  • Programming and Ubiquitous Language (DDD) in a non-English domain

    - by Sandor Drieënhuizen
    I know there are some questions already here that are closely related to this subject but none of them take Ubquitous Language as the starting point so I think that justifies this question. For those who don't know: Ubiquitous Language is the concept of defining a (both spoken and written) language that is equally used across developers and domain experts to avoid inconsistencies and miscommunication due to translation problems and misunderstanding. You will see the same terminology show up in code, conversations between any team member, functional specs and whatnot. So, what I was wondering about is how to deal with Ubiquitous Language in non-English domains. Personally, I strongly favor writing programming code in English completely, including comments but ofcourse excluding constants and resources. However, in a non-English domain, I'm forced to make a decision either to: Write code reflecting the Ubiquitous Language in the natural language of the domain. Translate the Ubiquitous Language to English and stop communicating in the natural language of the domain. Define a table that defines how the Ubiquitous Language translates to English. Here are some of my thoughts based on these options: 1) I have a strong aversion against mixed-language code, that is coding using type/member/variable names etc. that are non-English. Most programming languages 'breathe' English to a large extent and most of the technical literature, design pattern names etc. are in English as well. Therefore, in most cases there's just no way of writing code entirely in a non-English language so you end up with a mixed languages. 2) This will force the domain experts to start thinking and talking in the English equivalent of the UL, something that will probably not come naturally to them and therefore hinders communication significantly. 3) In this case, the developers communicate with the domain experts in their native language while the developers communicate with each other in English and most importantly, they write code using the English translation of the UL. I'm sure I don't want to go for the first option and I think option 3 is much better than option 2. What do you think? Am I missing other options?

  • OpenGL: Want to keep gun on top of car and be able to control angle. Having difficulties.

    - by Blair
    So I am making a simple game. I want to put a gun on top of a car so basically like a long rod in the middle of a black is how I am modelling it right now. I want to be able to control the angle of the gun. Basically it can go forward all the way so that it is parallel to the ground facing the direction the car is moving or it can point behind the car and any of the angles in between these positions. I have something like the following right now but its not really working. Is there an better way to do this that I am not seeing? #This will place the car glPushMatrix() glTranslatef(self.position.x,1.5,self.position.z) glRotated(self.rotation, 0.0, 1.0, 0.0) glScaled(0.5, 0.5, 0.5) glCallList(self.model.gl_list) glPopMatrix() #This will place the gun on top glPushMatrix() glTranslatef(self.position.x,2.5,self.position.z) glRotated(self.tube_angle, self.direction.z, 0.0, self.direction.x) print self.direction.z glRotated(45, self.position.z, 0.0, self.position.x) glScaled(1.0, 0.5, 1.0) glCallList(self.tube.gl_list) glPopMatrix() This almost works. It moves the gun up and down. But when the car moves around the angle of the gun changes. Not what I want.

  • Load balancing two web servers with ultra monkey

    - by Mark L
    Hello, In 2006 a company I was working with setup two load balancers to balance traffic between two web servers. We used ultra monkey to do so. I'm hoping to do the same now. My question: Would anyone recommend using ultra monkey to balance traffic between two linux boxes running apache? Are there other linux-based alternatives which have since proven to be better for this task? Would you still install debian sarge on a load balancer given it's age? Thanks everyone!

  • How to copy partition from one disc to another (boot partition keeping all the vital data)?

    - by Patryk
    I have bought a new laptop but the HDD, which runs at 5400 rpm, is not sufficient for me. The laptop runs Windows 7 64-bit. I have my 'old' one (a better one - Seagate Momentus 7200 rpm) and I would like to replace it but without reinstalling everything. And there my question arises: can I copy my boot partition from my laptop hard drive to my old drive so that it will boot from it properly? If so, then how to do it? Will Norton Ghost be useful here? My point would be to just replace this partition and leave the rest.

  • Does anyone use the L-Track trackball?

    - by thethinman
    I've been using the Logitech Trackman Marble Mouse for years. Now I'm looking for a trackball with a scroll wheel, larger and heavier ball, and preferably rollers instead of pins. It must be finger (not thumb) operated. The Kensington Expert Mouse is close, but from what I've read the scroll wheel is poorly implemented. They also switched from rollers to pins. I bought a Kensington Orbit Trackball and it's not bad but the scroll wheel is rough and the ball is the same as the marble mouse. I'm still looking for something better. I found the L-Trac and it looks good but there's little info on the web. Has anyone used it and can provide their impressions? Or can you point out another option?

  • What is a 'best practice' backup plan for a website?

