Weighted quantile estimators for exponential smoothing and mixture distributions

There are various ways to estimate quantiles of weighted samples. The proper choice of the most appropriate weighted quantile estimator depends not only on the own estimator properties but also on the goal. Let us consider two problems: Estimating quantiles of a weighted mixture distribution. In this problem, we have a weighted mixture distribution given by $F = \sum_{i=1}^m w_i F_i$. We collect samples $\mathbf{x_1}, \mathbf{x_2}, ....

A “more sophisticated” scenario can consist of manually routing all the victim’s traffic to an external server. The attackers can also create fake networks or routers. In other words, it’s possible to act as a proxy under certain conditions without any knowledge from the victims who wouldn’t change their behavior, as nothing would look wrong. This attack allows intercepting cleartext communication. However, simply proxying traffic does ....

Being on-call is often a necessary part of the job, particularly for engineers in a SaaS business. The burden of operations often negatively impacts morale and productivity. If we were to estimate the impact on a team, we could build a model based on incident frequency, ticket severity, time of alert versus sleeping schedules, and other operational metrics. Alternatively, we can ask the on-call engineers directly, which should be more accur....

https://emutos.sourceforge.io/ I have an ST, and an Amiga, but I didn't use either back in the day. But I think this is amazing work and really impressive. So I stuck in on HN and some pillock went "yah boo TOS sucks Amiga is better" like it was 1986. I paraphrase. I am unimpressed. In fact, while I don't want to be mean, you're missing two or possibly three different points... among which are the reasons I posted this link. [....

At work, we’ve been facing lots of issues with Travis CI . The biggest issue is we cannot run more than 5 builds at a time. If some of the builds take a longer time, the rest have to queue. It slows down our velocity to ship things quickly. The other issues we faced are slow initial boot times (Travis uses GCP VMs to run the builds) unable to provision bigger machines for faster builds bugs: some builds missing and randomly failing build..

About 14 years ago I published the OstackProf script that ran on Windows sqlplus clients (the Oracle server could run on any platform that supported ORADEBUG SHORT_STACK). I don’t use Windows almost at all nowadays, so it’s about time to publish the same functionality for MacOSX, Linux, Unix sqlplus clients. This is mostly useful when hacking dev systems, troubleshooting test systems and in rare cases, carefully troubleshooting non-fa..

Setting Emacs up to use your system trash can potentially save your bacon if you mistakenly delete a file, say from dired . Unsurprisingly, the trash safety net also extends to other Emacs areas. For example, discarding files from Magit (via magit-discard) becomes a recoverable operation. As an eshell user, the trash can also help you recover from rm blunders. You can enable macOS system trash in Emacs by setting trash-directory..

When I wrote the " build a distributed PostgreSQL proof of concept " post I first had to figure out how to use Hashicorp's Raft implementation . There weren't any examples I could find in the Hashicorp repo itself. And the only example I could find was Philip O'Toole's hraftd . It's great! However, I have a hard time following multi-file examples in general. So I built my own single-file example . It's not perfect but it helped me ....

The first 3D experience I remember was Sega’s 1991 LaserDisc interactive movie arcade game, Hologram Time Traveler at the Whistler Village arcade in the early 1990s. Our family made annual spring break trips to Whistler back then and the village arcade was something I looked forward to every time. I was too young to be… Continue reading XR, VR, AR 2022 Pt. 1: Dragon’s Lair and Hologram Time Traveler

In my early morning stroll, I sometimes listen to audiobooks. This was the case with The Count of Monte Cristo. Rai Radio 3, the third channel of the national broadcasting service, has been airing Ad Alta Voce (Aloud) for many years. In the program, top-tier actors read old and new literary classics. The quality of these productions is astounding. Audio editions are often edited, which was the case with The Count, as the unabridged editio..

Not too long ago I got into building a metrics dashboard for our resources in Azure. Specifically, we’re running our applications in Azure Kubernetes Services and want to have a dashboard to track how everything is doing. Since we already have our logs emitted to Azure Log Analytics we could use that to build our metrics. Writing the queries to fetch our data from Log Analytics is rather straight forward.

Jacob Kaplan-Moss’s hot take on software quality: Software quality is more the result of a system designed to produce quality, and not so much the result of individual performance . That is: a group of mediocre programmers working with a structure designed to produce quality will produce better software than a group of fantastic programmers working in a system designed with other goals. This leads to the insightful conclusion: I..

The following is a list of curiosities I’ve found while crawling the internet looking for websites. A sort of greatest hits from my search engine. There is no real system or theme to the links, other than the fact that they have made me go “huh, that’s neat” while visiting them. Most of these are effectively impossible to find on Google, since they don’t use HTTPS, and aren’t optimized for mobile, and aren’t plastered in ads and trackin..
