  • Where can I safetly search domain whois without worrying about the search engine parking on the domain immediately after the search?

    - by Evan Plaice
    There are a lot of companies that provide domain whois but I've heard of a lot of people who had bad experiences where the domain was bought soon after the whois search and the price was increased dramatically. Where can I gain access to a domain whois where I don't have to worry about that happening? Update: Apparently, the official name for this practice is called Domain Front Running and some sites go as far as to create explicit policies stating that they don't do it. This is where a domain registrar or an intermediary (like a domain lookup site) mines the searches for possibly attractive domains and then either sells the data to a third-party, or goes ahead and registers the name themselves ahead of you. In one case a registrar took advantage of what's known as the "grace period" and registered every single domain users looked up through them and held on to them for 5 days before releasing them back into the pool at no cost to themselves. Source: domainwarning.com And apparently, after ICANN was notified of the practice, they wrote it off as a coincidence of random 'domain tasting'. Source: See for yourself

  • Floating point equality and tolerances

    - by doron
    Comparing two floating point number by something like a_float == b_float is looking for trouble since a_float / 3.0 * 3.0 might not be equal to a_float due to round off error. What one normally does is something like fabs(a_float - b_float) < tol. How does one calculate tol? Ideally tolerance should be just larger than the value of one or two of the least significant figures. So if the single precision floating point number is use tol = 10E-6 should be about right. However this does not work well for the general case where a_float might be very small or might be very large. How does one calculate tol correctly for all general cases? I am interested in C or C++ cases specifically.

  • How to find out what Hackathons are coming up near me? [closed]

    - by codeulike
    I just went to my first hackathon (London GreenHackathon) and I want to go to lots more. Specifically, hackathons that have a theme of helping people or making the world a better place in some way. I know about Random Hacks of Kindness and a couple of others but is there some central aggregator that will help me find out about hackathons? Also, if anyone else can suggest specific hackathon initiatives I should check out that would be handy too. I'm in London but obviously for other people reading this question other locations will be of interest.

  • How to Override a private set property

    - by David
    Hi, Im using the Microsoft.Office.Interop.MSProject.Resource assembly which has a "UniqueID" property, it has a get but not set. How can I actually set a value? An example would be very much appreciated. --Update-- Ok I can get the value for a property "Name" and set, but Im intersted in the "UniqueId" property that does not have a public set (get only): int ii = (int)resource.GetType().InvokeMember("UniqueID", BindingFlags.GetProperty, null, resource, new object[] { }); resource.GetType().InvokeMember("UniqueID", BindingFlags.SetProperty, null, resource, new object[] {iUid,}); I get the following error {"Number of parameters specified does not match the expected number."} anyway for me to work out how many paramters it needs?

  • jQuery timer, ajax, and "nice time"

    - by Mil
    So for this is what I've got: $(document).ready(function () { $("#div p").load("/update/temp.php"); function addOne() { var number = parseInt($("#div p").html()); return number + 1; } setInterval(function () { $("#div p").text(addOne()); }, 1000); setInterval(function () { $("#geupdate p").load("/update/temp.php");} ,10000); }); So this grabs a a UNIX timestamp from temp.php and puts into into #div p, and then adds 1 to it every second, and then every 10 seconds it will check the original file to keep it up to speed. My problem is that I need to format this UNIX timestamp into a format such as "1 day 3 hours 56 minutes and 3 seconds ago", while also doing all the incrementation and ajax calls. I'm not very experienced with jquery/javascript, so I might be missing something basic.

  • How do I maximize a function in Mathematica which takes in a variable length list as input?

    - by Mike
    I have a time-series like function which gives an output based on a list of real numbers(i.e. you can run the function on a list of 1,2,3,... real numbers). The issue I'm encountering is how to maximize the function for a given list length(subject to a set of constraints). I could fix the function to a fixed number of real numbers(i.e. f [x_Real, y_Real] instead of f[x_List]) and treat x and y as the first two elements of the list, and call Maximize on the function, but this is not really elegant. I want to be able to easily change the number of elements in the list. What is the best way to optimize a function like I described, which takes a list as an argument, for a fixed list length?

  • PHP Round function

    - by Steve
    Is it possible to round a number where if it's 5 , just leave it , anything below 5 round down , anything above 5 round up? EX: 5 * 1.35 = 6.75 .... leave it 5.2 * 1.35 = 7.02 .... 7.00 5.5 * 1.35 = 7.56 .... 8.00 I've formatted with round($n,0, PHP_ROUND_HALF_UP) where $n is the product from the above calc , which leaves 6.75 but returns 7.02 for the next one. I also tried round($n,-1, PHP_ROUND_HALF_UP) which gives me the 7.00 on the second calc but then of course won't return a 6.75 for the first, instead it returns 680. This is a ticket markup calculation where the user enters the first number and is multiplied by the second. I actually remove the decimal because they don't want to see it, and they want this sort of customized rounding on the result. Thanks, Steve

  • I need to generate credit card surrogates (tokens) that are format preserving.

