  • Many small scripts, one repository or multiple?

    - by The Jug
    A co-worker and myself have run into an issue that we have multiple opinions on. Currently we have a git repository that we are keeping all of our cronjobs in. There are about 20 crons and they are not really related except for the fact that they are all small python scripts and essential for some activity. We are using a fabric.py file to deploy and a requirements.txt file to manage requirements for all of the scripts. Our issue is basically, do we keep all of these scripts in one git repository or should we be separating them out into their own repositories? By keeping them in one repository it is easier to deploy them onto one server. We can use just one cron file for all the scripts. However this feels wrong, as the 20 cronjobs are not logically related. Additionally, when using one requirements.txt file for all the scripts, it's hard to figure out what the dependencies are for a particular script and they all have to use the same versions of packages. We could separate all of the scripts out into their own repositories but this creates 20 different repositories that need to be remembered and dealt with. Most of these scripts are not very large and that solution seems to be overkill. A related question is, do we use one big crontab file for all cronjobs, or a separate file for each? If each has their own, how does one crontab's installation avoid overwriting the other 19? This also seems like a pain as there would then by 20 different cron files to keep track of. In short, our main question and issue is do we keep them all closely bundled as one repository or do we separate them out into their own repository with their own requirements.txt and fabfile.py? We feel like we're also probably looking over some really simple solution. Is there an easier way to deal with this issue?

  • SQL Azure Roadmap gets a little clearer &ndash; announcements from Tech Ed

    - by Eric Nelson
    On Monday at Tech?Ed 2010 we announced new stuff (I like new stuff) that “showcases our continued commitment to deliver value, flexibility and control of data through data cloud services to our customers”. Ok, that does sound like marketing speak (and it is) but the good news is there is some meat behind it. We have some decent new features coming and we also have some clarity on when we will be able to get our hands on those features. SQL Azure Business Edition Extends to 50 GB – June 28th SQL Azure Business Edition database is now extending from 10GB to 50GB The new 50GB database size will be available worldwide starting June 28th SQL Azure Business Edition Subscription Offer – August 1st Starting August 1st, we will have a new discounted SQL Azure promotional offer (SQL Azure Development Accelerator Core) More information is available at http://www.microsoft.com/windowsazure/offers/.

  • Library Organization in .NET

    - by Greg Ros
    I've written a .NET bitwise operations library as part of my projects (stuff ranging from get MSB set to some more complicated bitwise transformations) and I mean to release it as free software. I'm a bit confused about a design aspect of the library, though. Many of the methods/transformations in the library come with different endianness. A simple example is a getBitAt method that regards index 0 as the least significant bit, or the most significant bit, depending on the version used. In practice, I've found that using separate functions for different endianness results in much more comprehensible and reusable code than assuming all operations are little-endian or something. I'm really stumped regarding how best to package the library. Should I have methods that have LE and BE versions take an enum parameter in their signature, e.g. Endianness.Little, Endianness.Big? Should I have different static classes with identically named methods? such as MSB.GetBit and LSB.GetBit On a much wider note, is there a standard I could use in cases like this? Some guide? Is my design issue trivial? I have a perfectionist bent, and I sometimes get stuck on tricky design issues like this... Note: I've sort of realized I'm using endianness somewhat colloquially to refer to the order/place value of digital component parts (be they bits, bytes, or words) in a larger whole, in any setting. I'm not talking about machine-level endianness or serial transmission endianness. Just about place-value semantics in general. So there isn't a context of targeting different machines/transmission techniques or something.

