Rgmanager , clustat and clusvcadm are useful tools in cluster land. I recently built a custom resource which I added to one of my service chains. Upon inspecting clustat, I noticed: [root@server1 ~]# clustat Member Status: Quorate Member Name ID Status ------ ---- ---- ------ server1 1 Online, Local, rgmanager server2 2 Online, rgmanager Service Name Owner (Last) State ------- ---- ----- ---..

I’ve been drawing an animal a day. It’s slow going, but I’m glad I started this project because it’s already taught me a lot. For example:

When I was in grade 6, I handed out a couple of 3 1/2" floppy disks to a couple of friends in my class whose parents had recently purchased PCs. On each disk was a game I created. You’d fly a ship horizontally through outer space. It had two controls, up and down, to avoid asteroids. The longer you survived the more points you got. The next day one of my friends said “My dad said you didn’t make that game!”

A tip for lazy Oracle users – type less with ANSI DATE and TIMESTAMP SQL syntax

I am lazy, therefore if I can type less, I will type less. Often people are surprised to see that Oracle supports the ANSI DATE and TIMESTAMP syntax in the SQL code, which allows me to shorten the lengthy TO_DATE( …. , ‘YYYY-MM-DD HH24:MI:SS’) syntax a bit. You can just type this if you want to compare some field to a date (day precision): SQL> SELECT COUNT(*) FROM dba_objects WHERE created > DATE'2012-12-01' ; COUNT(*) 0 SQL>..

Speaking of music created in interesting and unconventional ways, Ryan Challinor used his heart rate to set the tempo for Call Me Maybe by Carly Rae Jepson in this video created for MIT’s Music Hack Day . Permalink.

Found this a little bit ago by chance at the bottom of the Hacker News front page. Very, very cool. “Bass wobble - Notes based on smoothed out NASDAQ overall trading volumes. Wobble rate based on current volatility of the NASDAQ overall trading. Melody - Apple performance vs NASDAQ100 index. Basic beat - Static. Hi-hat - Triggered when the overal nasdaq trading volume is above 2 minute rolling average.” Permalink.

Figure 1: The final product A while back I finally got my 512MB revision 2 model Raspberry Pi to successfully run OpenELEC. The picture to the right shows it running, using a shared network mount to access all of my media files. Some folks requested a write-up detailing how I put everything together, so I'm going to try and provide a generalized walkthrough for those with the initiative to do something like this. Although I'm not ....

A few years ago, when I lived in Minnesota, my friend and I split our time between two activities: building robots and building rockets. We built our robots of Legos and our rockets of cardboard and balsa wood. When we weren’t occupied with one of those endeavors we spent our evenings racing his go-cart around the empty parking lot across from his house, our afternoons building zip lines in his backyard instead of doing the work we were sup..

You get through the less glamorous parts while still being nourished. It’s not a read-your-bible-in-a-year plan. It’s more of a plan for reading the Bible as a way of life. You’re never done. You don’t read the Bible so many times in a year. You read Acts 12 times, all gospels 4 times, etc. You always read different things together. There isn’t as much guilt when skipping a day because you don’t fall behind. 10 chapters a day..

This year has been an amazing year professionally. Together with my employee Martin, and a contractors I’ve been using for visual design and HTML, I’m proud to report we’ve taken the following features for the following customers online 2012. Companies can give their employees mobile phones. Companies pay the bill for these mobile phones. Companies with thousands of such phones get PDF bills which would be inches thick if one ..

As I was working through my seemingly immutable Instapaper queue this morning I came across Jason Snell’s article from earlier this month titled Writing on the iPad ; it was as if I had written the article myself. Over the past six months I made it a point to keep a journal. Not so that I could reflect on my feelings twenty years from now, but so that I could give it to someone very dear to me as a Christmas gift. Rather than keep the ....

I’ve been slowly working on my January game for One Game a Month. So far only two of my ~20 animals are actually drawn and the code ( GitHub ) is very far from finished, but I’m getting there. Also considering joining the Stockholm Global Game Jam, which takes place in January, but have to check some things before committing.

