How to get a Toshiba L505 to boot USB or CD

- by ShroudedCloud

OK, have a Toshiba L505 (not sure of the extended model number) that got a virus on Windows and will no longer will boot into that, so I'm trying to revive it with Ubuntu. Problem is, when I tell it to boot into a USB image of 12.04 32- or 64-bit, 13.04 64-bit, or elementary Luna 32-bit, it gives me some screen with a copyright from 2000 for Intel, invariably spits out a "media not recognized" type of error and then says PXE-ROM exiting. Well, that's annoying. So I went in with a CD (12.04 x86_64 having tried 32-bit in the past as well). Boot menu, select, starts running. Seeing the loading screen for Ubuntu, going well... until it's not. Again, invariably, it fails. The CD drive will cease spinning at around the same time each time and then the laptop will stop doing everything altogether (at least, everything spins down and it goes quiet). As far as I can tell, it's not to do with what function is being loaded from the CD at the time (because that bit is variable). I'd love to be able to boot from USB (since it will be all but required going forward), but getting the CD to work would be wondrous too. Anyone have any ideas of where I can go from here to try to fix this? My friends and I have turned up nothing.

Static IP Address on Ubuntu 12.04 Virtual Machine

- by chrisnankervis

I've setup a VM running Ubuntu 12.04 specifically for local web development and am having some problems ensuring it has a static IP address. A static IP address is important as I'm using the IP address in my hosts file to assign a .local suffix to addresses used both in browser and to connect to the correct database on the VM. Currently, every time I connect to a new network or my VM is assigned a new IP address I need to reconfigure my whole environment which is becoming quite a pain. It also probably doesn't help that the default-lease-time on the Ubuntu VM is set to 1800 by default. At the moment I'm using VMWare Fusion and the Network Adapter is enabled and set to "Autodetect" under Bridged Networking. I've tried to set a static IP address within the dhcpd.conf using the code below: host ubuntu { hardware ethernet 00:50:56:35:0f:f1; fixed-address: 192.168.100.100; } The fixed-address that I've used is also outside the range specified in the subnet block (which in this case is 192.168.100.128 to 192.168.100.254). I've tried adding and removing the network adapter and restarting my Mac after each time to no avail. Below is an ifconfig of the VM that might be of some help: eth0 Link encap:Ethernet HWaddr 00:50:56:35:0f:f1 inet addr:192.168.0.25 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::250:56ff:fe35:ff1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1624 errors:0 dropped:0 overruns:0 frame:0 TX packets:416 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:147348 (147.3 KB) TX bytes:41756 (41.7 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Are there any specific issues with 12.04 that I'm missing? Otherwise has anyone else got any ideas? Thanks in advance.

Font corruption: lines through characters

- by Aibara Iduas

I have an odd problem where a one-pixel high white line is displayed through certain letters of text. Almost always only a single character type is affected at once, and only in one font size (though that size can change over time). Most of the time things are fine, but this happens several times a day. It's been happening ever since I upgraded to 10.10. I have noticed few patterns: It might be a problem with Firefox (I'm currently using the nightly ppa, but it occurred in 3.6 also) - but this could just be because I spend most of my time on my computer either at a browser or text editors. I seem to remember it happening with the buttons on various Gnome dialogs. It never occurs in text I've typed, be it an email, url bar, etc. In Firefox it happens across tabs, and the problem remains even if they are closed or reloaded; only restarting the program can fix it. Two examples (in the first, only the larger "r" is corrupted): Any help would be appreciated, thanks.

Frustrated with MythTV 0.26

- by Mike

I've been using MythTV for a while now. Until a hardware crash I had a 0.25 box running without problems. Had to get new hardware and am now in the process of setting up 0.26. Every time I pick a menu option, it hangs for 1 minute. Every time I try to start the backend, same thing. I pick a new theme in the frontend, but it never gets used. I try to test audio, but all I get is static (from the proper channels though). I've setup the storage groups in the backend and put a video in /storage/videos but the front end won't see it when I scan for changes. I make changes in the front end configuration and they don't get saved (or get lost randomly 2-3 reloads later). Obviously there is something I am doing catastrophically wrong, but I have no idea what. Are the storage groups not working yet? Maybe I need to delete all the storage group entries and just use the front end override to set the path? I'm currently using lvm across 3 hard disks, and this has worked well for me in the past. I'd like to use storage groups, but frankly I don't see them working yet at all - especially not for videos (which is what we watch 99% of the time). Anyone have any suggestions for me to try before I just call 0.26 bad names and wipe the system?

