  • Development environment for embedded system

    - by Howard Lee Harkness
    I need to develop software in C/C++ for an embedded system. I have Debian 6 running off of a USB hard drive. I would like to be able to generate a stripped-down kernel with modules, and install them either on a CF card or a USB 'thumb' drive. I succeeded in building a Linux 3.6 kernel and running it in Debian off of the USB hard drive, but I am having trouble figuring out how to install it on the thumb drive. I would like a build cycle that looks like this: 1) Build module or kernel with desired software 2) Install it on thumb drive 3) Boot and test I would like to use the same system for both development and testing, if that is feasible. I am looking for resources and tutorials that would help me understand how to do this.

  • What I Expect From Myself This Year

    - by Lee Brandt
    I am making it a point not to call them resolutions, because the word has become an institution and is beginning to have no meaning. That's why I end up not keeping my resolutions, I think. So in the spirit of holding myself to my own commitments, I will make a plan and some realistic goals. 1.) Lose weight. Everyone has this on their list, but I am going to be conservative and specific. I currently weigh 393lbs. (yeah, I know). So I want to plan to lose 10lbs per month, that's 1lb. every three days, that shouldn't be difficult if I stick to my diet and exercise plan. - How do I do this?     - Diet: vegetarian. Since I already know I have high blood pressure and borderline high cholesterol, a meat-free diet is in order. I was vegan for a little over 2 years in 2006-2008, I think I can handle vegetarian.     - Exercise: at least 3 times (preferably every day) a week for 30 minutes. It has to be something that gets my heart rate up, or burns in my muscles. I can walk for cardio to start and mild calisthenics (girly push-ups, crunches, etc.).         - Move: I spend all my time behind the computer. I have recently started to use a slight variation of the Pomodoro Technique (my Pomodoros are 50 minutes instead of 25). During my 10 minutes every hour to answer emails, chats, etc., I will take a few minutes to stretch. 2.) Get my wife pregnant. We've been talking about it for years. Now that she is done with graduate school and I have a great job, now's the time. We'll be the oldest parents in the PTA most likely, but I don't care. 3.) Blog More. Another favorite among bloggers, but I do have about six drafts for blog posts started. The topics are there all I need to do is flesh out the post. This can be the first hour of any computer time I have after work. As soon as I am done exercising, shower and post. 4.) Speak less. Most people want to speak more. I want to concentrate on the places that I enjoy and that can really use the speakers (like local code camps), rather than trying to be some national speaker. I love speaking at conferences, but I need to spend some more time at home if we're going to get pregnant. 5.) Read more. I got a Kindle for Christmas and I am loving it so far. I have almost finished Treasure Island, and am getting ready to pick my next book. I will probably read a lot of classics for 2 reasons: (1) they teach deep lessons and (2) most are free for the Kindle. 6.) Find my religion. I was raised Southern Baptist, but I want to find my own way. I've been wanting to go to the local Unitarian Church, so I will make a point to go before the end of March. I also want to add a few religious books to my reading list. My boss bought me a copy of Lee Strobel's The Case for Christ: A Journalist's Personal Investigation of the Evidence for Jesus , and I have a copy of Bruce Feiler's Abraham: A Journey to the Heart of Three Faiths (P.S.) . I will start there. Seems like a lot now that I spell it out like this. But these are only starters. I am forty years old. I cannot keep living like I am twenty anymore. So here we go, 2011.

  • What's slowing for loops/assignment vs. C?

    - by Lee
    I have a collection of PHP scripts that are extremely CPU intensive, juggling millions of calculations across hundreds of simultaneous users. I'm trying to find a way to speed up the internals of PHP variable assignment, and looping sequences vs C. Although PHP is obviously loosely typed, is there any way/extension to specifically assign type (assign, not cast, which seems even more expensive) in a C-style fashion? Here's what I mean. This is some dummy code in C: #include <stdio.h> int main() { unsigned long add=0; for(unsigned long x=0;x<100000000;x++) { add = x*59328409238; } printf("x is %ld\n",add); } Pretty self-explanatory -- it loops 100 million times, multiples each iteration by an arbitrary number of some 59 billion, assigns it to a variable and prints it out. On my Macbook, compiling it and running it produced: lees-macbook-pro:Desktop lee$ time ./test2 x is 5932840864471590762 real 0m0.266s user 0m0.253s sys 0m0.002s Pretty darn fast! A similar script in PHP 5.3 CLI... <?php for($i=0;$i<100000000;$i++){ $a=$i*59328409238; } echo $a."\n"; ?> ... produced: lees-macbook-pro:Desktop lee$ time /Applications/XAMPP/xamppfiles/bin/php test3.php 5.93284086447E+18 real 0m22.837s user 0m22.110s sys 0m0.078s Over 22 seconds vs 0.2! I realize PHP is doing a heck of a lot more behind the scenes than this simple C program - but is there any way to make the PHP internals to behave more 'natively' on primitive types and loops?

