• Amazon how does their remarkable search work?

  - by JonH

  We are working on a fairly large CRM system /knowledge management system in asp.net. The db is SQL server and is growing in size based on all the various relationships. Upper management keeps asking us to implement search much like amazon does. Right from there search you can specify to search certain objects like outdoor equipment, clothing, etc. and you can even select all. I keep mentioning to upper management that we need to define the various fields to search on. Their response is all fields...they probably look at the search and assume that it is so simple. I'm the guy who has to say hold on guys we are talking about amazon here. My question is how can amazon run a search on an "all" category. Also one of the things management here likes is the dynamic filters. For instance, searching robot brings up filters specific to a robot toy. How can I put management in check and at least come up with search functionality that works like amazon. We are using asp.net, SQL server 2008 and jquery.

• How do I handle mysql replication in EC2 using private IPs?

  - by chris

  I am trying to set up a mysql master/slave configuration in two EC2 instances. However, every time I reboot an instance, the IP address (and hostname) changes. I could assign an Elastic IP address, but would prefer to use the internal IP address. I can't be the first person to do this, but I can't seem to find a solution. There are a lot of "getting started" guides, but none of them mention how to handle changing IP addresses. So what are the best practices to manage master/slave replication in EC2?

• How can we achive a 403 Permissions Denied for a subdomain?

  - by marikamitsos

  We have a multisite installed in the root directory (multisite.com) and also a wordpress single installation on a subdomain (help.multisite.com) In the root .htaccess we placed: #START Security: Disallow access to folders Options All -Indexes # END Security On the main site (as expected we get) "403 Permission Denied. You do not have permission for this request /wp-content/blogs.dir/83/" Nice. :) BUT. We just noticed that when trying to access the subdomains folders we get: Internal Server Error. The server encountered an internal error or misconfiguration and was unable to complete your request.... Additionally, a 500 Internal Server Error error... This is something we do NOT want. So the question is: How can we avoid the above result and make the message for the subdomains be "403 Permission Denied" (the same as for the main site and NOT "500 Internal Server Error" (as it is now)? We put what, where?

• Reinstalled Ubuntu 12.04 and now I cannot change preferences like theme, wallpaper, and nautilus preferences

  - by krishnab

  So I just down-rev'd ubuntu from 13.04 back to 12.04 LTS desktop 64 (Precise). I am using Unity. I just reformatted the Ubuntu partition, but kept my home directory intact, and everything seemed to reconnect just fine. No data was lost. However, I found that I cannot seem to change my preferences. So I cannot seem to change my desktop background, no matter how many ways I try--Ubuntu Tweak, Gnome Tweak, system settings. I also cannot change the system GTK+ theme, though apparently I am able to change the windows border theme. Further, I cannot seem to change my Nautilus preferences--so I cannot seem the make the default view a list view, and I cannot make the "single-click" behavior the default. I even went into the nautilus org.gnome.nautilus settings to manually change things, but no luck. I thought it was a permissions issue, so I did a chown on the home folder and on the .gvfs folder. Still no luck. So somewhere there seems to be a permission that I am not catching. Does anyone have any suggestions? Thanks.

• Mysql table Crashed during Optimize, table repair taking too long

  - by hellohellosharp

  One of my vital tables was being optimzied and MySQL crashed in the middle of it. It then said the table was corrupt. I am running repair but it is taking over an hour, I need this table up ASAP (I will even truncate it if necessary). Please help me get this solved. The table has about 54 million rows.

• Multiple WAN interfaces in same subnet on Sonicwall NSA220?

  - by Ttamsen

  (eta salutation, which keeps getting eaten.) Hi, all. I see a bunch of related questions, so I'm hesitant to ask, but: I have a situation where I have a Sonicwall NSA220 serving as firewall/router for two internal subnets to two external WAN connections. In some locations this is two separate ISPs. In others, it's the same ISP but with multiple circuits. The problem is that one ISP has been unable to provide unique subnets for each WAN interface. Is there any possibility that I might be able to bond the two WAN interfaces into a single virtual interface, and then use source-routing to get internal subnets communicating out the appropriate physical interface? Or even just use traffic-shaping to give each internal network appropriate shared bandwidth? I haven't found anything in the docs, but it seemed like it might be worth asking. Thanks for any help! -Steve.