PowerShell a constant in a changing world

- by Rob Addis

I've been programming for about 20 years now some of my friends have been at it for over 30. I have read many, many manuals and yes it's not my favourite past time. So 10 years ago I made a promise to myself to try and only learn about products which have long life times. I immediately gave up programming GUIs and concentrated on back end development as I decided that these products (Oracle, MQ Series, SQL Server, BizTalk and later WCF, WF) have longer life times and smaller incremental changes than front end products.10 years ago I had no idea how good a decision that would turn out to be. There have been so many different Microsoft products for the front end in that time; multiple versions of Windows Forms, FrontPage, Html, Javascript, ASP.net, Silverlight, SharePoint, WPF and now hopefully a stayer Metro.I remember being at a Microsoft conference in 2006 when Martin Fowler told a crowd of developers (I'm paraphrasing) "If you don't like change then you're in the wrong business!". Well I've been in the business for 20 years and yes I'm a little resistant to change. I like my investment in reading manuals and getting certified to be time well spent!Over the last 2 years I have been writing A LOT of PowerShell script, I think there is a good chance this product will still be around and be used for new development in 10 years, learning it is a good investment.

Live programming help

- by frazras

This idea has been floating around my head for a few years. I started some work on it but I just want to know if it is feasible, sensible, or if there is something else like it out there. Dont want to know I was wasting time on a solved issue. Whenever I have a programming issue, this is my sequence: Google it!: That usually brings up a lot of things: blogs, forums, stackoverflow, stackexchange, and even the official docs of the language/framework/cms. Ask on IRC: I format my question and try to get people on IRC to help me. Make a post: I create a post on forums/stackoverflow/stackexchange or shout on twitter with hashtags. Now a lot of the time I am in the middle of a project with a deadline. So I want answers NOW!!! Sometimes just 5-15 minutes worth of attention. Usually by the time I am failing at getting answers at #2, I am imagining how many people are ONLINE NOW with the skill and my exact answer but playing video games, watching youtube or idling online. However, if they were motivated, they would invest the 15 mintes helping me, that would make a world of a difference. I am even in positions where I would PAY for that 15 minutes of instant help. If your rate is as much as $100/hour (relatively good programmer) that is $25 that might save me 3 hours. This help would be live, text chat/skype/phone/screenshare. Should I continue developing this idea or is there a better alternative out there? Or is this even an unfeasible idea?

AdvanceTimePolicy and Point Event Streams In StreamInsight.

There are a number of ways to issues CTIs (Current Time Increments) into your StreamInsight streams but a quite useful way is to do it declaratively on your source factory like this public AdapterAdvanceTimeSettings DeclareAdvanceTimeProperties<TPayload>(InputConfig configInfo, EventShape eventShape) { return new AdapterAdvanceTimeSettings( new AdvanceTimeGenerationSettings(configInfo.CtiFrequency, TimeSpan.FromTicks(-1)), AdvanceTimePolicy.Adjust); } This will issue a CTI after every event and allows no delay (for delayed events) by stamping the CTI with the timestamp of the last event minus 1 tick. The very last statement "AdvanceTimePolicy.Adjust" tells the adapter what to do with events that violate the policy (arrive late). From BOL "Events that violate the inserted CTI are moved in time if their lifetime overlaps with the CTI timestamp. That is, the start timestamp of the events is set to the most recent CTI timestamp, which renders those events valid. If both start and end time of an event fall before the CTI timestamp, then the event is dropped." This means that if you are using this method of inserting CTIs for a Point event stream and have specified "AdvanceTimePolicy.Adjust" for the violation policy, this setting will be ignored and instead it will use "AdvanceTimePolicy.Drop" because a Point event can never straddle a CTI.