  • Code structure for multiple applications with a common core

    - by Azrael Seraphin
    I want to create two applications that will have a lot of common functionality. Basically, one system is a more advanced version of the other system. Let's call them Simple and Advanced. The Advanced system will add to, extend, alter and sometimes replace the functionality of the Simple system. For instance, the Advanced system will add new classes, add properties and methods to existing Simple classes, change the behavior of classes, etc. Initially I was thinking that the Advanced classes simply inherited from the Simple classes but I can see the functionality diverging quite significantly as development progresses, even while maintaining a core base functionality. For instance, the Simple system might have a Project class with a Sponsor property whereas the Advanced system has a list of Project.Sponsors. It seems poor practice to inherit from a class and then hide, alter or throw away significant parts of its features. An alternative is just to run two separate code bases and copy the common code between them but that seems inefficient, archaic and fraught with peril. Surely we have moved beyond the days of "copy-and-paste inheritance". Another way to structure it would be to use partial classes and have three projects: Core which has the common functionality, Simple which extends the Core partial classes for the simple system, and Advanced which also extends the Core partial classes for the advanced system. Plus having three test projects as well for each system. This seems like a cleaner approach. What would be the best way to structure the solution/projects/code to create two versions of a similar system? Let's say I later want to create a third system called Extreme, largely based on the Advanced system. Do I then create an AdvancedCore project which both Advanced and Extreme extend using partial classes? Is there a better way to do this? If it matters, this is likely to be a C#/MVC system but I'd be happy to do this in any language/framework that is suitable.

  • Extending AutoVue Through the API

    - by GrahamOracle
    The AutoVue API (previously called the “VueBean” API) is a great way to extend AutoVue Client/Server Deployment – specifically the client component – beyond the out-of-the-box capabilities and into new use-cases. In addition to having a solid grasp of J2SE programming, make sure to leverage the following resources if you’re developing or interested in developing customizations/extensions to AutoVue Client/Server Deployment: Programmer’s Guide: Before all else, read through the AutoVue API Programmer’s Guide to get an understanding of the architecture of the API. The Programmer’s Guide is included with the installation of AutoVue, and is posted on the Oracle Technology Network (OTN) website for the recent versions of AutoVue: http://www.oracle.com/technetwork/documentation/autovue-091442.html Javadocs: The AutoVue API Javadocs document the many packages, classes, and methods available to you. The Javadocs are included in the product installation under the \docs\JavaDocs\VueBean folder (easiest starting point is through the file index.html). Integrations Forum: If you have development questions that aren’t answered through the documentation, feel free to register and post in the public AutoVue Integrations Forum. For more information refer to the following blog post from October 2010: https://blogs.oracle.com/enterprisevisualization/entry/exciting_news_autovue_integrat Code Samples: Although the Oracle Support team’s scope of Support for API/customization topics is to answer questions regarding information already provided in the documentation (i.e. not to design or develop custom solutions), there are cases where Support comes across interesting samples or code snippets that may benefit various customers. In those cases, our Support team posts the samples into the Oracle knowledge base, and tracks them through a single reference note. The link to the KM Note depends on how you currently access the My Oracle Support portal: Flash interface: https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=REFERENCE&id=1325990.1 (New) HTML interface: https://supporthtml.oracle.com/epmos/faces/ui/km/SearchDocDisplay.jspx?type=DOCUMENT&id=1325990.1 Happy coding!

  • ODI 11g – Faster Files

    - by David Allan
    Deep in the trenches of ODI development I raised my head above the parapet to read a few odds and ends and then think why don’t they know this? Such as this article here – in the past customers (see forum) were told to use a staging route which has a big overhead for large files. This KM is an example of the great extensibility capabilities of ODI, its quite simple, just a new KM that; improves the out of the box experience – just build the mapping and the appropriate KM is used improves out of the box performance for file to file data movement. This improvement for out of the box handling for File to File data integration cases (from the 11.1.1.5.2 companion CD and on) dramatically speeds up the file integration handling. In the past I had seem some consultants write perl versions of the file to file integration case, now Oracle ships this KM to fill the gap. You can find the documentation for the IKM here. The KM uses pure java to perform the integration, using java.io classes to read and write the file in a pipe – it uses java threading in order to super-charge the file processing, and can process several source files at once when the datastore's resource name contains a wildcard. This is a big step for regular file processing on the way to super-charging big data files using Hadoop – the KM works with the lightweight agent and regular filesystems. So in my design below transforming a bunch of files, by default the IKM File to File (Java) knowledge module was assigned. I pointed the KM at my JDK (since the KM generates and compiles java), and I also increased the thread count to 2, to take advantage of my 2 processors. For my illustration I transformed (can also filter if desired) and moved about 1.3Gb with 2 threads in 140 seconds (with a single thread it took 220 seconds) - by no means was this on any super computer by the way. The great thing here is that it worked well out of the box from the design to the execution without any funky configuration, plus, and a big plus it was much faster than before, So if you are doing any file to file transformations, check it out!

