• Macbook memory upgrade question

  - by James Evans

  I've read some conflicting articles on Macbooks and memory upgrades. Some say you have to buy the "special" Mac memory (bulls$%t), others say manufacturers like Partriot and Ocz will work fine. My Macbook (non-pro) is about 6 mos old with it's 2 GB of memory (SO-DIMM 1066MHz DDR3). Does anyone have any definitive information of what will work? Thanks!

• Hyper-V VM Lab + RRAS + RDP

  - by Dennis Evans

  My background is primarily .NET Development with some System Administration skills. I'm trying to set up a VM Lab for me to test System Applications I'm developing but I've only ever done System Administration in already set up environments; I've never set up my own. My current setup: Server 2008 R2 Hyper-V Host on physical machine (only role enabled) with two NICs. First NIC dedicated for Management w/ DHCP address from company's network. Second NIC dedicated to RRAS VM w/ DHCP address from company's network. RRAS VM has two NICS, one is virtual private internal only NIC w/ static entry. The other is the physical NIC mentioned above. I've joined it to my VMLab.net internal domain. My Active Directory Domain Controller server (ADCT) also runs DNS, DHCP, and Certificate Services which I'm familiar with but don't understand completely. RRAS is already set up with NAT to provide the private internal network with Internet access. What I would like to do is be able to RDP into the servers/computers on the VMLab.net domain from my computer. Do I need to add the Remote Desktop Services role and enable the Remote Desktop Gateway service on RRAS in order to do this or is there a way to set up port forwarding on RRAS to just allow a direct connection to the internal servers...or both? What would the best practices be here? Network Diagram http://i.stack.imgur.com/4qfnk.png

• Can I run a site search like Lucene on a single 2 gig server that's also a web & mysql server

  - by ian.evans

  My site's pages have exceeded the limit of pages for Google Custom Search so many of the results are not found in our site search. I've been reading about Lucene, Nutch, Solr, etc and I'm wondering if I'd have the requirements for running those on a single server that also runs the site (on nginx) and our mysql server. We hae 2 gigs of RAM. I'd appreciate any suggestions for migrating to a new site search.

• Prevent Ultrabay HDD from ejecting on sleep

  - by Bryce Evans

  I have a lenovo T430s thinkpad with a small SSD primary drive and 500gb ultrabay drive. When I put the computer to sleep and then return, I get the message titled "problem ejecting < drive name " "Windows can't stop your 'Generic volume' device because a program is still using it." This pop up is very annoying every time every time I use the computer. I don't want to disable write caching [D:Hardware[drive]policiesquick removal] because I want best performance and never remove the drive. Any ways to avoid this pop up?

• Nginx: Maintenance page and localhost access

  - by ian.evans

  As I prepare to test some changes, I thought I'd set up a maintenance page block so I could do the testing. Just realized though that the maintenance block examples for nginx take the site down for everyone. How do you serve the maintenance page to visitors will still allowing localhost access. Should I just create a new server block listening on another port and deny all, allow 127.0.0.1?

• Dual DVI external monitors from laptop using HDMI

  - by Andy Evans

  I know there may be a few questions similar to this, but my question is regarding specific hardware configuration. I have an Asus U52f laptop with an HDMI out that I currently use to drive my 24" DVI external monitor. My question is I found an HDMI - dual DVI splitter here and was wanting to know is has anyone tried this type of configuration or would the Matrox DualHead2Go be a better solution.

