  • 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.

  • Contract Work - Lessons Learned

    - by samerpaul
    I thought I would write a post of a different nature today, but still relevant to the tech world. I do a lot of contract jobs myself and really enjoy it. It's nice to keep jumping from project to project, and not having to go to an office or keep regular hours, etc. I really enjoy it. I have learned a lot in the past few years of doing it (both from experience and from help given to me from others, and the internet) so I thought I'd share some of that knowledge/experience today.So here's my own personal "lesson's learned" that hopefully will help you if you find yourself doing contract work:Should I take the job?Ok, so this is the first step. Assuming you were given sufficient information about what they want, then you should really think about what you're capable of doing and whether or not you should take this job. Personally, my rule is, if I know it's possible, I'll say yes, even if I don't yet know how to do it. That's because the internet is such a great help, it would be rare to run into an issue that you can't figure out with some help. So if your clients are asking for something that you don't yet know how to program, but you know you can do it on the platform then go for it. How else are you going to learn?Use this rule with some limitation, however. If you're really lacking the expertise or foundation in something, then unless you have tons of time to complete the project, then I wouldn't say yes. For example, I haven't personally done any 3d/openGL programming yet so I wouldn't say yes to a project that extensively uses it. OK, so I want the job, but how much do I charge?This part can be tricky. There is no set formula really, but I have some tips for pricing that will hopefully give you a better idea on how to confidently ask your price and have them accept. Here are some personal guidelinesHow much time do you have to complete the project? If it's shorter than average, then charge more. You can even make a subtle note about this (or not so subtle if they still don't get it.) If it seems too short of a time (i.e. near impossible to complete), be sure to say that. It looks bad to promise a time that you can't keep--and it makes it less likely for them to return to you for work.Your Hourly rate: How long have you been working in that language? Do you have existing projects to back you up? Or previous contacts that can vouch for your work? Are there very few people with your particular skill set? All of these things will lend themselves to setting an hourly rate. I'd also try out a quick google search of what your line of work is, to see what the industry standard is at that point in time.I wouldn't price too low, because you want to make your time worth it. You also want them to feel like they're paying for quality work (assuming you can deliver it :) ). Finally, think about your client. If it's a small business, then don't price it too high if you want the job. If it's an enterprise (like a Fortune company), then don't be afraid to price higher. They have the budget for it.Fixed price: If they want a fixed price project, then you need to think about how many hours it will take you to complete it and multiply it by the hourly rate you set for yourself. Then, honestly, I would add 10-20% on top of that. Why? Because nothing ever works exactly how you want it to. There are lots of times that something "trivial" is way harder than it should be, or something that "should work" doesn't for hours and it eats away at your hourly rate. I can't count the number of times I encountered a logical bug that took away an entire's day work because debuggers don't help in those cases. By adding that padding in, it's still OK to have those days where you don't get as much done as you want. And another useful tip: Depending on your client, and the scope, you most likely want to set that you both sign off on a specification sheet before doing any work, and that any changes will result in a re-evaulation of the price. This is to help protect you from being handed a huge new addition to the project half-way in, without any extra payment.Scope of project: Finally, is it a huge project? Is it really small/fast? This affects how much your client will be willing to pay. If it sounds big, they will be willing to pay more for it. If it seems really small, then you won't be able to get away with a large asking price (as easily).Ok, I priced it, now what?So now that you have the price, you want to make sure it feels justified to your client. I never set a price before I can really think about everything. For example, if you're still in your introduction phase, and they want a price, don't give one! Just comment that you will send them a proposal sheet with all the features outlined, and a price for everything. You don't want to shout out a low number and then deliver something that is way higher. You also don't want to shock them with a big number before they feel like they are getting a great product.Make up a proposal document in a word editor. Personally, I leave the price till the very end. Why? Because by the time they reach the end, you've already discussed all the great features you plan to implement, and how it's the best product they'll ever use, etc etc...so your price comes off as a steal! If you hit them up front with a price, they will read through the document with a negative bias. Think about those commercials on TV. They always go on about their product, then at the end, ask "What would you pay for something like this? $100? $50? How about $20!!". This is not by accident.Scenario: I finished the job way earlier than expectedYou have two options then. You can either polish the hell out of the application, and even throw in a few bonus features (assuming they are in-line with the customer's needs) or you can sit and wait on it until you near your deadline. Why don't you want to turn it in too early? Because you should treat that extra time as a surplus. If you said it is going to take you 3 weeks, and it took you only 1, you have a surplus of 2 weeks. I personally don't want to let them know that I can do a 3 week project in 1 week. Why not? Because that may not always be the case! I may later have a 3 week project that takes all 3 weeks, but if I set a precedent of delivering super early, then the pressure is on for that longer project. It also makes it harder to quote longer times if you keep delivering too early.Feel free to deliver early, but again, don't do it too early. They may also wonder why they paid you for 3 weeks of work if you're done in 1. They may further wonder if the product sucks, or what is wrong with it, if it's done so early, etc.I would just polish the application. Everyone loves polish in their applications. The smallest details are what make an application go from "functional" to "fantastic". And since you are still delivering on time, then they are still going to be very happy with you.Scenario: It's taking way too long to finish this, and the deadline is nearing/here!So this is not a fun scenario to be in, but it'll happen. Sometimes the scope of the project gets out of hand. The best policy here is OPENNESS/HONESTY. Tell them that the project is taking longer than expected, and give a reasonable time for when you think you'll have it done. I typically explain it in a way that makes it sound like it isn't something that I did wrong, but it's just something about the nature of the project. This really goes for any scenario, to be honest. Just continue to stay open and communicative about your progress. This doesn't mean that you should email them every five minutes (unless they want you to), but it does mean that maybe every few days or once a week, give them an update on where you're at, and what's next. They'll be happy to know they are paying for progress, and it'll make it easier to ask for an extension when something goes wrong, because they know that you've been working on it all along.Final tips and thoughts:In general, contract work is really fun and rewarding. It's nice to learn new things all the time, as mandated by the project ,and to challenge yourself to do things you may not have done before. The key is to build a great relationship with your clients for future work, and for recommendations. I am always very honest with them and I never promise something I can't deliver. Again, under promise, over deliver!I hope this has proved helpful!Cheers,samerpaul

