• Does NASA license the software that it develops?

  - by Abe

  NASA provides a visualization software called Panoply. There is a Credits and Acknowledgments page that acknowledges and lists the licenses of software dependencies, but provides no information about its own license. I have looked at other software produced by NASA, including the source code for GISS and can not find any information about a licence. The closest information that I can find is in the FAQ for the global climate model EdGCM Global that says the code is in the "public domain" is it standard practice at NASA to release code into the public domain? are there exceptions? Can I assume that Panoply is public domain and can be used without restriction other than than those imposed by licenses of software dependencies? Is the absence of specific permission to reuse the code a concern (this issue was raised in the answer to a separate question) How common is this practice across government agencies?

• What options are there for integrating with payment gateways? [closed]

  - by Rowland Shaw

  It seems that there are only two types of payment gateway service out there at the moment; Either that the entire cart logic is handled offsite (with something like Paypal's Standard option) or the other option being that you need to go through the certification for handling credit card numbers and doing pretty much everything yourself. Ideally, for the project I'm working on, I'm after a bit of middle ground such that I can handle the cart on-site, and only pass over to a payment gateway (with an order amount, billing & delivery details, and order ref) for them to handle the card details, before passing back. I'm sure that I've used e-commerce sites using this pattern before, but I cannot find any payment providers out there that offer this sort of option, so are there any? The only over requirement we have at present is that it must accept orders in Sterling.

• Adsense link units trageting better keywords?

  - by user1010609

  I have one link unit above my navigation which targets exact keywords on what my site is about, on contrary my adsense for content Leadbord and Wide Skyscraper show ads that are totally opposite from my keyword,while my ctr increased for about 10 times with link unit I noticed cpc is lower also (but that was just based on one day, today is higher). Is it so bad to completly get rid of standard content ads and put link units, because this way I earn so little for that site but I think that is because smart pricing (accidental clicks on ads that my users are not interested)? I earn in whole day with about 25-35 clicks as much as keyword tool shows for only one click,my site is first for the topic? I really don't know what to do.. Has anyone had similar situation or can give some advice?

• Swiffy le convertisseur de fichiers Flash en HTML5 de Google

  Swiffy le convertisseur de fichiers Flash en HTML5 De Google Google vient de lancer un nouveau service permettant de convertir en quelques clics les fichiers Falsh (.fla) en fichiers HTML5. L'outil a été développé à l'origine par Pieter Senster, un ingénieur qui avait effectué un stage l'été dernier à Mountain View. Ses travaux portaient sur la manière d'afficher des animations Flash sur des appareils ne supportant pas la technologie d'Adobe comme l'iPhone ou l'iPad. Le résultat de ses recherches a donné naissance à "Swiffy", un service qui s'appuie sur le support de la technologie SVG par les navigateurs, couplé au standard du CSS3 et au format d'échange de données JSON....

• Testing To Prevent Cascading Bugs

  - by jfrankcarr

  Yesterday, Twitter was hit with a "Cascading Bug" as described in this blog post: A “cascading bug” is a bug with an effect that isn’t confined to a particular software element, but rather its effect “cascades” into other elements as well. I've seen this kind of bug, on a smaller scale of course, on some projects I've worked on. They can be difficult to identify in dev/test environments, even within a test driven development environment. My questions are... What are some strategies you use, beyond the basic TDD and standard regression testing, to identify and prevent the potential trouble points that might only occur in the production environment? Does the presence of such problems indicate a breakdown in the software development process or simply a by-product of complex software systems?

• How to discriminate vertical from horizontal scroll on Kubuntu/KDE mouse action for switch Desktop

  - by sandroid

  Currently trying out KDE, and I'm a big user of multiple workspaces/desktops while I work. I've noticed that essentially, KDE isn't able (or doesn't bother?) to tell between my mouse's standard vertical scroll, and the left/right scroll that it has. Just FYI, my mouse has a pretty sensitive scroll wheel with no discernible "clicks" so I can easily make my desktop look like it's on crack. Here's what I'd like: vertical scroll does nothing when applied on desktop, but left/right scroll causes me to switch to previous/next desktop. Here's what happens now - per settings for Desktop Settings -- Mouse Actions: Whether I scroll up/down or if I click left/right, I switch desktops. Thanks for your help

• Why isn't LISP more widespread?

  - by Andrea

  I am starting to learn Scheme by the SICP videos, and I would like to move to Common Lisp next. The language seems very interesting, and most of the people writings books on it advocate that it has unequalled expressive power. CL seems to have a decent standard library. Why is not Lisp more widespread? If it is really that powerful, people should be using it all over, but instead it is nearly impossible to find, say, Lisp job advertisements. I hope it is not just the parenthesis, as they are not a great problem after a little while.

• Should a primary key be immutable?