The other day I wrote a short, single paragraph post titled Christmas Break . The gist of the very short article was to say that it’s okay to take a break from working, that your holiday break shouldn’t necessarily be spent catching up on overdue work; taking a break is not a bad thing, and in the grand scheme of things is unlikely to negatively impact your future success. I released the article early in the afternoon of Christmas Eve with..

The tendency to choose the path of least resistance has always been one of the most annoying personality traits I possess. Often manifested as a calm, easygoing attitude it has, however, served me quite well over the years. A double-edged sword if ever there was a more appropriate time to use the phrase, on the one hand the ability to discern and choose the course of action most agreeable to the largest number of dissidents has proven extre....

To close his article Inbox Intentions posted early today, Shawn Blanc made a statement that presently found it’s way to Ben Brooks’s site, where I came across it earlier this evening: “Intentions are dandy, but real men get to work.” After two full days spent celebrating Christmas, this evening found me tired and wanting nothing more than to lay back on my bed and do some light reading. And then I came across Ben Brooks’s quote of the d..

If necessity is the mother of invention, then clients are the source for interesting programming problems, and the need to solve those problems are a never-ending source of discovery for programmers. Such was the case for a recent project in which a lot of data had to be entered quickly and efficiently into an HTML form. The customer was accustomed to using spreadsheets, and wanted, most specifically, for the form to replicate the action ....

Since starting Christmas Break a few days ago I’ve had a lot of time on my hands. I intended to spend a lot of this time catching up on some reading, writing, coding, and working on a new project, but unfortunately as of yet that hasn’t happened. During what relatively little reading I did do over the three days since Christmas Break started though, I’ve noticed that I’m not the only one to step back, take a bit of a break from working, and..

At Offer-Ready , we allow companies to find their optimal mobile phone tariff. We’ve developed a bunch of proprietary algorithms to search over millions of potential combinations of base tariffs and optional packs in under a tenth of a second. We need to store which tariffs are available, and what they cost, in a format that’s easy for us to maintain. However, the calculation process needs it in a format which makes the calculation as qu..

I have again been slacking on updating the blog. I have also been slacking on JavaScript. Since starting work and jumping back into learning C++ I’ve been busy and distracted with other things. I guess if I’m honest with myself part of it is also a lack of motivation or urgency to work on my own projects now that I get to work with/on games at work. It’s like that part of what I want to do now gets fulfilled during the day, so when I get ho..

The First Isomorphism Theorem The meat of our last primer was a proof that quotient groups are well-defined. One important result that helps us compute groups is a very easy consequence of this well-definition. Recall that if $ G,H$ are groups and $ \varphi: G \to H$ is a group homomorphism, then the image of $ \varphi$ is a subgroup of $ H$. Also the kernel of $ \varphi$ is the normal subgroup of $ G$ consisting of the elements which are m..

After about 6 months of work we took the new design for mobilreport online a week or two ago. This software is used by a number of big-name Austrian companies such as Austrian Gaming Industries, Stihl, GlobeAir, Blum, Fohrenburger, Stiegl, neudoerfler, and various others we’re not at liberty to name. I have been working for mobilreport from its beginning. Onestop Concept..

Back in last July – when choosing photos to use in the epic The Dreams of the MeeGo Diaspora post – I noticed that it is quite fascinating to look at the various tablets and mobile phones we’ve been using over the years. Back then they all were so new, shiny, and exciting, and yet hardware moves so fast that something from a year or two ago would look quite dated now. And so I thought it might be interesting to keep some sort of record ....

Double Encoding Issue Building complex websites with Drupal will undoubtedly require you to use the Entity Reference module. Overall, this is a great module with a lot of power and flexibility. It does have one fault, however, and that is that Entity titles are double-encoded when being shown in select boxes, as you can see here. This is nothing more than a small annoyance for experienced users, but show this to a customer and they wil....

In a recent sermon at our church, a pastor student said to us that we are no longer able to say that Jesus will make his disciples fishers of men . Rather, she suggested, we should use the politically correct phrase fishers of people . There is always talk of gender-inclusive language when it comes to Bible translation. But this one seems a little too far. Or it doesn’t feel right. As I have been thinking about this, I came across....
