• Do you do custom tests/work for a potential employer before the interview?

  - by Chuck Stephanski

  Every shop I've worked at we have followed what I thought was a standard hiring sequence: 1. solicit resumes 2. phone screen applicants we are interested in 3. in person interview 4. in some shops 2nd in person interview (just w/ CEO for example) Most places I apply to follow something along these lines. But some shops want to give me a test or ask me to build something after I send in my resume. They usually say "congratulations, you've made it to stage 2 of our hiring process!" But for all I know they are asking every applicant they get a resume from to do the same thing. This annoys me because it doesn't scale. If I'm applying for a lot of positions I can't spend all my time doing work that potentially can only land me one job. Plus there's no shared dedication to the process. If we do a 45 minute phone screen, that's 45 minutes the company commits to me and 45 minutes I commit to the company in hopes of a potential match. Do you guys have a policy regarding these sorts of things?

• What happens when you close an Adsense account?

  - by rakibtg

  I need to change my payee name, I have asked in Google Adsense product forum one of top contributor replied me: "You will have to close the account & apply again with using your real payee name. That's why they specifically state that the payee name needs to match the full name on your bank account." https://support.google.com/adsense/answer/47333?hl=en This makes sense, but got few question because the support page do not have sufficient content to help me. My questions are: What happens when you close your Adsense account? If I apply again, then what will be the process to re-gain my account? I mean should I have to apply for a website again, then Adsense team will review and approve that? Is there any chance to disapprove my account? What about current check? I have two check in my hand. So, is Google will send those check again to me with my new payee name? Anyone experienced this problem? I have asked it on Google Forum but got no answer!

• The Freemium-Premium Puzzle

  The more time I spend thinking about the value of information, the more I found that digitalizing information significantly changed the 'information markets', potentially in an irreversible manner. The graph at the bottom outlines my current view. The existing business models tend to be the same in the digital and analogue information world, i.e. revenue is derived from a combination of consumers' payments and advertisement. Even monetizing 'meta-information' such as search engines isn't new. Just think of the once popular 'Who'sWho'. What really changed is the price-value ratio. The curve is pushed down, closer to the axis. You pay less for the same, or often even get more for less. If you recall the capabilities I described in relevance of information you will see that there are many additional features available for digital content compared to analogue content. I think this is a good 'blue ocean strategy' by combining existing capabilities in a new way. (Kim W.C. & Mauborgne, R. (2005) Blue Ocean Strategies. Boston: Harvard Business School Publishing.). In addition the different channels of digital information distribution significantly change the value of information. I will touch on this in one of my next blogs. Right now, many information providers started to offer 'freemium' content through digital channels, hoping to get a premium for the 'full' content. No freemium seems to take them out of business, because they are apparently no longer visible in today's most relevant channels of information consumption. But, the more freemium is provided, the lower the premium gets; a truly puzzling situation. To make it worse, channel providers increasingly regard information as a value adding and differentiating activity. Maybe new types of exclusive, strategic alliances will solve the puzzle, introducing new types of 'gate-keepers', which - to me - somehow does not match the spirit of the WWW and the generation Y's perception of information consumption and exchange.

• Storing revisions of a document

  - by dev.e.loper

  This is a follow up question to my original question. I'm thinking of going with generating diffs and storing those diffs in the database 'History' table. I'm using diff-match-patch library to generate what is called a 'patch'. On every save, I compare previous and new version and generate this patch. The patch could be used to generate a document at specific point in time. My dilemma is how to store this data. Should I: a Insert a new database record for every patch? b. Store these patches in javascript array and store that array in history table. So there is only one db History record for document with an array of all the patches. Concerns with: a. Too many db records generated. Will be slow and CPU intensive to query. b. Only one record. If record is somehow corrupted/deleted. Entire revision history is gone. I'm looking for suggestions, concerns with either approach.

• Can I set up samba so it automatically allows all the local usernames and passwords?