  • Ubuntu 12.04 using b43-fwcutter

    - by Nathan
    I have used 10.04 with the b43-fwcutter driver to drive my BCM4318 Broadcom card (a Linksys WPC54G v3) on my old Dell Inspiron 8100 for two years+ with no troubles. I just upgraded to 12.04 and although everything worked fine after install, before I added the b43-fwcutter driver, once I installed the driver, the system refuses to boot. Even before I install the Linksys card!! It just hangs on boot with graphical garbage on the screen. I tried several attempts to recover the system using the live CD, and finally reinstalled completely. I have been thru the cycle, install fresh system, verify everything works, then install b43-fwcutter and it is hung, several times. Consistent hard fail. The system runs fine on hardwire Ethernet, and wireless was fine on 10.04. But I cannot get there with 12.04. So after several attempts, I am now ready to admit defeat and ask for help. I have read every thread that search turned up, and either the advice is to do what I did, i.e. install fwcutter, or does not apply (Different Broadcom, STA, legacy, whatever) So what do I need to do to fix it? Or is the B43-fwcutter driver broken for 12.04? Thoughts? Tips? Log files needed??

  • Team Software Development using Ruby on Rails

    - by Panoy
    I used to work alone on small to medium sized programming projects before and have no experience working in a team environment. Currently, there will be 3 of us in an in-house software development team that is tasked to develop a number of software for an academic institution. We have decided to use the web for the majority of the projects and are planning to choose Ruby on Rails for this and I would like to ask for your inputs, advices and approaches with regards to software development as a team using the RoR web framework. One thing that has really confounded me is how you divide the programming tasks of a project if there are 3 of you that are really doing the coding. It’s obvious that we as developers approach a problem in a modular way and finish it one after another. If the project consists of 3 modules, should each one of us focus on each of those modules? Would it be faster that way? How about if the 3 of us would focus on one module first (that’s what I really prefer). Is using a distributed version control system such as Git the answer to this type of problem? Please don’t forget to put your tips and experiences with regards to team software development. Cheers!

