The full RavenDB 4.0 workshop, with over 4 hours of me talking and demoing things live.  I’m covering there everything from how RavenDB stores documents, how to model your data to best take advantage of what RavenDB has to offer all the way to the need for distributed data networks and taking you step by step in setting up a cluster of nodes that replicate data to one another in real time. The main chapters for the workshop are:What is NoSQL and Why do We Need it?The Value in Combining ACID...

We got a serious situation on one of our test cases. We put the system through a lot, pushing it to the breaking point and beyond. And it worked, in fact, it worked beautifully. Up until the point that we started to use too many resources and crashed. While normally that would be expected, it really bugged us, we had provisions in place to protect us against that. Bulkheads were supposed to be blocked, operations rolled back, etc. We were supposed to react properly, reduce costs of operations,...

I got a requirement to make a history form for a workflow. For that, I had to fetch the data from a task list. We can use Rest API, SP Services, or any other methods for this kind of task. So, I chose REST API for the same. Now, the question is, what will be the scenario? Because Workflow status columns of Assign to and Modified Date are not available in the normal list. Then, I learned that we can fetch it from the task list or history list as in workflow all the information resides in Task...

Technical books are interesting. Some of them last for decades, some of them are valid only for a session. I had a few discussions recently about books in a conference, in particular, what books would I recommend. That got me to really think about the topic. There are a lot of books that I think were really valuable for me when I read them that wouldn’t really make sense to recommend / talk about today. Not because they are bad books, but because both the industry and the reader have...

Regardless of how good your software is, there is always a point where we can put more load on the system than it is capable of handling.One such case is when you are firing about a hundred requests a second, per second, regardless of whatever the previous requests have completed and at the same time throttling the I/O so we can’t complete the requests fast enough. What happens then is known as a convoy. Requests start piling up, as more and more work is waiting to be done, we are falling...

We took a memory dump of a production server that was exhibiting high memory usage. Here are the relevant parts:You can already see that there is a lot of fragmentation going on. In this case, there are a few things that we want to pay special attention to. First, there are about 3GB of free space and we are seeing a lot of fragmented blocks. Depending on your actual GC settings, you might be expecting some of it. We typically run with Server mode and RetainVM, which means that the GC will...

About 15 years ago I got a few Operating Systems books and started reading them cover to cover. They were quite interesting to someone who was just starting to learn that there is something under the covers. I remember thinking that this was a pretty complex topics and that the operating system had to do a lot to make everything seem to go.The discussion of memory was especially enlightening, since the details of what was going on behind the scene of the flat memory model we usually take for...

A user reported that when running a set of unit tests against a RavenDB service running on a 1 CPU, 512MB Docker machine instance they were able to reliably reproduce an out of memory exception that would kill the server.They were able to do that by simply running a long series of pretty simple unit tests. In some cases, this crashed the server.It took a while to figure out what the root cause was. RavenDB unit tests are run on isolated databases, with each test having their own db. Running a...

Developers are real passionate about their semi-colons; or lack thereof. Comment threads on GitHub can get a bit…testy…on this topic. What’s a beleaguered1 repository maintainer to do when an issue comment thread gets out of hand? GitHub provides community tools maintainers can use to define community standards for their projects. For example, it’s easy to add a code of conduct to a repository. It’s also possible report offensive comments directly to GitHub. However, a code of conduct is only...

In The Case Against Pay for Performance, I argued against increasing pay based on performance reviews. Checkmate. Case closed. Or so I thought. Like many bloggers, I suffer from delusions of grandeur that millions ponder every word I write, are enlightened by insight, and then compelled to action. Alas, it’s not to be. Instead, I find that belief in the power of rewards to spur higher performance persists despite the ample evidence to the contrary. I suspect that one reason people continue...

There was once a time I regretted not attending a school with a more rigorous engineering program. I would tell myself, I should have gone to an institution like Stanford which has a strong CS program and ties to the bay area tech scene. I’d be further ahead in my career hobnobbing with VCs showering me with champagne and hundred dollar bills. To use the technical term, I was a fool. When I look back at 2017, I’m particularly grateful for the strong liberal arts education I received at...

Not to stereotype tech folks, but, I’ll do it anyways. Most of us could stand to get in better physical shape. I know, that’s about as surprising as a cryptocurrency crash. In particular, I highly recommend a weight training program. If you’re in the Bellevue, WA area, I have just the gym for you, Impact Strength and Performance. But first, let me make the case by sharing my experiences for the past two years. As you can see from the photo, I’ve gotten quite swole (note: costume muscles will...

This year felt a lot like living in the darkest timeline and an episode of Black Mirror at the same time. When I look back at the year, the most significant event for me is also the hardest to write about because it’s deeply personal. Not just for me, but for members of my family. And I often don’t see how the benefit of exposing our private lives overcomes the risks. But in talking to them and others, they encouraged me to share in the hopes it helps others in similar situations. Trigger...

A recent wry tweet by @bcrypt really tickled my funny bone: gitcoin: the author of the commit sha1 with the longest prefix of 0’s in your repository is now the project maintainer The genius in the tweet is how it draws a comparison to Bitcoin’s approach to achieving distributed consensus with achieving consensus on choosing a project maintainer. With Bitcoin, there’s a proof-of-work algorithm that relies on generating SHAs until you find one with a certain number of leading zeros. Git...

In Endless Immensity of the Sea I wrote about a leadership style that encourages intrinsic motivation. Many people I talk to don’t work in such an environment. Even those who work in places that promote the ideals of autonomy and intrinsic motivation often find that over time, things change for the worse. Why does this happen? I believe it’s the result of management entropy. Over time, if an organization doesn’t actively work to fight it, their leaders start to lose touch with what really...

There’s this quote about leadership that resonates with me. If you want to build a ship, don’t drum up people together to collect wood and don’t assign them tasks and work, but rather teach them to long for the endless immensity of the sea. Most attribute it to the French author Antoine de Saint-Exupéry, but it’s doubtful that he wrote these exact words. For one, he’s French, so the words he wrote probably had a lot of àccênts and “le”, “la”, and “et” words in them. This English quote...

I started my first blog at haack.org some time in the year 2000. You can still see pieces of it in the Internet Archive Wayback machine. You have to love this part… Ah, the bad old days of the internet. Back then I could probably count the number of folks who read my blog with the fingers of one hand. Perhaps not even counting the thumb. It was just an outlet for me to share inside jokes with other friends who had their own blogs. I started this before I knew what a weblog or blog was....

Twin Falls lies around a forty minute drive east of Bellevue, Washington. From the trail head, the path leads to views of three separate waterfalls. Yes, three. “Twin Falls” has a nicer ring to it than “Triplet falls.” Focus too much on the hike to the falls and you might miss the side trails down to the Snoqualmie River. The river is cold (or “refreshing” as they say around here) and full of boulders big and small. If you’re careful, you can hop from boulder to boulder to reach an island...
