• 12.04 Booting into Terminal

  - by user170796

  To preface this, I would like to say that I am completely new to Ubuntu and have essentially zero programming experience/experience working with command line and terminal. I installed Ubuntu because I would like to get into programming. If you could provide me with the simplest instructions possible, I would be grateful. I have a Lenovo Ideapad Y500 (Intel i7, NVidia GT 750m, 1TB HDD, 16GB SSD cache, 8GB RAM) with Windows 8 on it. Using a Live CD, I installed Ubuntu 12.04 onto a 75 GB partition. During the installation, I kept all default settings except for one thing; I decided to encrypt my home folder, and so checked the corresponding box. The installation completed, and I restarted. Once I restarted, I saw the options "Ubuntu, with Linux 3.2.0-23-generic" "Ubuntu, with Linux 3.2.0-23-generic (recovery mode)" "Memory test (memtest86+)" "Memory test (memtest86+, serial console 115200)" "Windows Recovery Environment (loader) (on /dev/sdb3)" "Windows 8 (loader) (on /dev/sdb5)" "System Setup" I chose the first option, and was directed to a screen with the Ubuntu logo and the row of five dots below that change from orange to white. Then, I was brought to a full screen terminal that prompted me to login, which I did. I saw no option to boot into GUI at all, and am lost. I've been searching around and have tried the "startx" command to no avail. Should the command have some sort of context or something? I've also tried selecting the recovery mode option from the boot manager. I've tried the resume option from the following menu, which eventually just shuts down the computer after displaying a lot of scrolling text that's too fast for me to read. I've also tried the failsafex mode from the recovery mode menu, which only brings up a terminal box at the bottom of the window that covers the entire bottom part of the screen. Commands won't work in this window. When I try to access Windows 8, I get a message saying that the EFI file path was not specified or something along those lines. I had to enable Secure Boot in order to access Windows 8 (I had disabled it to be able to boot from the Live CD), which is functioning normally. I am at a complete loss for what to do. Any help will be extremely appreciated. EDIT: Bonus question! If you could figure out a way for me to boot to Windows 8 without having to enable Secure Boot, it would save me a lot of trouble. I can deal with switching every time, but I'd rather not have to.

• What happens to the storage capacity when I uninstall Ubuntu?

  - by shole1202

  I used the wubi installer for Ubuntu 12.04. After having trouble with getting the Operating System to boot, I tried uninstalling it with wubi. From 'My Computer' (in Windows 7), I noticed the maximum capacity of my hard drive drop from 256gb to 238gb. I have tried using some methods with the command prompt to locate the missing storage, but Windows now only recognizes that the storage on the disk to have 238gb instead of the original 256. Is there any way to recover that memory?

• Should we persist with an employee still writing bad code after many years?

  - by user94986

  I've been assigned the task of managing developers for a well-established company. They have a single developer who specialises in all their C++ coding (since forever), but the quality of the work is abysmal. Code reviews and testing have revealed many problems, one of the worst being memory leaks. The developer has never tested his code for leaks, and I discovered that the applications could leak many MBs with only a minute of use. User's were reporting huge slowdowns, and his take was, "it's nothing to do with me - if they quit and restart, it's all good again." I've given him tools to detect and trace the leaks, and sat down with him for many hours to demonstrate how the tools are used, where the problems occur, and what to do to fix them. We're 6 months down the track, and I assigned him to write a new module. I reviewed it before it was integrated into our larger code base, and was dismayed to discover the same bad coding as before. The part that I find incomprehensible is that some of the coding is worse than amateurish. For example, he wanted a class (Foo) that could populate an object of another class (Bar). He decided that Foo would hold a reference to Bar, e.g.: class Foo { public: Foo(Bar& bar) : m_bar(bar) {} private: Bar& m_bar; }; But (for other reasons) he also needed a default constructor for Foo and, rather than question his initial design, he wrote this gem: Foo::Foo() : m_bar(*(new Bar)) {} So every time the default constructor is called, a Bar is leaked. To make matters worse, Foo allocates memory from the heap for 2 other objects, but he didn't write a destructor or copy constructor. So every allocation of Foo actually leaks 3 different objects, and you can imagine what happened when a Foo was copied. And - it only gets better - he repeated the same pattern on three other classes, so it isn't a one-off slip. The whole concept is wrong on so many levels. I would feel more understanding if this came from a total novice. But this guy has been doing this for many years and has had very focussed training and advice over the past few months. I realise he has been working without mentoring or peer reviews most of that time, but I'm beginning to feel he can't change. So my question is, would you persist with someone who is writing such obviously bad code?

• Greenspun's Tenth Rule, does every large project include a Lisp interpreter?

  - by casualcoder

  Greenspun's tenth rule (actually the only rule) states that: Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp. My memory is that there are some papers on the topic, perhaps for Borland's Quattro (spreadsheet) project and possibly others. Google is unhelpful, maybe the right search terms are not coming to mind. I am looking for papers or articles supporting this claim, if any.

• What class to use in order to have a number move around the screen?

