  • Is it worth it to learn some programming before college?

    - by Howlgram
    I'm in my last year of highschool and I am very interested in programming, the thing is I don't know if it could be worth it to start learning programming now, im afraid that when I get to college they might just teach all I might have learned in a few classes making a waste the time spent on learning that before college. Right now I'm on my last year of highschool and I know absolutely nothing about programming. There are other similar questions where people answer saying it is good to learn beforehand, but I doubt their situation might be like mine, maybe they had much more time to learn programming (as if they were not on their last year of highschool) before college so they could learn some serious skills, besides they say they already know at least the basics about a language, instead, I know nothing and I have no idea how much could I learn this year. If it wasn't clear I want to study computer's science

  • Using Markov models to convert all caps to mixed case and related problems

    - by hippietrail
    I've been thinking about using Markov techniques to restore missing information to natural language text. Restore mixed case to text in all caps Restore accents / diacritics to languages which should have them but have been converted to plain ASCII Convert rough phonetic transcriptions back into native alphabets That seems to be in order of least difficult to most difficult. Basically the problem is resolving ambiguities based on context. I can use Wiktionary as a dictionary and Wikipedia as a corpus using n-grams and Markov chains to resolve the ambiguities. Am I on the right track? Are there already some services, libraries, or tools for this sort of thing? Examples GEORGE LOST HIS SIM CARD IN THE BUSH - George lost his SIM card in the bush tantot il rit a gorge deployee - tantôt il rit à gorge déployée

  • Is programming as a career in the US being hurt by competition from programmers in India?

    - by compman
    I don't want to be offensive; people in India matter just as much as people in the US and also need work. However, I'm one of the people in the US. Are there fewer programming jobs in the US because of competition from India? Are the programming jobs in the US less lucrative because of competition from India? Is programming a good career choice in the US (in terms of being able to actually make a fair amount of money)?

  • remove words containing non-alpha characters

    - by dnkb
    Given a text file with space separated string and a tab separated integer, I'd ;like to get rid of all words that have non-alpha characters but keep words consisting of alpha only characters and the tab plus the integer afterwards. My attempts like the ones below didin't yield any good. What I was trying to express is something like: "replace anything within word boundaries that starts and ends with 0 or more whatever and there is at least one :digits: or :punct: in between". sed 's/\b.[:digits::punct:]+.\b//g' sed 's/\b.[^:alpha:]+.\b//g' What am I missing? See sample input data below. Thank you! asdf 754m 563 a2a 754mm 291 754n 463 754 ppp 1409 754pin 4652 pin pin 462 754pins 652 754 ppp 1409 754pin 4652 pi$n pin 462 754/p ins 652 754 pp+p 1409 754 p=in 4652

  • Removing related elements using XSLT 1.0

    - by pmdarrow
    I'm attempting to remove Component elements from the XML below that have File children with the extension "config." I've managed to do this part, but I also need to remove the matching ComponentRef elements that have the same "Id" values as these Components. <Fragment> <DirectoryRef Id="MyWebsite"> <Component Id="Comp1"> <File Source="Web.config" /> </Component> <Component Id="Comp2"> <File Source="Default.aspx" /> </Component> </DirectoryRef> </Fragment> <Fragment> <ComponentGroup Id="MyWebsite"> <ComponentRef Id="Comp1" /> <ComponentRef Id="Comp2" /> </ComponentGroup> </Fragment> Based on other SO answers, I've come up with the following XSLT to remove these Component elements: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes" /> <xsl:template match="Component[File[substring(@Source, string-length(@Source)- string-length('config') + 1) = 'config']]" /> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> Unfortunately, this doesn't remove the matching ComponentRef elements (i.e. those that have the same "Id" values). The XSLT will remove the component with the Id "Comp1" but not the ComponentRef with Id "Comp1". How do I achieve this using XSLT 1.0?

  • How to create instances of related models in Django

    - by sevennineteen
    I'm working on a CMSy app for which I've implemented a set of models which allow for creation of custom Template instances, made up of a number of Fields and tied to a specific Customer. The end-goal is that one or more templates with a set of custom fields can be defined through the Admin interface and associated to a customer, so that customer can then create content objects in the format prescribed by the template. I seem to have gotten this hooked up such that I can create any number of Template objects, but I'm struggling with how to create instances - actual content objects - in those templates. For example, I can define a template "Basic Page" for customer "Acme" which has the fields "Title" and "Body", but I haven't figured out how to create Basic Page instances where these fields can be filled in. Here are my (somewhat elided) models... class Customer(models.Model): ... class Field(models.Model): ... class Template(models.Model): label = models.CharField(max_length=255) clients = models.ManyToManyField(Customer, blank=True) fields = models.ManyToManyField(Field, blank=True) class ContentObject(models.Model): label = models.CharField(max_length=255) template = models.ForeignKey(Template) author = models.ForeignKey(User) customer = models.ForeignKey(Customer) mod_date = models.DateTimeField('Modified Date', editable=False) def __unicode__(self): return '%s (%s)' % (self.label, self.template) def save(self): self.mod_date = datetime.datetime.now() super(ContentObject, self).save() Thanks in advance for any advice!

  • Localizing non-breaking space in Windows 8

    - by Lukas_Skywalker
    I'm trying to localize a Windows 8 Metro style app as described in a guide on MSDN. This worked very well so far, but now I'm trying to localize a string containing a non-breaking space which appears in a XAML file (originally as hexadecimal xml-escaped string: &#x00a0). Just putting the above string into the Resources.resw file does not work, it appears just as &#x00a0. What do I have to do to get a non-breaking space in my localizations?