• VMM 2012 Adding Hosts in Trusted Forest

  - by Steve Evans

  I have two forests with a two way trust between them. VMM 2012 sits in ForestA and I can discover hosts in ForestA with no issue. When I try to discover hosts in ForestB I hit one of two issues: If I go through the GUI or use Powershell just like I normally do I get the following error on the job: Error (10407) Virtual Machine Manager could not query Active Directory Domain Services. Recommended Action Verify that the domain name and the credentials, if provided, are correct and then try the operation again. It doesn't matter which account I use. I've tried accounts from both forests, with Admin/Domain Admin permissions all over the place, etc Going through the GUI (can't find the switch in Powershell to duplicate this), I check the box "Skip AD Verification" and it causes the GUI to crash during discovery. I found an article (http://technet.microsoft.com/en-us/library/gg610641.aspx) that describes how to add a host in a disjoint namespace (even though that doesn't apply to me) and it says that VMM creates an SPN if one does not exist. So I verified that the correct SPN's exist in ForestB, that did not help the issue. I have a case open with PSS but they are stuck. I have VMM traces if anyone would like to see them. Any suggestions or ideas?

• Internet Explorer 8 Viewing PDF files vs saving them

  - by Andy Evans

  I have a user asking about viewing PDF files in Internet Explorer. When she clicks the file link on a website, IE prompts her to save the file, which she then has to open to read. What she's not seeing in the prompt is the ability to open the file without having to save it, or, just opening the PDF automatically. She and a few others are having the same problem, while a majority of the user do not have this problem. All of the users have IE 8 and Adobe Reader 9 installed. I've verified that Adobe Reader's "Display PDF in browser" option is enabled. What else should I check?

• Determine if application is re-using SQL Connection

  - by Steve Evans

  I have a legacy app that connects to my SQL 2008 server. I'm trying to determine if the application is re-using it's connection to the SQL server or is creating new connections on a regular basis. Using SQL Profiler I've audited for login events, but that appears to generate an event every time a SQL statement is executed even with apps that I know are maintaining their connection to SQL.

• Save image of running Windows 8 to run from Ubuntu

  - by Noel Evans

  I have a brand new Windows 8 PC. I'd like to hold on to the licensed copy in case I need to run a Windows app at some time in the future but want to wipe the machine completely, installing Ubuntu with no dual-boot. Is it possible to save an image of Windows 8 which can then be run (on the same laptop) from Linux as a virtual machine? If so, what applications (ideally free) should I use to make the image and then run it from Ubuntu?

• Ann Arbor Day of .NET 2010 Recap

  - by PSteele

  Had a great time at the Ann Arbor Day of .NET on Saturday.  Lots of great speakers and topics.  And chance to meet up with friends you usually only communicate with via email/twitter. My Presentation I presented "Getting up to speed with C# 3.5 — Just in time for 4.0!".  There's still a lot of devs that are either stuck in .NET 2.0 or just now moving to .NET 3.5.  This presentation gave highlights of a lot of the key features of 3.5.  I had great questions from the audience.  Afterwards, I talked with a few people who are just now getting in to 3.5 and they told me they had a lot of "A HA!" moments when something I said finally clicked and made sense from a code sample they had seen on the web.  Thanks to all who attended! A few people have asked me for the slides and demo.  The slides were nothing more than a table of contents.  90% of the presentation was spent inside Visual Studio demo'ing new techniques.  However, I have included it in the ZIP file with the sample solution.  You can download it here. Dennis Burton on MongoDB I caught Dennis Burton's presentation on MongoDB.  I was really interested in this one as I've missed the last few times Dennis had given it to local user groups.  It was very informative and I want to spend some time learning more about MongoDB.  I'm still an old-school relational guy, but I'm willing to investigate alternatives. Brian Genisio on Prism Since I'm not a Silverlight/WPF guy (yet), I wasn't sure this would interest me.  But I talked with Brian for a couple of minutes before the presentation and he convinced me to catch it.  And I'm glad he did.  Prism looks like a very nice framework for "composable UI's" in Silverlight and WPF.  I like the whole "dependency injection" feel to it.  Nice job Brian! GiveCamp Planning I spent some time Saturday working on things for the upcoming GiveCamp (which is why I only caught a few sessions).  Ann Arbor's Day of .NET and GiveCamp have both been held at Washtenaw Community College so I took some time (along with fellow GiveCamp planners Mike Eaton and John Hopkins) to check out the new location for Ann Arbor GiveCamp this year! In the past, WCC has let us use the Business Education (BE) building for our GiveCamp's.  But this year, they're moving us over to the Morris Lawrence (ML) building.  Let me tell you – this is a step UP!  In the BE building, we were spread across two floors and spread out into classrooms.  Plus, our opening and closing ceremonies were held in the Liberal Arts (LA) building – a bit of a walk from the BE building. In the ML building, we're together for the whole weekend.  We've got a large open area (which can be sectioned off if needed) for everyone to work in:   Right next to that, we have a large area where we can set up tables and eat.  And it helps that we have a wonderful view while eating (yes, that's a lake out there with a fountain): The ML building also has showers (which we'll have access to!) and it's own auditorium for our opening and closing ceremonies. All in all, this year's GiveCamp will be great! Stay tuned to the Ann Arbor GiveCamp website.  We'll be looking for volunteers (devs, designers, PM's, etc…) soon!