Business Intelligence (BI) Defined

CIO.com defines Business Intelligence (BI) as a generic reference to a collection of applications that are used to analyze raw organizational data. Typical BI activities include data mining, online analytical processing, querying and reporting. They further explain that the primary reason why a company would utilize BI is to make their more data accessible. The more accessible data is to the users the faster they can identify ways to reduce business cost, discover new business opportunities, and react quickly to adjust prices based on current supply and demand. One area in which a hospital system could use BI derived from a data warehouse can be seen in the Emergency Room (ER) in regards to the number of doctors and nurse they have working during a full moon for each ER location. In order determine this BI needs to determine a trend in the number of patients seen on a full moon, further more they also need to determine the optimal number of staff members working during a full moon be determining the number of employees to patients ration needed to meet standard patient times and also be the most cost effective for the hospital. This will allow the hospital system to estimate the number of potential patients they will have on the next full moon and adjust their staff schedules accordingly to ensure that patient care is not affected in any way do the influx or lack of influx of patients during this time while also ensuring that they are only working the minimum number of employees to ensure that they still making a profit. Another area where a hospital system could use BI data regards their orders paced to drug and medical supply companies. BI could define trends in prescriptions given to patients, this information could be used for ordering new supplies and forecasting the amount of medicine each hospital needs to keep on site at a given time. For example, a hospital might want to stock up on materials need to set bones in a cast prior to the summer because their BI indicates that a majority of broken bones occur during the summer due to children being out of school and they have more free time.

A terminal emulator for ex-Windows users

- by Dan

There are several things I would like to be better in Ubuntu Terminal Emulator. coloring, like in the source code Copy and paste keyboard shortcuts that I used all the time in Windows: Ctrl-C and Ctrl-V (Most of people here in Ubuntu use Ctrl+C and Ctrl+V keyboard shortcuts to copy and paste everywhere except the terminal! I think it's annoying for newcomers, and I don't worry about historical reasons) A feature to save all the output to log file UPDATE: Can the terminal be a powerful feature-full user-friendly tool like a modern IDE? The Linux user can spend 30% of time in the terminal. Programmers no longer code in a notepad. Can I see the history pane? Suggestions? Directory pane? Commands list? Search for words in an output? Contextual behavior? "Search in Google" for a mouse right-click. Tips and tricks learning? Time is money! Please, people, give me a link to the 21st - century terminal.

Really slow wireless internet on 12.04 with HP dv6 6070ca

- by Joe

I was recently running the previous version of Ubuntu through Wine, and everything was working great. I decided to upgrade to pangolin when I saw it came out. After upgrading the internet was very slow (the estimated time on the updates was something like 4 days). I thought maybe this had something to do with the Wine installation, so I decided to finally do an actual dual boot. I partitioned my drive all nice and neat, but I made the mistake of connecting to the internet for the installation, and clicking the option to install updates and restricted extras. This was in the morning, circa 6 am. Fast forward to the evening, the installation is frozen at around 75%. In frustration I gave the ol girl a hard shut-down, which effectively rendered my machine useless. I used the thumb drive to reinstall Ubuntu, this time without connecting to the internet. Installed nice and easy, no problems, but the internet is still ridiculously slow. It took me about 20 minutes of frustration and hitting stop and reload repeatedly to even get this question page to open. This is important to me as now Windows won't even boot and I have to use ubuntu for the time being but I can't even bear to turn on my laptop due to the frustration that immediately ensues. Please help! Oh, and I'm relatively new so if there are some terminal commands that spew out info you guys would find useful let me know what they are and I'll post back the information.

Pros and Cons between learning to program on Windows and Linux and Macs

- by Amumu

I have been studying IT for 2 years and I'm going to graduate soon in this year (if everything goes well). I think it's time for me to choose a path to specialized into some fields of this large industry. Personally, I want to be a game programmer. But to be a game programmer, surely I have to invest my time to study Windows Programming, then DirectX and other programming techniques related to game. On the other hand, Linux seems promising as well. I am not sure about Game Programming on for it, but it seems become an expert for this OS, and by expert it's not about using the OS to become an administrator, but can do further than that, such as understand the OS to its essence and can produce applications for it. However, there's some obstacles in my view for this development path. Many of my friends think that Linux is based on free and open source, and if you follow it, as its name suggested: Free and Open Source, it means we also give away our software free. Otherwise, we will have to find a second job to make living. Currently, I think a viable way to make money on Linux is doing works related to client-server. Another way to developer my career is to become expert in developing business applications for companies. This is more on business, not on specialized IT fields so I am not really interested. Another alternative is programming on mobile devices, such as iPhone, Android and it seems very promising and easier to approach. Another way is to become a computer scientist and research on academic subjects such as AI, human-computer interaction, but this is far beyond my reach, so I won't invest my time on it until I feel I am experienced enough. That's all I can think of for now. I may miss a lot of things, so I need more opinions as input to get the big picture of the industry for my career path.