  - by Vincent Malgrat

  A recent question on stackoverflow provoked a discussion about the immutability of primary keys. I had thought that it was a kind of rule that primary keys should be immutable. If there is a chance that some day a primary key would be updated, I thought you should use a surrogate key. However it is not in the SQL standard and some RDBMS' "cascade update" feature allows a primary key to change. So my question is: is it still a bad practice to have a primary key that may change ? What are the cons, if any, of having a mutable primary key ?

• What do you call the process of converting line breaks into html elements?

  - by Ben Lee

  On sites with user-created content (such as programmers SE) or blogging software back-ends, line breaks entered by the user in the content area are frequently converted into <br> and/or <p> tags when rendered on the front-end. For example, this: A limerick There once was a man from Nantucket Who kept all his cash in a bucket. Might render html like this: <p> A limerick </p> <p> There once was a man from Nantucket<br> Who kept all his cash in a bucket. </p> What is the standard name for this process of converting line breaks into html?

• Not Quite Multiseat

  - by user2773520

  I am attempting to create a pair programming environment sort of set up like multiseat: https://help.ubuntu.com/community/MultiseatX[1] or https://help.ubuntu.com/community/MultiseatOneCard[2] (as the standard issue boxes only have one graphics card) The thing is, I only want one login session, just with 2 monitors, keyboards, and mice. As well as having 2 active applications (so 2 people can be typing independantly). They should ideally be able to mouse over and click & type in the other persons monitor, as well as move windows between the montors. Does anybody know of anything like this that will work? We are running Ubuntu 12.04.

• Hover alternatve for touch devices [migrated]

  - by Joshua Frank

  I'm building a standard infographic where you mouse over a region and the image changes as you move. For instance, imagine a map of the world, and when you mouse over a country, that country glows and a panel shows statistics about that country. The implementation is to have a separate image for the glowing country, and a div element with the statistics, and the code shows these additional elements on a hover over the country. The question is: what should this do on a tablet, where there's no hover event? What's a good alternative navigation metaphor for this kind of situation on touch-only devices?

• RPG Item processing

  - by f00b4r

  I started working on an item system for my (first) game, and I'm having a problem conceptualizing how it should work. Since Items can produce a bunch of potentially non-standard actions (revive a character vs increasing some stat) or have use restrictions (can only revive if a character is dead). For obvious reasons, I don't want to create a new Item class for every item type. What is the best way to handle this? Should I make a handful of item types (field modifiers, status modifiers, )? Is it normal to script item usage? Could (should?) this be combined with the above mentioned solution (have a couple of different sub item types, make special case items usage scripted)? Thanks.

• Boot Failure: No default or UI configuration directive found Normal install on laptop [closed]

  - by user79920

  I have had Ubuntu on my laptop for quite a while, it's just a standard install, no partitioning off, no wierdness of any other sort, just ubuntu. Today my computer started to lag really bad so I tried to restart it, but after bios loaded I just got an error that said "ERROR: No configuration file found No DEFAULT or UI configuration directive found!" After that it had "boot:" and a cursor, like it expects me to type something. Once again, this is just a normal install on my hard drive, not a VM or booting from USB. It's Ubuntu 12.04 on a Sony Vaio VGN-SZ240P Any help is appreciated!

• How can I set up a keyboard shortcut so that Ctrl+Backspace = Del?

  - by Palantir

  As an old mac user, I am used to hitting Ctrl+Backspace, and the effect is the same as if I pressed Del. I have recently purchased an Asus N53SV laptop which has replaced my MacBook, but unfortunately this laptop has a very annoying keyboard layout, where the Del key is in a non standard position, and moreover it is TINY. Is it possible to get the Ctrl+Backspace combination to issue a Del and how would I do this? Using Kubuntu, but I believe this is to be done at X level, not at desktop, am I right? Thanks!

• SSL is not enabled in Heroku

  - by Drom

  Since Heroku has integrated the piggybank_ssl addon by default, trying: heroku addons:add piggyback_ssl or heroku addons:add ssl:piggyback results in: ! This add-on is now a standard Heroku platform feature. ! Your apps can already use piggyback SSL. But, accessing: mywebsite.herokuapp.com results in: SSL is not enabled mywebsite.herokuapp.com does not have SSL enabled. My production.rb has: config.force_ssl = true What am I missing? Update I have read the page SSL on Heroku, but it's obsolete, they suggest to run: heroku addons:add piggyback_ssl Which is no longer necessary. SOLVED ! I don't change anything, and now it's working. It seems that it was a heroku problem.

• Web App vs Portal Platform - convincing the customer

  - by shinynewbike

  We're evaluating a set of requirements for a customer who wants Liferay which mainly has AAA and Web CMS requirements, and allowing user to upload their own content. Also all inetgration is via web services. However there is no need for other features such as actual "portlets", i18n, mashups, skins, themes, tagging, social presence, no collaboration etc So we feel we can do this as a standard JEE web app and not use Liferay (or any other portal product) since these are overheads we dont need. The customer feels the Web CMS requirements + user upload justify the "portal" product. Can anyone help me with some points to convince the customer? Assuming our point of view is right.