    - by jammer59
    For an eCommerce application I need to take a credit card and use the real card for passing through to a payment gateway but I need to store, and return to the transaction initiator, a surrogate that is format preserving. Specifically, this means: 1) The number of digits in the surrogate is the same as the real card number (PAN). 2) The issuer type part of the card -- the initial 1,2 or 4 digits remains the same in the surrogate as in the original PAN. 3) The final 4 digits of the surrogate remain the same (for customer service purposes.) 4) The surrogate passes the Luhn mod10 check for a syntactially valid credit card. I can readily handle requirements 1-3 but #4 has me completely stumped! The final implementation will be either t-sql or c#. Any ideas?

    When submitting a new app to the iPhone app store, which of these are mandatory, and which are optional? (Free apps... or paying apps.) A bank account with direct deposit access. An email address to give out to the public. An email address for Apple to contact me. A support website. A company name. A support phone number for the public. A phone number for Apple to call me. My full name given out to the public.

  • Finding an available network port on the machine

    - by Tomer Vromen
    I'm trying to implement a simple FTP server (a variation of the EFTP protocol) in linux. When a client connects and sends the PASV command, the server should respond with a port number, so the client can connect to that port to transmit the file. How can the server choose a port number? Do I need to iterate through all the ports from 1024 to 65535 until I find a port that the process can bind to? I know that calling bind() with 0 as the port automatically chooses the port to bind to, but then how can I know which port was chosen? Many thanks.

  • How to fire a bullet in a specific direction?

    - by Mike
    I am developing an Android game. I have problem with bullet firing. It's a space ship that has to fire bullets but right now it's firing in a random direction. I have to fire a bullet to the enemy from the only one point on the nose of the ship. Right now the bullets fire sometimes from the tailpart or other. So that's a problem. How do I give a bullet direction and how to fire it from only the head of my space ship?

  • thunderbird-bin causing CPU (core) lockup (12.04, 64bit, up-to-date)

    - by david6
    I have experienced 2-3 unexplained lockup over last 10 days. Today, I had a random lockup (no mouse, keyboard response, 100% CPU). But, when I finally switched (Ctrl-Alt-F1) to command line (it took several minutes) it told me that thunderbird-bin had locked a CPU. I ran this to resolve: pidof thunderbird-bin sudo kill #### However, after saving other work, I tried restarting Thunderbird. It went to 90%+ CPU, and within 20 seconds it locked again. Once I have more detail I will raise a bug (on Ubuntu Forums). Does anyone have any other suggestions, advice?

  • Setup suspend-on-lid-close/Fn+F4 outside of KDE/Gnome?

    - by maxschlepzig
    On current Ubuntu (10.04) suspend-on-lid/Fn+F4 only works if some powermanagement-applet of KDE/gnome is running. But what about suspend-to-lid if you are working on the console or using a non-bloated window-manager? What is the current mechanism to configure suspend-on-lid system wide? What of hald/udev/acpid/foo-kit/random-thing is the right place to hook this feature in? What is the up-to-date command to suspend from the command line/script? echo -n mem > /sys/power/state pm-suspend pmi or something else? Btw, if it matters, I want to configure it on some Thinkpads.

  • HTML5 clicking objects in canvas

    - by Dave
    I have a function in my JS that gets the user's mouse click on the canvas. Now lets say I have a random shape on my canvas (really its a PNG image which is rectangular) but i don't want to include any alpha space. My issue lies with lets say i click some where and it involves a pixel of one of the images. The first issue is how do you work out the pixel location is an object on the map (and not the grass tiles behind). Secondly if i clicked said image, if each image contains its own unique information how do you process the click to load the correct data. Note I don't use libraries I personally prefer the raw method. Relying on libraries doesn't teach me much I find.

  • Removing spam external links after pharma hack?