I could use some help with my SQL command

- by SuperSpy

I've got a database table called 'mesg' with the following structure: receiver_id | sender_id | message | timestamp | read Example: 2 *(«me)* | 6 *(«nice girl)* | 'I like you, more than ghoti' | yearsago | 1 *(«seen it)* 2 *(«me)* | 6 *(«nice girl)* | 'I like you, more than fish' | now | 1 *(«seen it)* 6 *(«nice girl)* | 2 *(«me)* | 'Hey, wanna go fish?' | yearsago+1sec | 0 *(«she hasn't seen it)* It's quite a tricky thing that I want to achieve. I want to get: the most recent message(=ORDER BY time DESC) + 'contact name' + time for each 'conversation'. Contact name = uname WHERE uid = 'contact ID' (the username is in another table) Contact ID = if(sessionID*(«me)*=sender_id){receiver_id}else{sender_id} Conversation is me = receiver OR me = sender For example: From: **Bas Kreuntjes** *(« The message from bas is the most recent)* Hey $py, How are you doing... From: **Sophie Naarden** *(« Second recent)* Well hello, would you like to buy my spam? ... *(«I'll work on that later >p)* To: **Melanie van Deijk** *(« My message to Melanie is 3th)* And? Did you kiss him? ... That is a rough output. QUESTION: Could someone please help me setup a good SQL command. This will be the while loup <?php $sql = "????"; $result = mysql_query($sql); while($fetch = mysql_fetch_assoc($result)){ ?> <div class="message-block"> <h1><?php echo($fetch['uname']); ?></h1> <p><?php echo($fetch['message']); ?></p> <p><?php echo($fetch['time']); ?></p> </div> <?php } ?> I hope my explanation is good enough, if not, please tell me. Please don't mind my English, and the Dutch names (I am Dutch myself) Feel free to correct my English UPDATE1: Best I've got until now: But I do not want more than one conversation to show up... u=user table m=message table SELECT u.uname, m.message, m.receiver_uid, m.sender_uid, m.time FROM m, u WHERE (m.receiver_uid = '$myID' AND u.uid = m.sender_uid) OR (m.sender_uid = '$myID' AND u.uid = m.receiver_uid) ORDER BY time DESC;

Failed Project: When to call it?

- by Dan Ray

A few months ago my company found itself with its hands around a white-hot emergency of a project, and my entire team of six pulled basically a five week "crunch week". In the 48 hours before go-live, I worked 41 of them, two back to back all-nighters. Deep in the middle of that, I posted what has been my most successful question to date. During all that time there was never any talk of "failure". It was always "get it done, regardless of the pain." Now that the thing is over and we as an organization have had some time to sit back and take stock of what we learned, one question has occurred to me. I can't say I've ever taken part in a project that I'd say had "failed". Plenty that were late or over budget, some disastrously so, but I've always ended up delivering SOMETHING. Yet I hear about "failed IT projects" all the time. I'm wondering about people's experience with that. What were the parameters that defined "failure"? What was the context? In our case, we are a software shop with external clients. Does a project that's internal to a large corporation have more space to "fail"? When do you make that call? What happens when you do? I'm not at all convinced that doing what we did is a smart business move. It wasn't my call (I'm just a code monkey) but I'm wondering if it might have been better to cut our losses, say we're not delivering, and move on. I don't just say that due to the sting of the long hours--the company royally lost its shirt on the project, plus the intangible costs to the company in terms of employee morale and loyalty were large. Factor that against the PR hit of failing to deliver a high profile project like this one was... and I don't know what the right answer is.