  • Selling an open source project: some issues

    - by Sander
    I am the creator / main developer of a small sized open source (PHP) project (GPL3). Currently there is a development team of 3 people (me included). This team has been quite active for some time, but since almost 2 years not much has happened. I myself have decided I want to stop working on the project, but I can't just leave the project because I care about it and I know if I abandon it, it will just be a matter of time before the project completely dies. At this moment, there are still some users and the project is only slightly out-of-date. So I'm thinking about selling the whole project. Of course I'd need to get consent of the other developers, but for now I'm assuming that's not a big problem. So at this moment I have 2 questions: 1) If the project would be sold to a commercial party, would it be possible for them to convert the project to closed source? I would prefer to sell the project to a company/organization that would continue the development under an open source license. 2) Does anyone have any tips to find interested parties? I don't know if I just want to put up a "For Sale" sign on the website of the project. Maybe someone has experience with a comparable situation. Ok guys, thanks in advance!

  • How do I keep controversy in check?

    - by Aaron Digulla
    This is probably OT but it's less OT here than on any other SO site, so please bear with me. I'm working on a new project votEm. The goal is to give independent candidates a platform to introduce themselves to get elected for a political office. My main reason is that today, it's too expensive to run for an office. Some politicians in the US spend as much as 30 million dollars (!) for a single campaign. That money is better spent elsewhere. In a similar fashion, people who want to change countries like Egypt, could use such a platform to present themselves. Now I expect a lot of emotions and pressure on my site. People with a lot of money (and a lot to lose) will try to game it (political parties, secret services of ... errr ... "not 100% democratic countries", big companies, ...) To avoid as many mistakes as possible, I need a list of resources, ideas and tips how to keep such a site out of too much trouble. PS: I'd make this CW but the option seems to be gone...

  • How to Change the Cmd+Q Shortcut Key in OS X (to Stop Accidentally Closing Apps)

    - by The Geek
    If you’ve spent any time using Mac OS X, you’ve figured out that the Cmd+W shortcut key closes a window or tab, while the Cmd+Q key quits the entire app. The problem? The keys are right next to each other, and way too easy to accidentally hit! Here’s how to change it. This problem is compounded even more when you’re using an application like Google Chrome, Safari, or Firefox, where you’re opening or closing tabs all the time, and probably using the Cmd+W key to close just the current tab. If you aren’t careful, you’ll accidentally hit Cmd+Q instead, and your entire browser gets closed.

  • Cuda driver, CPU/GPU performances issue

    - by elect
    I implemented a RNS Montgomery exponentiation in Cuda and on cpu for comparison. Everything nice everything fine. It runs on just one SM. However I am going to tell you some strange regression in both cpu/gpu performances. During the devoloping, about two month ago, I was using Cuda 5 preview on Ubuntu 11.04 64b. In this time, I reach the following performances: cpu 460ms gpu 120ms Then one day when I turn on the pc, the graphical environment didnt start. I dont know which was the problem, however I switched to the console and installed again the Cuda driver. At the following boot performances changed: cpu 310ms gpu 80ms I was like Q.Q...uhm ok, nice to see this, but I was wondering how that could be possible However, I went then in holiday for 10 days and I continued developing and optimizing on my notebook (but not the same part of the code, some additional stuff) When I was back, I just updated the source files, and performances came back to 460/120ms.. I couldnt believe it, I tried to install Cuda 5 RC, updating the video driver too... nothing changed... I checked Debug/Release, Cuda computability, but the problem seems being somewhere else.. Looking around the net I found this, I am pretty sure it must have something to do with the driver, because the performance change affected both cpu and gpu Do you have some tips/ideas/suggestions?

