• How to learn to program [on hold]

  - by user94914

  I went to a community college and got a degree in computer science, but I found out I only learn very little about programming. As a result I landed byself a office assistant work (for a year now), I want to study on my own and apply for some internship / very entry level development job. I am wondering how should a person learn to program now? I feel that I might not doing it correctly, I understand everyone has a different approach, but I am really clueless on what to do, as it seems I am 5-10 years away. 1) Read the old college programming textbook cover to cover, learn every single concepts, do all the practice problems and master them (1-2 times until error free). Currently reading this java book 2) Work on any project, keep on googling and reading tutorials (including the books on that specific language). I have been doing 1, but the progress is really slow, about 2-5 pages / hour, over a 1000+ page book, I felt really discouraged. I have a few of them to go through (data struction, analyis algorthim, computer theory, operating system.) I wonder is this the right method to do? I know it is going to take time, but I am hoping to get some advice from current programmers.

• I bought a new battery and Ubuntu 12.10 isn't recognizing it

  - by user134403

  I inherited my mom's old laptop and installed Ubuntu over top of Vista, so now it is purely Ubuntu. Her old battery only lasted about 10 minutes, so it had to be plugged in all the time, which I didn't like. So I bought a battery, and inserted it in when it came. The laptop doesn't see it at at all- no battery icon whatsoever. I can pull it out and put the old battery in and it recognizes it. The new battery comes with a program (a .exe) to update the bios to accommodate the new battery... But don't have Windows anymore and Wine gives me an error when I try to run it, so I am at a loss of ideas. I thought of running a virtual machine of Windows to install it, or run a Windows To Go drive(a new feature of Windows 8), but I don't think those are good ideas as they may not work or permanently ruin something. I am not an extremely experienced user of Ubuntu/Linux, so I don't where to go from here. I'm running Ubuntu 12.10 on a Sony Vaio VGN-NR, if that helps. Also note that I just installed Ubuntu the other day and have nothing important on the pc yet, so I am not afraid to reinstall Ubuntu if it may help. Thanks!

• Are my negative internship experiences respresentative of the real world?

  - by attemptAtAnonymity

  I'm curious if my current experiences as an intern are representative of actual industry. As background, I'm through the better part of two computing majors and a math major at a major university; I've aced every class and adored all of them, so I'd like to think that I'm not terrible at programming. I got an internship with one of the major software companies, and half way through now I've been shocked at the extraordinarily low quality of code. Comments don't exist, it's all spaghetti code, and everything that could be wrong is even worse. I've done a ton of tutoring/TAing, so I'm very used to reading bad code, but the major industry products I've been seeing trump all of that. I work 10-12 hours a day and never feel like I'm getting anywhere, because it's endless hours of trying to figure out an undocumented API or determine the behavior of some other part of the (completely undocumented) product. I've left work hating the job every day so far, and I desperately want to know if this is what is in store for the rest of my life. Did I draw a short straw on internships (the absurdly large paychecks imply that it's not a low quality position), or is this what the real world is like?

• Java Program help [migrated]