  • StrongSwan + xl2tpd client timeout between 2-5 minutes

  • Why would cat6 connectors not work with cat5e patch cable?

    - by Lee Tickett
    I had a naff batch of cat5 connectors (the latching mechanism didn't work) so decided to order in some cat6 connectors in preparation for the inevitable upgrade. My existing reel of for making patch cables is cat5e utp stranded. I made up a few cables and tested them- none of them worked. I recrimped and still nothing. When i check them with a multi-meter not all pins are connected. This reel has always worked with the previous cat5 connectors so I tested the cat6 connectors on a reel of solid cat5e cable and they work fine. Any ideas what I might be doing wrong? Or what might be at fault? (cable/connectors) and how I can diagnose? Thanks Lee

  • Named pipe blocking with user nobody

    - by dnagirl
    I have 2 short scripts. The first, an awk script, processes a large file and prints to a named pipe 'myfifo.dat'. The second, a Perl script, runs a LOAD DATA LOCAL INFILE 'myfifo.dat'... command. Both of these scripts work when run locally like so: lee.awk big.file & lee.pl However, when I call these scripts from a PHP webpage, the named pipe blocks: $awk="/path/to/lee.awk {$_FILES['uploadfile']['tmp_name']} &"; $sql="/path/to/lee.pl"; if(!exec($awk,$return,$err)) throw new ZException(print_r($err,true)); //blocks here if(!exec($sql,$return,$err)) throw new ZException(print_r($err,true)); If I modify the awk and Perl scripts so that they write and read to a normal file, everything works fine from PHP. The permissions on the fifo and the normal file are 666 (for testing purposes). These operations run much more quickly through a named pipe, so I'd prefer to use one. Any ideas how to unblock it? ps. In case you're wondering why I'm going to all this aggravation, see this SO question.

  • Launch Webcast Q&A: Oracle WebCenter Suite 11g - The Platform for the Modern User Experience

    - by howard.beader(at)oracle.com
    Did you have a chance to watch the Oracle WebCenter Suite 11g Launch Webcast yet? Andy MacMillan presented some great information on the webcast and answered quite a few of your questions in the Q&A session as well. For your reading pleasure we have captured a number of the questions and answers and they are summarized below: Question: Can you tell me what should our Portal strategy be for integrating and extending our Oracle enterprise applications? Answer: We recommend that you look at this in two steps, the first would be to ensure that you have a good understanding of our common user experience architecture. Internally our product teams at Oracle are already investing in this quite heavily today for Fusion Applications and this is driving natural convergence from a UX strategy standpoint. The second step would be to look at how best to componentize the back office applications so that the business users across your organization can take advantage of these -- don't make it just about putting a new skin on top of what you already have from an application standpoint, instead look at how best to embed the social computing capabilities as part of the solution for your business users. Question: We are currently using the BEA WebLogic Portal now, should we stay on WLP or should we be looking at moving to WebCenter or when should we move to WebCenter? Answer: Our strategy has been called "Continue & Converge", this theme means that you can continue to use WebLogic or Plumtree portals until your organization is ready to move to WebCenter and in the mean time you can continue to deploy what you need to in your organization of WLP or WCI Portals with the full support of Oracle. In addition WebCenter Services can be leveraged for social computing to complement what you are already doing today and enable your organization to take advantage of some of the latest and greatest social computing capabilities. We have migration scripts and conversion capabilities available as well as programs where Oracle can help you evaluate your options to decide how best to move forward. WebCenter provides the best of the best capabilities and will enable you to take advantage of new capabilities that may not exist in your current portal today. In the end though it's up to you as a customer as to when you want to make the transition to Oracle WebCenter Suite. Question: Can you tell me how is Oracle leveraging WebCenter internally and for its Application and Middleware product UX strategies? Answer: Internally, Oracle is leveraging WebCenter for our employees and thus far we are seeing significant updates with our users taking advantage of the business activity streams, team spaces and collaboration capabilities. From a product strategy standpoint, our product teams are taking advantage of the common user experience architecture and leveraging WebCenter to provide social and collaborative capabilities to the Oracle Applications and providing new types of composite applications with what is coming with Fusion Applications. WebCenter also provides a common user experience across all the products in the Oracle Fusion Middleware family as well. Question: Our organization is currently using SharePoint, but we are also an Oracle Applications customer, how should we be thinking about WebCenter as we move forward? Answer: Great question. Typically, we are seeing organizations using SharePoint for its core use cases of small team collaboration and file server replacement. WebCenter can connect to SharePoint as a content source to feed into WebCenter quite easily and it leverages the robust Oracle ECM product under WebCenter as well. In addition, SharePoint team sites can be connected to WebCenter utilizing our SharePoint connector. With Oracle WebCenter though, we are really targeting business users and enterprise applications, thus affecting positive change on the processes that drive the business to improve productivity across your organization. Question: Are organizations today using WebCenter as a Web platform for externally facing public websites? Answer: Yes, we are seeing a convergence around web content management and portal types of websites with customers converting them from just broadcasting content to making it a much richer personalized experience and also exposing back-office applications as well. Web Content Management capabilities are already embedded in WebCenter so that organizations can take advantage now of the benefits a personalized web experience provides for your customers. This is simply a short summary of a few of the questions addressed on the webcast, please tune in now to learn more about Oracle WebCenter, the user experience platform for the enterprise and the web! The Oracle WebCenter Suite 11g Launch Webcast can be found here

