How to Install a Wireless Card in Linux Using Windows Drivers

- by Justin Garrison

Linux has come a long way with hardware support, but if you have a wireless card that still does not have native Linux drivers you might be able to get the card working with a Windows driver and ndiswrapper. Using a Windows driver inside of Linux may also give you faster transfer rates or better encryption support depending on your wireless card. If your wireless card is working, it is not recommended to install the Windows driver just for fun because it could cause a conflict with the native Linux driver Latest Features How-To Geek ETC How To Make Hundreds of Complex Photo Edits in Seconds With Photoshop Actions How to Enable User-Specific Wireless Networks in Windows 7 How to Use Google Chrome as Your Default PDF Reader (the Easy Way) How To Remove People and Objects From Photographs In Photoshop Ask How-To Geek: How Can I Monitor My Bandwidth Usage?

Firefox 5 : les premières pistes de réflexions mises en ligne par Mozilla

Firefox 5 : les premières pistes de réflexions Mises en ligne par Mozilla Firefox 4 n'est pas encore sorti que Mozilla et la communauté travaillent déjà sur Firefox 5. La fondation vient de mettre en ligne des captures d'écran et des pistes de réflexions issues de ses premiers travaux. On y a apprend tout d'abord que Firefox 5 devrait donner un contrôle total à l'utilisateur sur ses extensions. Une nouvelle page dédiée permettra d'activer ou de désactiver chacun d'entre eux. Sur les captures, il n'est pas clair cependant que ce système ne s'adresse pas plutôt aux plug-ins. La liste de contrôle sera séparée en deux pour permettre de visualiser les comp...

Firefox : Mozilla étudie de près les lignes de code « miracles » qui diminuent le temps de démarrage et explique les limites de ce patch

Firefox : Mozilla étudie la possibilité d'intégrer les lignes de code « miracles » Qui diminuent le temps de démarrage et explique les limites de ce patch Un des reproches les plus importants fait à Firefox, notamment face à Chrome, est sa lenteur au démarrage. Un point sur lequel la fondation Mozilla travaille très sérieusement et que les betas succesives de Firefox 4 ont amélioré. Pas assez, cependant, au goût de certains, d'autant plus que le mois dernier, Tara Glek, un des employés de Mozilla, a publié à titre personnel une vingtaine de lignes de code censées pouvoir diviser par deux ce temps de démarrage.

Gartner prévoit une forte croissance de la Business Intelligence sur 2011, et un changement en profondeur des solutions

Gartner prévoit une croissance de 9,7 % du marché de la Business Intelligence Sur 2011, et un changement en profondeur des solutions Le cabinet d'études Gartner prévoit une croissance de 9,7 % du marché de la Business Intelligence (BI) sur 2011. Une croissance qui devrait ensuite se poursuivre jusqu'en 2014, sur une rythme légèrement inférieur. La BI devrait donc être un des secteurs du marché du logiciel qui progresse le plus rapidement, en dépit du ralentissement économique. « Les organisations continuent leurs projets de BI », explique Ian Bertram, vice- président de Gartner, et ce pour une raison simple, « elles espèrent qu'ils leur permettront de réduire leurs coûts, d'amél...

SQLBits just got bigger

- by simonsabin

If you’ve had your ear to the twitter ground you will have seen that the provisional agenda for SQLBIts has been put online. http:// sqlbits .com/information/agenda.aspx You will also notice that we have put on a little weight. Yes we’ve eaten too many sessions meaning we have to extend to another room from the 10:50 onwards. This means you have 6 sessions to choose from rather than the normal 5. Whats more to get even more sessions in we’ve looked at those that have registered and decided they are...(read more)