  • MSDN Live 2010 &ndash; Delivered : 24 sessions (4 x 6) on Visual Studio and Team Foundation Server

    - by terje
    We (Mikael Nitell and me) got a whole track on the Norwegian MSDN Live tour this year.  We did these as a pair, and covered 4 cities over 4 days, 6 sessions per day, taking 8 hours to come through it.  The Islandic volcano made the travels a bit rough, but we managed 6 flights out of 8. The first one had to go by van instead, 7-8 hour drive each way together with other MSDN Live presenters – a memorable tour! Oslo was the absolute top point.  We had to change hall to a bigger one. People were crowding, and even the big hall was packed!  The presentations were mostly based on demos, but we had a few slides as well.  They have been uploaded to my SkyDrive.  Info to aliens – some of the text may be Norwegian. The sessions were as follows: Overview of news in Visual Studio and Team Foundation server 2010 Ensuring Quality with VS/TFS 2010 Releasing products with VS/TFS 2010 No More No Repro with VS/TFS 2010 Performance Testing and Parallel Programming with VS/TFS 2010 Migrating to VS/TFS 2010 Tips, tricks, news and some best practices with VS/TFS 2010   In the coming days, I will post up examples from the demos too, with explanations of how they are intended to work. These entries will also contain stuff we had to remove from the actual presentations due to the time constraints. We managed to create recordings of two of the sessions, which will be uploaded to Channel 9 by Microsoft, afaik.   I will update this blog with information about exact locations when that is done. Also note we’re (read:Osiris Data AS) running both Upgrade and Deep Dive courses  on VS/TFS 2010 now in May.  Please look here for more info. If you want to be informed, follow me on Twitter.  All blog entries will be announced on twitter.

  • Want to tap into a niche market. Do I create new site or bolt on to existing site?

    - by nitbuntu
    Hi, After a lot of heard work and a few years of perseverance, I'm seeing regular sales on my website which have been steadily growing over the past year. However, the entrepreneur in me wants tap into a niche market which I've become very interested in. It's possible to bolt on this niche onto my existing site as an additional category, without it looking too out of place; my new category of products would also benefit from the ranking my current site gets. The kind of people who would purchase these new niche products, however, are very particular and obsessive about detail. So, for example, many Vegetarians would not eat in KFC even if they were to introduce a new range of Veggie burgers. So, I thought it best to create a new website and since my existing site was created using an 'old-school' shopping cart and there are many more up-to-date, feature-rich, ones available now, I wanted to use a different shopping cart system. My dilemma is that I already have 2 websites (1 b2c and another b2b site) and maintaining a 2nd b2c site would end up vastly increasing my workload and I fear that I would not be able to pay adequate attention to all the sites. Moreover, the additional customer service work (e.g. answering emails from many separate email accounts) could end up being too confusing and difficult to maintain. The easy answer would be to take on an employee, but I'm just not earning enough to justify this yet. If anyone has any tips or experience they'd like to share, which could help me answer this question, I'd be highly grateful.

  • How do I parse a header with two different version [ID3] avoiding code duplication?

    - by user66141
    I really hope you can give me some interesting viewpoints for my situation, because I am not satisfied with my current approach. I am writing an MP3 parser, starting with an ID3v2 parser. Right now I`m working on the extended header parsing, my issue is that the optional header is defined differently in version 2.3 and 2.4 of the tag. The 2.3 version optional header is defined as follows: struct ID3_3_EXTENDED_HEADER{ DWORD dwExtHeaderSize; //Extended header size (either 6 or 8 bytes , excluded) WORD wExtFlags; //Extended header flags DWORD dwSizeOfPadding; //Size of padding (size of the tag excluding the frames and headers) }; While the 2.4 version is defined : struct ID3_4_EXTENDED_HEADER{ DWORD dwExtHeaderSize; //Extended header size (synchsafe int) BYTE bNumberOfFlagBytes; //Number of flag bytes BYTE bFlags; //Flags }; How could I parse the header while minimizing code duplication? Using two different functions to parse each version sounds less great, using a single function with a different flow for each occasion is similar, any good practices for this kind of issues ? Any tips for avoiding code duplication? Any help would be appreciated.