  • Oracle Consulting North America is now live on PeopleSoft Services Procurement and PeopleSoft Resource Management

    - by Howard Shaw
    Last month, Oracle's own internal consulting group (OCS North America) went live on PeopleSoft Services Procurement and PeopleSoft Resource Management to manage all aspects of identifying, recruiting, and deploying billable subcontractors on North America Applications customer consulting projects. The primary goals were to enhance the subcontractor staffing process, improve operational and informational processes, and improve collaboration between the Oracle NA Consulting Subcontractor Program and subcontractor suppliers. Over 200 registered external suppliers access the tool, review open needs and competitively bid their resources to work on NA Applications projects. This implementation highlights the usage of Oracle’s own solutions to streamline and enhance business operations, as the PeopleSoft 9.1 applications (Services Procurement and Resource Management) were deployed using Sun hardware, Oracle Enterprise Linux, and Oracle Virtual Machines.For more information, please navigate to the following web pages: PeopleSoft Services Procurement PeopleSoft Resource Management

  • Innovation and the Role of Social Media

    - by Brian Dirking
    A very interesting post by Andy Mulholland of CAP Gemini this week – “The CIO is trapped between the CEO wanting innovation and the CFO needing compliance” – had many interesting points: “A successful move in one area won’t be recognized and rapidly implemented in other areas to multiply the benefits, or worse unsuccessful ideas will get repeated adding to the cost and time wasted. That’s where the need to really address the combination of social networking, collaboration, knowledge management and business information is required.” Without communicating what works and what doesn’t, the innovations of our organization may be lost, and the failures repeated. That makes sense. If you liked Andy Mulholland’s blog post, you need to hear Howard Beader’s presentation at Enterprise 2.0 Conference on innovation and the role of social media. (Howard will be speaking in the Market Leaders Session at 1 PM on Wednesday June 22nd). Some of the thoughts Howard will share include: • Innovation is more than just ideas, it’s getting ideas to market, and removing the obstacles that stand in the way • Innovation is about parallel processing – you can’t remove the obstacles one by one because you will get to market too late • Innovation can be about product innovation, but it can also be about process innovation This brings us to Andy’s second issue he raises: "..the need for integration with, and visibility of, processes to understand exactly how the enterprise functions and delivers on its policies…" Andy goes on to talk about this from the perspective of compliance and the CFO’s concerns. And it’s true: innovation can come both in product innovation, but also internal process innovation. And process innovation can have as much impact as product innovation.  New supply chain models can disrupt an industry overnight. Many people ignore process innovation as a benefit of social business, because it is perceived as a bottom line rather than top line impact. But it can actually impact your top line by changing your entire business model. Oracle WebCenter sits at this crossroads between product innovation and process innovation, enabling you to drive go-to-market innovations through internal social media tools, removing obstacles in parallel, and also providing you deep insight into your processes so you can identify bottlenecks and realize whole new ways of doing business. Learn more about how at the Enterprise 2.0 Conference, where Oracle will be in booth #213 showing Oracle WebCenter and Oracle Fusion Applications.

