  • Failed to allocate memory - What is it trying to say?

    - by asprin
    In my early days of programming I often used to get memory related fatal errors in the following format: Fatal error: Allowed memory size of <some big number> bytes exhausted (tried to allocate <some small number> bytes) in /path/to/filename.php on line <some line number> I'm a little embarrassed to state that even though I have figured out how to solve them and take steps to avoid them altogether, I'm still not quite sure what exactly does the message translate to in simple words. For example, if I get a message such as: Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 4000 bytes) in ........ on line 34 As things stand at the moment, I assume it to be stating that the script consumes 67108864 bytes of data, but only 4000 bytes are available during runtime. Am I right in my assumption? If not, what's the correct interpretation?

  • Why does Windows 7 overall performance is better than Ubuntu 11.10?

    - by user37805
    I have a i7 2600 processor, 8Gb DDR3 ram, nVidia GTX570, and Ubuntu takes 45-50 seconds to boot and 32-35 seconds to power off, while windows 7 boots in 20-25 seconds and shuts down in 10 seconds. Both OS with autologin enabled, and in dual boot. Ubuntu is slow with preload too, and doesn't show any boot splash after installing drivers and didn't recognize my nVidia graphics card on jockey GTK, I had to add x swat repository and that didn't worked. I installed proprietary drivers through terminal (nvidia-common, nvidia-settings) in order to have 3d acceleration. But it doesn't make any difference on the speed. I also have a Pentium 4 PC and ubuntu 11.10 is way faster than windows 7 or XP. Also with nvidia graphics card and preload. http://paste.ubuntu.com/924890/ there is my boot script, sorry but some words are in Spanish because my ubuntu is in Spanish. Not using WUBI, Ubuntu has its own partition, 64-bits, and Matlab 2011 has very low performance compared to windows version.

  • How to completely remove Ubuntu?

    - by les02jen17
    I installed Ubuntu using Wubi installer, but I couldnt boot to it. So I uninstalled it on the Control Panel. Then I tried the full installation wherein it boots to the Ubuntu environment. After installing Ubuntu there, I couldnt boot to my Windows 7 anymore! So in an attempt to salvage the whole thing, I inserted the Ubuntu CD again and chose Erase Ubuntu and Reinstall. (I was wondering, why wasn't there an option to just "Erase Ubuntu"?) I did that though, and I got my Windows 7 back. But upon checking my drives via the "Create your own partition scheme" (not sure if it's the exact words) I saw that one of my partitions still has Ubuntu on it, and there's no way I can delete it if I don't overwrite another Ubuntu! I can't access that partition on windows 7 either! Need help!

  • Moving from an IT department to a proper technology company

    - by user2434
    I have been working with Java/web applications in an IT department of a retail company. As much as work goes, there is nothing much to say. Fixing couple of if/else loops, writing some simple business logic etc., is all what I have been doing. Having said that, I feel I have a good technical knowledge, and I am willing to move to companies like Microsoft/Google/Amazon etc., [I want to work in these places, because I feel I am a technical guy, and I am working in a place where most people freak out when the words like 'algorithm' are heard] I can of course prepare algorithms/computer science fundamentals etc.,(I hold a 4 year degree in computer science program) but beyond that, will my experience hold against me ? I doubt I'll even get a call from them seeing my work experience. What kind of questions(apart from the algorithm types) can I expect ?

  • Could multiple uses of the same keywords in image alt attributes hurt SEO?

    - by saratogahiker
    Let's say on an e-commerce site that sells unique pens, on a particular pen's product page, the image of the pen has an alt attribute value of "unique red-striped pen"... and another product has "unique blue-spotted pen", etc... The keywords across all products being "unique" and "pen", which would also be helpful when it comes to SEO. However, if the person just goes to the general "unique pens" category page and sees a list of thumbnail images, each with the words "unique" and "pen" in the alt attribute, would that potentially have a negative impact with regards to SEO by having the same keywords too many times?

  • Checking a record is due based on the 'occuring' field

    - by andy
    I have records that have dates against them and an occurring field that contains none,yearly and monthly id status note date last_updated occurring 1 open --- 01/01/2011 01/02/2010 yearly 2 open --- 05/05/2011 03/05/2011 monthly 3 open --- 06/06/2011 05/06/2011 none Now I need to be able to check if a record is due (the date set has passed) which works perfect if occurring is set to none but I'm unsure of how to approach it when it's set to yearly or monthly (IE: This day in the year/month has passed) So with the above records, if I had a method on the record called due? providing the status is 'open' it needs to return true every year when it's passed that date if it's not been updated within the year yet. I apologise if this is confusing but it's melting my brain just trying to think of it, let alone put it into words.