  - by AllenZ41

  What i am trying to accomplish is have a randomly created number move around the screen but it is touchable. I am planning to have lots of numbers on the screen, so my question is what class is appropriate to use, so I could set a number randomly at run time and display it while it moves around the screen? I was planning the use a TextView, since I want to use a custom font of mine but I think creating a bunch at a time could cause a memory problem and to my understanding they cant move around the screen at runtime.

• Which Android phone to use for development...?

  - by Nikos

  Hi, I'm planning to port a couple of games from iPhone/Windows Mobile to the Android platform. The games are written in C++ so I plan to use the NDK with a thin java wrapper. I'm new to the Android platform and need some advice on which phone to buy for development. I suspect like Windows Mobile there is a level of fragmentation with different phones supporting different features (keyboard/ rotation/ screen size/ capacitive touch screen/ etc). What are the best device(s) for development on the Android platform...? They also have to be available in the UK/Europe. Thank you in advance. Nikos.

• How to debug packet loss ?

  - by Gene Vincent

  I wrote a C++ application (running on Linux) that serves an RTP stream of about 400 kbps. To most destinations this works fine, but some destinations expericence packet loss. The problematic destinations seem to have a slower connection in common, but it should be plenty fast enough for the stream I'm sending. Since these destinations are able to receive similar RTP streams for other applications without packet loss, my application might be at fault. I already verified a few things: - in a tcpdump, I see all RTP packets going out on the sending machine - there is a UDP send buffer in place (I tried sizes between 64KB and 300KB) - the RTP packets mostly stay below 1400 bytes to avoid fragmentation What can a sending application do to minimize the possibility of packet loss and what would be the best way to debug such a situation ?

• google spreadsheet api from android: google-api-java-client or handmade?

  - by yetanothercoderu

  For working with google spreadsheet api from android (2.2) - google suggests using google-api-java-client for android. For that you have to include 5 jars to your android application: guava-r09.jar google-http-client-extensions-android2-1.6.0-beta.jar google-api-client-extensions-android2-1.6.0-beta.jar google-http-client-1.6.0-beta.jar google-api-client-1.6.0-beta.jar and digging into google-api-java-client javadocs for fast-changing api. Does it worth the effort? in term of android specifics and device fragmentation? Isn't it reasonable to write your own simple http response parser or take small existing library like google-spreadsheet-lib-android ? Thanks! UPD: choosed google-api-java-client finally as it has all routine stuff (like parsing http, xml) out of box

• C# socket blocking behavior

  - by Gearoid Murphy

  My situation is this : I have a C# tcp socket through which I receive structured messages consisting of a 3 byte header and a variable size payload. The tcp data is routed through a network of tunnels and is occasionally susceptible to fragmentation. The solution to this is to perform a blocking read of 3 bytes for the header and a blocking read of N bytes for the variable size payload (the value of N is in the header). The problem I'm experiencing is that occasionally, the blocking receive operation returns a partial packet. That is, it reads a volume of bytes less than the number I explicitly set in the receive call. After some debugging, it appears that the number of bytes it returns is equal to the number of bytes in the Available property of the socket before the receive op. This behavior is contrary to my expectation. If the socket is blocking and I explicitly set the number of bytes to receive, shouldn't the socket block until it recv's those bytes?, any help, pointers, etc would be much appreciated.

• MySQL: Efficient Blobbing?

  - by feklee

  I'm dealing with blobs of up to - I estimate - about 100 kilo bytes in size. The data is compressed already. Storage engine: InnoDB on MySQL 5.1 Frontend: PHP (Symfony with Propel ORM) Some questions: I've read somewhere that it's not good to update blobs, because it leads to reallocation, fragmentation, and thus bad performance. Is that true? Any reference on this? Initially the blobs get constructed by appending data chunks. Each chunk is up to 16 kilo bytes in size. Is it more efficient to use a separate chunk table instead, for example with fields as below? parent_id, position, chunk Then, to get the entire blob, one would do something like: SELECT GROUP_CONCAT(chunk ORDER BY position) FROM chunks WHERE parent_id = 187 The result would be used in a PHP script. Is there any difference between the types of blobs, aside from the size needed for meta data, which should be negligible.

• Call Contact list on non-standard Android phones

  - by sgarman

  I am creating a widget that you can assign a contact to onClick. I used the method that is described here. This works great on standard Android phones such as the Motorola Droid, HTC Nexus One and HTC G1. The problem is for users who are using devices such as the HTC Incredible or HTC Droid Eris (Both running Sense UI) and I imagine on other phones who's OS deviates from the vanilla flavor of Android. Using my current method I thought that the device's OS would hook into whatever that manufacture chose to use for their Contact system however users are being sent to a random list of numbers, not their Contact list. Does anyone have a suggestion on how to get those Contacts or is this just another example of the Android fragmentation issue? Any help or insight is greatly appreciated.

• When will a TCP network packet be fragmented at the application layer?

  - by zooropa

  When will a TCP packet be fragmented at the application layer? When a TCP packet is sent from an application, will the recipient at the application layer ever receive the packet in two or more packets? If so, what conditions cause the packet to be divided. It seems like a packet won't be fragmented until it reaches the Ethernet (at the network layer) limit of 1500 bytes. But, that fragmentation will be transparent to the recipient at the application layer since the network layer will reassemble the fragments before sending the packet up to the next layer, right?