  - by georgetheevilman

  Okay I have a really annoying error. Its coming from my retainAll method. The problem is that I am outputting 1,3,5 in ints at the end, but I need 1,3,5,7,9. Here is the code below for the MySet and driver classes public class MySetTester { public static void main(String[]args) { MySet<String> strings = new MySet<String>(); strings.add("Hey!"); strings.add("Hey!"); strings.add("Hey!"); strings.add("Hey!"); strings.add("Hey!"); strings.add("Listen!"); strings.add("Listen!"); strings.add("Sorry, I couldn't resist."); strings.add("Sorry, I couldn't resist."); strings.add("(you know you would if you could)"); System.out.println("Testing add:\n"); System.out.println("Your size: " + strings.size() + ", contains(Sorry): " + strings.contains("Sorry, I couldn't resist.")); System.out.println("Exp. size: 4, contains(Sorry): true\n"); MySet<String> moreStrings = new MySet<String>(); moreStrings.add("Sorry, I couldn't resist."); moreStrings.add("(you know you would if you could)"); strings.removeAll(moreStrings); System.out.println("Testing remove and removeAll:\n"); System.out.println("Your size: " + strings.size() + ", contains(Sorry): " + strings.contains("Sorry, I couldn't resist.")); System.out.println("Exp. size: 2, contains(Sorry): false\n"); MySet<Integer> ints = new MySet<Integer>(); for (int i = 0; i < 100; i++) { ints.add(i); } System.out.println("Your size: " + ints.size()); System.out.println("Exp. size: 100\n"); for (int i = 0; i < 100; i += 2) { ints.remove(i); } System.out.println("Your size: " + ints.size()); System.out.println("Exp. size: 50\n"); MySet<Integer> zeroThroughNine = new MySet<Integer>(); for (int i = 0; i < 10; i++) { zeroThroughNine.add(i); } ints.retainAll(zeroThroughNine); System.out.println("ints should now only retain odd numbers" + " 0 through 10\n"); System.out.println("Testing your iterator:\n"); for (Integer i : ints) { System.out.println(i); } System.out.println("\nExpected: \n\n1 \n3 \n5 \n7 \n9\n"); System.out.println("Yours:"); for (String s : strings) { System.out.println(s); } System.out.println("\nExpected: \nHey! \nListen!"); strings.clear(); System.out.println("\nClearing your set...\n"); System.out.println("Your set is empty: " + strings.isEmpty()); System.out.println("Exp. set is empty: true"); } } And here is the main code. But still read the top part because that's where my examples are. import java.util.Set; import java.util.Collection; import java.lang.Iterable; import java.util.Iterator; import java.util.Arrays; import java.lang.reflect.Array; public class MySet implements Set, Iterable { // instance variables - replace the example below with your own private E[] backingArray; private int numElements; /** * Constructor for objects of class MySet */ public MySet() { backingArray=(E[]) new Object[5]; numElements=0; } public boolean add(E e){ for(Object elem:backingArray){ if (elem==null ? e==null : elem.equals(e)){ return false; } } if(numElements==backingArray.length){ E[] newArray=Arrays.copyOf(backingArray,backingArray.length*2); newArray[numElements]=e; numElements=numElements+1; backingArray=newArray; return true; } else{ backingArray[numElements]=e; numElements=numElements+1; return true; } } public boolean addAll(Collection<? extends E> c){ for(E elem:c){ this.add(elem); } return true; } public void clear(){ E[] newArray=(E[])new Object[backingArray.length]; numElements=0; backingArray=newArray; } public boolean equals(Object o){ if(o instanceof Set &&(((Set)o).size()==numElements)){ for(E elem:(Set<E>)o){ if (this.contains(o)==false){ return false; } return true; } } return false; } public boolean contains(Object o){ for(E backingElem:backingArray){ if (o!=null && o.equals(backingElem)){ return true; } } return false; } public boolean containsAll(Collection<?> c){ for(E elem:(Set<E>)c){ if(!(this.contains(elem))){ return false; } } return true; } public int hashCode(){ int sum=0; for(E elem:backingArray){ if(elem!=null){ sum=sum+elem.hashCode(); } } return sum; } public boolean isEmpty(){ if(numElements==0){ return true; } else{ return false; } } public boolean remove(Object o){ int i=0; for(Object elem:backingArray){ if(o!=null && o.equals(elem)){ backingArray[i]=null; numElements=numElements-1; E[] newArray=Arrays.copyOf(backingArray,backingArray.length-1); return true; } i=i+1; } return false; } public boolean removeAll(Collection<?> c){ for(Object elem:c){ this.remove(elem); } return true; } public boolean retainAll(Collection<?> c){ MySet<E> removalArray=new MySet<E>(); for(E arrayElem:backingArray){ if(arrayElem!= null && !(c.contains(arrayElem))){ this.remove(arrayElem); } } return false; } public int size(){ return numElements; } public <T> T[] toArray(T[] a) throws ArrayStoreException,NullPointerException{ for(int i=0;i<numElements;i++){ a[i]=(T)backingArray[i]; } for(int j=numElements;j<a.length;j++){ a[j]=null; } return a; } public Object[] toArray(){ Object[] newArray=new Object[numElements]; for(int i=0;i<numElements;i++){ newArray[i]=backingArray[i]; } return newArray; } public Iterator<E> iterator(){ setIterator iterator=new setIterator(); return iterator; } private class setIterator implements Iterator<E>{ private int currIndex; private E lastElement; public setIterator(){ currIndex=0; lastElement=null; } public boolean hasNext(){ while(currIndex<=numElements && backingArray[currIndex]==null){ currIndex=currIndex+1; } if (currIndex<=numElements){ return true; } return false; } public E next(){ E element=backingArray[currIndex]; currIndex=currIndex+1; lastElement=element; return element; } public void remove() throws UnsupportedOperationException,IllegalStateException{ if(lastElement!=null){ MySet.this.remove((Object)lastElement); numElements=numElements-1; } else{ throw new IllegalStateException(); } } } } I've been able to reduce the problems, but otherwise this thing is still causing problems.