  • oDesk agency for subcontracting

    - by lorddev
    My question has to do with whether to create an oDesk agency (I've searched to verify that oDesk questions are appropriate). I have a project for which I was hired, and the client has given me authorization to subcontract a few hours of UI/UX expertise. I don't want to make the client hire the UI/UX guy directly; however, if I hire someone with my company account and then bill the client for the time, oDesk is taking 19% off the top (10% twice). I've checked their FAQ and filed a support ticket several days ago, but nobody has replied. If there's anyone who has had experience with oDesk agencies, do you think it can be handled this way? In other words, can I be the developer in my own agency while also having a UX person on the team?

  • Developing a search algorithm

    - by Richart Bremer
    I want to create a basic search engine, and I want you to give me some ideas how to filter out the best results for my visitors. I have three fields regarding a product the user can search in: Title Category Description I came up with these ideas and I ask you to either competently criticize them or add to them. If the search term occurs in all three fields it should be among the first results. If it is in two of the fields it is below the results of 1. Combine the amount of occurences and output a value in per cent. For instance if in all fields together the term clock appeared 50 times and in all fields together there are 200 words, then the per cent value is 50/200*100 = 25%. Another product entry amounts to say 20% so product one having 25% is listed before product two having 20%.

  • A look at an example of anti-spam algorithm

    - by pragmaticCamel
    What is a good approach to an anti-spam algorithm for a website similar to reddit? Their anti-spam algorithm seems awfully broken (banning on words in the title and doing a horrible job for that matter). Considering a post spam because it has the word 'spam' in the title is really not a wise choice. Anyway, how can one approach such problem ? Are there any tools that help in such cases? Also, what are the /technical/ reasons behind reddit's choice not using reCAPTCHA on every post submission? It seems like a much better solution than what they have right now. Since reddit is basically a community-driven website why not give such power to the communities' trusted members?

  • What to use to make voice chat (and some more) on a web?

    - by Tunococ
    I am trying to make available on my website a voice chat for a small group of people that allows some other means to interact such as text messaging, photo sharing, file sharing, simple drawing and silly games. In other words, something similar to older MSN Messenger, but on the web. Any ideas on what to use? To clarify, I am looking for suggestions on languages and libraries to use. I want to be able to fully customize it as much as possible because I might want to add other (somewhat interesting) functions later. Low-level programming is fine if required, but platform dependency isn't that much preferred.

  • How do you assign commands to keys to in Terminal?

    - by NES
    Is there a solution to assign special key combinations to words in terminal use. For example the less command is very usefull and i use i a lot to pipe the output of another process through it. The idea would be to set up special key combinations that are only active in terminal use assigned to write different commands? So pressing CTRL + l in terminal window could write | less or CTRL + G could stand for | grep Note: i just mean adding the letters to commandline not execute the finally. A similar way what's tabcompletion but more specific.

  • .htaccess two different rules but only one per time

    - by dragon112
    I'm rather new to the whole .htaccess thing and I'm using the following right now to use 'pretty url's': <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?path=$1 [NS,L] </IfModule> Now i found my website a bit slow and decided to start gzipping my CSS files thru a php script I found somewhere on the web (the website). For this to work I need to rewrite the url to open the correct php file. That would look something like this: RewriteRule ^(.*).css$ /csszip.php?file=$1.css [L] But I only want the first to happen when the second doesn't and vice versa. In other words i'd like something like this: <IfModule mod_rewrite.c> RewriteEngine On if request doesn't contain .css do RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?path=$1 [NS,L] else do RewriteRule ^(.*).css$ /csszip.php?file=$1.css [L] </IfModule> Can anyone help me with the proper code or a place where i can find a way to use some kind of conditional statement in htaccess files? Thanks in Advance!:)

  • If I have true i/o false or vice versa, is it an OBOE?