  - by dialer

  I have set up samba like this (this is the complete smb.conf): [global] log file = /var/log/samba/log log level = 2 security = user [homes] browsable = false read only = no valid users = %S I'd like to enable every user on server to access their home directories, but for some unknown reason only my 'administrator' account can do so. (I have done that with ftp before, but now smb is also needed). When I try to smbclient -L localhost -U [user], I get NT_STATUS_LOGON_FAILURE, except with the administrator (which is the user created during the ubuntu installation, not root). The samba log file says NT_STATUS_NO_SUCH_USER: [2012/04/04 20:26:02.081454, 2] smbd/reply.c:554(reply_special) netbios connect: name1=LOCALHOST 0x20 name2=DIALER-X 0x0 [2012/04/04 20:26:02.081733, 2] smbd/reply.c:565(reply_special) netbios connect: local=localhost remote=dialer-x, name type = 0 [2012/04/04 20:26:02.087200, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [public] - [public] FAILED with error NT_STATUS_NO_SUCH_USER I suspect that I have to manually create samba users, but the man pages state that If the client has passed a username/password pair and that username/password pair is validated by the UNIX system's password programs, the connection is made as that username. To me that sounds like as long as the provided username/password is a valid login on the server, it should work. Am I missing something totally obvious? I don't want / can't afford to manually update the samba users and passwords to match the server's. 11.10

• Which hard disk drive is which?

  - by djeikyb

  I want to know which hard disk drive corresponds to which device path. It's trivial to match the hard disk stats (brand, size) with the dev path, but I want more. I want to know which drive is which inside my case. What's a good way to go about getting this info? Rules: I am a lazy bum. I don't want to tear apart my server to remove all the drives, then add back one by one. A reboot is acceptable. The drives are inconveniently scrunched together in the case. All label information is hidden. The case can be opened. Most disks are SATA, so theoretically hot swappable. Unplugging cables is fair game. Bonus: For a cli only solution. I'll award answer to the best/easiest gui or cli answer, and give a bounty to the next-best answer of the other kind. Or maybe the other way around, because the bounty is worth more points.

• Linux, GNU GCC, ld, version scripts and the ELF binary format -- How does it work? [closed]

  - by themoondothshine

  I'm trying to learn more about library versioning in Linux and how to put it all to work. Here's the context: I have two versions of a dynamic library which expose the same set of interfaces, say libsome1.so and libsome2.so. An application is linked against libsome1.so. This application uses libdl.so to dynamically load another module, say libmagic.so. Now libmagic.so is linked against libsome2.so. Obviously, without using linker scripts to hide symbols in libmagic.so, at run-time all calls to interfaces in libsome2.so are resolved to libsome1.so. This can be confirmed by checking the value returned by libVersion() against the value of the macro LIB_VERSION. So I try next to compile and link libmagic.so with a linker script which hides all symbols except 3 which are defined in libmagic.so and are exported by it. This works... Or at least libVersion() and LIB_VERSION values match (and it reports version 2 not 1). However, when some data structures are serialized to disk, I noticed some corruption. In the application's directory if I delete libsome1.so and create a soft link in its place to point to libsome2.so, everything works as expected and the same corruption does not happen. I can't help but think that this may be caused due to some conflict in the run-time linker's resolution of symbols. I've tried many things, like trying to link libsome2.so so that all symbols are alised to symbol@@VER_2 (which I am still confused about because the command nm -CD libsome2.so still lists symbols as symbol and not symbol@@VER_2), but nothing seems to work. What am I doing wrong?

• How can i compare Audio, what programming language should i use

  - by Pimmetje

  I have 2 audio files that are from almost the same source. But at some points there shifted a bit. Also the codecs does not match. I would like to make a program that takes a sample 2 - 4 seconds. And looks for it in the other file. (Most of the time it's not shifted more than 30 seconds). Than take the time and store it, Go ahead for a few seconds take a sample and find it again. This way i want to create a file where i can see on what points the file is shifted. For people who are more interested in what i want. I have a audio/video file speech and subtitles. But i have same speech from different sources with differs a bit in time. And i like to make a program that can correct the subtitle time for me. Enough about the problem I looked on the Internet for ways to compare audio files. Based on what i read comparing 2 audio files isn't that easy as i had hoped. Some talk about algorithms http://www.perlmonks.org/?node_id=169641 Some audio-library's portaudio.com aubio.org sourceforge.net/projects/ccaudio/ ambiera.com/irrklang/ The biggest problem i have is that i can't find something i can generate from the audio that i can use to compare with. I hope someone here can point me in the right direction.