Need to run a .sh as root on boot or login

- by Graymayre

Still new with linux and running ubuntu 12.10 I have a wireless stick (ae2500) which has known issues that has been partially solved using ndiswrapper. However, to use it I must run the same scripts every time I reboot, effectively uninstalling and reinstalling the driver. I made a .sh file to run every time to make it easy, but I must do the sudo login everytime. There are three solutions I am looking for and although not all are necessary to solve this particular problem, I would still like to know them all for learning purposes. run scripts or file.sh on boot (as well as other programs) run scripts or file.sh automatically with root privileges make the install permanent so as not to have to go through the process every time. Any additional information that can help me regarding this that I did not think to ask (including streamlining my commands), or general knowledge, would be greatly appreciated. Following are the contents of the file. I pretty much just made it as I would have entered it. cd ~/ndiswrapper-1.58rc1 sudo modprobe -rf ndiswrapper sudo rm /etc/modprobe.d/ndiswrapper.conf sudo rm -r /etc/ndiswrapper/* sudo depmod -a sudo make uninstall sudo make sudo make install sudo ndiswrapper -i bcmwlhigh5.inf ndiswrapper -l sudo modprobe ndiswrapper

How can I iterate over a collection of objects returned by a LINQ-to-XML query?

I've got this XML: <BillingLog> <BillingItem> <date-and-time>2003-11-04</date-and-time> <application-name>Billing Service</application-name> <severity>Warning</severity> <process-id>123</process-id> <description>Timed out on a connection</description> <detail>Timed out after three retries.</detail> </BillingItem> <BillingItem> <date-and-time>2010-05-15</date-and-time> <application-name>Callback Service</application-name> <severity>Error</severity> <process-id>456</process-id> <description>Unable to process callback</description> <detail>Reconciliation timed out after two retries.</detail> </BillingItem> </BillingLog> That I want to project using LINQ-to-XML into a collection of BillingItem objects contained in a single BillingLog object. public class BillingLog { public IEnumerable<BillingItem> items { get; set; } } public class BillingItem { public string Date { get; set; } public string ApplicationName { get; set; } public string Severity { get; set; } public int ProcessId { get; set; } public string Description { get; set; } public string Detail { get; set;} } This is the LINQ query that I'm using to project the XML (which is contained in the string variable source). XDocument xdoc = XDocument.Parse(source); var log = from i in xdoc.Elements("BillingLog") select new BillingLog { items = from j in i.Descendants("BillingItem") select new BillingItem { Date = (string)j.Element("date-and-time"), ApplicationName = (string)j.Element("application-name"), Severity = (string)j.Element("severity"), ProcessId = (int)j.Element("process-id"), Description = (string)j.Element("description"), Detail = (string)j.Element("detail") } }; When I try and iterate over the objects in log using foreach. foreach (BillingItem item in log) { Console.WriteLine ("{0} | {1} | {2} | {3} | {4} | {5}", item.Date, item.ApplicationName, item.Severity, item.ProcessId.ToString(), item.Description, item.Detail); } I get the following error message from LINQPad. Cannot convert type 'UserQuery.BillingLog' to 'UserQuery.BillingItem' Thanks in advance.

UNESCO, J-ISIS, and the JavaFX 2.2 WebView

- by Geertjan

J-ISIS, which is the newly developed Java version of the UNESCO generalized information storage and retrieval system for bibliographic information, continues to be under heavy development and code refactoring in its open source repository. Read more about J-ISIS and its NetBeans Platform basis here. Soon a new version will be available for testing and it would be cool to see the application in action at that time. Currently, it looks as follows, though note that the menu bar is under development and many menus you see there will be replaced or removed soon: About one aspect of the application, the browser, which you can see above, Jean-Claude Dauphin, its project lead, wrote me the following: The DJ-Native Swing JWebBrowser has been a nice solution for getting a Java Web Browser for most popular platforms. But the Java integration has always produced from time to time some strange behavior (like losing the focus on the other components after clicking on the Browser window, overlapping of windows, etc.), most probably because of mixing heavyweight and lightweight components and also because of our incompetency in solving the issues. Thus, recently we changed for the JavaFX 2.2 WebWiew. The integration with Java is fine and we have got rid of all the DJ-Native Swing problems. However, we have lost some features which were given for free with the native browsers such as downloading resources in different formats and opening them in the right application. This is a pretty cool step forward, i.e., the JavaFX integration. It also confirms for me something I've heard other people saying too: the JavaFX WebView component is a perfect low threshold entry point for Swing developers feeling their way into the world of JavaFX.