• Thinkpad CPU temperature reaches 100°C after 10 minutes of heavy use

  - by Nicolas Raoul

  Less than two years ago, I bought a Lenovo Thinkpad R500. When using the CPU heavily, it sometimes decides to reboot. I am using Linux, and a widget shows me the CPU temperature. The PC usually reboots when the temperature of the first core gets over 100°C Since I switched from Ubuntu 2010.10 32bit to Ubuntu 2011.04 64bit, it crashes much more often. I survive using these techniques: When in the office, I use a laptopcooler. When outside, I underclock to 800 MHz, by doing so it does not get too warm. QUESTION: Is it normal that a Thinkpad crashes if the CPU is at 100% for more than 10 minutes? How can I use the full power of my computer, for instance when showing CPU-hungry business intelligence tools to clients? The computer does not really feel that hot. Maybe the sensor itself is reporting wrong temperatures? Can I tell the BIOS to ignore it?

• Approaches to timed puzzle elements

  - by ndg

  I'm working on a side scrolling game that has a number of timed puzzle elements. As a simple example: I have a number of moving platforms that have been setup to transition in a pattern. Ideally I'd like to ensure that as the player first approaches them, they are in an ideal state -- whereby the player can witness the full transition and more experienced players (i.e: speedrunners) can complete the puzzle immediately without having to wait for the current transition to complete. The issue here, in a nutshell, is that because these platforms begin transitioning at the start of the level, it's impossible to correctly calculate when the player is likely to stumble upon them. I've done a fair bit of Googling but haven't managed to turn up any decent resources with regards to solving a problem like this. The obvious solution is to only begin updating the objects when the player (or more likely: the camera) first encounters them. But this becomes difficult when you consider more complicated situations. It seems like potentially the easiest way of handling this is to have an invisible trigger volume that will tell any puzzle elements located inside of it that the player has 'arrived' upon first colliding with the player. But this would mean I'd have to logically group puzzle elements, which could become fairly messy in a hurry. Take, for instance, a puzzle that appears to the right of the screen. It may take the player a number of seconds to reach it. It would look strange if the elements involved were to remain stationary. But by the time the player arrives, it's likely things will be 'out of sync'. I wanted to post here in the hopes that others know of, or have implemented, a decent solution to this problem?

• mod_usertrack with X-Forwarded-For (proxy) IPs, apache 2.2

  - by ripper234

  I'm using apache 2.2 with mod_usertrack, behind a reverse proxy (load balancer). Now, the proxy disguises the client's real IP addresses (keeps them in the X-Forwarded-For header), and forwards the request along. mod_usertrack uses the clients' IP (along with some noise) to generate a GUID for each client. However, because of the proxy, it only sees a single IP and the generated GUIDs for each client are very similar (even with some possible collisions). I would like to upgrade apache to version 2.4, but it seems to be somewhat of a project. I did manage to compile it using this post and a few others, only to discover the folder structure does not resemble the one I had before (default ubuntu). I'm weary of tweaking it myself ... and I will be making my life miserable if I want to upgrade the server later on. So ... what are my options? Is there a good unofficial repository that packages apache 2.4 for Oneiric? (please provide a short 'how to', I'm not great in installing packages) Is there an alternative route to solve this? (Upgrading just the user_track module? Another module that works with apache 2.2?)

• How to host customer developed code server side

  - by user963263

  I'm developing a multi-tenant web application, most likely using ASP.NET MVC5 and Web API. I have used business applications in the past where it was possible to upload custom DLL's or paste in custom code to a GUI to have custom functions run server side. These applications were self hosted and single-tenant though so the customer developed bits didn't impact other clients. I want to host the multi-tenant web application myself and allow customers to upload custom code that will run server side. This could be for things like custom web services that client side JavaScript could interact with, or it could be for automation steps that they want triggered server side asynchronously when a user takes a particular action. Additionally, I want to expose an API that allows customers' code to interact with data specific to the web application itself. Client code may need to be "wrapped" so that it has access to appropriate references - to our custom API and maybe to a white list of approved libraries. There are several issues to consider - security, performance (infinite loops, otherwise poorly written code, load balancing, etc.), receive compiled DLL's or require raw code, etc. Is there an established pattern for this sort of thing or a sample project anyone can point to? Or any general recommendations?

• Best practice for system clock sync on KVM host

  - by Tauren

  I have an Ubuntu 9.10 server running as a KVM host with ntpd installed on it. The host system has the correct system time. At the moment I only have a single KVM guest, also Ubuntu 9.10 server. I do not have ntpd installed on it, and I just discovered the clock is about 6 minutes slow. It wasn't that way when it was installed about a month ago. I thought that I only needed to keep the host clock synchronized and that the guests used the host clock. But maybe that is a memory from using OpenVZ. I believe the reasoning was related to only the host could modify the physical system clock. Is running ntpd on both the host and all the guests the correct thing to do? Or is there something else that is preferred? How should I keep the guest clocks in sync?