    - by Protector one
    I often make the mistake of inverting my truth values in my code (e.g. in my if clauses). It gives me the same feeling as when making an OBOE (Off By One Error), even though it's technically not. Would you call it an OBOE, or better yet, is there a specific term for "off by truth value"-errors? My reasoning is that all possible values of a boolean are true and false. In other words, the possible values are contained in the array: [true, false]. If you access this array by index, you'll always be off by one… when selecting the wrong one. This becomes especially obvious when you calculate your index as: index = someInt % 2. Now I understand that this usually not the case, but in my mind, it always feels like this. Almost got it, just off by one…

  • How can you identify duplicate CSS rules?

    - by DanMan
    I'm not talking about used/unused here. I have two stylesheets and some rules differ (either in selectors, rules or both) and some are exactly the same. So I'm looking for a way to extract and move those rules, which are the same in both files, into a third stylesheet. In other words: an intersection of two stylesheets. Strangely, I couldn't find a software for this. Would have expected this to be a more common problem. Background, for those who care: I'm converting a desktop website into a mobile one and I've started by duplicating the desktop stylesheet and changing it (throwing stuff out, adding to it).

  • What can I do to make my eService website customers feel it is a luxurious service? [closed]

    - by Farshid
    I'm developing an e-service website that its monetization model is via paid membership. Beside quality service and content, because I'm serving them for a high fee, I want to make them feel like it is a personal, unparalleled kind of service and I want to spend money for creating things that I give them after their registration such as a beautiful physical membership card so that I can use the effect of mouth-words better and beside that let them be proud about the service. I've tried my best to develop the site experience classy and I'm looking for things in real world to send them after their registration (such as membership card and a small paper tutorial). What are your suggestions? Have you seen things like this before that a website sends you some physical things for making you more loyal and/or something like that? Please kindly share your experiences/suggestions.

  • How can I ensure reasonably spaced out enemies

    - by Samuraisoulification
    I have a simple javascript game and I'm initializing their positions on the y axis using random numbers. How can I ensure that they are reasonably spaced apart? My simple algorithm is: y = (Math.random()*1000%600); However I frequently get enemies almost directly on top of each other. This is a huge problem for the game, since it's a word game and the enemies have text on their center, that if overlapped makes them impossible to kill since you can't see the words. Any advice would be appreciated! I'm pretty new to making games in general so this has all been a learning experience for me!

  • Using <strong> for introductory paragraph to a post - a bad idea?

    - by user1515699
    I have a news website and on most posts the first paragraph is in bold. Currently the authors are just using <strong> to bold the paragraph, would it be better from an SEO point of view to rather use a paragraph class that is styled with p.bold {font-weight:bold;} <p class="bold">. Does <strong> on the first paragraph send the wrong message to search engines? The text is important but the main reason it is in bold is because it is the opening paragraph. I realise <strong> is used to emphasise certain words on a page

  • Slow tranfer to external USB3 hard drive

    - by JMP
    Trying to backup data from hard drive before reloading windows following some issue with its load. Having trouble with the file transfer to a USB3/2 external hard drive NTFS. Getting transfer speed of about 116.7kB/sec. In other words its taking about 5 hours to tranfer 1.4GB. I've got about 80GB to go. So the transfer is going to take 11days. Seems a little on the slow side. Am I missing something? Is there a way to make this faster. No issue with the external drive tranferring this amount in windows. But don't have that option at the moment.

