• Performance Tune IBM DB2 z/OS Applications using Resource Constraint Analysis

  For the DB2 for z/OS professional the two most common systems tuning scenarios are tuning a DB2 data sharing group or tuning a series of application SQL statements. The data sharing group environment can involve multiple hardware installations and many other cross-system features and functions such as coupling facilities and management policies. Resource constraint analysis is a useful tool in both situations.

• Compiz Cube bindings don't seem to work

  - by Giancarlo Palmiotti

  I have been trying to get the 3D Cube to work however, despite setting a combination for various keys from S1 (VAIO/VAIOFW) to F7 to no avail. What is "Primary" and I am not going to use the "Rotate Cube" as I have a touchpad and I cannot use the Keyboard functions if I am correct? I've tried several other similar questions while asking this but they do not seem to work. Ubuntu-12.04.1 LTS Sincerely: Giancarlo Palmiotti

• PASS Summit Preconference and Sessions

  - by Davide Mauri

  I’m very pleased to announce that I’ll be delivering a Pre-Conference at PASS Summit 2012. I’ll speak about Business Intelligence again (as I did in 2010) but this time I’ll focus only on Data Warehouse, since it’s big topic even alone. I’ll discuss not only what is a Data Warehouse, how it can be modeled and built, but also how it’s development can be approached using and Agile approach, bringing the experience I gathered in this field. Building the Agile Data Warehouse with SQL Server 2012 http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=2821 I’m sure you’ll like it, especially if you’re starting to create a BI Solution and you’re wondering what is a Data Warehouse, if it is still useful nowadays that everyone talks about Self-Service BI and In-Memory databases, and what’s the correct path to follow in order to have a successful project up and running. Beside this Preconference, I’ll also deliver a regular session, this time related to database administration, monitoring and tuning: DMVs: Power in Your Hands http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=3204 Here we’ll dive into the most useful DMVs, so that you’ll see how that can help in everyday management in order to discover, understand and optimze you SQL Server installation, from the server itself to the single query. See you there!!!!!

• How to get out of supporting deadend sales pitches?

  - by JoseK

  As part of being a programmer, you often are asked to provide estimates/ make slideware / do technical demos for Sales teams to present to end-clients. Sometimes we go along for the 'technical' discussions or 'strategic capability planning' or some similar mumbo-jumbo. Sometimes, you kind of know which ones are totally going to fail and are not worth pursuing but the Sales guys present fake optimism and extract 'few more slides' out of you or the 'last conference call'. These don't lead to anywhere and are just a waste of time from other tasks for the week. My question is how do you get out of these situations without coming across as non-cooperative. Updated after Kate Gregory's answer: The problem is related to projects we know are doomed (from the technical feedback we've received) But Sales ain't convinced since they've just had a call higher up the management chain - so it's definitely going ahead !

• What are the tradeoffs involved in referencing Context in a library?

  - by C. Ross

  Context is one of the core classes of Android, and many functions it contains are useful in Android library projects, particularly accessing configuration. What are the trade offs involved in accessing the Context in a library, either by injection or by subclassing Application in the library, and subclassing that in the application. Does this make the application brittle or introduce inappropriate coupling?

• How to enable ufw firewall to allow icmp response?

  - by Jeremy Hajek

  I have a series of Ubuntu 10.04 servers and each one has ufw firewall enabled. I have allowed port 22 (for SSH) and 80 (if it's a webserver). My question is that I am trying to enable icmp echo response (ping reply). ICMP functions differently than other protocols--I know it is below the IP level in a technical sense. You can just type sudo ufw allow 22, but you cannot type sudo ufw allow icmp How should attack this problem?

• How to make a PHP function triggered automatically at a user defined time

  - by mithilatw

  I am developing an internal system for a company with PHP using Zend framework. I need one of its functions to execute on a time specified by user. My research on this matter found me several ways of doing this using CPanel Cron jobs and setting up scheduled tasks on the server. But in this scenario, I don't have a CPanel and I already use scheduled tasks. But my challenge is to provide an interface for the user to specify the time to trigger the function.

• HowTo Enable jBullet DebugMode

  - by Kenneth Bray

  I would like to render the physics world of jBullet to debug some issues in my game, and I am not finding too much on enabling the debugDraw method of jBullet. Do I need to write my own debugDraw method, or is there an easier way to draw the physics models to the screen? If there is already a built in method I would prefer to use that, otherwise I guess I will start making my own functions to handle this.

