Ho appena pubblicato su NuGet l’ultimo aggiornamento di FatturaElettronicaPA , il package .NET per la compilazione e convalida delle fatture elettroniche per la Pubblica Amministrazione. Si tratta della versione 0.2.1 che fa proprie le novità annunciate il 9 Maggio scorso: A partire dal 9 maggio 2016 sono introdotti nuovi controlli sui file trasmessi al Sistema di Interscambio. Per consentire il necessario adeguamento al nuovo regime..

At Jane Street, we have always been heavy users of pre-processors, first with camlp4 and now ppx. Pre-processing makes the infrastructure a bit more complex, but it save us a lot of time by taking care of a lot of tedious boilerplate code and in some case makes the code a bit prettier.

Ever forgotten to add a critical service to monitoring? Want to know if a service or process fails without explicitly monitoring every service on a host? …Then why not use SystemD’s existing knowledge of all the enabled services?

Me: Why is this report different to the one in production? SysAdmin: Dunno. I guess they must have fixed it production and forgot to check it back into source control. If I had a dollar for every time I’ve had that conversation I’d be a rich man. It is usually the result of some late-night troubleshooting and finally the system is working as expected and everyone goes to bed. But the next day, nobody remembers what exactly they changed..

I find it fervently infuriating when someone uses the word passion and degrades it. They degrade the meaning of the word. Passion is the ultimate upgrade of the hobby, a cultivated curiosity. Something you're currently dedicating your life to. You diminish it when blurting that a person that doesn't spend any time outside the "obligatory work hours" on his passion, not even a thought, to be passionate. What is passion if it's not thinking a..

At Cerner, we love Ruby and Rails and use it prominently in our cloud based solutions. When we found out RailsConf 2016 was going to be held in the hometown of Cerner’s headquarters in Kansas City, Missouri, we were excited for the opportunity to support the conference by attending as well as being a sponsor and hosting one of the official after parties. RailsConf 2016 took place in the heart of downtown Kansas City.

This is the story of my involvement with Fine Uploader, how it changed my life, how it affected those around me and my peers at Widen, and how I hope it can continue to have a positive net effect on the open source community and individual developers.

This post for Smashing Magazine looks at one of the most popular image effects, grayscale, to compare its implementation in HTML canvas, SVG, CSS filters, and CSS blend modes.

Today I turn 31. Before the day is through, I'll have ended up celebrating with family and coworkers. And Bash, because as it turns out, Bash can be a bit festive. I find most default Bash prompts to be rather boring. Sure, they vary from platform to platform, but they all seem a little too lite on info that I care about. A few years ago I decided to liven it up a bit.

In high school I did well in math competitions and even qualified for the national team. Part of the reason was that I spend a bunch of time on my own solving math problems. It didn’t feel like a compulsory work. Instead, it was often a compulsive behavior for me. I was often unable to un-glue myself from the math problem at hand. When I saw a good problem, I attempted to solve it. The easier ones I could solve quickly. But some of them....

I’m just going to jump right into the definitions and rigor, so if you haven’t read the previous post motivating the singular value decomposition, go back and do that first. This post will be theorem, proof, algorithm, data. The data set we test on is a thousand-story CNN news data set. All of the data, code, and examples used in this post is in a github repository, as usual. We start with the best-approximating $ k$-dimensional linear subs..

Some of the wifi routers (especially beetel models) provided by airtel broadband is paired with two SSIDs(Access point), One is an actual SSID for internet access and another one called MGMNT, which is used by airtel for maintenance / automatic configuration. The default key for MGMNT is 0987654321, which is hard-coded into the router’s firmware and the stupidest part is there is no option to disable it. Now lets start hacking!, Con....

A recently published vulnerability in the npm `marked` package shows how attackers can use the flexibility of the Markdown format to introduce Cross-Site Scripting vulnerabilities. This post explains the issue and the fix, and discusses the difficulty of sanitizing complex user input.


We previously introduced new playlist representations. The compact representation returns only the playlist itself without any of the tracks…

I was just getting in my terminal when I noticed that the cursor was not blinking. C’moon! I can work with a non-blinking cursor. When a cursor blinks it sets up the pace. I keep moving as the cursor blinks. It is hypnotizing. I can leave my thoughts behind and operate in a state of flow. The blinking cursor is easy to see. I don’t need to look for the white rectangle. I can spot it much easier even when I’m not focused on the screen. I....

Introduction If you are new to Linux or the Mac you might find installing Go to be a bit confusing. It was for me when I started learning Go. Go was the reason I stopped using Windows, which I used for 20 years. Even if you’re experienced with these operation systems, setting up Go might seem a bit of a mystery. With this in mind, let’s walk through installing Go.

We’re hiring here at Flickr and we got pretty excited the other week when we saw Stripe’s post: BYOT (Bring Your Own Team). The sum of the parts is greater than the whole and all that. Genius
Today I gave a talk at RedisConf in San Francisco entitled: Background Tasks in Node.js: A survey with Redis.

Previously on Anvil: version 0.1 was the first one to use incremental rendering approach instead of virtual tree diff’ing. Version 0.2 added support for XML layouts and binding data to existing views. Version 0.3 was about two-way data bindings - most views got simplified lambas for handling user input and many related bugs have been fixed. Today’s version 0.4 takes care of support libraries. I personally rarely use support libraries (at wo..

Looking at a list of unanswered questions people have sent me, I couldn’t find a single reasonable thread that united any of them, save the fact that they all concern my truckly ways. They’re all pretty much orthogonal in the N-dimensional space that truck questions occupy. Let’s get to them. What does your family think of your living situation? I’ve kinda been doing my own thing since I was 15 or 16, and my family sort of accep..

Needed to find the number of days between two dates. Emacs calendar must know this… Fire up the manual (M-x info-emacs-manual or C-h r). Info-goto-node (or g). Type "counting days" and voilá: To determine the number of days in a range, set the mark on one date using `C-', move point to another date, and type `M-=' (`calendar-count-days-region'). The numbers of days shown is [inclusive]{.underline}; that is, it includes the days s..


Quick introduction to a bash-based tool for ops and devs to do JIRA-related read-only tasks that is easy to install, configure and use.

With AWS Lambda, your code is automatically scaled to meet requests. This kind of direct computing is on a trajectory of voracious expansion.