• Talking JavaOne with Rock Star Martijn Verburg

  - by Janice J. Heiss

  JavaOne Rock Stars, conceived in 2005, are the top-rated speakers at each JavaOne Conference. They are awarded by their peers, who, through conference surveys, recognize them for their outstanding sessions and speaking ability. Over the years many of the world’s leading Java developers have been so recognized. Martijn Verburg has, in recent years, established himself as an important mover and shaker in the Java community. His “Diabolical Developer” session at the JavaOne 2011 Conference got people’s attention by identifying some of the worst practices Java developers are prone to engage in. Among other things, he is co-leader and organizer of the thriving London Java User Group (JUG) which has more than 2,500 members, co-represents the London JUG on the Executive Committee of the Java Community Process, and leads the global effort for the Java User Group “Adopt a JSR” and “Adopt OpenJDK” programs. Career highlights include overhauling technology stacks and SDLC practices at Mizuho International, mentoring Oracle on technical community management, and running off shore development teams for AIG. He is currently CTO at jClarity, a start-up focusing on automating optimization for Java/JVM related technologies, and Product Advisor at ZeroTurnaround. He co-authored, with Ben Evans, "The Well-Grounded Java Developer" published by Manning and, as a leading authority on technical team optimization, he is in high demand at major software conferences.Verburg is participating in five sessions, a busy man indeed. Here they are: CON6152 - Modern Software Development Antipatterns (with Ben Evans) UGF10434 - JCP and OpenJDK: Using the JUGs’ “Adopt” Programs in Your Group (with Csaba Toth) BOF4047 - OpenJDK Building and Testing: Case Study—Java User Group OpenJDK Bugathon (with Ben Evans and Cecilia Borg) BOF6283 - 101 Ways to Improve Java: Why Developer Participation Matters (with Bruno Souza and Heather Vancura-Chilson) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Kirk Pepperdine, Ellen Kraffmiller and Henri Tremblay) When I asked Verburg about the biggest mistakes Java developers tend to make, he listed three: A lack of communication -- Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson. No source control -- Developers simply storing code in local filesystems and emailing code in order to integrate Design-driven Design -- The need for some developers to cram every design pattern from the Gang of Four (GoF) book into their source code All of which raises the question: If these practices are so bad, why do developers engage in them? “I've seen a wide gamut of reasons,” said Verburg, who lists them as: * They were never taught at high school/university that their bad habits were harmful.* They weren't mentored in their first professional roles.* They've lost passion for their craft.* They're being deliberately malicious!* They think software development is a technical activity and not a social one.* They think that they'll be able to tidy it up later.A couple of key confusions and misconceptions beset Java developers, according to Verburg. “With Java and the JVM in particular I've seen a couple of trends,” he remarked. “One is that developers think that the JVM is a magic box that will clean up their memory, make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try and force Java (the language) to do something it's not very good at, such as rapid web development. So you get a proliferation of overly complex frameworks, libraries and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!”I asked him about the keys to running a good Java User Group. “You need to have a ‘Why,’” he observed. “Many user groups know what they do (typically, events) and how they do it (the logistics), but what really drives users to join your group and to stay is to give them a purpose. For example, within the LJC we constantly talk about the ‘Why,’ which in our case is several whys:* Re-ignite the passion that developers have for their craft* Raise the bar of Java developers in London* We want developers to have a voice in deciding the future of Java* We want to inspire the next generation of tech leaders* To bring the disparate tech groups in London together* So we could learn from each other* We believe that the Java ecosystem forms a cornerstone of our society today -- we want to protect that for the futureLooking ahead to Java 8 Verburg expressed excitement about Lambdas. “I cannot wait for Lambdas,” he enthused. “Brian Goetz and his group are doing a great job, especially given some of the backwards compatibility that they have to maintain. It's going to remove a lot of boiler plate and yet maintain readability, plus enable massive scaling.”Check out Martijn Verburg at JavaOne if you get a chance, and, stay tuned for a longer interview yours truly did with Martijn to be publish on otn/java some time after JavaOne.