• Taking a Projects Development to the Next Level

  - by user1745022

  I have been looking for some advice for a while on how to handle a project I am working on, but to no avail. I am pretty much on my fourth iteration of improving an "application" I am working on; the first two times were in Excel, the third Time in Access, and now in Visual Studio. The field is manufacturing. The basic idea is I am taking read-only data from a massive Sybase server, filtering it and creating much smaller tables in Access daily (using delete and append Queries) and then doing a bunch of stuff. More specifically, I use a series of queries to either combine data from multiple tables or group data in specific ways (aggregate functions), and then I place this data into a table (so I can sort and manipulate data using DAO.recordset and run multiple custom algorithms). This process is then repeated multiple times throughout the database until a set of relevant tables are created. Many times I will create a field in a query with a value such as 1.1 so that when I append it to a table I can store information in the field from the algorithms. So as the process continues the number of fields for the tables change. The overall application consists of 4 "back-end" databases linked together on a shared drive, with various output (either front-end access applications or Excel). So my question is is this how many data driven applications that solve problems essentially work? Each backend database is updated with fresh data daily and updating each takes around 10 seconds (for three) and 2 minutes(for 1). Project Objectives. I want/am moving to SQL Server soon. Front End will be a Web Application (I know basic web-development and like the administration flexibility) and visual-studio will be IDE with c#/.NET. Should these algorithms be run "inside the database," or using a series of C# functions on each server request. I know you're not supposed to store data in a database unless it is an actual data point, and in Access I have many columns that just hold calculations from algorithms in vba. The truth is, I have seen multiple professional Access applications, and have never seen one that has the complexity or does even close to what mine does (for better or worse). But I know some professional software applications are 1000 times better then mine. So Please Please Please give me a suggestion of some sort. I have been completely on my own and need some guidance on how to approach this project the right way.

• JRE not running correctly on Windows 7 64Bit

  - by dkt91

  An application called DBGL (DosBox Game Launcher) requires JRE in order to run successfully. I had it installed and running on my old Windows 7 32Bit machine without any problems. Today I got my new PC with Windows 64Bit and I cannot get it running anymore. If I install the latest JRE 32Bit version to the \Program Files (x86) folder DBGL says it needs the latest JRE version in order to run and doesn't start. If I install the latest JRE 64Bit version to the \Program Files folder I do not get an error message anymore but the application doesn't start either. Clicking it has literally no effect. Right now I have both JRE versions running parallely and I get the same result I have when only the 64Bit version is installed. Thanks in advance!

• How to use mod_proxy to let my index of Apache go to Tomcat ROOT and be able to browse my other Apache sites

  - by Dagvadorj

  I am trying to use my Tomcat application (deployed at ROOT) to be viewed from Apache port 80. To do this, I used mod_proxy, since mod_jk made me try harder. I used sth like this in httpd.conf: <location http://www.example.com> Order deny,allow Allow from all PassProxy http://localhost:8080/ PassProxyReverse http://localhost:8080/ </location> <Proxy *> Order deny,allow Allow from all </Proxy> And now I can not retrieve my previous sites on Apache, which was running prior to my configuration. How can I have both running?

• Hide GRUB2 menu UNLESS you hold down Shift key: how to make this happen?

  - by Shasteriskt

  I have a Ubuntu - Windows 7 dual-boot set-up, and I would like to have it that my laptop would boot up Windows 7 unless I press down the Shift key right after boot and bring up the Grub2 menu from which I can choose Ubuntu. I researched on Grub2 and options for etc/default/grub and I have tried playing around with combinations with the GRUB_TIMEOUT and GRUB_HIDDEN_TIMEOUT values, but to no avail. I tried setting the GRUB_HIDDEN_TIMEOUT higher than the GRUB_TIMEOUT thinking that both countdown start simultaneously, but no - GRUB_TIMEOUT only starts after the other is done. Is this behavior achievable? If so, how?

• Java.net Reborn

  - by Tori Wieldt

  Java.net, the home of  Java community projects, has been re-launched with a new look and new tools for developers.  The move from CollabNet to the Kenai infrastructure offers more flexibility for developers who want to host or contribute to community projects.  Instead of the large, fixed infrastructure per project (for example, several mailing lists per project), Kenai's ala carte features allow users to take only what they need. "We will continue to have the great mix of blogs, forums, and editorial content as well as new tools on the project side, including Mercurial, Git, and JIRA for developers," Java.net Community Manager Sonya Barry explains. The migration was huge effort. Over 1400 projects were migrated (and some 30 projects are left to go). A large part of the migration was a big cleanup of abandoned projects. With the high abandonment rate of open source projects, the was a lot to remove. The new java.net site is smaller, faster and now the percentage of good, current content is much higher.Check it out at http://home.java.net/

