  • Change login screen to gnome-shell login

    - by Dr_Bunsen
    I was just goofing around in a vm to test what would happen if I purgen unity: sudo apt-get remove --purge unity* I found that I get an startup error, but when I proceed, I got this awesome login screen: It has an sexy effect and is just the gnome style my whole pc has got. So can any one please tell me how I change the default login screen program without having to bother clicking "fix this error" on every boot? Thanks in advance. [edit] This is the error I get, and the only option that works is the, run in low settings for one session.

  • The death of Kodak digital

    - by Ken Hortsch
    Months ago Kodak announced that it was discontinuing its digital video to focus on “significant opportunities for profitable growth”.  Three years ago I picked up the little Kodak Zi6 (pronounced Zix) for the kids for Christmas.  It is an HD pocket video camera with a nice 3” LCD all built into a something a bit longer than an deck of cards.  It is low tech and great!  The kids have had a ball with it, and for around $100 it was perfect.  It comes with 2 AA rechargeable batteries and the recharger.  You can add an SD card, but don’t need to, and the USB is not a cable but a pop-out dongle so everything is right in the one package.  Too many companies look for the next big thing and fail to see the stuff that is good enough, and right in front of their eyes.

  • Changing the Game: Why Oracle is in the IT Operations Management Business

Oracle is a premier sponsor of this annual event, which brings together IT executives for several days of high level talks about the state of operational management of enterprise IT. This year, Sushil Kumar, VP Product Strategy and Business Development for Oracle’s Systems & Applications Management, will be presenting on the transformation in IT Operations required to support enterprise cloud computing. IT Operations transformation is an important subject, because year after year, we hear essentially the same refrain – large enterprises spend an average of two-thirds (67%!) of their IT resources (budget, energy, time, people, etc.) on running the business, with far too little left over to spend on growing and transforming the business (which is what the business actually needs and wants). In the thirtieth year of the distributed computing revolution (give or take, depending on how you count it), it’s amazing that we have still not moved the needle on the single biggest component of enterprise IT resource utilization. Oracle is in the IT Operations Management business because when management is engineered together with the technology under management, the resulting efficiency gains can be truly staggering. To put it simply – what if you could turn that 67% of IT resources spent on running the business into 50%? Or 40%? Imagine what you could do with those resources. It’s now not just possible, but happening. This seems like a simple idea, but it is a radical change from “business as usual” in enterprise IT Operations. For the last thirty years, management has been a bolted-on afterthought – we pick and deploy our technology, then figure out how to manage it. This pervasive dysfunction is a broken cycle that guarantees high ongoing operating costs and low agility. If we want to break the cycle, we need to take a more tightly-coupled approach. As a complete applications-to-disk platform provider, Oracle is engineering management together with technology across our stack and hooking that on-premise management up live to My Oracle Support. Let’s examine the results with just one piece of the Oracle stack – the Oracle Database. Oracle began this journey with the Oracle Database 9i many years ago with the introduction of low-impact instrumentation in the database kernel (“tell me what’s wrong”) and through Database 10g, 11g and 11gR2 has successively added integrated advisory (“tell me how to fix what’s wrong”) and lifecycle management and automated self-tuning (“fix it for me, and do it on an ongoing basis for all my assets”). When enterprises take advantage of this tight-coupling, the results are game-changing. Consider the following (for a full list of public references, visit this link): British Telecom improved database provisioning time 1000% (from weeks to minutes) which allows them to provide a new DBaaS service to their internal customers with no additional resources Cerner Corporation Saved $9.5 million in CapEx and OpEx AND launched a brand-new cloud business at the same time Vodafone Group plc improved response times 50% and reduced maintenance planning times 50-60% while serving 391 million registered mobile customers Or the recent Database Manageability and Productivity Cost Comparisons: Oracle Database 11g Release 2 vs. SAP Sybase ASE 15.7, Microsoft SQL Server 2008 R2 and IBM DB2 9.7 as conducted by independent analyst firm ORC. In later entries, we’ll discuss similar results across other portions of the Oracle stack and how these efficiency gains are required to achieve the agility benefits of Enterprise Cloud.

  • How do I convince my boss to come here and see how "good" companies are doing?