• Session Report - Modern Software Development Anti-Patterns

  - by Janice J. Heiss

  In this standing-room-only session, building upon his 2011 JavaOne Rock Star “Diabolical Developer” session, Martijn Verburg, this time along with Ben Evans, identified and explored common “anti-patterns” – ways of doing things that keep developers from doing their best work. They emphasized the importance of social interaction and team communication, along with identifying certain psychological pitfalls that lead developers astray. Their emphasis was less on technical coding errors and more how to function well and to keep one’s focus on what really matters. They are the authors of the highly regarded The Well-Grounded Java Developer and are both movers and shakers in the London JUG community and on the Java Community Process. The large room was packed as they gave a fast-moving, witty presentation with lots of laughs and personal anecdotes. Below are a few of the anti-patterns they discussed.Anti-Pattern One: Conference-Driven DeliveryThe theme here is the belief that “Real pros hack code and write their slides minutes before their talks.” Their response to this anti-pattern is an expression popular in the military – PPPPPP, which stands for, “Proper preparation prevents piss-poor performance.”“Communication is very important – probably more important than the code you write,” claimed Verburg. “The more you speak in front of large groups of people the easier it gets, but it’s always important to do dry runs, to present to smaller groups. And important to be members of user groups where you can give presentations. It’s a great place to practice speaking skills; to gain new skills; get new contacts, to network.”They encouraged attendees to record themselves and listen to themselves giving a presentation. They advised them to start with a spouse or friends if need be. Learning to communicate to a group, they argued, is essential to being a successful developer. The emphasis here is that software development is a team activity and good, clear, accessible communication is essential to the functioning of software teams. Anti-Pattern Two: Mortgage-Driven Development The main theme here was that, in a period of worldwide recession and economic stagnation, people are concerned about keeping their jobs. So there is a tendency for developers to treat knowledge as power and not share what they know about their systems with their colleagues, so when it comes time to fix a problem in production, they will be the only one who knows how to fix it – and will have made themselves an indispensable cog in a machine so you cannot be fired. So developers avoid documentation at all costs, or if documentation is required, put it on a USB chip and lock it in a lock box. As in the first anti-pattern, the idea here is that communicating well with your colleagues is essential and documentation is a key part of this. Social interactions are essential. Both Verburg and Evans insisted that increasingly, year by year, successful software development is more about communication than the technical aspects of the craft. Developers who understand this are the ones who will have the most success. Anti-Pattern Three: Distracted by Shiny – Always Use the Latest Technology to Stay AheadThe temptation here is to pick out some obscure framework, try a bit of Scala, HTML5, and Clojure, and always use the latest technology and upgrade to the latest point release of everything. Don’t worry if something works poorly because you are ahead of the curve. Verburg and Evans insisted that there need to be sound reasons for everything a developer does. Developers should not bring in something simply because for some reason they just feel like it or because it’s new. They recommended a site run by a developer named Matt Raible with excellent comparison spread sheets regarding Web frameworks and other apps. They praised it as a useful tool to help developers in their decision-making processes. They pointed out that good developers sometimes make bad choices out of boredom, to add shiny things to their CV, out of frustration with existing processes, or just from a lack of understanding. They pointed out that some code may stay in a business system for 15 or 20 years, but not all code is created equal and some may change after 3 or 6 months. Developers need to know where the code they are contributing fits in. What is its likely lifespan? Anti-Pattern Four: Design-Driven Design The anti-pattern: If you want to impress your colleagues and bosses, use design patents left, right, and center – MVC, Session Facades, SOA, etc. Or the UML modeling suite from IBM, back in the day… Generate super fast code. And the more jargon you can talk when in the vicinity of the manager the better.Verburg shared a true story about a time when he was interviewing a guy for a job and asked him what his previous work was. The interviewee said that he essentially took patterns and uses an approved book of Enterprise Architecture Patterns and applied them. Verburg was dumbstruck that someone could have a job in which they took patterns from a book and applied them. He pointed out that the idea that design is a separate activity is simply wrong. He repeated a saying that he uses, “You should pay your junior developers for the lines of code they write and the things they add; you should pay your senior developers for what they take away.”He explained that by encouraging people to take things away, the code base gets simpler and reflects the actual business use cases developers are trying to solve, as opposed to the framework that is being imposed. He told another true story about a project to decommission a very long system. 98% of the code was decommissioned and people got a nice bonus. But the 2% remained on the mainframe so the 98% reduction in code resulted in zero reduction in costs, because the entire mainframe was needed to run the 2% that was left. There is an incentive to get rid of source code and subsystems when they are no longer needed. The session continued with several more anti-patterns that were equally insightful.