• Allow (and correct the URL) when there is a special character such as %26 using IIS and the rewrite module

  - by plumtreematt

  I'm struggling with a legacy app that uses special characters like %26 in the URL. The characters don't affect the app but can't be changed, so I'm trying to get IIS to deal with them. I've tried to ignore them using multiple methods, but nothing seems to work. So now I installed the IIS rewrite module and added a rewrite rule to web.config to replace the characters %26 with _, for example: <rewrite> <rules> <rule name="ampersand" patternSyntax="Wildcard" stopProcessing="true"> <match url="*%26*" /> <action type="Redirect" url="{R:1}_{R:2}" /> </rule> </rules> </rewrite> The problem is that IIS responds with "Bad Request" before the rewrite rule ever gets called. So my question is this: how can I change the order of precedence so that the mod rewrite filter will be called before IIS puts the ban hammer down on that URL?

• Standard/Compliance for web programming?

  - by MarkusK

  I am working with developers right now that write code the way they want and when i tell them to do it other way they respond that its just matter of preference how to do it and they have their way and i have mine. I am not talking about the formatting of code, but rather of way site is organized in classes and the way the utilize them. and the way they create functions and process forms etc. Their coding does not match my standards, but again they argue that its matter of preference and as long as goal achieved the can be different way's to do it. I agree but their way is proven to have bugs and we spend a lot of time going back and forth with them to fix all problems security or functionality, yet they still write same code no matter how many times i asked them to stop doing certain things. Now i am ready to dismiss them but friend of mine told me that he has same exact problem with freelance developers he work with. So i don't want to trade one bad apple for another. Question is is there some world wide (or at least europe and usa) accepted standard or compliance on how write secure web based applications. What application architecture should be for maintainable application. Is there are some general standard that can be used for any language ruby php or java govern security and functionality and quality of code? Or at least for PHP and MySQL i use for my website. So i can make them follow this strict standard and stop making excuses.

• Best practice- handling images on website

  - by Steve

  I am porting an old eCommerce site to MVC 3 and would like to take advantage of design improvements. The site currently has product images stored in 3 sizes: thumbnail, medium (for display in a list) and expanded for a zoomed look. Right now we are having to upload 3 separate images that are sized exactly right, provide 3 different names that match what the site expects, etc., it is a pain. I'd like to upload just 1 file, the large one, then let the site reduce it to needed sizes, and I'd like the flexibility to change the thumbnail and list sizes depending on user preferences, form factor (e.g. mobile, iPad, desktop), etc. so might need many copies of the same image. My question is should the image be reduced then saved several times upon upload and if so what is a good storage/naming convention? The other idea is to store just the single image but resize it programmatically before serving it to the client. Has anybody done this and what are the tradeoffs besides a few more machine cycles? How do you pass a temporary image in memory to the client (there is no URL)?

• C# 2d array value check [duplicate]

  - by TLFTN

  This question already has an answer here: 3-in-a-row or more logic 4 answers I've managed to create a 2d array, then made it fill up with random numbers, like this: int[,] grid = new int[5, 5] ; Random randomNumber = new Random(); var rowLength = grid.GetLength(0); var colLength = grid.GetLength(1); for (int row = 0; row < rowLength; row++) { for (int col = 0; col < colLength; col++){ grid[row, col] = randomNumber.Next(5); Console.Write(String.Format("{0}\t", grid[row, col]));} Console.WriteLine(); } This results in an array with random values. Example: 3 0 0 3 3 1 3 3 3 2 0 0 2 0 4 3 3 2 0 3 4 0 3 3 0 Notice those three 3s which are connected to each other(in the second row), now how would I check if there's a match like this?

• Is Reading the Spec Enough?