• What is your unique programming problem-solving style? [closed]

  - by gcc

  Everyone has their own styles and technique for approaching and solving real world problems. These distinguish us from other people or other programmers. (Actually, I think it make us more desirable as programmers and improves computer science) To improve, we read a lot of books; for example, programming style, how to solve problems, how to approach problems, software and algorithms, et al. Can I learn your technique? In other words, if someone gives you a problem, at first step, what are you doing to solve it? I want learn the style in which you approach, analyze, and solve a problem. EDIT: every programmer is a unique instance; each of us approach problems and converge on solutions in our own... idiomatic manner. This manner is sometimes a quirk of training, a bias of tools, but often it is an insightful nugget, a little golden hammer that cracks nuts just slightly faster then others. When answering, give your general approaches but also take a moment to identify how you look at things in ways that your peers do not. Let's call this your Unique Solving Perspective, or USP.

• Does it matter the direction of a Huffman's tree child node?

  - by Omega

  So, I'm on my quest about creating a Java implementation of Huffman's algorithm for compressing/decompressing files (as you might know, ever since Why create a Huffman tree per character instead of a Node?) for a school assignment. I now have a better understanding of how is this thing supposed to work. Wikipedia has a great-looking algorithm here that seemed to make my life way easier. Taken from http://en.wikipedia.org/wiki/Huffman_coding: Create a leaf node for each symbol and add it to the priority queue. While there is more than one node in the queue: Remove the two nodes of highest priority (lowest probability) from the queue Create a new internal node with these two nodes as children and with probability equal to the sum of the two nodes' probabilities. Add the new node to the queue. The remaining node is the root node and the tree is complete. It looks simple and great. However, it left me wondering: when I "merge" two nodes (make them children of a new internal node), does it even matter what direction (left or right) will each node be afterwards? I still don't fully understand Huffman coding, and I'm not very sure if there is a criteria used to tell whether a node should go to the right or to the left. I assumed that, perhaps the highest-frequency node would go to the right, but I've seen some Huffman trees in the web that don't seem to follow such criteria. For instance, Wikipedia's example image http://upload.wikimedia.org/wikipedia/commons/thumb/8/82/Huffman_tree_2.svg/625px-Huffman_tree_2.svg.png seems to put the highest ones to the right. But other images like this one http://thalia.spec.gmu.edu/~pparis/classes/notes_101/img25.gif has them all to the left. However, they're never mixed up in the same image (some to the right and others to the left). So, does it matter? Why?

• Mac OS X: pushing all traffic through a VMWare VM [closed]

  - by bj99

  I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

• Is this a bug in Profiler or Entity Framework?

  - by AjarnMark

  Using Entity Framework 4 with stored procedures and SQL Server 2008 SP1... When running SQL Server Profiler (TSQL_SPs template), the lines that show my stored procedure call and its statements say that they executed in DatabaseID = 1 (Master) but it is actually happening in my application database (ID = 8). The procedures execute properly and return the data, and they only exist in my application database, so why does Profiler mark those lines as being in Master? Is this a bug in Profiler? Is it a bug in EF4? Note that running the same code against a SQL 2000 instance, Profiler correctly shows the application's database ID.

• How to Handle frame rates and synchronizing screen repaints

  - by David Kroukamp

  I would first off say sorry if the title is worded incorrectly. Okay now let me give the scenario I'm creating a 2 player fighting game, An average battle will include a Map (moving/still) and 2 characters (which are rendered by redrawing a varying amount of sprites one after the other). Now at the moment I have a single game loop limiting me to a set number of frames per second (using Java): Timer timer = new Timer(0, new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { long beginTime; //The time when the cycle begun long timeDiff; //The time it took for the cycle to execute int sleepTime; //ms to sleep (< 0 if we're behind) int fps = 1000 / 40; beginTime = System.nanoTime() / 1000000; //execute loop to update check collisions and draw gameLoop(); //Calculate how long did the cycle take timeDiff = System.nanoTime() / 1000000 - beginTime; //Calculate sleep time sleepTime = fps - (int) (timeDiff); if (sleepTime > 0) {//If sleepTime > 0 we're OK ((Timer)e.getSource()).setDelay(sleepTime); } } }); timer.start(); in gameLoop() characters are drawn to the screen ( a character holds an array of images which consists of their current sprites) every gameLoop() call will change the characters current sprite to the next and loop if the end is reached. But as you can imagine if a sprite is only 3 images in length than calling gameLoop() 40 times will cause the characters movement to be drawn 40/3=13 times. This causes a few minor anomilies in the sprited for some charcters So my question is how would I go about delivering a set amount of frames per second in when I have 2 characters on screen with varying amount of sprites?