  • Why do people crawl sites without downloading pictures?

    - by Michael
    Let me show you what I mean: IP Pages Hits Bandwidth 85.xx.xx.xxx 236 236 735.00 KB 195.xx.xxx.xx 164 164 533.74 KB 95.xxx.xxx.xxx 90 90 293.47 KB It's very clear that these person are crawling my site with bots. There's no way that you could visit my site and use <1MB bandwidth. You might say that there's the possibility that they could be browsing the site using some browser or plug-in that does not download images, js/css files, etc., but the simple fact of the matter is that there are not 90-236 pages that are linked from the home page (outside of WP files), even if you visited every page twice. I could understand if these people were crawling the site for pictures, but once again, the bandwidth indicates that this isn't what is happening. Why, then, would they crawl the site to simply view the HTML/txt/js/etc. files? The only thing that I can come up with is that they are scanning for outdated versions of WordPress, SQL injection vulnerabilities, etc., which makes me inclined to outright ban the IPs, but I'm curious, is it possible that this person is a legitimate user, or at the very least, not intending to be harmful?

  • Cross platform development query

    - by Ian
    I'm a Microsoft developer mainly, but there are a couple of small-ish projects I'd like to fiddle with which would benefit from being cross platform. The platforms I want to target are: Windows, Linux, Mac, Android and preferably iPhone, web (running in a browser). I need 3D (Around the level of support seen in something like Minecraft (I'm not writing Minecraft)), some networking. I'm pretty certain Java would work on all except iPhone. Looking at the "related questions" above it's offered up QT (no browser or phone afaik) and also HTML/CSS/Javascript (3D? package for desktop?) The other alternative is to have seperate versions for seperate platforms, developed with some common code where possible. That option isn't something I know anything about. Does anyone have experience of this sort of conundrum? I figured here was better than SO, because I imagine there are compromises which extend beyond technical choice. Finally, this is not a commercial operation, so some of the very expensive cross platform tools are out of the question unless they offer some sort of community edition. Thanks for your time.

  • Compiling C++ code with mingw under 12.04

    - by golemit
    I tried to setting up compiling of the C++ projects under my Ubuntu 12.04 by mingw with QT libraries. The idea was to get executable independent from variations of target Windows versions and development environments of my colleagues. It was successfully implemented under OpenSuse 12.2 with mingw32 and some additional libraries including mingw32-libqt4 and some others. Fine. However when trying to do the same under Ubuntu 12.04 with mingw-w64 including latest libraries QT-4.8.3 copied from Windows there were always errors. No luck. The typical errors in these attempts can be seen in attachments. The commands used: qmake -spec /path_to_my_conf/win32-x-g++ my_project.pro make Can someone give a hint of the problem source? I would appreciate a good advice.

  • LDAP + LTSP 12.04

    - by us3r
    On ubuntu 12.04 i have some kind of problem with LTSP and LDAP. Sometimes I can log to the server, but sometimes I cant (window freezes on LDM) from thin client. Everything is ok when I log to the server like the local machine, but I have some kind of problem on thin client. pam_mkhomedir.so creates home dir, but i cant log..because Nothing happened - ldm freezes. This problem doesnt exist for "local" users (unix accounts) and on first logged LDAP user. It's important to mention that in log I can see nothing special. Does anybody have a problem with ltsp + ldap on ubuntu 12.04? There wasn't any problem on the previous versions. ps sorry for my english skills ;) EDIT: When LDM freezes in the logs there is something: May 17 11:59:52 bar sshd[6066]: Accepted password for student2 from 192.168.100.22 port 44000 ssh2 May 17 11:59:52 bar sshd[6066]: pam_unix(sshd:session): session opened for user student2 by (uid=0) May 17 12:00:03 bar sshd[6315]: subsystem request for sftp by user student2 And nothing other for this user.