  - by jozefg

  This question is centered around Scheme but really could be applied to any LISP or programming language in general. Background So I recently picked up Scheme again having toyed with it once or twice before. In order to solidify my understanding of the language, I found the Revised^5 Report on the Algorithmic Language Scheme and have been reading through that along with my compiler/interpreter's (Chicken Scheme) listed extensions/implementations. Additionally, in order to see this applied I have been actively seeking out Scheme code in open source projects and such and tried to read and understand it. This has been sufficient so far for me understanding the syntax of Scheme and I've completed almost all of the Ninety-nine Scheme problems (see here) as well as a decent number of Project Euler problems. Question While so far this hasn't been an issue and my solutions closely match those provided, am I missing out on a great part of Scheme? Or to phrase my question more generally, does reading the specification of a language along with well written code in that language sufficient to learn from? Or are other resources, books, lectures, videos, blogs, etc necessary for the learning process as well.

• How Does Domain Know Where Your Web Host Is Located [closed]

  - by icu222much

  Possible Duplicate: How Does Domain Know Where Your Web Host Is Located? I just purchased a domain name from RapidNames, and a hosting plan at JustHost. I was told to enter JustHost's name server (ns1.justhost.com) in my domain name's name server field and wait for 24 hours for the process to be complete. I do not understand how RapidNames can find my account on JustHost's server as I am sure I am not JustHost's only customer. I have read the article How DNS Works that John Conde has posted, but I still do not understand the issue. After reading several other articles, I am beginning to understand how it works, but I would still like someone to confirm if I am correct or not. From my understanding, linking your domain name to your web host is a two step process. First, you need to tell your domain name who your web host is. This is done by providing the two DNS server addresses. Secondly, you need to tell your web host which domain names you own by entering your domain names into the domain name manager. As a result, when someone queries your domain name, they will be forwarded to your web host. The web host will look in their database to match the domain name the account's owner, and then serve the appropriate website. I want to confirm if my understanding of how a domain knows where your web host is located is accurate?

• What kinds of languages would be most useful for this kind of webapp?

  - by Caedar

  I've had some experience with programming in the past (2-3 years of C++ self-teaching), so I'm no stranger to the programming process, but there are so many languages out there that I'm lost when thinking about this project idea that's been floating around my head: I would like to create a webapp that would be used for helping somebody figure out what kinds of productivity tools would suit them. The first part of the app would basically be a survey with a variety of questions that would help weed out tools that wouldn't be useful for them. (Slider bar between minimalist and maximizer, slider bar between all free apps and no cost limit, checkboxes on what platforms are required, etc.) While the person is filling out the survey, they will see a web of applications, webapps, and other tools forming on the screen with links showing the relationships the programs have with eachother (syncing supported, good combinations of apps, etc.), along with a list of applications below sorted by general use (notetaking, document organization, storage, etc.) I would imagine that each program entered into the database that will be accessed would have a certain set of characteristics, ie. price, user friendliness, platforms supported, general uses, etc. and the survey would be designed to correlate to those elements and remove programs that don't match the criteria set. The difficult part of this entire process would be getting the web of applications to arrange itself and render properly. Now that I've finished mind-dumping, onto my question: What kinds/combinations of programming languages would you imagine being useful for this kind of project, and why? I learn best by setting up a project for myself like this one and tinkering with the languages, so I don't mind if the end product is out of reach from my current skill level. I'd just like some guidance so I don't fumble in the dark for too long.

• Should Starting a Quick Game via Google Game Services be Iterated?

  - by user46727

  I have been following this tutorial for Google Play Game Services. I am a little unclear as to if the room matching algorithm should be looped or not. Can I just initialize this process once and let it time out? Or by iterating through it is it somehow rechecking it? If anyone had the approximate timeout that would be great as well. The problem stems from the fact that even when both phones are signing into the Game Services (at virtually the same time, my friend and I logged in), the room is not registering multiple people. One time my friend's phone even entered the game map, showing that he somehow was able to progress from the room initialization process. Relevant screen update methods which I am starting this matchmaking process: @Override public void update(float deltaTime) { game.options.updateTiles(); if(!isInitiated) { startQuickGame(); } } private void startQuickGame() { // auto-match criteria to invite one random automatch opponent. // You can also specify more opponents (up to 3). if(game.mGoogleClient.isConnected() && !isInitiated) { Bundle am = RoomConfig.createAutoMatchCriteria(1, 3, 0); // build the room config: RoomConfig.Builder roomConfigBuilder = RoomConfig.builder(Network.getInstance()); roomConfigBuilder.setMessageReceivedListener(Network.getInstance()); roomConfigBuilder.setRoomStatusUpdateListener(Network.getInstance()); roomConfigBuilder.setAutoMatchCriteria(am); RoomConfig roomConfig = roomConfigBuilder.build(); // create room: Games.RealTimeMultiplayer.create(game.mGoogleClient, roomConfig); // go to game screen this.mRoom = Network.getInstance().getRoom(); if(this.mRoom != null && this.mRoom.getParticipants().size() >= 2) { game.setScreen(new MultiGameScreen(game, this.mRoom)); isInitiated = true; } } else { game.mGoogleClient.connect(); } }

