripts such as Google Analytics and so on (the report should contain similar details such as the FireBug Net tab). Are there any such services and if so, which one is the best?

• How to account for speed of the vehicle when shooting shells from it?

  - by John Murdoch

  I'm developing a simple 3D ship game using libgdx and bullet. When a user taps the mouse I create a new shell object and send it in the direction of the mouse click. However, if the user has tapped the mouse in the direction where the ship is currently moving, the ship catches up to the shells very quickly and can sometimes even get hit by them - simply because the speed of shells and the ship are quite comparable. I think I need to account for ship speed when generating the initial impulse for the shells, and I tried doing that (see "new line added"), but I cannot figure out if what I'm doing is the proper way and if yes, how to calculate the correct coefficient. public void createShell(Vector3 origin, Vector3 direction, Vector3 platformVelocity, float velocity) { long shellId = System.currentTimeMillis(); // hack ShellState state = getState().createShellState(shellId, origin.x, origin.y, origin.z); ShellEntity entity = EntityFactory.getInstance().createShellEntity(shellId, state); add(entity); entity.getBody().applyCentralImpulse(platformVelocity.mul(velocity * 0.02f)); // new line added, to compensate for the moving platform, no idea how to calculate proper coefficient entity.getBody().applyCentralImpulse(direction.nor().mul(velocity)); } private final Vector3 v3 = new Vector3(); public void shootGun(Vector3 direction) { Vector3 shipVelocity = world.getShipEntities().get(id).getBody().getLinearVelocity(); world.getState().getShipStates().get(id).transform.getTranslation(v3); // current location of our ship v3.add(direction.nor().mul(10.0f)); // hack; this is to avoid shell immediately impacting the ship that it got shot out from world.createShell(v3, direction, shipVelocity, 500); }

• Adding arbitrary search URLs to Firefox search bar

  - by Matthew

  New-ish versions of Firefox (I'm currently on 3.6) have the nifty "search bookmark" feature, which allows you to create searches in the location bar with custom URLs, e.g. en.wikipedia.org/wiki/%s. This is really great, but when trying to mange the engines in the search bar, I was dismayed at the lack of customisability there. It looks like the two search methods are entirely distinct. Is there a way to put custom URLs in my search bar, or do I have to just hope that whatever I want is on the long but finite list of plugins at mycroft? Thanks UPDATE: done a bit more research, posting my own answer

• The one feature that would make me invest in SSIS 2012

  - by Peter Larsson

  This week I was invited my Microsoft to give two presentations in Slovenia. My presentations went well and I had good energy and the audience was interacting with me. When I had some time over from networking and partying, I attended a few other presentations. At least the ones who where held in English. One of these was "SQL Server Integration Services 2012 - All the News, and More", given by Davide Mauri, a fellow co-worker from SolidQ. We started to talk and soon came into the details of the new things in SSIS 2012. All of the official things Davide talked about are good stuff, but for me, the best thing is one he didn't cover in his presentation. In earlier versions of SSIS than 2012, it is possible to have a stored procedure to act as a data source, as long as it doesn't have a temp table in it. In that case, you will get an error message from SSIS that "Metadata could not be found". This is still true with SSIS 2012, so the thing I am talking about is not really a SSIS feature, it's a SQL Server 2012 feature. And this is the EXECUTE WITH RESULTSETS feature! With this, you can have a stored procedure with a temp table to deliver the resultset to SSIS, if you execute the stored procedure from SSIS and add the "WITH RESULTSETS" option. If you do this, SSIS is able to take the metadata from the code you write in SSIS and not from the stored procedure! And it's very fast too. Let's say you have a stored procedure in earlier versions and when referencing that stored procedure in SSIS forced SSIS to call the stored procedure (which can take hours), to retrieve the metadata. Now, with RESULTSETS, SSIS 2012 can continue in milliseconds! This is because you provide the metadata in the RESULTSETS clause, and if the data from the stored procedure doesn't match this RESULTSETS, you will get an error anyway, so it makes sense Microsoft has provided this optimization for us.

• How can I find out which user deleted a directory?

  - by Rob S.

  My Ubuntu server has about roughly 30 active users on it. I personally know everyone using the server. Recently, a few friends and I were working on project. We made a new directory for the project and since everyone knows everyone we didn't bother protecting our work under a bunch of permissions. We should have though, because we woke up this morning to find that someone removed our entire directory. Our work is backed up every night so it's really not a big deal to restore our work. However, we would like to find out who removed it so we can confront them. So far the best thing we've come up with for finding our culprit is checking everyone's bash history but this is long and tedious and chances are that if there was a malicious intent behind the directory removal that our culprit probably modified theirs to cover their tracks (or of course they might use a different shell). So, basically, what is the easiest and quickest way to find out who deleted a directory? Thanks in advance for your time.

• Ubuntu 14.04 ATI Radeon open source driver with distorted video playback

  - by Bwog

  Video in VLC or SMplayer is often in black and white with washed-out colors in the wrong place (translated considerably). Moreover, the last video image is often visible when a new video is started and persist as long as the new video is running. Colors have a recognizable shape (e.g. a persons clothes or face), but can be obviously incorrect (e.g. green or purples faces). This is independent of the format of the videos (mp4, mkv, wmv). Sometimes all problems disappear when a new video is started, but often only a reboot restores normal video. Ubuntu was upgraded to 14.04 and is fully updated.

• How to pass a filename by drag-and-drop to a shortcut in Windows

  - by Kendall Frey

  I have a program program.exe and a document document.txt, and to open the document, I can drag document.txt onto program.exe. So far so good. Now I want to call it with a command-line parameter -param so that the full command line is program.exe -param document.txt Unfortunately, I can't do this with drag and drop, so I need to fire up cmd and type in the command manually. This takes too long, and I need an easier way. How can I create a shortcut that I can drop the file onto, and have it call the program with the command-line parameter? I tried setting the shortcut to program.exe -param "%1", but that didn't work, because it appeared to pass only the file name, and not the path, and since the current directory was the one with the program and not the one with the document, it couldn't find the document.