  • "Oracle Coherence 3.5" Book - My Humble Review

    - by [email protected]
      After reviewing the book in more detail I say again that it is a great guide for sure. Lots of important concepts that sometimes can be somewhat confusing are deeply reviewed, including all types of caching schemes and backing maps, and the cache topologies with their corresponding performances and very useful "When to use it?" sections. Some functionalities that are very desirable or used a lot are reviewed with examples and best practices of implementation, including: Data affinity Querying Pagination Indexes Aggregations Event processing, listening and triggering Data persistence Security Regarding the networking and architecture topics, Coherence*Extend is exhaustively reviewed, including C++ and .NET clients, with very good tips and examples, even including source codes. Personally, I am also glad to see that the address providers (<address-provider> tag), new feature in Coherence 3.5 which is a way to programmatically provide well-known addresses in order to connect to the cluster, is mentioned on the book, because it provides new functionalities to satisfy some special configuration requirements for example: Provide a way to switch extend nodes in cases of failure Implement custom load balancing algorithms and/or dynamic discovery of TCP/IP connection acceptors Dynamically assign TCP address and port settings when binding to a server socket Another very interesting and useful section is the "Coherent Bank Sample Application", which is a great tutorial, useful to understand how Coherence interacts with third party products establishing a clear integration with them, including the use of non-Oracle products like MS Visual Studio.

  • System in low graphics, deleted linux, grub rescue, can't access windows

    - by First timer
    So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

  • General List of Common Programming Errors

    - by javamonkey79
    As one journey's from apprentice to journeyman to master I've noticed that one accumulates a list of best practices for things they've been bitten by. Personally, I write most of my stuff in java & SQL so my list tends to be slated towards them. I've accumulated the following: When doing list removal, always reverse iterate Avoid adding items to a list you are currently iterating on Watch out for NullPointerExceptions Now, I know there are language specific "common errors" links out there like this one. And I'm also aware of the pragmatic programmer tips, Martin Fowler's "code smells". Does anyone know of any good lists out there of things like I've listed above (re: list removal, adding items, etc). My guess is that there are some good QA folks out there that can probably throw me a bone here. I'm not looking for things the compiler can catch - I'm looking for common things that cause bugs. In the event that there isn't a list out there already then I welcome posting your own findings here. Thanks in advance!

  • As a developer, how do I learn sales? [closed]

    - by Dan Abramov
    I quit the company I was working for to pursuit an opportunity as a startup, and I believe in our product. I'm sure it's going to be great if we attract some customers first to keep going. (I don't want funding.) Our product is targeted at private schools and courses, and helps organize the mess other LMSs introduce. The problem is, our team is basically just me and I have very little idea about sales and marketing. I can do reasonably good copywriting but I'm sure I can do better—and being nervous or too techy in a real world conversation with the client doesn't help. I want to get better, in fact, a lot better at negotiating with clients and pitching my product. I did look for some “sales articles” on the web, and a lot of what I found is plain bullshit on SEO-engineered websites promoting books or $5000 courses. What I need instead is a developer's perspective on how to sale a product you think is great. What are typical programmer's mistakes and misconceptions about sales, and how to avoid them? How do you evolve into a reasonably great salesman? I can't believe it's in the mindset and unlearnable. Your own experience, combined with great articles available on the web is most welcome. To Future Readers The question got closed because it is not a good fit for this site. I found some helpful tips in a similar question asked on a sister StackExchange site about startups: I'm a terrible salesperson. What can I do about it?

  • User Switching in XFCE 12.04 with LightDM and dumping unneeccesary Gnome libs

    - by user111120
    I'm an elder non-techie Mac-to-Linux convert trying to play the linux tech game by ear, so please be gentle! :) I am running XFCE Ubuntu 12.04 totally on a 8-gig flash drive and it's fantastic. I am starting to run into potential space issues (down to 1.0 gig free from 1.9 gigs since being installed last summer), most likely because of growing Thunderbird mail files, and this prompted my question. I just installed lightDM on my system because I want the ability to switch users in XFCE if I follow instructions on another blog. They advised using LightDM instead of GDM because LightDM doesn't download Gnome libraries. That's great since I need the space, but my question is how can I tell whether I don't already have Gnome libraries installed from other updates and such? And can I minimize having any Gnome libraries? The method for me to switch users entails creating a "fast-user-switch" file in /usr/local/bin; is there any easier way? One last thing so I din't have topen another needless thread; while experimenting I somehow lost the share folder in one of my accounts. Is there any way to get a share folder back? Thanks for any tips! Jim in NYC

  • How can I learn more about ADF?