    - by z22
    I have 2 tables Users and Artists. User: id name password city_id state_id country_id Artist: id user_id description I wish to create add and edit form(single form acts as add and edit). But on click of edit link, I wish to fill in the form fields from user as well as artist table. How do i do that? Below is my controller code: public function artist_register() { $this->country_list(); if ($this->request->is('post')) { $this->request->data['User']['group_id'] = 2; if ($this->{$this->modelClass}->saveAll($this->request->data)) { $this->redirect(array('controller' => 'Users', 'action' => 'login')); } } $this->render('artist_update'); } public function artist_update($id) { $artist = $this->{$this->modelClass}->findByuser_id($id); $artist_id = $artist[$this->modelClass]['id']; if($this->request->is('get')) { $this->request->data = $this->{$this->modelClass}->read(null, $artist_id); $this->request->data = $this->{$this->modelClass}->User->read(null, $id); } else { if($this->{$this->modelClass}->save($this->request->data)) { $this->Session->setFlash('Your Profile has been updated'); $this->redirect(array('action' => 'index')); } } } The code doesnt work. how do i solve it?

  • Allowing non-admins to run programs as admins on Windows 7

    - by Josh
    On *nix, admins can use the setuid flag to allow non-admins to run certain programs that would otherwise require admin privileges. Is there any way to do something similar in Windows 7? This question has been asked here before for Windows XP, and the answers were generally unsatisfying. I'm wondering if Windows 7 provides a better way. One idea I can think of would be to use Microsoft's Subsystem for UNIX Applications, but I'd rather not install that on every user's system if I can avoid it. Another idea I can think of (which would work on XP too, but I haven't seen it mentioned anywhere) would be to create a RunAsAdmin application that runs as a service, that takes a whitelist of "safe" apps and can be asked (from a command line, batch file or script) to run any program on the list as LocalSystem or whatever account the service uses. Is this possible? Are there any solutions that aren't as clunky as those? Or, has anyone implemented either of the above techniques successfully?

  • Visual Studio crashes consistently on web-related projects

    - by Traveling Tech Guy
    Hi, I have a brand new VS2010 installed on a Win2008R2 machine. I started getting this error when debugging a WCF service project: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." When I started developing a web site a week later, this became consistent - I can't debug it. The stack dump reads: at Microsoft.VisualStudio.WebHost.Host.ProcessRequest(Connection conn) at Microsoft.VisualStudio.WebHost.Server.OnSocketAccept(Object acceptedSocket) at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem() at System.Threading.ThreadPoolWorkQueue.Dispatch() at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback() I tried searching online, and some recommend turning off the "Suppress JIT Optimizations" in the Debugging options - this dos not seem to make a difference. Clearly the problem is with the built in web server. But am I doing something wrong? Is there something I can do? Or is this a known bug? Thanks for your time, Guy Update 12/31: Today I tried using CassiniDev as a replacement to the original VS2010 WebServer - exact same result. My suspicion is that there's some internal conflict between VS2010, Windows Server 2008R2 and maybe the fact that it's a 64 bit OS. I switched to using IIS as my debug server - and that seems to work, with some annoying side effects. My conclusion: do not use a 64 bit server system as your dev machine. Develop on 32bit - deploy to 64bit. Side conclusion: there are some scenarios Microsoft's QA doesn't test.

  • Django filter with two constraints on related model

    - by BJ Homer
    I have a django app with models as follows: A Question model An Answer model, with a ForeignKey back to the Question. (A question can have multiple answers.) A Flag model, with a ForeignKey to the Answer. (An answer can be flagged as inappropriate.) All of the above also have a user field, defining the user that created that object. I'm trying to get a list of all Questions with answers from the current user which have been flagged. I tried this: Question.objects.filter(answer__user=user).\ filter(answer__flag__isnull=True).distinct() … but I believe that will return a list of Questions with answers from the current user and with answers which have been flagged, but will not necessarily guarantee that it is the user's answer that has been flagged. Is there an easy way to do this? Basically, I want to make the answer part of the filter refer to the same answer on both of them. Please let me know if something is unclear.

  • Recommendation for a non-standard SSL port

    - by onurs
    Hey guys, On our server I have a single IP, and need to host 2 different SSL sites. Sites have different owners so have different SSL certificates, and can't share the same certificate with SAN. So as a last resort I have modified the web application to give the ability to use a specified port for secure pages. For its simple look I used port 200. However I'm worried about some visitors may be unable to see the site because of their firewalls / proxies blocking the port for ssl connections. I heard some people were unable to see the website, a home user and someone from an enterprise company, don't know if this was the reason. So, any recommendations for a non-standard SSL port number (443 is used by the other site) which may work for visitors better than port 200 ? Like 8080 or 8443 perhaps? Thanks!

    I have a WPF textbox, and perform the following actions Enter text as "12345" Move cursor between 3 and 4 (using arrow or mouseclick) Enter 0 (so Text is now "123045") Which event/eventargs can tell me that 0 was typed at location 4. I need to know this at Preview level so that I can reject the character 0 based on the prefixed and suffixed digits.

  • Serving static web files off a non-standard port

    - by Nimmy Lebby
    I'm close to deploying a Django project to production. I'm looking over some infrastructure decisions. Something that came up was serving static files with a different server such as lighttpd. However, we're starting off with a single dedicated server so our only option would be to use a non-standard port for the static file webserver. Is there precedence for this? I.e. Does anyone "big" do this? Any particular port I should use or shy away from using? Can anyone thing of some downsides of going this route?