  • Compiz slow under proprietary nvidia driver

    - by gsedej
    Hi! I am using Ubuntu 10.10 and have problem with proprietary nvidia driver for my GeForce GTS 250. I have issue with poor Compiz performance. And there is also open-source "noueau" driver. Proprietary: I tried many versions but neither works fast on desktop. This means 30 FPS without heavy effects. Currently I am using version 270.18. Even normal desktop use feels bad (moving windows) In games (and 3D benchmark) it is really good! (Unigine Heaven works good!) Open-source "nouveau": Very fast on desktop with heavy effects (blur, ...). I have 300 FPS and more, even in Expo mode. Games were good but not as good as prop. And driver causes xorg to crash even the latest (ppa:xorg-edgers/nouveau), so I switched back to proprietary. I also have computer with Ubuntu 10.04, GeForce 8600GT and drivers around 185.x and Compiz works great there. There is similar question Nvidia proprietary driver performance in 10.10 Which version of nvidia (prop) driver is fast in Compiz in Ubuntu 10.10? How do you install a specific version of nvidia driver? Is it the case that each newer driver works slower on compiz?

  • Multilingual website without language component in the URL

    - by user359650
    I'm working on a website for Canada which will have French and English versions. For SEO purposes, I would like to avoid using any language tag in URLs because I believe it will have more impact (e.g. example.ca/products better than en.example.ca/products or example.ca/en/products). I believe this is technically possible because the2 languages are sufficiently different that the URLs won't be conflicting with one another (e.g. if you want a "product" page, it will be /products in English, and /produits in French so you know which language the URL is about). Since Google (and most likely others) doesn't rely on the URL (nor HTML tags) to determine the content language I don't see any problems with search engines. To make this possible I've thought about using a cookie distinct from the session cookie (e.g. example.org_language) with long term expiry (e.g. N years) that will memorize the language chosen by the user. That way when people visit the website with a new browser session, they get served the proper language. I have already given up on users being able to switch one page from English to French: when people will chose English or French from the menu they will be redirected to the corresponding version of the home page. Do you foresee any problems with not using a language component in the URL (whether domain or path)? (as long as one makes sure URLS don't conflict).

  • Internet is far slower in Ubuntu than Windows 7 on dual-booted machine

    - by Tim
    Edit: I'll leave the original post as-is, but after further investigation, it appears that the problem is something to do with my wi-fi card. Speeds are normal when I connect via cable. Edit 2: Problem was solved. It was something to do with the wireless card drivers. I normally use Windows 7 on my laptop and have internet speeds that are normally about 15-20 Mb/s. I have recently dual-booted with Ubuntu 12.10, and have noticed that internet speeds are drastically slower in Ubuntu. When tested, speeds range from 0.2-2 Mb/s, although occasionally being significantly faster than that or even stopping completely for short periods of time. I've also noticed that when first booting into Ubuntu, speeds start fairly fast, and drop to incredibly slow with a few seconds to a few minutes. There's still some possibility that the issue may be with my ISP, as things seem slower than usual even in Windows, but I suspect that it is related to Ubuntu, as things are far slower in Ubuntu than in Windows. I'm wondering, what could be the cause of this? Potentially relevant information: -I've dual booted before on this machine with earlier versions of Ubuntu (different ISP at the time) with no problem. ISP: Rogers (Major Canadian ISP) System info (Gateway NV53a Laptop): Operating System MS Windows 7 Home Premium 64-bit CPU AMD Phenom II N970 Caspian 45nm Technology RAM 6.00 GB Dual-Channel DDR3 @ 664MHz (9-9-9-24) Motherboard Gateway SJV51_DN (Socket S1G4) Graphics Generic PnP Monitor (1366x768@60Hz) ATI Mobility Radeon HD 4250 (Acer Incorporated [ALI]) Hard Drives 733GB TOSHIBA TOSHIBA MK7559GSXP ATA Device (SATA) Networking info: Connected through Wi-Fi Atheros AR5B97 Wireless Network A