How are Reads Distributed in a Workload

- by Bill Graziano

People have uploaded nearly one millions rows of trace data to TraceTune. That’s enough data to start to look at the results in aggregate. The first thing I want to look at is logical reads. This is the easiest metric to identify and fix. When you upload a trace, I rank each statement based on the total number of logical reads. I also calculate each statement’s percentage of the total logical reads. I do the same thing for CPU, duration and logical writes. When you view a statement you can see all the details like this: This single statement consumed 61.4% of the total logical reads on the system while we were tracing it. I also wanted to see the distribution of reads across statements. That graph looks like this: On average, the highest ranked statement consumed just under 50% of the reads on the system. When I tune a system, I’m usually starting in one of two modes: this “piece” is slow or the whole system is slow. If a given piece (screen, report, query, etc.) is slow you can usually find the specific statements behind it and tune it. You can make that individual piece faster but you may not affect the whole system. When you’re trying to speed up an entire server you need to identity those queries that are using the most disk resources in aggregate. Fixing those will make them faster and it will leave more disk throughput for the rest of the queries. Here are some of the things I’ve learned querying this data: The highest ranked query averages just under 50% of the total reads on the system. The top 3 ranked queries average 73% of the total reads on the system. The top 10 ranked queries average 91% of the total reads on the system. Remember these are averages across all the traces that have been uploaded. And I’m guessing that people mainly upload traces where there are performance problems so your mileage may vary. I also learned that slow queries aren’t the problem. Before I wrote ClearTrace I used to identify queries by filtering on high logical reads using Profiler. That picked out individual queries but those rarely ran often enough to put a large load on the system. If you look at the execution count by rank you’d see that the highest ranked queries also have the highest execution counts. The graph would look very similar to the one above but flatter. These queries don’t look that bad individually but run so often that they hog the disk capacity. The take away from all this is that you really should be tuning the top 10 queries if you want to make your system faster. Tuning individually slow queries will help those specific queries but won’t have much impact on the system as a whole.

EJB Persist On Master Child Relationship

- by deepak.siddappa(at)oracle.com

Let us take scenario where in users wants to persist master child relationship. Here will have two tables dept, emp (using Scott Schema) which are having master child relation.Model Diagram: Here in the above model diagram, Dept is the Master table and Emp is child table and Dept is related to emp by one to n relationship. Lets assume we need to make new entries in emp table using EJB persist method. Create a Emp form manually dropping the fields, where deptno will be dropped as Single Selection -> ADF Select One Choice (which is a foreign key in emp table) from deptFindAll DC. Make sure to bind all field variables in backing bean.Employee Form:Once the Emp form created, If the persistEmp() method is used to commit the record this will persist all the Emp fields into emp table except deptno, because the deptno will be passed as a Object reference in persistEmp method (Its foreign key reference). So directly deptno can't be passed to the persistEmp method instead deptno should be explicitly set to the emp object, then the persist will save the deptno to the emp table.Below solution is one way of work around to achieve this scenario -Create a method in sessionBean for adding emp records and expose this method in DataControl. For Ex: Here in the below code 'em" is a EntityManager. private EntityManager em - will be member variable in sessionEJBBeanpublic void addEmpRecord(String ename, String job, BigDecimal deptno) { Emp emp = new Emp(); emp.setEname(ename); emp.setJob(job); //setting the deptno explicitly Dept dept = new Dept(); dept.setDeptno(deptno); //passing the dept object emp.setDept(dept); //persist the emp object data to Emp table em.persist(emp); }From DataControl palette Drop addEmpRecord as Method ADF button, In Edit action binding window enter the parameter values which are binded in backing bean. For Ex: If the name deptno textfield is binded with "deptno" variable in backing bean, then El Expression Builder pass value as "#{backingbean.deptno.value}"Binding:

How to determine if a programming language is verbose or terse?

- by sunpech

Programming languages can often be described as verbose or terse. From my understanding, a verbose language is easy to read and understand, while a terse language is concise and neat, but more difficult to read. Should there be other things to consider in the definitions? It seems much of the popular programming languages of today are verbose, and these terms two terms are only used to describe a language as being more or less, relative to than another language. How do we determine if a programming language is more verbose/terse over another? Example: Is C# more verbose than Java?

Should I go back to the same company ?

- by vinoth

Hi , I quit the company I was working for(lets call it XYZ) and joined another company . When I quit the company I had very little Software development experience . I thought the rest of the world is a better place . So I complained about the word quality and all that while i quit . One year has taught me a lot of things and I feel XYZ is a much better place (in terms of freedom and decision making in work) . Is it ok to go back ? I am thinking a lot whether to go or not because I quit complaining the nature of work and now I am going back for the same thing . Also I am kind of not very sure to go to other places because , the work and quality are not predictable (I am might become disappointed again ) . Have any of guys been in the same situation before ?

Enterprise VS Regular corporate developer

- by Rick Ratayczak

Ok, I "almost" lost a job offer because I "didn't have enough experience as an enterprise software engineer". I've been a programmer for over 16 years, and the last 12-14 professionally, at companies big and small. So this made me think of this question: What's the difference between a software engineer and an enterprise software engineer? Is there really a difference between software architecture and enterprise architecture? BTW: I try to do what every other GOOD software programmer does, like architecture, tdd, SDLC, etc.