Transition from 2D to 3D Game development [closed]

- by jakebird451

I have been working in the 2D world for a long time from manual blitting in windows to SDL to Python (pygame, pyopengl) and a bunch in between. Needless to say I have been programming for a while. So a while ago I started to program in OpenGL via C++ on my Mac. I then got a little intricate with my work after a while (3D models with skeleton structure and terrain development). After a long time of tinkering, I stopped due to the heavy work just to yield a low level understanding of how OpenGL works. Still interested in Graphics and Game Development I went on a search for a stable game engine with some features to grow on. Licence Requirement: Anything other than GPL (LGPL will do) OS Requirement: Mac & Windows Shader: GLSL or CG (GLSL preferred due to experience) Models: Any model structure with rigging (bone) support & animation I am looking at http://www.ogre3d.org/ currently and am starting to meddle around with some examples. However I am a little reluctant to spend a lot of time on it only to yield another dead end. So instead of falling down a spiraling black pit, I am posting my question to you guys to lead me in the right direction based on my requirements. How was your experience with the engine you recommend? Is it well documented? Does it have well documented examples? Any library requirements (Boost, libpng, etc)?

Mocking concrete class - Not recommended

- by Mik378

I've just read an excerpt of "Growing Object-Oriented Software" book which explains some reasons why mocking concrete class is not recommended. Here some sample code of a unit-test for the MusicCentre class: public class MusicCentreTest { @Test public void startsCdPlayerAtTimeRequested() { final MutableTime scheduledTime = new MutableTime(); CdPlayer player = new CdPlayer() { @Override public void scheduleToStartAt(Time startTime) { scheduledTime.set(startTime); } } MusicCentre centre = new MusicCentre(player); centre.startMediaAt(LATER); assertEquals(LATER, scheduledTime.get()); } } And his first explanation: The problem with this approach is that it leaves the relationship between the objects implicit. I hope we've made clear by now that the intention of Test-Driven Development with Mock Objects is to discover relationships between objects. If I subclass, there's nothing in the domain code to make such a relationship visible, just methods on an object. This makes it harder to see if the service that supports this relationship might be relevant elsewhere and I'll have to do the analysis again next time I work with the class. I can't figure out exactly what he means when he says: This makes it harder to see if the service that supports this relationship might be relevant elsewhere and I'll have to do the analysis again next time I work with the class. I understand that the service corresponds to MusicCentre's method called startMediaAt. What does he mean by "elsewhere"?

Matlab cell length

- by AP

Ok I seem to have got the most of the problem solved, I just need an expert eye to pick my error as I am stuck. I have a file of length [125 X 27] and I want to convert it to a file of length [144 x 27]. Now, I want to replace the missing files (time stamps) rows of zeros. (ideally its a 10 min daily average thus should have file length of 144) Here is the code I am using: fid = fopen('test.csv', 'rt'); data = textscan(fid, ['%s' repmat('%f',1,27)], 'HeaderLines', 1, 'Delimiter', ','); fclose(fid); %//Make time a datenum of the first column time = datenum(data{1} , 'mm/dd/yyyy HH:MM') %//Find the difference in minutes from each row timeDiff = round(diff(datenum(time)*(24*60))) %//the rest of the data data = cell2mat(data(2:28)); newdata=zeros(144,27); for n=1:length(timeDiff) if timeDiff(n)==10 newdata(n,:)=data(n,:); newdata(n+1,:)=data(n+1,:); else p=timeDiff(n)/10 n=n+p; end end Can somebody please help me to find the error inside my for loop. My output file seems to miss few timestamped values. %*********************************************************************************************************** Can somebody help me to figure out the uiget to read the above file?? i am replacing fid = fopen('test.csv', 'rt'); data = textscan(fid, ['%s' repmat('%f',1,27)], 'HeaderLines', 1, 'Delimiter', ','); fclose(fid); With [c,pathc]=uigetfile({'*.txt'},'Select the file','C:\data'); file=[pathc c]; file= textscan(c, ['%s' repmat('%f',1,27)], 'HeaderLines', 1, 'Delimiter', ','); And its not working % NEW ADDITION to old question p = 1; %index into destination for n = 1:length(timeDiff) % if timeDiff(n) == 10 % newfile(p,:) = file(n,:); % newfile(p+1,:)=file(n+1,:); % p = p + 1; % else % p = p + (timeDiff(n)/10); % end q=cumsum(timeDiff(n)/10); if q==1 newfile(p,:)=file(n,:); p=p+1; else p = p + (timeDiff(n)/10); end end xlswrite('testnewws11.xls',newfile); even with the cumsum command this code fails when my file has 1,2 time stamps in middle of long missing ones example 8/16/2009 0:00 5.34 8/16/2009 0:10 3.23 8/16/2009 0:20 2.23 8/16/2009 0:30 1.23 8/16/2009 0:50 70 8/16/2009 2:00 5.23 8/16/2009 2:20 544 8/16/2009 2:30 42.23 8/16/2009 3:00 71.23 8/16/2009 3:10 3.23 My output looks like 5.34 3.23 2.23 0 0 0 0 0 0 0 0 0 5.23 544. 42.23 0 0 0 3.23 Any ideas?