  • Differences when Running with OutputCache managed module under ASP.NET IIS7.x with Cache-control header

    - by Shawn Cicoria
    This post is to report some differences when using MVC or IHttpHandlers if you’re attempting to set the Cache-control : max-age or s-maxage value under IIS7.x using the HttpResponse.Cache methods. [UPDATE]: 2011-3-14 – The missing piece was calling  Response.Cache.SetSlidingExpiration(true) as follows: context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); context.Response.ContentType = "image/jpeg"; context.Response.Cache.SetSlidingExpiration(true);   Under IIS7.x if you us one of the following 2 methods, you will only get a Cache-ability of “public”.  public ActionResult Image2() { MemoryStream oStream = new MemoryStream(); using (Bitmap obmp = ImageUtil.RenderImage("Respone.Cache.Setxx calls", 5, DateTime.Now)) { obmp.Save(oStream, ImageFormat.Jpeg); oStream.Position = 0; Response.Cache.SetCacheability(HttpCacheability.Public); Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); return new FileStreamResult(oStream, "image/jpeg"); } } Method 2 – which is just a plain old HttpHandler and really isn’t MVC3, but under the same MVC ASP.NET application, same result. public class image : IHttpHandler { public void ProcessRequest(HttpContext context) { using (var image = ImageUtil.RenderImage("called from IHttpHandler direct", 5, DateTime.Now)) { context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); context.Response.ContentType = "image/jpeg"; image.Save(context.Response.OutputStream, ImageFormat.Jpeg); } } } Using the following under MVC3 (I haven’t tried under earlier versions) will work by applying the OutputCacheAttribute to your Action: [OutputCache(Location = OutputCacheLocation.Any, Duration = 300)] public ActionResult Image1() { MemoryStream oStream = new MemoryStream(); using (Bitmap obmp = ImageUtil.RenderImage("called with OutputCacheAttribute", 5, DateTime.Now)) { obmp.Save(oStream, ImageFormat.Jpeg); oStream.Position = 0; return new FileStreamResult(oStream, "image/jpeg"); } } To remove the “OutputCache” module, you use the following in your web.config: <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules runAllManagedModulesForAllRequests="true"> <!--<remove name="OutputCache"/>--> </modules>

  • Frequent disconnects with oneiric server using wlan AR9285

  • Security Alert for CVE-2010-0886 and CVE-2010-0887 Released

    - by eric.maurice
    Hi, this is Eric Maurice again! Oracle just released a Security Alert to announce the availability of fixes for two vulnerabilities (CVE-2010-0886 and CVE-2010-0887) affecting Oracle Java SE and Oracle Java For Business. Both vulnerabilities only affect Java when running in a 32-bit web browser. These vulnerabilities are not present in Java running on servers or standalone Java desktop applications and do not impact any Oracle server based software. The first vulnerability (CVE-2010-0886) affects the Java Deployment Toolkit (version 6 update 10 through 19) on Windows only. The second vulnerability (CVE-2010-0887) affects the Java Plug-in (version 6 update 18 and 19) on Windows, Solaris and Linux. Both vulnerabilities may allow an attacker to run commands on the user's system with the privileges of the user, whose system may have become compromised by visiting a malicious web site. Oracle rated the severity of both vulnerabilities with a CVSS Base Score of 10.0 because many Windows users grant themselves administrative privileges. However, on other platforms, or for Windows users with limited privileges, the CVSS Base Score is only 7.5, because a successful exploitation of these vulnerabilities cannot result in a full compromise of the affected system. Users can quickly determine if they are running vulnerable versions of Java by pointing their browser to http://www.java.com/en/download/help/testvm.xml. Java SE users can visit http://www.java.com and download the most recent release of Java SE to address these vulnerabilities. Because of the criticality of these vulnerabilities, and the publicity they received as a result of their disclosure before the availability of a fix, Oracle recommends that all customers and Java users update their Java installation to the most recent version (6 update 20). For More Information: The advisory for the Security Alert for CVE-2010-0886 and CVE-2010-0887 is located at http://www.oracle.com/technology/deploy/security/alerts/alert-cve-2010-0886.html