    - by Vimvq1987
    My company is bad, I admit it. Inefficient project management, very low quality code, ... I won't get into it. It's partly based on our country's culture, but mostly because our boss is not looking at how good companies are actually going about producing good software/service. I want to bring my boss here, so he can see these things, to convince him to create a better development place for us. How can I do that? Thank you so much. Ps: If I fail to do this, you know, I'm thinking seriously of leaving

  • SQL Server: collect values in an aggregation temporarily and reuse in the same query

    - by Erwin Brandstetter
    How do I accumulate values in t-SQL? AFAIK there is no ARRAY type. I want to reuse the values like demonstrated in this PostgreSQL example using array_agg(). SELECT a[1] || a[i] AS foo ,a[2] || a[5] AS bar -- assuming we have >= 5 rows for simplicity FROM ( SELECT array_agg(text_col ORDER BY text_col) AS a ,count(*)::int4 AS i FROM tbl WHERE id between 10 AND 100 ) x How would I best solve this with t-SQL? Best I could come up with are two CTE and subselects: ;WITH x AS ( SELECT row_number() OVER (ORDER BY name) AS rn ,name AS a FROM #t WHERE id between 10 AND 100 ), i AS ( SELECT count(*) AS i FROM x ) SELECT (SELECT a FROM x WHERE rn = 1) + (SELECT a FROM x WHERE rn = i) AS foo ,(SELECT a FROM x WHERE rn = 2) + (SELECT a FROM x WHERE rn = 5) AS bar FROM i Test setup: CREATE TABLE #t( id INT PRIMARY KEY ,name NVARCHAR(100)) INSERT INTO #t VALUES (3 , 'John') ,(5 , 'Mary') ,(8 , 'Michael') ,(13, 'Steve') ,(21, 'Jack') ,(34, 'Pete') ,(57, 'Ami') ,(88, 'Bob') Is there a simpler way?

  • SQLite with two python processes accessing it: one reading, one writing

    - by BBnyc
    I'm developing a small system with two components: one polls data from an internet resource and translates it into sql data to persist it locally; the second one reads that sql data from the local instance and serves it via json and a restful api. I was originally planning to persist the data with postgresql, but because the application will have a very low-volume of data to store and traffic to serve, I thought that was overkill. Is SQLite up to the job? I love the idea of the small footprint and no need to maintain yet another sql server for this one task, but am concerned about concurrency. It seems that with write ahead logging enabled, concurrently reading and writing a SQLite database can happen without locking either process out of the database. Can a single SQLite instance sustain two concurrent processes accessing it, if only one reads and the other writes? I started writing the code but was wondering if this is a misapplication of SQLite.

  • Developing a live video-streaming website

    - by cawecoy
    I'm a computer science student and know a little about some technology to start developing my website, like PHP, RubyOnRails and Python, and MySQL and PostgreSQL for Database. I need to know what are the best (secure, stable, low-price, etc) to get started, based on my business information: My website will be a live video-streaming one, similar to livestream.com We need to provide a secure service for our customers. They need to have a page to create and configure their own Live-Streaming-Videos, get statistics, etc. We work with Wowza Media Server ruuning on an Apache Server In addition, I would like to know some good practices for this kind of website development, as I am new to this. Thanks in advance!

  • Highlight Read-Along Text (in a storybook type app for iPhone)

    - by outtoplayinc
    I love this feature (well, my son loves it), and I would like to implement it in a kid's book app I am doing for iPhone, but I'm clueless where to begin. I'm using Cocos2d for all the animated sprite/transition stuff, but I'm not sure how to approach highlighting text as it is narrated. Example: "Jack and Jill, drank their fill, and were too drunk to go for water." As the text is narrated (.mp3 plays on each page), the text would be highlighted. I considered investigating Core animation, but I"m more familiar with Cocs2d at this point (tenuously at best). If someone has a clue, I'd really appreciate it. Brendang

  • Coding style advice? [closed]

    - by user1064918
    I'm a newly grad. I've got a lot of complaints from my supervisor at work during code-review sessions with regard to my coding style (Surprise!). I don't know if it's just him being cranky or my style is really that annoying to read. I come from the low-level language world (assembly, mostly), so I've been taught to use bitwise ops and all the cool tricks to do math whenever possible. I also have the habits of doing some other things that've been regarded as "too excessively dense to read". So I'm hoping to get some feedback from any experienced programmers! :) Also how should I justify between code performance and readability? Thanks!!

  • Consuming JSON stream into AWS Database on the cheap

    - by wjl
    I'm working on a project that needs to consume a JSON stream (approximately 1MB / minute), and parse and insert objects into a database. Amazon's DynamoDB or SimpleDB seem like attractive options for this. Is there a web service that can run a very simple script to eat the data and put it in a database? I could use a worker on Heroku or Elastic Beanstalk, or even pure EC2, but I'd like to find a service that's much cheaper, due to the very low amount of bandwidth and CPU required. (Sorry for the crappy tags. I'm not even sure where to categorize this question.)