• Nginx proxy SOAP request

  - by user2606078

  looking for a right way to accomplish the following: there is an app that have URL(1) hardcoded and no way/time to change it in the source http://dev.server.com/example.com/admin/soap/action/index?pr=1 and it should use (and get response from) URL(2) http://example.com/admin/soap/action/index?pr=1 what should I configure in Nginx (apache as backup used) conf on dev.server.com in order to give that app when it asks URL(1) answer from URL(2)? On dev.server.com Apache has virtual host: dev.server.com enabled. Also I've tried to proxy in apache instead of nginx by using ProxyPass: <Directory /var/www/dev> Options Indexes FollowSymLinks MultiViews AllowOverride all Order allow,deny allow from all </Directory> <Location /example.com/admin/soap> ProxyPass http://example.com/admin/soap </Location>

• What is proper way to get specific version of package

  - by Peter

  I am using Ubuntu 14.04 LTS I need to use curl package. But it comes in version 7.35.0 with known SSL bug (already fixed in next version) I either need lower version <= 7.33.0 or higher >= 7.36.0 to make it works, but how can I do it? Do I need to manually install curl? I checked synaptics, "Force Version" feature is greyed out. I also checked apt-cache showpkg curl, there is no other version available. I also tried to add "proposed" repositories, no new curl version either. What should I do? I am thinking about getting .deb package from previous ubuntu release...

• Where does UBB store its settings?

  - by pjmorse

  We're moving a UBB forum from one host to another. (This is temporary; we're going to replace the forum eventually, but moving hosts has a higher priority.) We don't have a lot of experience with UBB, so we're feeling our way along in the dark. We got the UBB code installed on the new host, and we've done a dry-run database export from the original site to the new site. However, almost everything set in UBB's Control Panel section didn't come with the database export. If UBB doesn't store this data in the database, where is it stored? And if it is in the database, why would it not show up in a new forum when the database is imported? Did we somehow miss a table?

• How to get experience in large scale databases?

  - by Justin

  I have written applications that are very small scale and the code I write works fine for them. But I have often wondered how the server side code I write would scale up from 100s of queries per day to millions. Also when looking at possible jobs/projects, people are often looking for developers with experience in this sort of high traffic database design so I would at least like to be able to say, I havent gotten to work on a project that was this popular, but I at least have tried to simulate it. Are there tools or frameworks that can generate a lot of traffic or at least simulate what would happen with traffic on different orders of magnitude so I could get some practice writing optimized code for higher traffic applicaitons?

• Answers to Conference Revenue Tweet Questions

  - by D'Arcy Lussier

  Originally posted on: http://geekswithblogs.net/dlussier/archive/2014/05/27/156612.aspxI tweeted this the other day… …and I had some people tweet back questioning/asking about the profit number. So here’s how I came to that figure. Total Revenue Let’s talk total revenue first. This conference has a huge list of companies/organizations paying some amount for sponsorship. Platinum ($1500) x 5 = $7500 Gold ($1000) x 3 = $3000 Silver ($500) x 9 = $4500 Bronze ($250) x 13 = $3250 There’s also a title sponsor level but there’s no mention of how much that is…more than $1500 though, so let’s just say $2500. Total Sponsorship Revenue: $20750.00 For registrations, this conference is claiming over 300 attendees. We’ll just calculate at 300 and the discounted “member rate” – $249. Total Registration Revenue: $74700.00 Booth space is also sold for a vendor area, but let’s just leave that out of the calculation. Total Event Revenue: $95450.00 Now that we know how much money we’re playing with, let’s knock out the costs for the event. Total Costs Hard Costs Audio/Visual Services $2000 Conference Rooms (4 Breakouts + Plenary) $2500 Insurance $700 Printing/Signage $1500 Travel/Hotel Rooms $2000 Keynotes $2000 So let’s talk about these hard costs first. First you may be asking about the Audio Visual. Yes those services can be that high, actually higher. But since there’s an A/V company touted as the official A/V provider, I gotta think there’s some discount for being branded as such. Conference rooms are actually an inflated amount of $500 per. Venues make money on the food they sell at events, not on room rentals. The more food, the cheaper the rooms tend to be offered at. Still, for the sake of argument, let’s set the rooms at $500 each knowing that they could be lower. For travel and hotel rooms…it appears that most of the speakers at this conference are local, meaning there’s no travel or hotel cost. But a few of them I wasn’t too sure…so let’s factor in enough to cover two outside speakers (airfare and hotel). There are two keynotes for this event and depending on the event those may be paid gigs. I’m not sure if they are or not, but considering the closing one is a comedian I’m going to add some funds here for that just in case. Total Hard Costs: $10700 Now that the hard costs are out of the way, let’s talk about the food costs. Food Costs The conference is providing a continental breakfast (YEEEESH!), some level of luncheon, and I have to assume coffee breaks in between. Let’s look at those costs. Continental Breakfast $12 per person Lunch Buffet $18 per person Coffee Breaks (2) $6 per person (or $3 a cup) Snacks (2) $10 per person (or $5 each) Note that the lunch buffet assumes a *good* lunch buffet – two entrees, starch, vegetable, salads, and bread. Not sure if there’ll be snacks during coffee breaks but let’s assume so. Total Food Cost Per Person: $46 Food Cost: $14950 Gratuity: $2691 Total Food Cost: $17641 Total food cost is based on the $46 per person cost x 325. 300 for attendance, 12 for speakers, extra 13 for volunteers/organizers. Gratuity is 18%. Grand Totals So let’s sum things up here. Total Costs Hard Costs: $10700.00 Food Costs: $17641.00 Total:          $28341.00 Taxes:         $3685.00 Grand Total  $32026.00 Total Revenue Sponsorship  $20750 Registration   $74700 Grand Total   $95450.00 Total Profit $63424.00 Now what if the registration numbers were lower and they only got 100 people to show up. In that scenario there’d still be a profit of just under $26000. Closing Comments A couple of things to note: - I haven’t factored in anything for prizes. Not sure if any will be given out - We didn’t add in the booth space revenue - We’re assuming speakers aren’t getting paid, but even if they were at the high end its $12000 ($1000 per session), which is probably an inflated number for local speakers. - Note that all registrations were set to the “member” discounted price. The non-member registration price is higher. There is also an option for those that just want to show up for the opening keynote. There you have it! Let me know if you have any questions. D

