One of our most frequent feature requests recently has been for the ability to generate an API token that isn’t tied to a particular user. We’re excited to be able to now offer our pro and enterprise customers the ability to create service accounts – a special type of user that has an API token associated with it.

Have you ever had a hard drive which runs out of space while there is still space remaining? Have you ever wondered where that space goes? Let me show you a magic trick First I’ll save a message in message.txt Nothing here nothing there, I’ll save two secret messages the first one is a secret, the second one a big file of text. (but I could save a jpg or an exe).

Originally appeared on Opsgenie Engineering Blog If you are deploying serverless applications in AWS Lambda and using Java, you are well aware of cold start problems. Cold start happens because of the way the Java Virtual Machine works, it kicks in JIT (Just-in-time), and it needs to “warm-up” like a car from the 80s. AWS Lambda caches containers for you, so when idle, it is paused and brought back online immediately as soon as a request a..

A work colleague (let’s call him Owen as that’s his name) asked me the other day “I dont understand the problem space scc et al solve. If you wanted to write a short post, i’d read and share the hell out of it. Basically, it seems like a heap of people can see the need for it, and I’m trying to understand it myself” Owen is one of the more switched on people I know. As such if he is asking whats the point of tools such as scc, tokei..

I have spent a lot of time in front of a computer. That’s because you can do a lot of amazing stuff with it. I don’t think I enjoy the process that much though. Sometimes there is so much clicking and pointing to do simple stuff. I don’t think I would code without using VIM or at least adding VIM bindings to the text editor I’m using. I just can’t use mouse when I code. Coding is discrete. Smallest unit of code is a letter. If you use t..

At first I needed a car rear camera, one thing led to another… My Car, from 2011, only has an LCD display and no rear camera, so I bought a PAL rear camera, we passed some cables from the rear window to the front then everything begun. Here is my journey to transform my car into a modern system running on RPi3 (a never ending project). Hardware I’m using an Rpi3 (old model).

Metrics are data points representing your system behaviour over time. People instrument their long-running apps with metrics to see if there are or were any problems and if the system behaves as expected. There are various metric types, but most common ones are counters, gauges and histograms. Metric types Counter is simply an increasing number. You may use counters to track the number of served requests, number of errors, and so on.

You programmed STM32 microcontroller using Nucleo or Discovery boards. That means you used Serial Wire Debug ( SWD ) for programming/debugging. Now, you are designing a PCB with a STM32 microcontroller on it, which means you have to be able to program it. One solution is uploading the code through a bootloader - a small piece of software, made by ST that has been saved in the protected (read-only) memory of the microcontroller. It’s a..

Whilst casually browsing Hacker News, I stumbled upon a fairly new post which had hit the front page suggesting that a Gitea (a self-hosted GitHub alternative) may have had some of its release binaries compromised . The post linked to an issue on the Gitea’s GitHub page , where at the time it was unclear what & how this had happened, just that the releases had been altered and were distributing something malicious. A few hours later, so..

In the quest to pay debt off as quick as possible, people try to find unique ways (“hacks” if you will) to reduce the timeframe and interest charged. The most popular - and successful - method is the snowball method or one of its variants. Another trick is to split the payments into two or more payments a month.

So here it is… 2019 CERN - Why Open Source Firmware is Important This talk will dive into some of the problems of running servers at scale, including data from surveys about physical infrastructure and firmware concerns. In this talk, we’ll understand how open source firmware will solve some of these common problems. Why is open source firmware important for ....

I was recently involved in a discussion around why would a regular Oracle foreground session wait for the log file sequential read wait event. I then realized that I had never published my Hotsos Symposium 2014 talk about a relatively complex (treacherous?) Oracle performance issue involving multiple problems that “collide”. So I decided to run this presentation as a webinar next week + will demo some of my newer related scripts too!

Over 50% of cyber attacks are executed through malware, whose job is to find a flaw to inject other types of viruses including malware, adware and much more. Knowing the computer remotely, it can spy on the screen and even crypt the files: a wrong click and you lose anything. -Continue to read the article on SerHack.me

I was doing some research for an upcoming exhibition and looked into the question of tone in scientific communication, specifically the stylistic influence of visual representations of knowledge. Obviously the style changed over time, became more abstract, less naturalistic, less.. certain. As if the scientists became troubled by the idea of adding some character to the visual language - which is futile anyway: no matter what you do you e....