  • fix a broken ubuntu installation from pendrive

    - by interstar
    Something went wrong in the upgrade of my Ubuntu 13.04 to 13.10 The upgrade basically crashed halfway through. On booting I was thrown into a maintainence screen. I found some online instructions for fixing with the package manager ... Which seemed to do a lot of setting up. But then crashed saying package is in a bad inconsistent state. Now I'm in a position where Ubuntu starts again, but goes into a low-res screen and there's no WiFi. I have no Ethernet cable connection but I did download the 13.10 iso on another machine and put it on a pen drive. So I'd like to know there's a way of asking the machine from inside Ubuntu to redo its upgrade from the data on the pendrive rather than WiFi. Is this possible? Cheers Phil

  • Decrease mouse sensitivity below the standard limit.

    - by Bruce Connor
    I've got a USB mouse attached to my Ubuntu notebook. This mouse is (unfortunately) really sensitive, and so it sometimes gets hard to hit small icons with the mouse pointer. This is really a hardware issue, it's not a bug and it's not Ubuntu's/gnome's fault. Still, I would very much like to this issue through software (solving through hardware would imply buying a new mouse). Back in Windows, if I set the sensitivity as really low it was comfortable enough. In Ubuntu, even the lowest sensitivity and acceleration available (in the SystemPrerencesMouse menu) is still frustrating. How can I decrease it below the default minimum? I tried xset, but it seems xset only deals with acceleration and threshold, but not actual sensitivity.

  • Future-proofing myself when learning to program.

    - by Chris Bridgett
    I want to learn to program in a 'future-proof' manner, if you like. Whilst Windows dominates the desktop OS marketplace (for now), obviously there is a lot of value in learning its languages/frameworks/API's and so on - this might be subject to change as new devices emerge or Windows shoots itself in the foot (over-friendly previews of Windows 8 don't look too appealing...). Would I be right in thinking that having a solid knowledge of C/C++ for back-end logic/low level programming and the like, combined with an extremely portable language like Java for GUI's and so on, would be a good basis for software development that will prove useful on the most amount of systems? - I'm talking desktop PC's, tablets, phones.

  • How to maximize Java resources for gaming?

    - by Keidax
    I notice that when I play Minecraft, my CPU usage is only around 15 to 20 percent, at most. Is it possible to force my computer to allocate as much RAM, CPU time, etc. to the game, in order to get the best experience possible? Or, is the low CPU usage due to limitations in the JVM or the game code itself? I have OptiFine installed, and I've already tried using renice to change the process priority and -Xmx to allocate more memory to Java. What else can I do?

  • In-Memory OLTP Sample for SQL Server 2014 RTM

    - by Damian
    I have just found a very good resource about Hekaton (In-memory OLTP feature in the SQL Server 2014). On the Codeplex site you can find the newest Hekaton samples - https://msftdbprodsamples.codeplex.com/releases/view/114491. The latest samples we have were related to the CTP2 version but the newest will work with the RTM version.There are some issues fixed you might find if you tried to run the previous samples on the RTM version:Update (Apr 28, 2014): Fixed an issue where the isolation level for sample stored procedures demonstrating integrity checks was too low. The transaction isolation level for the following stored procedures was updated: Sales.uspInsertSpecialOfferProductinmem, Sales.uspDeleteSpecialOfferinmem, Production.uspInsertProductinmem, and Production.uspDeleteProductinmem.

  • Microsoft and Joyent Announce Node.js Windows Port

    With the Node.js command line tool, developers can type ?node my_app.js.' to run JavaScript programs. It gives developers a JavaScript application programming interface (API) supplies access for the network and file system as well. One instance where Node.js often comes in handy is in the creation of scalable networked programs that emphasize high concurrency and low response times. Developers who wish to use Node.js use on Windows at this time must do so running a virtual machine with Linux.

  • Splitting up revenue among development team members on Apple's app store

    - by itaiferber
    A friend and I have started developing an app to put on Apple's app store. Development is going fine, but thinking ahead, we're trying to come up with an easy way to share any revenue coming from our efforts. The app store allows you to deposit your revenue into a single bank account, but there's no easy way to split revenue among several people. How do (small) dev teams split up revenue on their products, on, and off the app store? As far as I can tell, banks don't offer an easy way to automatically split the balance on an account 50-50 (or any other percentage, for that matter), especially on a regular basis. So how do teams deal with this? We're not incorporated, and we don't have an official business set up. We're considering depositing all the money into one of our accounts and manually transferring half the money to the other person, but this isn't sustainable over long periods of time. Is there a low-cost, sustainable, automatic process for handling these finances?