  • Interesting conversation about the nature of info-wars

    - by Malcolm Anderson
    Over at Schlock Mercenary, Howard Taylor has started a facinating conversation on the nature of Info-Wars. As Howard puts it:   Somebody (I forget who) tweeted that the Wikileaks fight right now is the first infowar in history. I disagree. I think we've fought numerous infowars in the last fifteen years. And that's really what I want to see discussed in the comments. We can argue right and wrong until the eCows come 127.0.0.1 but nobody is going to walk away convinced. I want to see a list of information-age conflicts that you feel qualify as "infowar." Me, I think the RIAA vs file-sharing qualifies. My buddy Rodney suggested RBLs vs Spammers (the spammers won that one.) Somebody pointed out that the Secret Service raid on Steve Jackson Games back in the 80's might qualify.

    I have a web site which is mainly contains a few pages, and now we revamp-ed a new site which contains several hundred pages. We have Strange Google Analytics result, as follow: Before: Traffic sources (all traffic): 674 Content (all pages, unique PV): 674 After: Traffic sources (all traffic): 291 Content (all pages, unique PV): 1235 As you can see, the unique PV has increased as expected (as we have more pages now and the site is better), but why the traffic sources is lower and has a large gap? Any idea?

  • Regulating how much to draw based on how much was drawn last frame.

    - by Mike Howard
    I have a 3D game world on an iPhone (limited graphics speed), and I'm already regulating whether I draw each shape on the screen based on it's size and distance from the camera. Something like... if (how_big_it_looks_from_the_camera > constant) then draw What I want to do now is also take into account how many shapes are being drawn, so that in busier areas of the game world I can draw less than I otherwise would. I tried to do this by dividing how_big_it_looks by the number of shapes that were drawn last frame (well, the square root of this but I'm simplifying - the problem is the same). if (how_big_it_looks / shapes_drawn > constant2) then draw But the check happens at the level of objects which represent many drawn shapes, and if an object containing many shapes is switched on, it increases shapes_drawn lots and switches itself back off the next frame. It flickers on and off. I tried keeping a kind of weighted average of previous values, by each frame doing something like shapes_drawn_recently = 0.9 * shapes_drawn_recently + 0.1 * shapes_just_drawn, but of course it only slows the flickering down because of the nature of the feedback loop. Is there a good way of solving this? My project is in Objective-C, but a general algorithm or pseudo-code is good too. Thanks.

  • Link tracking: Amazon or Google way

    - by Howard
    When doing a shopping site, the best way is to reference some successful stores, like Amazon. In the area of link tracking, for example, to see which section of your frontpage yield better conversion: Amazon way: Generate an unique URL for each link in the frontpage, such as http://www.amazon.com/gp/product/B0083Q04IQ/ref=s9_pop_gw_g424_ir04/175-6575053-9292830?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=0AMJCKBBQA63EP0XHB86&pf_rd_t=101&pf_rd_p=1263340922&pf_rd_i=507846 Google way Use Google Analytics <a href="/products/abc" onClick="javascript: pageTracker._trackPageview('/from-main-menu/products/abc');"> WHat are the pros and cons with the above two approaches (besides Google require JS support)?

  • Having tried differen ways but none worked - How do I disable a service from auto-start at boot in Ubuntu?

    - by Howard Guo
    This really doesn't make sense. I've been using many other distros and never had such difficulty managing autostart services. I found three ways of disabling autostart services, and none of them works for me: update-rc.d -f service_name remove chkconfig --level 12345 service_name off sysv-rc-conf I tried all the three ways to disable mysql daemon, mongo daemon, redis server, cups daemon, yet all of the utilities confirmed that the daemons are disabled, yet they still automatically start on boot. Please suggest the most correct way to disable services from auto-start at boot. Thank you! btw, it's running 12.04

  • 12.04 - why does the network icon dissapear every time my machine is turned off

    - by Howard Walker
    After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

  • G5 quad core will not boot from Ubuntu CD

    I have a PPC G5 Quad Core with Leopard on one hard drive and I want to install Ubuntu on a second hard drive. The second drive is installed and formatted as a Mac OS Extended (Journaled) drive. I have had no success booting from a CD or DVD with various PPC versions of Ubuntu using any of the suggested keys such as "C, Option, or anything else. Booting into open firmware doesn't work as the system can't find the \install\yaboot file. I am using various CD's burned as iso disk images, but none will boot. I have reset the PRAM, etc, to no avail. Beginning to get very frustrated. Can someone shed some light and provide me with a command line in open firmware that will work, or else direct me to a confirmed PPC bootable version of Ubuntu please? I'd appreciate any help you can provide....