• Windows installer constantly asking for Word CD

  - by Dennis

  My daughter uses Word and at some point in the past tried to install a feature which needed the install CD. She no longer has the CD, figured she could live without the feature and cancelled the install. However, every time she boots the computer it tries to resume the install and asks for the CD. All you have to do is hit cancel but it seems a bit annoying to me to have to do that each time you boot. How can I get it to permanently abort the install?

• How to get HP ASM to work under Xen Hypervisor?

  - by Dennis

  I have a HP DL560, currently running Debian Squeeze as dom0 on Xen Hypervisor, and the fans constantly run at 100%. In the past this wasn't a problem because I could install HP's ASM which includes fan management. However since I have installed a xen enabled kernel, the hp-health driver (the piece of ASM that controls the fans) won't start (at boot or manually). Anyone know of any way to make it work? (Or any other method of controlling the fans safely.) Note that the server has four i386 Xeon CPUs, each with its own fan, plus an extra case fan, and all of the fans can be doubled for redundancy. Also everything works fine under Squeeze without the xen-enabled kernel (can still boot the other one and hp-health loads fine on boot).

• Can't figure out how to make Slitaz USB persistent

  - by Dennis Hodapp

  I installed Slitaz on my USB. However I can't figure out how to make it persistent automatically. There are different sources telling me different ways to make it persistent. One told me to add "slitaz home=usb" to the syslinux.cfg file like this: append initrd=/boot/rootfs.gz rw root=/dev/null vga=normal autologin slitaz home=usb but it didn't work for me. http://www.slitaz.org/en/doc/handbook/liveusb.html gave an example of how to do it manually but I didn't try it and I also want it to happen automatically. custompc.co.uk/features/602451/make-any-pc-your-own-with-linux-on-a-usb-key.html is an older article that also explains how to make the USB persistent but I don't want to try it cause it looks outdated (from 2008) does anyone know the best way to make the USB automatically persistent?