    - by HollerTrain
    I have a website which is very large and has a large user-base. I am trying to think of a 'best practice' way to create a back up or mirror website, so if something happens on domain.com, I can quickly point the site to backup.domain.com via 401 redirect. This would give me time to troubleshoot domain.com while everyone is viewing backup.domain.com and not knowing the difference. Is my method the ideal method, or have you enacted better methods to creating a backup site? I don't want to have the site go down and then get yelled at every minute while I'm trying to fix it. Ideally I would just 'flip the switch' and it would redirect the user to a backup. Any insight would be greatly appreciated.

  • Using json as database with EF, how can I link EF and the json file during DbContext initialization?

    - by blacai
    For a personal testing-project I am considering to create a SPA with the following technologies: ASP.NET MVC + EF + WebAPI + AngularJS. The project will make use of small amount of data, so I was thinking I could use just a .json file as storage. But I am not sure about how to proceed with the link between EF and the json file in the initialization of the DbContext. I found a stackoverflow related question: http://stackoverflow.com/questions/13899342/can-we-use-json-as-a-database I know the basics of edit files and store data inside. What I tried is to get the data from the json file in the initilizer method and create the objects one by one. This is more a doubt about how this works if I save/update an object in the dbcontext, do I need to go through all the elements and add/update it manually? Is it better to rewrite the complete file? According to this http://stackoverflow.com/questions/7895335/append-data-to-a-json-file-with-php it is not a good practice to use json/XML for data wich will be manipulated. Anyone has experience with anything similar? Is this a really bad idea and I should use another kind of data-storage?

  • Data Aggregation of CSV files java

    - by royB
    I have k csv files (5 csv files for example), each file has m fields which produce a key and n values. I need to produce a single csv file with aggregated data. I'm looking for the most efficient solution for this problem, speed mainly. I don't think by the way that we will have memory issues. Also I would like to know if hashing is really a good solution because we will have to use 64 bit hashing solution to reduce the chance for a collision to less than 1% (we are having around 30000000 rows per aggregation). For example file 1: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,50,60,70,80 a3,b2,c4,60,60,80,90 file 2: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,30,50,90,40 a3,b2,c4,30,70,50,90 result: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,80,110,160,120 a3,b2,c4,90,130,130,180 algorithm that we thought until now: hashing (using concurentHashTable) merge sorting the files DB: using mysql or hadoop or redis. The solution needs to be able to handle Huge amount of data (each file more than two million rows) a better example: file 1 country,city,peopleNum england,london,1000000 england,coventry,500000 file 2: country,city,peopleNum england,london,500000 england,coventry,500000 england,manchester,500000 merged file: country,city,peopleNum england,london,1500000 england,coventry,1000000 england,manchester,500000 The key is: country,city. This is just an example, my real key is of size 6 and the data columns are of size 8 - total of 14 columns. We would like that the solution will be the fastest in regard of data processing.

  • Why is the size of antivirus greater than that of anti malware? [on hold]

    - by Mistu4u
    Recently my computer was attacked by different kinds of worms and my computer was slowed down. So I tried to remove them by installing Avast free antivirus. The worms were copying themselves rapidly. But after installing avast, I observed it only blocked new copy of the worms to be created but could not delete the already created worms, even it could not find worms in a good amount. Then I downloaded Malwarewbyte Anti Malware and to my surprise I found out its service was way too better than Avast antivirus. It detected and deleted almost 2065 worms and malwares from my computer and now my computer is doing fine. As far as I know, anti malware functionality is also included in Antivirus, But then also its performance is poor. Now my question is if performance of antiviruses are meat to be poor than Antimalwares, then why the size of Avast is 179Mb and the size of Malwarebyte is 9.81mb?

  • How to use the Nautilus search option

    - by Luis Alvarado
    In Nautilus if I press CTRL+F I get a search box that helps me search in the current directory and sub directories for specific names, but what if I want to: Find ALL files (including files without extensions) Find a file without an extension (Without the dot symbol or without any other name/extension separator) Find a file with/without a special character Find all files that start/not start with a character Find all files that end/not end with a character Find all files that start/no start with a character but end/not end with a character Find only files/folders Find files with specific text in them Find files with less/more/equal than/to X size Find files modified/created in X date All of this searches in the Nautilus search box I mentioned before. I ask this since the KDE's search is much better in this and gives pretty good freedom in searching for virtually anything, so I might not be learning how to use the Nautilus search option correctly. Note that I am talking about the first search done since some of this options show AFTER a search is done so the user can narrow it down more by doing a more specific search inside the Search results (for the first search). I am asking here how to do any of the search options I mentioned above in the first search.