    - by jhpierce -Oracle
    Look to the Oracle Technology Network for a wealth of information, tutorials, best practices and coding examples. The place to start is the Oracle Application Development Framework (ADF) web page. The Oracle ADF page has basic information and downloads for ADF, but the real wealth is in the links to other pages. One of the pages is the Oracle ADF Code Corner,  which is a blog-style column that provides hints, tips and coding examples for ADF developers. The content on this page ranges from easy to complex and often contains advanced programming concepts. The content is inspired by questions asked on the Oracle JDeveloper customer forum on OTN. The ADF Code Corner has many articles that will inspire your imagination and possibly solve your coding problem.How about the Oracle ADF Architecture Square link? The Oracle ADF Architecture Square focuses on architectural issues and developer guidelines for writing ADF software solutions. The goal is to give ADF developers an understanding of the necessary decisions for building a successful ADF application, to offer potential architectural blueprints to choose from when putting the ADF application together, and to provide potential ADF best practices to take back to your development team. The Oracle ADF Mobile link gives information on developing mobile applications for iOS and Android based applications. There are links to ADF Mobile Overview, ADF Mobile demos and ADF Mobile courses.The Sample ADF Applications link lists sample applications and other resources where you can find code samples for ADF. These are complete ADF applications that can be downloaded into JDeveloper and give you insight into coding an application.There are many more links found under the "Learn More" tab that can equip the developer with the knowledge they need to develop their applications. There are links to overview papers, technical resources, related topics and available training. The information you need IS just a click away.

  • How is determined an impact of a requirement change on the existing code?

    - by MainMa
    Hi, How companies working on large projects evaluate an impact of a single modification on an existing code? Since my question is probably not very clear, here's an example: Let's take a sample business application which deals with tasks. In the database, each task has a state, 0 being "Pending", ... 5 - "Finished". A new requirement adds a new state, between 2nd and 3rd one. It means that: A constraint on the values 1 - 5 in the database must be changed, Business layer and code contracts must be changed to add a new state, Data access layer must be changed to take in account that, for example the state StateReady is now 6 instead of 5, etc. The application must implement a new state visually, add new controls for it, new localized strings for tool-tips, etc. When an application is written recently by one developer, it's more or less easy to predict every change to do. On the other hand, when an application was written for years by many people, no single person can anticipate every change immediately, without any investigation. So since this situation (such changes in requirements) is very frequent, I imagine there are already some clever techniques and ways to predict the impact. Is there any? Do you know any books which deal about this subject? Note: my question is not related to How do you deal with changing requirements? question. In fact, I'm not interested in evaluating the cost of a change, but rather the way to predict the parts of an application which will be concerned by the change. What will be those changes and how difficult they are really doesn't matter in my question.

  • Blocking popups and ads

    - by user74364
    I'm having a fight with ads, popups and tracking cookies. But i'm having some issues. Software used: Chromium 18.0.1025.168 Extensions used: Adblock Plus (Beta)1.2 AdBlock+ Element Hiding Helper1.1.9.18 Better Pop Up Blocker2.1.6 Ghostery3.0.0 With this configuration, i'm always getting this error: Warning: This extension failed to modify a network request because the modification conflicted with another extension. I know if i disable "better popup", this goes away. It's perfectly normal, due to those extensions trying to block the same things. Problem is, i can't live without all of them! Can anyone advise me about some good configuration? Can't live without adblock plus, because i hate ads. Betterpopup blocker is essential too (believe me, chrome doesn't block a lot of popups, and i have a website or 2 that can proove that.) And ghostery is a must... i can't bare the idea of being tracked all the time by some companies. So i'm kinda lost here! everything is needed, but they conflict with each other. i mean, it has to exist a perfect combination out there, i know i'm not the only one hating the privacy issues nowadays! really thankful for any tips guys