• Scaling sprite velocity / co-ordinatesin Android

  - by user22241

  I'm trying to find the answer to a question that I've had for a long time, but am having trouble finding it! I hope someone can help :-) I'm trying to find information on how to scale sprite velocity / movement / co-ordinates. What I mean by this is how do I get a sprite to move at the same speed relative to the screen size / DPI so that it takes the same amount of real-time to get from one side of the screen to the other? All of the posts pertaining to sprite scaling that I can find on the various forums relate to the size of the sprite, but this part of it I'm OK with so far, it's just that when I move a sprite, it kind of gets there at different speed depending on the dpi / resolution of the device. I hope I'm making sense. This is the code I have so far, instead of using explicit amounts, like 1, I'm using something like the following: platSpeedFloat= (1 * (dpi/160)); //Use '1' so on an MDPI screen, the sprite will move by 1 physical pixel Then basically what I'm doing is something like this: (all varialble previously declared) platSpeedSave+=platSpeedFloat; //Add the platSpeedFloat value to the current platSpeedSave value platSpeed=(int) platSpeedSave; //Cast to int so it can be checked in the following statement if (platSpeed==platSpeedSave) //Check the casted int value to float value stored previoiusly {floorY=floorY-platSpeed; //If they match then change the Y value platSpeedSave=0;} //Reset Would be grateful if someone could assists - hope I'm making sense. The above doesn't seems to work the sprite moves 'faster' on lower DPI screens. Thanks

• Is it justified to use project-wide unique function and variable names to help future refactoring?

  - by kahoon

  Refactoring tools (like ReSharper) often can't be sure whether to rename a given identifier when, for example refactoring a JavaScript function. I guess this is a consequence of JavaScript's dynamic nature. ReSharper solves this problem by offering to rename reasonable lexical matches too. The developer can opt out of renaming certain functions, if he finds that the lexical match is purely accidental. This means that the developer has to approve every instance that will be affected by the renaming. For example let's consider we have two Backbone classes which are used completely independently from each other in our application: var Header = Backbone.View.extend({ close: function() {...} }) var Dialog = Backbone.View.extend({ close: function() {...} }) If you try to rename Dialog's close method to for example closeAndNotify, then ReSharper will offer to rename all occurences of Header's close method just because they are the same lexically prior to the renaming. To avoid this problem, please consider this: var Header = Backbone.View.extend({ closeHeader: function() {...} }) var Dialog = Backbone.View.extend({ closeDialog: function() {...} }) Now you can rename closeDialog unambiguously - given that you have no other classes having a method with the same name. Is it worth it to name my functions this way to help future refactoring?

• Live HTML Preview

  - by netbeanstips

  When you need to edit an HTML document in NetBeans you may find useful this little plugin that adds a Preview tab to HTML editor window. The plugin works with some small issues in NetBeans 7.4 but I recommend using development builds instead. So install the plugin, restart NetBeans and open any HTML document. Notice there's a Preview button in editor's toolbar (see the red rectangle in the picture below). Now split the editor window by dragging the split button at top right corner. You can also use menu View - Split - Vertically.  Then in the bottom split part toggle Preview button. You will get a live preview of your HTML source code. The preview pane will auto-refresh as you edit the HTML code. There are even some handy tools in Preview toolbar, for example you can resize the preview browser to match the screen dimensions of various device types. I know there is full-blown HTML5 support in NetBeans 7.4. But if you need to edit a single document or when you're running Java-only NetBeans distribution this plugin may come handy... Note: The plugin is built on top of embedded WebKit browser which is based on JavaFX WebView component. So there might be some issue when using the plugin on some flavors of Linux.