  • Freeware Local Proxy for Proxy Chaining with HTTPAUTH

    - by pepoluan
    I am looking for a freeware local proxy to perform proxy-chaining with HTTPAUTH. To explain my situation: In my workplace I am forced to keep switching between several internet-connected apps, and thus everytime I have to type in the credentials (or, at least, click on 'OK' to send my previously-saved credential). To make matters more annoying, the proxy login times out every 30 minutes, requiring me to lather-rinse-repeat the whole annoyance. I'd like to just point them all to a locally installed proxy which will on its own perform the required HTTPAUTH against the corporate proxy. I've tried Cntlm, but it always fail to authenticate (and according to this thread, that is due to the proxy using HTTPAUTH which is not supported by Cntlm) Any suggestions? ETA: I found Polipo, but it's kinda wonky on Windows. Especially if I visit a new URL, and the DNS server is a bit slow, then Polipo will simply drop/refuse the connection. And I have to put my password in plaintext. If there's a better suggestion, I'm all ears.

  • Demystifying "chunked level of detail"

    - by Caius Eugene
    Just recently trying to make sense of implementing a chunked level of detail system in Unity. I'm going to be generating four mesh planes, each with a height map but I guess that isn't too important at the moment. I have a lot of questions after reading up about this technique, I hope this isn't too much to ask all in one go, but I would be extremely grateful for someone to help me make sense of this technique. 1 : I can't understand at which point down the Chunked LOD pipeline that the mesh gets split into chunks. Is this during the initial mesh generation, or is there a separate algorithm which does this. 2 : I understand that a Quadtree data structure is used to store the Chunked LOD data, I think i'm missing the point a bit, but Is the quadtree storing vertex and triangles data for each subdivision level? 3a : How is the camera distance usually calculated. When reading up about quadtree's, Axis-aligned bounding box's are mentioned a lot. In this case would each chunk have a collision bounding box to detect the camera or player is nearby? or is there a better way of doing this? (raycast maybe?) 3b : Do the chunks calculate the camera distance themselves? 4 : Does each chunk have the same "resolution". for example at top level the mesh will be 32x32, will each subdivided node also be 32x32. Example below:

  • Performance issues with visibility detection and object transparency

    - by maul
    I'm working on a 3d game that has a view similar to classic isometric games (diablo, etc.). One of the things I'm trying to implement is the effect of turning walls transparent when the player walks behind them. By itself this is not a huge issue, but I'm having trouble determining which walls should be transparent exactly. I can't use a circle or square mask. There are a lot of cases where the wall piece at the same (relative) position has different visibility depending on the surrounding area. With the help of a friend I came up with this algorithm: Create a grid around the player that contains a lot of "visibility points" (my game is semi tile-based so I create one point for every tile on the grid) - the size of the square's side is close to the radius where I make objects transparent. I found 6x6 to be a good value, so that's 36 visibility points total. For every visibility point on the grid, check if that point is in the player's line of sight. For every visibility point that is in the LOS, cast a ray from the camera to that point and mark all objects the ray hits as transparent. This algorithm works - not perfectly, but only requires some tuning - however this is very slow. As you can see, it requries 36 ray casts minimum, but most of the time 60-70 depending on the position. That's simply too much for the CPU. Is there a better way to do this? I'm using Unity 3D but I'm not looking for an engine-specific solution.

  • Can .htaccess slow down a site?

    - by Cody Sharp
    I'm working with a client on an e-commerce website. I implemented clean URLs using .htaccess. I also used .htaccess to solve canonical issues such as redirecting www to non-www and removing index.php from the URL. The website recently began to slow down dramatically, sometimes not even loading. The site is hosted on GoDaddy, and when the client called GoDaddy they told him it was the .htaccess file slowing down the website. I find this highly unlikely because of my past experiences, but I'm not 100% sure. My thinking is that the client's website is most likely on a shared server with a busy neighborhood, thus slowing down the site. It's not always slow, but rather sporadic throughout the day, loading fast at some points and slow at other points in time. Can the .htaccess file slow down a website to a crawl? If so, are there better ways to solve these problems with different rewrite rules and such? Here is what the actual .htaccess file looks like: Options +FollowSymlinks RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} ^www.example.net [NC] RewriteRule ^(.*)$ http://example.net/$1 [L,R=301] RewriteRule ^products/([0-9a-zA-Z\_\-]*)\.htm([l]?)$ index.php p=product&product_code=$1 [L] RewriteRule ^catalog/([0-9a-zA-Z\_\-]*)\.htm([l]?)$ index.php p=catalog&catalog_code=$1 [L] RewriteRule ^pages/([0-9a-zA-Z\_\-]*)\.htm([l]?)$ index.php?p=page&page_id=$1 [L] RewriteRule ^index\.htm([l]?)$ index.php?p=home [L] RewriteRule ^site_map\.htm([l]?)$ index.php?p=site_map [L] RewriteCond %{QUERY_STRING} ^p=home$ RewriteRule (.*) ? [R=permanent] I'm a .htaccess and regex novice, so any pointed out mistakes would also help. Thank you.

