Update, 2009-07-25

In Missouri for a family reunion for the next week or so. We left Friday morning, and got here about 2pm today. We’ll be here until sometime on Wednesday, and then stop at Mammoth Cave on the way back to do some caving.

Anyway, I still have links since RSS never stops :)

  • Ford seems to have had a not-too-shabby quarter, and had one-time gains that helped to post a profit.
  • On top of the news from Ford, The New York Times Comany turned a profit this quarter, reporting second-quarter revenue up from the same quarter last year. I wouldn’t say that the newspaper business is going to be the primary source of news for people again, but it’s nice to see they aren’t going out of business quite yet.
  • In very interesting market news, Microsoft Q4 Sales Miss by $1B; Stock down 7% (about 8% at this writing). This comes on decreased PC sales, but looking forward, may turn around a bit with Windows 7 sales with it’s release sometime later in the year. Microsoft has made a conscious effort in Windows 7 to have it adapt to netbooks in a better fashion, and so to help their sales (hopefully) not slip as much as they recently have.

New Projects

While my time at Sun has shifted a bit from my project, there’re many new things for me to be working on. My agenda has consisted of doing benchmarking on some cool new products, but that should be wrapping up fairly soon. Other than that, I’m working with the 10GE network that we have here internally in McLean. We got the switch (made by Arista) set up first, and we’ll soon be wiring the 10GE network module in one of the 6000 chassis we have here, and then hooking it up to the main internal network for storage nodes, computation, who knows what.

A couple of the other projects I have on my plate include setting up xVM Ops Center, LDAP for the wireless infrastructure, authentication, and other various tools, Virtual Desktop Infrastructure, VPN, and helping to clean up and build out some of our under-utilized space. This list and the other things that need to be done here should keep me busy through the rest of the summer, until heading off for college.

  • The BBC is running an interesting piece called “Unsung Heroes Save Net From Chaos,” about NANOG, the North American Network Operators Group. Even though some of the details aren’t completely factually true and that it’s been toned down so an average citizen could understand sort of what happened in the events referenced in the article, it’s a nice effort and rare event to acknowledge some of the people that, in fact, do keep parts of the internet running.
  • Sun Blogs Tags: ,
  • I found an interesting opinion piece the other day on Why Google's Chrome OS Will Turn to Lead. The author makes an interesting point, but seems to have forgotten that Chrome is based on Linux, which has a worldwide base of developers working on it.

  • California lawmakers seem to have reached a deal to close the budget gap that they were facing. Article linked here: California Reaches Budget Deal, With Billions Cut

  • Meanwhile, the Washington Post wrote about the National Missing and Unidentified Persons System: Database Combines Details of Remains, Disappearences in Hopes of Making Matches. This is a type of technology that has many possibilities of use within and outside of government organizations for data collection and analysis, especially in events like earthquakes or floods.
  • An employee of Opera wrote about a company that made a mistake trying to sell a product to them, leading to a blog post titled: Most Expensive Javascript Ever? It’s a humorous piece that companies should take heed of if they try to single out any particular browser :-) Also linked from here are some cool pictures of one of Opera’s datacenters
  • This one-liner is very useful for copying a partition table from one disk to another; no need to have to do each one manually!
  • This article helps to describe the events surrounding one of the latest passwords to fall due to social networking. The password recovery in this article isn’t specifically linked to Hotmail, as many email providers do something like this to help you reclaim your password.
  • The hotel made famous by the Nixon administration, the Watergate Hotel, has Failed to Attract Bids for it’s sale to a new owner.
  • In two moves that have seemingly shocked the open-source world, Microsoft Makes Second GPLv2 Release In As Many Days. While these contributions help Microsoft’s products mesh better with Linux, and Moodle, there has to be a beginning somewhere, right?

Web Security – The Wac-A-Mole Version

This article from Computerworld earlier today reminded me a lot of the times the TJHSST Student Systems Administrators (of which I’m now a graduate) got to rid our web server of spam that had infiltrated it. The infection I remember most was when a hacked MediaWiki site had been used to upload files to redirect computers to spam sites advertising pills and drugs. It got to the point that there were enough hacked computers hitting our server that most external and internal requests for pages were being refused, and ssh sessions to the server would have a noticeable lag. Eventually one of the other ex-admins got around to doing some scripting, and had a 600-700-line file of computers that were put into ipfilter to eventually block the attack.

Unfortunately we’ve had a couple other smaller infiltrations, but hopefully we closed the hole that they were getting in through. Only time will tell…

My RSS reader gave me lots of reading to do for this weekend, but here are a few of the articles I found interesting/amusing:

Little River Hit With Water Main Break

Little River Turnpike in Northern Virginia turned into a little river today – literally. A water main break was reported, and two eastbound and one westbound lane are now closed in order to work on the problem. First River Road, now Little River Turnpike, what’s next?

Outlook Separation Anxiety Holds Back Google Apps – I’m interested to see how this turns out in the long run. Personally, I really like integration with Outlook or Thunderbird, and the way Google’s IMAP is set up means a few of the folders don’t get mapped correctly. I’m also actually a fan of Outlook Web Access. There are so few integrated solutions on the market that can do the job well. Supporting the system may be an issue, but I’ve heard fewer complaints about Exchange 2007

Sun Ray Silliness

I’ve been meaning to post these for a while so we could submit a service request about it, but the XScreenSaver software in Solaris occasionally messes up the text on the unlock screen, including changing the text’s size and/or font. Here are two examples of the strange behavior:

DSCF7732 DSCF7733

Another behavior that I noticed that I’ve only seen once is green lines appearing on the screen of the Sun Ray. Note that the Sun Ray is currently running Sun Virtual Desktop Infrastructure (VDI) software, which is why it looks like a Windows desktop:

DSCF7843 DSCF7844

Update 2009-07-11, 1628: The two images on the bottom are most likely caused due to interference from the KVM that the ray was using at the time; the model of KVM being used had a history of poor quality.

Sun Ray Soft Client

I downloaded the Sun Ray soft client last night, and I have to say it looks pretty darned neat. The setup I have is sort of unusual, but the program adapts well. I’m running Windows 7 – a supported platform for the soft client – on my laptop, and have it’s VGA output connected up to my Sun Ray 270, which is connected to the Sun Ray servers at TJHSST. I have the soft client running on my laptop’s secondary monitor, and I can just use the “Source” button on the 270 to switch between the two inputs.

From what I can tell, there’s only a slightly noticeable difference between speed on the soft client and the native firmware. I haven’t tried any hard-core video playing like William has, but it seems like it would be more than satisfactory for most of computer users. One thing I’ve noticed when using it on the secondary output is that it doesn’t use the bottom 10-20% of the monitor for the login screen. Once you login it rescales to use the full monitor, but that’s only a minor complaint.

Can’t wait for SRS 5 EA2!

Search Engines Find the Darndest Things

A friend of mine (William) was playing with Google one of the other days, and managed to find a partially-used jewel of mine. It appears that in 10th grade I attempted to start a blog, which I subsequently failed to update after two posts. Check it out here (if you dare). While I use this blog provided by Sun, I'll probaly switch back to the Blogspot one, at least until I find something better or more professional looking. It's possible I'll just abandon it and instead use my website, but we'll decided that when it gets to that point.


Welcome to my blog. My name is Stephen (Trey) Repetski, and I'm working at Sun for the summer. I graduated from TJHSST, and am headed to Rochester Institute of Technology (RIT) in the fall, studying Network Security and Systems Administration (NSSA)