• nhibernate mapping: A collection with cascade="all-delete-orphan" was no longer referenced

  - by Chev

  Hi All I am having some probs with my fluent mappings. I have an entity with a child collection of entities i.e Event and EventItems for example. If I set my cascade mapping of the collection to AllDeleteOrphan I get the following error when saving a new entity to the DB: NHibernate.HibernateException : A collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance: Core.Event.EventItems If I set the cascade to All it works fine? Below are my classes and mapping files: public class EventMap : ClassMap<Event> { public EventMap() { Id(x => x.Id, "Id") .UnsavedValue("00000000-0000-0000-0000-000000000000") .GeneratedBy.GuidComb(); Map(x => x.Name); HasMany(x => x.EventItems) .Inverse() .KeyColumn("EventId") .AsBag() .Cascade.AllDeleteOrphan(); } } public class EventItemMap : SubclassMap<EventItem> { public EventItemMap() { Id(x => x.Id, "Id") .UnsavedValue("00000000-0000-0000-0000-000000000000") .GeneratedBy.GuidComb(); References(x => x.Event, "EventId"); } } public class Event : EntityBase { private IList<EventItem> _EventItems; protected Event() { InitMembers(); } public Event(string name) : this() { Name = name; } private void InitMembers() { _EventItems = new List<EventItem>(); } public virtual EventItem CreateEventItem(string name) { EventItem eventItem = new EventItem(this, name); _EventItems.Add(eventItem); return eventItem; } public virtual string Name { get; private set; } public virtual IList<EventItem> EventItems { get { return _EventItems.ToList<EventItem>().AsReadOnly(); } protected set { _EventItems = value; } } } public class EventItem : EntityBase { protected EventItem() { } public EventItem(Event @event, string name):base(name) { Event = @event; } public virtual Event Event { get; private set; } } Pretty stumped here. Any tips greatly appreciated. Chev

• NHibernate mapping with optimistic-lock="version" and dynamic-update="true" is generating invalid up

  - by SteveBering

  I have an entity "Group" with an assigned ID which is added to an aggregate in order to persist it. This causes an issue because NHibernate can't tell if it is new or existing. To remedy this issue, I changed the mapping to make the Group entity use optimistic locking on a sql timestamp version column. This caused a new issue. Group has a bag of sub objects. So when NHibernate flushes a new group to the database, it first creates the Group record in the Groups table, then inserts each of the sub objects, then does an update of the Group records to update the timestamp value. However, the sql that is generated to complete the update is invalid when the mapping is both dynamic-update="true" and optimistic-lock="version". Here is the mapping: <class xmlns="urn:nhibernate-mapping-2.2" dynamic-update="true" mutable="true" optimistic-lock="version" name="Group" table="Groups"> <id name="GroupNumber" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="GroupNumber" length="5" /> <generator class="assigned" /> </id> <version generated="always" name="Timestamp" type="BinaryBlob" unsaved-value="null"> <column name="TS" not-null="false" sql-type="timestamp" /> </version> <property name="UID" update="false" type="System.Guid, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="GroupUID" unique="true" /> </property> <property name="Description" type="AnsiString"> <column name="GroupDescription" length="25" not-null="true" /> </property> <bag access="field.camelcase-underscore" cascade="all" inverse="true" lazy="true" name="Assignments" mutable="true" order-by="GroupAssignAssignment"> <key foreign-key="fk_Group_Assignments"> <column name="GroupNumber" /> </key> <one-to-many class="Assignment" /> </bag> <many-to-one class="Aggregate" name="Aggregate"> <column name="GroupParentID" not-null="true" /> </many-to-one> </class> </hibernate-mapping> When the mapping includes both the dynamic update and the optimistic lock, the sql generated is: UPDATE groups SET WHERE GroupNumber = 11111 AND TS=0x00000007877 This is obviously invalid as there are no SET statements. If I remove the dynamic update part, everything gets updated during this update statement instead. This makes the statement valid, but rather unnecessary. Has anyone seen this issue before? Am I missing something? Thanks, Steve