  • BeansBinding Across Modules in a NetBeans Platform Application

    - by Geertjan
    Here's two TopComponents, each in a different NetBeans module. Let's use BeansBinding to synchronize the JTextField in TC2TopComponent with the data published by TC1TopComponent and received in TC2TopComponent by listening to the Lookup. The key to getting to the solution is to have the following in TC2TopComponent, which implements LookupListener: private BindingGroup bindingGroup = null; private AutoBinding binding = null; @Override public void resultChanged(LookupEvent le) { if (bindingGroup != null && binding != null) { bindingGroup.getBinding("customerNameBinding").unbind(); } if (!result.allInstances().isEmpty()){ Customer c = result.allInstances().iterator().next(); // put the customer into the lookup of this topcomponent, // so that it will remain in the lookup when focus changes // to this topcomponent: ic.set(Collections.singleton(c), null); bindingGroup = new BindingGroup(); binding = Bindings.createAutoBinding( // a two-way binding, i.e., a change in // one will cause a change in the other: AutoBinding.UpdateStrategy.READ_WRITE, // source: c, BeanProperty.create("name"), // target: jTextField1, BeanProperty.create("text"), // binding name: "customerNameBinding"); bindingGroup.addBinding(binding); bindingGroup.bind(); } } I must say that this solution is preferable over what I've been doing prior to getting to this solution: I would get the customer from the resultChanged, set a class-level field to that customer, add a document listener (or action listener, which is invoked when Enter is pressed) on the text field and, when a change is detected, set the new value on the customer. All that is not needed with the above bit of code. Then, in the node, make sure to use canRename, setName, and getDisplayName, so that when the user presses F2 on a node, the display name can be changed. In other words, when the user types something different in the node display name after pressing F2, the underlying customer name is changed, which happens, in the first place, because the customer name is bound to the text field's value, so that the text field's value will also change once enter is pressed on the changed node display name. Also set a PropertyChangeListener on the node (which implies you need to add property change support to the customer object), so that when the customer object changes (which happens, in the second place, via a change in the value of the text field, as defined in the binding defined above), the node display name is updated. In other words, there's still a bit of plumbing you need to include. But less than before and the nasty class-level field for storing the customer in the TC2TopComponent is no longer needed. And a listener on the text field, with a property change listener implented on the TC2TopComponent, isn't needed either. On the other hand, it's more code than I was using before and I've had to include the BeansBinding JAR, which adds a bit of overhead to my application, without much additional functionality over what I was doing originally. I'd lean towards not doing things this way. Seems quite expensive for essentially replacing a listener on a text field and a property change listener implemented on the TC2TopComponent for being notified of changes to the customer so that the text field can be updated. On the other other hand, it's kind of nice that all this listening-related code is centralized in one place now. So, here's a nice improvement over the above. Instead of listening for a customer, listen for a node, from which the customer can be obtained. Then, bind the node display name to the text field's value, so that when the user types in the text field, the node display name is updated. That saves you from having to listen in the node for changes to the customer's name. In addition to that binding, keep the previous binding, because the previous binding connects the customer name to the text field, so that when the customer display name is changed via F2 on the node, the text field will be updated. private BindingGroup bindingGroup = null; private AutoBinding nodeUpdateBinding; private AutoBinding textFieldUpdateBinding; @Override public void resultChanged(LookupEvent le) { if (bindingGroup != null && textFieldUpdateBinding != null) { bindingGroup.getBinding("textFieldUpdateBinding").unbind(); } if (bindingGroup != null && nodeUpdateBinding != null) { bindingGroup.getBinding("nodeUpdateBinding").unbind(); } if (!result.allInstances().isEmpty()) { Node n = result.allInstances().iterator().next(); Customer c = n.getLookup().lookup(Customer.class); ic.set(Collections.singleton(n), null); bindingGroup = new BindingGroup(); nodeUpdateBinding = Bindings.createAutoBinding( AutoBinding.UpdateStrategy.READ_WRITE, n, BeanProperty.create("name"), jTextField1, BeanProperty.create("text"), "nodeUpdateBinding"); bindingGroup.addBinding(nodeUpdateBinding); textFieldUpdateBinding = Bindings.createAutoBinding( AutoBinding.UpdateStrategy.READ_WRITE, c, BeanProperty.create("name"), jTextField1, BeanProperty.create("text"), "textFieldUpdateBinding"); bindingGroup.addBinding(textFieldUpdateBinding); bindingGroup.bind(); } } Now my node has no property change listener, while the customer has no property change support. As in the first bit of code, the text field doesn't have a listener either. All that listening is taken care of by the BeansBinding code.  Thanks to Toni for help with this, though he can't be blamed for anything that is wrong with it, only thanked for anything that is right with it.

  • How to compare page views/visitors to site totals in Google Analytics?

    - by frntk
    I want to measure the effects in total traffic (views or visitors) of a single URL across a time frame. For example, let's say I published a blog post on July 2012. I want to measure what chunk of the site's total traffic is coming to this particular post on a month-by-month graph from July 2012 to date. Is there a way to do this? Edit: I should clarify that what I'd like to do is to generate a month-to-month graph, similar to the one you can see comparing a metric on a period of time against the previous equivalent period (year vs last year, for example) but comparing a particular URL traffic to the site's total traffic. In other words, I can get to the part where I can see the URL's traffic for the timeframe I selected and it shows how much of the total traffic corresponds to the current URL: But I'd like to add a second line to the graph, representing the site's total pageviews, similiar to this (but this one is showing just a different metric for the same URL): Thanks!