    - by Beatchef
    Back in February my work's site was attacked by a pharma hack at the shared hosting end. I managed to find the placed file and the reference to run it in one of our files. I deleted this file, deleted and redownloaded all of the plugins and themes and reinstalled Wordpress. However I could never find the database entries no matter what I have read up on. Searching for known entries or for drug names backwards etc. On the Google and Bing end I have managed to deny and delete the entries and cache of most if not all of the bad links that the hack managed to instantly SEO to death (why don't these guys work legit and make more money?) However the one thing that is remaining is external links on the homepage that are invisible except when the site is viewed in google cache or scanned with unmaskparasites.com (and says that the external links are safe even though they're obviously not!). http://www.UnmaskParasites.com/security-report/?page=kmcharityteam.co.uk All sorts of website scans say there's nothing wrong with it and I can't find the source of the links in the header or footer or anywhere in the theme. I've searched for the links in the database but no use there either and they change every day so really I'd have to be looking for a generator? Does anybody have any advice or a solution for removing these links? Thanks!

  • How do you go about checking your open source libraries for keystroke loggers?

    - by asd
    A random person on the internet told me that a technology was secure(1), safe to use and didn't contain keyloggers because it is open source. While I can trivially detect the key stroke logger in this open source application, what can developers(2) do to protect themselves against rouge committers to open source projects? Doing a back of the envelope threat analysis, if I were a rogue developer, I'd fork a branch on git and promote it's download since it would have twitter support (and a secret key stroke logger). If it was an SVN repo, I'd create just create a new project. Even better would be to put the malicious code in the automatic update routines. (1) I won't mention which because I can only deal with one kind of zealot at a time. (2) Ordinary users are at the mercy of their virus and malware detection software-- it's absurd to expect grandma to read the source of code of their open source word processor's source code to find the keystroke logger.

  • PHP Populating array with $variables

    - by Tom
    Hi, I'm trying to create a basic shopping cart, having an issue with the product page allowing users to add more items to their cart then are in stock (I have code in place to prevent this on the view cart page, just not the view product page) This is what I have so far; for ($i = 0; $i < $numItem; $i++) { extract($cartContent[$i]); $subTotal += $price * $cartQuantity; $cartLimiter[$itemNo => $cartQuantity]; Using an array so the position number becomes the item number and the cart quantity becomes the assigned value, however it doesn't seem to like it and throws out on the bottom line of code: Parse error: syntax error, unexpected T_DOUBLE_ARROW, expecting ']' Thanks

  • Are two database trips reasonable for a login system?

    - by Randolph Potter
    I am designing a login system for a project, and have an issue about it requiring two trips to the database when a user logs in. User types in username and password Database is polled and password hash is retrieved for comparative purposes (first trip) Code tests hash against entered password (and salt), and if verified, resets the session ID New session ID and username are sent back to the database to write a row to the login table, and generate a login ID for that session. EDIT: I am using a random salt. Does this design make sense? Am I missing something? Is my concern about two trips unfounded? Comments and suggestions are welcome.

  • DB2: Won't allow parameterize fetch first X rows only

    - by Guy Roth
    Although in Oracle DB its is allowed to parametrize the number of rows that the query can fetch by adding to the query: select ... from ... where ... and rownum <= @MaximumRecords I can't add similar condition to acuivalent query running in DB2: It is allowed to add: select ... from ... where ... fetch first 500 rows only (where there is fixed number of rows) but not: select ... from ... where ... fetch first :1 rows only (:1 == @MaximumRecords) Is someone aware of a solution/work-around to this problem?

  • ActiveRecord field normalization

    - by Bill
    I feel bad asking this question, as I thought I knew enough about Activerecord to answer this myslef. But such is the way of having SO available ... I'm trying to remove the commas from a field in a model of mine, I want the user to be able to type a number , ie 10,000 and that number be stored in the database as 10000. I was hoping that I could do some model-side normalization to remove the comma. I don't want to depend on the view or controller to properly format my data. I tried ; before_validation :normalize def normalize self['thenumber'] = self['thenumber'].to_s.gsub(',','') end no worky :(

  • Debugging OpenOffice crashes

    - by JD Long
    This is partly an OpenOffice question and partly a Ubuntu question. I'm running OpenOffice 3.2.0 and Ubuntu 10.04. I get frequent crashes of OO, especially the Calc app, although I get crashes in the word processor as well. They are very abrupt and accompanies by no warning or error message. I'm just typing away and then the app is gone. Sometimes I even end up thinking I'm typing in OO and discover that OO has crashed and I'm typing in whatever application was under OO. However, I can't reproduce these crashes on demand. They seem random. I can open the same file and do the same exact thing but it does not crash. In Ubuntu how do I trace, track, or diagnose these types of crashes? Is there software I can invoke to help diagnose? Can I start OO from a command prompt with debugging of some sort enabled? Note: if someone could add the tag OpenOffice, I would appreciate it