• Simple copy to pen-drive - 0x80070057

  Hello guys, I have this problem for a while and still didn't find the answer. I'm copying a specifc 10mb file to my pen-drive, from any folder on PC to any folder on the pen-drive and all i get is this: 0x80070057 The parameter is incorrect I simply cannot copy the file at all!! The pen-drive in case is my Nokia 5800, in "Mass Storage" mode. Sometimes I cannot copy a single MP3 file, 5 or 7mb. So i have to disconnect and connect again. The source file is not corrupted, the destination works fine with other files. It's just with some files. If I change to another pen-drive, works fine.

• Is this kind of design - a class for Operations On Object - correct?

  - by Mithir

  In our system we have many complex operations which involve many validations and DB activities. One of the main Business functionality could have been designed better. In short, there were no separation of layers, and the code would only work from the scenario in which it was first designed at, and now there were more scenarios (like requests from an API or from other devices) So I had to redesign. I found myself moving all the DB code to objects which acts like Business to DB objects, and I've put all the business logic in an Operator kind of a class, which I've implemented like this: First, I created an object which will hold all the information needed for the operation let's call it InformationObject. Then I created an OperatorObject which will take the InformationObject as a parameter and act on it. The OperatorObject should activate different objects and validate or check for existence or any scenario in which the business logic is compromised and then make the operation according to the information on the InformationObject. So my question is - Is this kind of implementation correct? PS, this Operator only works on a single Business-wise Operation.

• SQL SERVER – Finding Size of a Columnstore Index Using DMVs

  - by pinaldave

  Columnstore Index is one of my favorite enhancement in SQL Server 2012. A columnstore index stores each column in a separate set of disk pages, rather than storing multiple rows per page as data traditionally has been stored. In case of the row store indexes multiple pages will contain multiple rows of the columns spanning across multiple pages. Whereas in case of column store indexes multiple pages will contain (multiple) single columns.  Columnstore Indexes are compressed by default and occupies much lesser space than regular row store index by default. One of the very common question I often see is need of the list of columnstore index along with their size and corresponding table name. I quickly re-wrote a script using DMVs sys.indexes and sys.dm_db_partition_stats. This script gives the size of the columnstore index on disk only. I am sure there will be advanced script to retrieve details related to components associated with the columnstore index. However, I believe following script is sufficient to start getting an idea of columnstore index size.  SELECT OBJECT_SCHEMA_NAME(i.OBJECT_ID) SchemaName, OBJECT_NAME(i.OBJECT_ID ) TableName, i.name IndexName, SUM(s.used_page_count) / 128.0 IndexSizeinMB FROM sys.indexes AS i INNER JOIN sys.dm_db_partition_stats AS S ON i.OBJECT_ID = S.OBJECT_ID AND I.index_id = S.index_id WHERE  i.type_desc = 'NONCLUSTERED COLUMNSTORE' GROUP BY i.OBJECT_ID, i.name Here is my introductory article written on SQL Server Fundamentals of Columnstore Index. Create a sample columnstore index based on the script described in the earlier article. It will give the following results. Please feel free to suggest improvement to script so I can further modify it to accommodate enhancements.

• Since a few days, Dropbox stopped syncing

  - by Fabio

  Theres a new problem with nautilus-dropbox and is the worst for a service like Dropbox: stopped syncing and their tech support don't believe their users. The problem is: start dropbox it downloads index creates folders start to download files stop downloading files or the speed is like 0.3k/seg even deleting everything doesn't work, even syncing a single folder with a few files, not even configuring a different limit speed or let all your bandwith, nothing works for me and i have found many users with the same problem. it's strange, i have two computers with ubuntu 14.04 and one with windows 7, and in one of the linux machines it works fine, but not in the other one. Both of them are x64. The answers from the tech support starts with "delete everything and reinstall" to "you may be blocking port 443", yeah, sure (and if i do that half of internet dissapears, idiot), but nothing works. Someone has some idea? i cant find any log file (at least a text log file like in /var/log) to understand what is dropbox doing and what is not working. PS: sorry for my "english", is not my language Examples: dropbox slow on ubuntu 14.04 Dropbox does not sync on ubuntu 14.04 Dropbox Status (in spanish but is the same thing) fabio@canopus:~$ dropbox status Sincronizando (Quedan 330 archivos., Faltan 9 días.)

• How could I represent 1.625 by 0 or a 1 (binary digit)?

  - by pepito

  This is an excerpt from wikipedia about 'full rate' speech coding standard. Full Rate or FR or GSM-FR or GSM 06.10 was the first digital speech coding standard used in the GSM digital mobile phone system. The bit rate of the codec is 13 kbit/s, or 1.625 bits/audio sample. And this one is an excerpt from wikipedia about bit. In computing parlance, bit is the abbreviation for a single binary digit, represented by a 0 or a 1. How could I represent 1.625 by 0 or a 1? Actually, that's my lecturer's question that I could not answer. Some links to papers are more than welcome. Thanks in advance.