  • Tip: Recording Non-Maximized Applications in UPK

    - by Marc Santosusso
    Have you ever wanted to record an application that would not maximize, or an application that would look strange maximized? Or perhaps your Windows Desktop has become cluttered with icons and you don't want to capture the clutter in your recordings. Here's a tip that will help: create a background for your recording. Create a blank HTML file with a black background in your favorite HTML editor. Or download this sample file: UPK_Recording_Background.html (right click to save). If you would prefer a different color background in the sample file, open it in Notepad and change “#000” to a different HTML color. Open UPK_Recording_Background.html in its own web browser window. Press F11 to make the web browser window full screen. This should give you a completely black screen. (This works great in modern versions of the most popular browsers. I successfully used Firefox 15, Chrome 22, and IE 9. Open or switch to the desired application so that it sits on top of the full screen browser window. If the application you are recording is also in a browser, it is important that it be in a separate browser window from the UPK_Recording_Background.html. Record your topic normally. The above steps create a recording background using an HTML file and a web browser. This is just one method, for instance you could do the same thing with an image editor and an image viewer with a full screen view. Now you can record a non-maximized application without a distracting background. I hope you find this to be a helpful tip. Let us know what you think in the comments.

  • Oracle Java Embedded Client 1.1 Released

    - by Roger Brinkley
    Yesterday an update release of Oracle Java Embedded Client (OJEC) 1.1 quietly slipped out door for general availability. Until last year it was pretty difficult to get your hands on either a Connected Limited Device Configuration (CLDC) for small devices or a Connected Device Configuration (CDC) for medium devices java implementation without a substantial initial commitment. But with the the release of OJWC (CLDC) and OJEC (CDC) last year that has changed. OJEC 1.1 is a binary distribution designed for installation on medium configurations which is a mid range processor requiring a  slow startup time, seamless upgrades, in a cost sensitive hardware environment  anywhere from 3.5mb to 8 mb. There are headless as well as headed versions available. It is intended for devices, such as Blu-­-ray Disc players, set-­-top boxes, residential gateways,VOIP phones, and similar. From a software point of view, OJEC is the Java runtime platform implementation of Connected Device Configuration (CDC v1.1, JSR-­-218), Foundation Profile (FP v1.1, JSR-­-219), and Personal Basis Profile (PBP v1.1, JSR-­-217)  and includes optional packages RMI (JSR 66), JDBC (JSR 169) and XML API for Java ME (JSR 280), and Java TV (JSR-­-927). New to this release is support for the XML API (JSR 280) and a number of bug fixes and performance enhancements, including an improved Just-in-Time (JIT) compilation for the x86 chipset architecture. The platforms supported include ArmV5, ArmV6/ArmV7, MIPS 32 74K, and X86 in headless mode. For embedded developers there are number of advantages to using Java and if you have shied away from the JavaME edition in the past I would encourage you to look into the updated version of OJEC 1.1.

  • Use Those Schemas, People!