  • Graphical Interface and Object Selection/Manipulation

    - by ToriArendt
    I have a project I want to try to implement, but I'm kind of stuck on how to get started. I know there are probably a lot of resources that I can look at, but I'm really just stuck on what to even search for and where to begin. Basically, I have a program written in Java that separates 3D coordinates from a 3D reconstructed model into different objects. I then want to be able to perform a logistic regression on these objects to determine if they are type A or type B. But first, I need to classify a training set of objects as type A or B by hand. I don't know ANYTHING about graphing or user interfaces in Java, so I have been plotting the coordinates of a given object in MATLAB so that I can visualize the object and assign it a type. Now, as I am trying to make this program more "user friendly" I want to create an interface in Java where I can simply graph all the coordinates of the objects from the entire 3D model (on the same graph). I then want to be able to click on the each object and assign it to be either of type A or type B. I hope this description makes sense and someone can point me in the direction of something that will help me. I'm sorry if some of this terminology is off; I'm a bit new to software development. P.S. If anyone also has some tips on implementing logistic regression in Java, I'm sure I'll need them down the road :).

  • Install Base Transaction Error Troubleshooting

    - by LuciaC
    Oracle Installed Base is an item instance life cycle tracking application that facilitates enterprise-wide life cycle item management and tracking capability.In a typical process flow a sales order is created and shipped, this updates Inventory and creates a new item instance in Install Base (IB).  The Inventory update results in a record being placed in the SFM Event Queue.  If the record is successfully processed the IB tables are updated, if there is an error the record is placed in the csi_txn_errors table and the error needs to be resolved so that the IB instance can be created.It's extremely important to be proactive and monitor IB Transaction Errors regularly.  Errors cascade and can build up exponentially if not resolved. Due to this cascade effect, error records need to be considered as a whole and not individually; the root cause of any error needs to be resolved first and this may result in the subsequent errors resolving themselves. Install Base Transaction Error Diagnostic Program In the past the IBtxnerr.sql script was used to diagnose transaction errors, this is now replaced by an enhanced concurrent program version of the script. See the following note for details of how to download, install and run the concurrent program as well as details of how to interpret the results: Doc ID 1501025.1 - Install Base Transaction Error Diagnostic Program  The program provides comprehensive information about the errors found as well as links to known knowledge articles which can help to resolve the specific error. Troubleshooting Watch the replay of the 'EBS CRM: 11i and R12 Transaction Error Troubleshooting - an Overview' webcast or download the presentation PDF (go to Doc ID 1455786.1 and click on 'Archived 2011' tab).  The webcast and PDF include more information, including SQL statements that you can use to identify errors and their sources as well as recommended setup and troubleshooting tips. Refer to these notes for comprehensive information: Doc ID 1275326.1: E-Business Oracle Install Base Product Information Center Doc ID 1289858.1: Install Base Transaction Errors Master Repository Doc ID: 577978.1: Troubleshooting Install Base Errors in the Transaction Errors Processing Form  Don't forget your Install Base Community where you can ask questions to help you resolve your IB transaction errors.

  • Parsing an header with two different version [ID3] avoiding code duplication?

    - by user66141
    I really hope you could give me some interesting viewpoints for my situation, my ways to approach my issue are not to my liking . I am writing an mp3 parser , starting with an ID3v2 parser . Right now I`m working on the extended header parsing , my issue is that the optional header is defined differently in version 2.3 and 2.4 of the tag . The 2.3 version optional header is defined as follows : struct ID3_3_EXTENDED_HEADER{ DWORD dwExtHeaderSize; //Extended header size (either 6 or 8 bytes , excluded) WORD wExtFlags; //Extended header flags DWORD dwSizeOfPadding; //Size of padding (size of the tag excluding the frames and headers) }; While the 2.4 version is defined : struct ID3_4_EXTENDED_HEADER{ DWORD dwExtHeaderSize; //Extended header size (synchsafe int) BYTE bNumberOfFlagBytes; //Number of flag bytes BYTE bFlags; //Flags }; How could I parse the header while minimizing code duplication ? Using two different functions to parse each version sounds less great , using a single function with a different flow for each occasion is similar , any good practices for this kind of issues ? any tips for avoiding code duplication ? anything would be great .