• Is this a b43 driver problem?

  - by Nullet

  I have 13.04 on a Dell Inspiron 1564 with Broadcom 4312 WiFi card. The wl drivers cause kernel panic on linux-3.8 so I succesfully installed the b43 driver a couple of months ago. Now I have changed ISP and got a new router, and the connection drop when downloading software from internet to a 2008r2 using Remmina Client, and apt-get install on virtual machines in virtualbox. I have no idea why this suddenly became a problem.. My phone does not loose the connection, just Ubuntu. Output from /var/log/syslog after lost connection rfkill list(after disconnecting): 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes I can use NetworkManager to disable wireless and then enable wireless to connect again. rfkill ublock all/wifi/0 removes only Soft blocked. lshw -C network *-network description: Wireless interface physical id: 4 logical name: wlan0 serial: 78:e4:00:78:d2:05 capabilities: ethernet physical wireless configuration: broadcast=yes driver=b43 driverversion=3.8.0-32-generic firmware=478.104 ip=10.0.0.3 link=yes multicast=yes wireless=IEEE lspci 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) After waking from suspend and when booting, it takes about 40 sec to get network connection. This has been a problem all along AND a different question, but I mention it anyway.. cus it's annoying! Please take a look and hopefully someone spot a problem! Thanks!

• How do I get any number of links to space evenly? [migrated]

  - by Aerodynamo

  Alright, so here is the situation... Say I have a navbar for a site, and I allow users to change the number of links they want on this navbar. This means they could have 3, 5, 10, etc. What I want to do is make it so that if one link is up, it only takes up, say, 1/5th of the space on the navbar. If I weren't using borders, I might do something like: width: 18%; padding: 0 1%; However, I have two problems with this: 1) For 4 buttons, that's fine that it doesn't fill up the whole row. It would look ugly if the links were too wide... but when I have 6 or 7 buttons, it's got huge overflow! 2) Since I have borders, I can't use a percentage value for the borders or the widths, because I can't properly estimate how much of the percentage it will be. Now, I know I don't have to use percentage values, but what I would ideally prefer is that the first button is the smallest possible size necessary for all the other buttons to fit properly, meaning that if I have 950px and 6 links, the first link can be about 150px while the others are 160px... that's fine. I want all the other buttons on the navbar to be equally sized, regardless of how many links there are. I also need for it to accept a border... I figure the way to do this is to put a border in the nested div, so that way it doesn't effect the overall width of the button? This is all well and good, but I'm still plagued by the issue of not being able to design a dynamic site using the style I want if I can't get all the nav buttons to fit the width properly. Are there some js tricks I could use? I don't even know... Thanks

• Ubuntu is unresponsive and scrolling is very jerky

  - by peterpipe

  I'm new to Ubuntu. I've been using 12.04LTS for over a week now. For 3 days it was great but now I'm having a number of problems. I'm using an Acer Aspire one D255 it has a 250GB HDD and a 1GB Memory. My browser is Firefox. Pages freeze occasionally and I wait for over 10 minutes and have to use the computer's 'off' button. Pages crash. On facebook some pictures don't load and I have to close down and restart a couple of times. Scrolling can sometimes be very jerky. Downloading software has become a problem and I have a 'no entry' sign in the top taskbar. I've looked at this page for some help but the words used and the explanations are not helpful to someone like me who has little knowledge of this. Please - 'Ubuntu for dummies'. I'd like to continue using Ubuntu but am close to giving up.

• Why does Ubuntu 12.10 Beta2 insist on commiting changes to the partition table?