• System requirement specification vs functional one - separate docs?

  - by user970696

  A lot of sources (e.g. Wikipedia) mentiones System requirement specification and Functional specification as two separate entities. However, Wiegers in his book writes: The software requirements specification is sometimes called a functional specification, a product specification... This is very confusing for me as I thought FS describes just functions while SRS whole system. From this point of view, FS would contain both non functional and functional requirements and everything else.

• Dealing with engineers that frequently leave their jobs

  - by ??? Shengyuan Lu

  My friend is a project manager for a software company. The most frustrating thing for him is that his engineers frequently leave their jobs. The company works hard to recruit new engineers, transfer projects, and keep a stable quality product. When people leave, it drives my friend crazy. These engineers are quite young and ambitious, and they want higher salaries and better positions. The big boss only thinks about it in financial terms, and his theory is that “three newbies are always better than one veteran” (which, as an experienced engineer, I know is wrong). My friend hates that theory. Any advice for him?

• Code testing practice

  - by Robin Castlin

  So now I have come to the conclusion like many others that having some way of constantly testing your code is good practice since it enables fewer people to be involved (colleges and customers alike) by simply knowing what's wrong before someone else finds out the hard way. I've heard and read some about Unit Testing and understand what it's supposed to do and all. The there are so many different types of bugs. It can be everything from web browser not being able not being able to send correct values, javascript failing, a global function messing up a piece of code somewhere to a change that looked good when testing it out but fails in some special case which was hard to anticipate. My simply finding these errors I learn to rarely repeat them again, but there seems to always be new bugs to be found and learnt from. I would guess maybe the best practice would be to run every page and it's functions a couple of times, witness the result and repeat this in Firefox, Chrome and Internet Explorer (and all smartphones apparently) to make sure it works as intended. However this would take quite some time to do consider I don't work with patches/versions and do little fixes here and there a couple of times per week. What I prefer would be some kind of page I can just load that tests as much things as possible to make sure the site works as intended. Basicly just run a lot of cURL's with POST-values and see if I get expected result. But how would I preferably not increase the IDs of every mysql rows if I delete these testing rows? It feels silly to be on ID 1000 with maybe 50 rows in total. If I could build a new project from scratch I would probably implement some kind of smooth way to return a "TRUE" on testing instead of the actual page. But this solution would for the moment being have to be passed on existing projects. My question What would you recommend to be the best way to test my site to make sure that existing functions does their job upon editing the code? Should I consider to implement a lot of edits first, then test manually the entire code to make sure it still works? Is there any nice way of testing codes without "hurting" the ID columns? Extra thoughs Would it be a good idea to associate all of my files to the different parts of my site which they affect? For instance if I edit home.php I will through documentation test if my homepage's start works as intended since it's the only part of my site it should affect.