Weekly technology meeting?

- by Mag20

I am thinking of introducing weekly technology meeting where programmers working on the same project can discuss things like: current status of the project on technical side technology backlog. Things that we may have skipped because of deadlines but now coming back to bite us. technology constraints that are limiting developers from being productive new and emerging technologies that may apply to the project Basically looking at the project from programmer's perspective, not the business side. - What would be some good guidelines for a meeting like this? How long should the meeting last? Is weekly too often? Should we time-limit each topic? What kinda of topics are good for a meeting like this and which ones are bad? Is 10 people too many? ...

Avoid GPL violation by moving library out of process

- by Andrey

Assume there is a library that is licensed under GPL. I want to use it is closed source project. I do following: Create small wrapper application around that GPL library that listens to socket, parse messages and call GPL library. Then returns results back. Release it's sources (to comply with GPL) Create client for this wrapper in my main application and don't release sources. I know that this adds huge overhead compared to static/dynamic linking, but I am interested in theoretical way.

How to avoid mediocre CV.

- by QriousCat

Though in every project we (testers) face different set challenges, when it comes to CV, more or less we have same responsibilities. For example responsibilities like understanding requirements, preparing and executing test cases, creating defects, liaising with dev, BA teams will be repeated for every project we involve. If we keep writing same responsibilities for every role, CV becomes mediocre and a yarn. In fact most of the testing resumes I have come across are like that. How do I avoid repetition of responsibilities in my resume and make it more interesting? If this is not the correct forum for this question let me know. Thanks in advance for your suggestions.

Best practices for using namespaces in C++.

- by Dima

I have read Uncle Bob's Clean Code a few months ago, and it has had a profound impact on the way I write code. Even if it seemed like he was repeating things that every programmer should know, putting them all together and putting them into practice does result in much cleaner code. In particular, I found breaking up large functions into many tiny functions, and breaking up large classes into many tiny classes to be incredibly useful. Now for the question. The book's examples are all in Java, while I have been working in C++ for the past several years. How would the ideas in Clean Code extend to the use of namespaces, which do not exist in Java? (Yes, I know about the Java packages, but it is not really the same.) Does it make sense to apply the idea of creating many tiny entities, each with a clearly define responsibility, to namespaces? Should a small group of related classes always be wrapped in a namespace? Is this the way to manage the complexity of having lots of tiny classes, or would the cost of managing lots of namespaces be prohibitive?

Creating an expandable, cross-platform compatible program "core".

- by Thomas Clayson

Hi there. Basically the brief is relatively simple. We need to create a program core. An engine that will power all sorts of programs with a large number of distinct potential applications and deployments. The core will be an analytics and algorithmic processor which will essentially take user-specific input and output scenarios based on the information it gets, whilst recording this information for reporting. It needs to be cross platform compatible. Something that can have platform specific layers put on top which can interface with the core. It also needs to be able to be expandable, for instance, modular with developers being able to write "add-ons" or "extensions" which can alter the function of the end program and can use the core to its full extent. (For instance, a good example of what I'm looking to create is a browser. It has its main core, the web-kit engine, for instance, and then on top of this is has a platform-specific GUI and can also have add-ons and extensions which can change the behavior of the program.) Our problem is that the extensions need to interface directly with the main core and expand/alter that functionality rather than the platform specific "layer". So, given that I have no experience in this whatsoever (I have a PHP background and recently objective-c), where should I start, and is there any knowledge/wisdom you can impart on me please? Thanks for all the help and advice you can give me. :) If you need any more explanation just ask. At the moment its in the very early stages of development, so we're just researching all possible routes of development. Thanks a lot

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...

is OpenID really that bad?

- by DoPPler

I have seen this question on Quora where lots of people seem to agree that OpenID is bad, even going as far as stating that: OpenID is the worst possible "solution" I have ever seen in my entire life to a problem that most people don't really have Then I've seen articles and tweets referencing that question saying that OpenID has lost, and Facebook won. It's sad to read as I quite like the OpenID (or at least idea behind it). I literally hate getting yet another login/password for page (I'll forget it anyway) - it's a pretty serious issue for me and I know lots of people with the same problem. Thus I thought that OpenId is a great solution but I'm not sure anymore. So the question is should I still bother to implement OpenID or it's not worth it? What is the most robust and convenient (from the user perspective) way to identify and authenticate an user?