  • SEO and Spelling mistakes in keyword

    - by Sushil
    I am about to register a domain name (suppose) someone.com (with proper spelling), in mind targeting the keyword "SOMEONE". But then I discovered on 'google keyword research tool' that not this but a typo "SOME1" seems to be more popular and people search this significantly more often than the proper keyword. And luckily someone.com and some1.com both are available. I understand that I can register both the domains, but I don't know on which should I keep my website and redirect the other one. Should I make the typo "some1.com" my base site? But that's a typo. P.S., my site has a totally relevant content and not just keyword targeted worthless site. What do you guys suggest? I am confused. How would that affect my SEO ranking?? EDIT: Because the competition for the keyword I am targeting is fairly low, I think nevertheless whatever domain I choose, it will appear on the search engine first page.

  • What is the most effective way to add functionality to unfamiliar, structurally unsound code?

    - by Coder
    This is probably something everyone has to face during the development sooner or later. You have an existing code written by someone else, and you have to extend it to work under new requirements. Sometimes it's simple, but sometimes the modules have medium to high coupling and medium to low cohesion, so the moment you start touching anything, everything breaks. And you don't feel that it's fixed correctly when you get the new and old scenarios working again. One approach would be to write tests, but in reality, in all cases I've seen, that was pretty much impossible (reliance on GUI, missing specifications, threading, complex dependencies and hierarchies, deadlines, etc). So everything sort of falls back to good ol' cowboy coding approach. But I refuse to believe there is no other systematic way that would make everything easier. Does anyone know a better approach, or the name of the methodology that should be used in such cases?

  • This not having job, is driving me nuts!

    - by Ratman21
    I had two jobs lined up (temporary but, hey they pay), one of which was in IT. A very low paying IT job for only 30 hours a week and only 3 weeks. At a large high tech company and a government (a not in my field job) temporary, paying a bit more, for little longer and for up to 40 hours a week. I was going to happily work my little self raged for the next 3 weeks. Guess what, the IT job fell thru and I now feel so let down. This I felt was my chance to get back in to IT, even if it was only for few weeks and maybe get note-us as hard working IT guy. I still have the other job but, let me add that there is no chance that it will turn in to something longer (I have been told that point blank). As I said this is nuts.

  • Get the closest number

    - by user183089
    Hi, i am implementing a little Black Jack game in C# and i have the following problem calculating the player's hand value. the problem is Ace may have value of 1 or 11 so if the players has three cards and one Ace if the sum of the cards is <= 10 Ace will have value of 11(Sorry for who doesn't know the scope of the game is to reach 21 with the sum of the cards) Other way value of 1 Up to here is easy Now lets assume i do not know how many Aces the player has got and the game is implemented giving the possibility to the dealer to use more than one deck of cards. the user may have in one hand even 5,6,7,8 ... aces. What is the best way(possibly using Linq) to evaluate all the aces the player has got to get the closest combination to 21 (in addition tot he other cards)? I hope i have been clear thanks for your help.

  • Cannot Adjust Brightness on Acer Aspire 5332

    - by Laurens
    I recently installed Ubuntu 12.04 with the Windows installer. It appears to be running fine, however the screen is extremely dull and I don't appear to be able to adjust the brightness... I entered the settings and tried to play with the brightness there, however there is no change in apparent brightness whether it is set to high or low on the menu. I am using an Acer Aspire 5332 with Windows 7 Ultimate. It is worth noting that the original keyboard from the laptop no longer works, so I am using a USB keyboard (meaning that I don't have access to the Fn keys)...

  • Problem with Free sapce

    I was zeroing out the free space on my Ubuntu 12.04 using sfill, when the command stopped responding and I had to reboot the machine. Now, the system says that it has no space left, and that it is running in low graphics mode. Before this happened, I had nearly 500 gig free. df says there are 0 bytes free. df -i reports only 2% of INODES used. I've run fsck and it didn't resolve the issue. What can I do to resolve the issue?

  • How can I reply to email by sending a delivery failure message?

    - by wau
    Occasionally, I receive unwanted emails, particularly low-volume spam, or email messages falsely addressed to me (possibly due to typos). I don't want to spend the energy to write a personal message, but I do want to let the sender know that the message never arrived at its destination, and that resending it will be useless. In my opinion, a delivery error message to the sender will fill that need. So, the question is if there is an easy way to send error messages back to the sender. Is there any email client out there which supports sending delivery failure messages as a reply to incoming email -- ideally in one click? (Or, which can be configured to do so?) Alternatively, what is the best way to set up an environment that allows me to send delivery failure messages without too much effort per message sent?