  • Using LDAP Attributes to improve performance for large directories

    - by Vineet Bhatia
    We have a LDAP directory with more than 50,000 users in it. LDAP Vendor suggests maximum limit of 40,000 users per LDAP group. We have number of inactive users and those are being purged but what if we don't get below the 40,000 users? Would switching to using multivalued attribute at user record level instead of using LDAP groups yield better performance during authentication, adding new users, etc? I know most server software (portal, application servers, etc) use LDAP groups. But, we have a standardized web service interface for access control instead of relying on server software to map LDAP groups to security roles. Each application uses this common "access control web service". Security roles are used within application to build fine-grained ACL used within each enterprise application.

  • Programmer + Drugs =? [closed]

    - by sytycs
    I just read this quote from Steve Jobs: "Doing LSD was one of the two or three most important things I have done in my life." Now I'm wondering: Has there ever been a study where programmers have been given drugs to see if they could produce "better" code? Is there a programming concept, which originated from people who where drug-users? Do you know of a piece of code, which was written by someone under the influence? EDIT So I did a little more research and it turns out Dennis R. Wier actually documented how he took LSD to wrap his head around a coding project: "At one point in the project I could not get an overall viewpoint for the operation of the entire system. It really was too much for my brain to keep all the subtle aspects and processing nuances clear so I could get a processing and design overview. After struggling with this problem for a few weeks, I decided to use a little acid to see if it would enable a breakthrough, because otherwise, I would not be able to complete the project and be certain of a consistent overall design"[1] There is also an interesting article on wired about Kevin Herbet, who used LSD to solve tough technical problems and chemist Kary Mullis even said "...that LSD had helped him develop the polymerase chain reaction that helps amplify specific DNA sequences."

  • A good tool for browser automation/client-side Web scripting

    - by hardmath
    I'm interested in adopting a tool/scripting language to automate some daily tasks connected with fighting forum spammers. A brief overview of these tasks: analyze new registrations and posts on a phpBB forum, and delete or deactivate spammers using a website/community that collects such spam reports. Typically such automation is integrated into the phpBB installation itself, which certainly has its advantages. My approach has the advantage of independent operation, etc. One way to think about this is in terms of browser automation. I've used iOpus iMacros for Firefox (the free version) in the past to respond to individual spammers, but current attacks are highly distributed. My "logic" for pigeonholing spammers vs. nonspammers seems beyond the easy reach of the free version of iMacros. From a more technical perspective one can think about dispensing with the browser altogether and programming GET/POST requests directed to my forum and other Web-based resources. I'm familiar with some scripting languages like Ruby and Lua, but I could be persuaded that a compiled application is better suited for these tasks. However in my experience the dynamic flexibility of interpreted environments is very useful in prototyping and debugging the application logic. So I'm leaning in the direction of scripting languages. Among browsers I favor Firefox and Chrome. I use both Windows and Linux platforms, and if the tool can adapt to an Android platform, it would make a neat demonstration of skills, yes? Thanks in advance for your suggestions!

  • Unit Tests as a learning tool - a good idea?

    - by Ekkehard.Horner
    I'm interested in ways and means for learning (a) programming language(s) efficiently. I believe that using Unit Test concepts and infrastructure early in that process is a good thing, even better than starting with "Hello world". Why: To write a decent program even for a toy/restricted problem in a new language, you'll have to master many heterogenous concepts (control flow & variables & IO ...), you are tempted to glance over details just to get your program 'to work'. Putting (your understanding of) the facts about the new language in assertions with good descriptions (=success messages) enforces thinking thru/clearness/precision. Grouping topics and adding assertions to such groups is much easier than incorporation features from the 2. chapter of your "Learning X" book to your chapter 1 program. Why not: 'Real' Unit Tests are meant to output "1234 tests ok; 1 failure: saveWorld() chokes on negative input"; 'didactic' Unit Tests should output relevant facts about the new language like perl6 10-string.t # ### p5chop ... ok 13 - p5chop( "cbä" ) returns "ä" ok 14 - after that, victim is changed to "cb" # ### (p6) chop ... ok 27 - (p6) chop( "cbä" ) returns chopped copy: "cb" ok 18 - after that, victim is unchanged: "cbä" # ### chomp ... So (mis?)using Unit Tests may be counterproductive - practicing actions while learning you wouldn't use professionally. How: Writing 'didactic' Unit Tests in languages with lightweight testing systems (Perl 5/6) is easy; (mis?)using more elaborate systems (JUnit, CppUnit) may be not worth the effort or not suitable for a person just starting with a new language. So Is using Unit Tests as a learning tool a bad idea? Can the Unit Test tool(s) of your favourite language(s) used didactically?