  - by Uten

  Why does Ubuntu 12.10 Beta2 insist on commiting changes to the partition table even as no real changes has been done? This is a show stopper for me as I'm installing without a CD/DVD ROM. This is how I go about it. I downloaded the iso image and extracted vmlinuz and initrd.lz to the same folder I keep the iso image. Configured grub (0.9x) to boot /ubuntu/vmlinuz with the iso image like this: title ubuntu live-cd kernel /ubuntu/vmlinuz boot=casper iso-scan/filename=/ubuntu/ubuntu-12.10-beta2-desktop-i386.iso ro quiet splash initrd /ubuntu/initrd.lz boot This works well and I get a running livecd session. The iso image is mounted on /isomedia (or something similar). The spare HD space where I want to install Ubuntu is in the logical area (at the wery end of the disk). I have tried both to use the space as empty and preformated with ext4. After selecting the partition and selecting "use as ext4" and selecting a mountpoint (/) I get the message: "The installer needs to commit changes to partition tables, but cannot do so because partitions on the following mount points could not be unmounted" "/isomedia" (or something similar). Is this a "feature" of the installer? To insist that everything is unmounted even if no changes is nescesary (as fare as I understand). It's probably a safety feature but is it needed? I have cahnged layouts with parted and gparted (at the end of the disk) for years without any failures. I understand that booting the iso image like this is not the common way. But it is just such a beautifull way of doing it when you hav a running system and want to play with another. Any one had any success installing Ubuntu (12.10 beta2 ) like this? Best regards Uten

• Working in Germany (Munich) [closed]

  - by adri

  My husband and I are relocating to Munich in August (He's German). I have been looking for jobs online since I heard that software developers are in great demand. And by the looks of it, seems to be correct. There are lots of offers on line but I have a problem, my german is not spectacular. I would rate it as basic. Good to be a tourist but not good to write anything formal, not even my cover letter. So I was wondering how hard is really going to be to find a job for me with virtually no german (I'm studying, but good german is not going to happen over night). Also, would it be possible to secure a job before arriving to Germany? I have nearly 10 years of working experience developing software, mostly in .net (c#, vb, winForms, asp.net) but I also know java. 3 years experience as a team leader for groups of up to 8 people. In the last couple of years I've been working mostly on digitalization of documents (such as birth certificates and the like) but I'm more than willing to try other fields Also I speak English, Spanish, Italian, a bit of portuguese and of course a bit of german.

• In facebook pictures bdon't always load properly and scrolling is very jerky

  - by peterpipe

  I'm new to Ubuntu. I've been using 12.04LTS for over a week now. For 3 days it was great but now I'm having a number of problems. I'm using an Acer Aspire one D255 it has a 250GB HDD and a 1GB Memory. My browser is Firefox. Pages freeze occasionally and I wait for over 10 minutes and have to use the computer's 'off' button. Pages crash. On facebook some pictures don't load and I have to close down and restart a couple of times. Scrolling can sometimes be very jerky. Downloading software has become a problem and I have a 'no entry' sign in the top taskbar. I've looked at this page for some help but the words used and the explanations are not helpful to someone like me who has little knowledge of this. Please - 'Ubuntu for dummies'. I'd like to continue using Ubuntu but am close to giving up.

• Arguments for discouraging satellite sites?

  - by Jjdelc

  I am working with a client who's read about satellite sites on a SEP book and has been building hundreds of keyword reach domains (buytoyotacorona1989cheap.com, brandnewsuvinred.com) with specific content about such domains. They all link to a main domain (CompanyName.com) where most of the information is either repeated(from other sites) or new. I told him to drop all the other domains and only focus on building good content for the main site as it is too difficult to maintain so many websites, plus they might look like link farms to Google. He told me to make a Google search for "Buy Toyota cheap " and two of his websites were listed among top 10. So it's seem to be doing some good, but I get the feeling that what he is doing is wrong. What other arguments are there to discourage this practice? or is he doing the right thing? My arguments have helped him to decide go down from hundreds to close to one hundred (because cost of maintainance) but I believe he should only have one or two sites. PS: The business is not actually about cars.

• c++ accumulate with move instead of copy [migrated]

  - by user74399

  I have the following code auto adder = [](string& s1, const string& s2)->string&& { if (!s1.empty()) s1 += " "; s1 += s2; return move(s1); }; string test; test.reserve(wordArray.size() * 10); string words = accumulate(wordArray.begin(), wordArray.end(), move(test), adder); What I would like here is to avoid string copying. Unfortunately this is not accomplished by the vs2012 implementation of accumulate. Internally accumulate calls another function _Accumulate and the rvalue functionality gets lost in the process. It I instead call the _Accumulate function like so string words = Accumulate(wordArray.begin(), wordArray.end(), move(test), adder); I get the intended performance gain. Must the std library be rewritten to take rvalue arguments into consideration? Is there some other way I may use accumulate to accomplish what I want without cheating to much?