Character Jump Control

- by Abdullah Sorathia

I would like to know how can I control the jump movement of a character in Unity3D. Basically I am trying to program the jump in such a way that while a jump is in progress the character is allowed to move either left or right in mid-air when the corresponding keys are pressed. With my script the character will correctly move to the left when, for example, the left key is pressed, but when the right key is pressed afterwards, the character moves to the right before the movement to the left is completed. Following is the script: void Update () { if(touchingPlatform && Input.GetButtonDown("Jump")){ rigidbody.AddForce(jumpVelocity, ForceMode.VelocityChange); touchingPlatform = false; isJump=true; } //left & right movement Vector3 moveDir = Vector3.zero; if(Input.GetKey ("right")||Input.GetKey ("left")){ moveDir.x = Input.GetAxis("Horizontal"); // get result of AD keys in X if(ShipCurrentSpeed==0) { transform.position += moveDir * 3f * Time.deltaTime; }else if(ShipCurrentSpeed<=15) { transform.position += moveDir * ShipCurrentSpeed * 2f * Time.deltaTime; }else { transform.position += moveDir * 30f * Time.deltaTime; } }

Retrofit WebForms with ASP.NET MVC - NoVa Code Camp 2010.2 Demo

- by Soe Tun

Thank you to everyone who attended my Retrofit WebForms with ASP.NET MVC session at NoVa Code 2010.2. It was a fun event for me and I hope you had a great time and learned something from it. I wish I had more time to go over some more important topics in more detail. I *promise* I will be writing blog post series about it since I'll have some vacation time during the December holidays to cover some topics that I didn't get to cover in detail. Please note that the ".bak" file included in the zip file is a SQL Server Database backup file. You have to restore it on your Database server to run it with the source code demo. Please feel free to ask me about the demo project through Twitter or from this blog post. I'll be glad to help you out. If you want me to give this presentation at your .NET User Group, please let me know and I'll be honored to speak there also. Again, thank you all and have a great holiday season. Here is the download link to my Demo project Zip file with the PowerPoint presentation in it. Please let me know if the link doesn't work.

Software vs Network Engineer (Salary, Difficulty, Learning, Happiness)

- by B Z

What are your thoughts on being a Software Engineer vs a Network Engineer? I've been on the software field for almost 10 years now and although I still have a great deal of fun (and challenges), I am starting to think it could be better on the "other" side. Not to degrade network engineers (i know there are many great ones out there), it seems (in general) their job is easier, the learning curve from average to good is not as steep, job is less stressful and pay is better on average. I think as software developer I could make the switch to networking and still enjoy working with computers and feel productive. I spend an enormous amount of time learning about software, practices, new technologies, new patters, etc...I think I could spend a much smaller amount of time learning about networking and be just as "good". What are your thoughts? EDIT: This is not about making easy money. Networking and Software are closely related, I love computers and programming, but if I can work with both, make more money and have less stress in my life and can spend more time with my family, then I am willing to consider a change and hence I am looking for advice that Do or Don't support this view.