• Converting large files in python

  - by Cenoc

  I have a few files that are ~64GB in size that I think I would like to convert to hdf5 format. I was wondering what the best approach for doing so would be? Reading line-by-line seems to take more than 4 hours, so I was thinking of using multiprocessing in sequence, but was hoping for some direction on what would be the most efficient way without resorting to hadoop. Any help would be very much appreciated. (and thank you in advance) EDIT: Right now I'm just doing a for line in fd: approach. After that right now I just check to make sure I'm picking out the right sort of data, which is very short; I'm not writing anywhere, and it's taking around 4 hours to complete with that. I can't read blocks of data because the blocks in this weird file format I'm reading are not standard, it switches between three different sizes... and you can only tell which by reading the first few characters of the block.

• Handle all authentication logic in database or code?

  - by Snuffleupagus

  We're starting a new(ish) project at work that has been handed off to me. A lot of the database sided stuff has been fleshed out, including some stored procedures. One of the stored procedures, for example, handles creation of a new user. All of the data is validated in the stored procedure (for example, password must be at least 8 characters long, must contain numbers, etc) and other things, such as hashing the password, is done in the database as well. Is it normal/right for everything to be handled in the stored procedure instead of the application itself? It's nice that any application can use the stored procedure and have the same validation, but the application should have a standard framework/API function that solves the same problem. I also feel like it takes away the data from the application and is going to be harder to maintain/add new features to.

• About Intellectual-Property agreement with employer

  In IP agreement IP is define as below Intellectual Property (whether or not patentable and whether or not made during working hours) is defined as but not limited to: all product specifications, developments, inventions, works of authorship, derivative works, technologies, programs, systems, software, mobile applications and other mobile programming interfaces, designs, methodologies, encryptions, ideas, techniques, patents, formulas, processes, concepts, know-how and date made or conceived or reduced to practice or developed during employment period ,remain the property of XXXXXXX[COMPANY_NAME]XXXX or its affiliates.

• How access PhysicalMaterial from Actor Class?

  - by EmAdpres

  I use Projectile for my weapon system and UDKProjectile has two main function to handle Hit of projectiles(=bullet of my weapon): simulated function ProcessTouch(Actor Other, Vector HitLocation, Vector HitNormal) // For Actors simulated event HitWall(vector HitNormal, actor Wall, PrimitiveComponent WallComp) // Everything except Actors ( I guess) the first method, the function just give me the actor which I hit and my question is How I can get that actor's physical material by first parameter ( Other ), in order to make a proper react about it ( for example a proper Sound of collide ) ... A tricky (but hateful ) way which I knew works is, make a Trace from a little back of that actor to that actor, and use HitInfo parameter which include physical Material ! But there should be a more standard way !

• Is imposing the same code format for all developers a good idea?

  - by Stijn Geukens

  We are considering to impose a single standard code format in our project (auto format with save actions in Eclipse). The reason is that currently there is a big difference in the code formats used by several (10) developers which makes it harder for one developer to work on the code of another developer. The same Java file sometimes uses 3 different formats. So I believe the advantage is clear (readability = productivity) but would it be a good idea to impose this? And if not, why? UPDATE We all use Eclipse and everyone is aware of the plan. There already is a code format used by most but it is not enforced since some prefer to stick to their own code format. Because of the above reasons some would prefer to enforce it.

• Naming conventions for newtype deconstructors (destructors?)

  - by Petr Pudlák

  Looking into Haskell's standard library we can see: newtype StateT s m a = StateT { runStateT :: s -> m (a, s) } newtype WrappedMonad m a = WrapMonad { unwrapMonad :: m a } newtype Sum a = Sum { getSum :: a } Apparently, there (at least) 3 different prefixes used to unwrap a value inside a newtype: un-, run- and get-. (Moreover run- and get- capitalizes the next letter while un- doesn't.) This seems confusing. Are there any reasons for that, or is that just a historical thing? If I design my own newtype, what prefix should I use and why?

• Windows 7 doesnt boot after installing Ubuntu 12.10 (Asus Zenbook Prime / UEFI problem)

  - by jpdus

  Today I installed Ubuntu and since then i cannot boot into Windows anymore. I used the "standard" option (didnt change any partitions manually, just entered the size) but used the UEFI-mode. At first the GRUB entries for Windows did not work at all, after reading this thead i was able to add a new Grub entry - now i can get into the "windows-loading" screen for a few seconds but then i always see some kind of bluescreen for a fraction of a second and the laptop reboots. I can get into the windows recovery partition but the only option there is to reset everything to factory settings (+erase all data). I have no idea how to get into the Windows 7 repair mode which was mentioned here (tried everything else in this thread too - no success). My boot info can be found here: http://paste.ubuntu.com/1411573/ I have no idea what went wrong (there is even an extra page for the Zenbook Prime where no installation problems are mentioned). I would appreciate any help/ideas, many thanks!