    - by BuckWoody
    Database Schemas are just containers – they aren’t users or anything else – think of a sub-directory on the hard drive. In early versions of SQL Server we “hid” schemas, placing all objects under “dbo”, which gave the erroneous perception that Schemas are users. In SQL Server 2005, we “un-hid” or re-introduced schemas within the database. Users can have a default schema (a place where their new objects go), you can add new schemas and transfer objects between them, and they have many other benefits. But I still see a lot of applications, developed by shops I know as well as vendors, that don’t make use of a Schema. Everything is piled under dbo. I completely understand this – since permissions can be granted to a schema, they feel a lot like a user, so it’s just easier not to worry about both users and schemas when you create a database. But if you’ll use them properly you can make your application more understandable and portable. You should at least take a few minutes and read more about them – you owe it to your users: http://msdn.microsoft.com/en-us/library/ms190387.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Data Structure for Small Number of Agents in a Relatively Big 2D World

    - by Seçkin Savasçi
    I'm working on a project where we will implement a kind of world simulation where there is a square 2D world. Agents live on this world and make decisions like moving or replicating themselves based on their neighbor cells(world=grid) and some extra parameters(which are not based on the state of the world). I'm looking for a data structure to implement such a project. My concerns are : I will implement this 3 times: sequential, using OpenMP, using MPI. So if I can use the same structure that will be quite good. The first thing comes up is keeping a 2D array for the world and storing agent references in it. And simulate the world for each time slice by checking every cell in each iteration and further processing if an agents is found in the cell. The downside is what if I have 1000x1000 world and only 5 agents in it. It will be an overkill for both sequential and parallel versions to check each cell and look for possible agents in them. I can use quadtree and store agents in it, but then how can I get the information about neighbor cells then? Please let me know if I should elaborate more.

  • Removed Java replaced with newest "Sun Java", disc won't boot, and won't let me re-install grub using boot repair disc

    - by Al Rowe
    Had a minor problem with my Stock market platform. Set-up screen would freeze program. Called their tech support, got their "Linux guy", who advised remove all Java and replace, not with synaptic version, but newest Sun Java. After removing, computer auto rebooted, and went to blue mem-test screen. Showed no errors, but couldn't get back in. Tried two versions of boot repair disc from iso (checked md5sum, showed good.), but fix aborted, giving apt-error detected. Opened a terminal and typed (or copy/paste): sudo chroot "/mnt/boot-sav/sda1" apt-get -f install. My system is Ubuntu 12.04. Had a few very minor issues from install, all fixed. Also added some of my favorite gnome tricks just to make life easier, but none that could have caused this. Added script to add shortcuts to desktop, open terminal in any menu from inside it, access root terminal, etc. System was firewalled and using avast antivirus (o.k., I'm paranoid. Used to do Windows sys-op and security.) But relative newbie to Linux.

  • Are the Ubuntu ISO images updated From release .ubuntu.com

    - by tijybba
    Just got idea from this(may not be related though) question however. Are the ISO images from the official site updated with updates in Core Ubuntu system , like Kernel Updates , desktop Environment Updates(unity), i mean Updates of BASE system including X-org, Office suite, Package Manager , Update manager or Gnome Base Modules, those released in update Branches like precise-Updates branch. The reason i am asking this is , if i download the ISO image of Ubuntu 12.04 Say after two or three months from release , i have to do an update of approximately 200~300 MB's size. So why are these ISO images not updated to recent updates, i am aware that all of the components are not updated at the same time , but let's say after One month from actual release ( Both LTS and normal releases), the updated components can be added to form a Updated ISO in regular intervals, which provides new users to use latest versions and features with improved stability and less bandwidth Consumption. I am not mentioning the idea of comparison to Rolling Release , or External PPA's added updates , and neither Netinstal but the ISO of updated Packages .This can be provided as optional download. Since my question is within the boundary of Official updates releases so stability could not be the reason. I guess there are custom packagers out there , but having an official option would be better. It helps in distributing Newest ISO OS which impresses a lot new users , since it makes availability of newer features and a faster system ofcourse. Another reason of asking this is here. Edit: Since almost all new (Desktop) users download the Default ISO's having one or few issue , which may have been corrected in following updates. But most of new laptop users i encountered gave up because of it , so should i suggest ,for laptop not listed on Certified H/W list , to try daily Builds , if needed.
