FeedCity

If your fridge breaks, chances are that you don't have an Arduino, a Dallas temperature sensor, and relays lying around. At least I didn't when mine broke and unfortunately, it was a very hot summer day when it did. So, here's the most simple fix: Use a timer switch. Many pe...

Our fridge broke during the summer of 2015, more or less on the hottest day. It had only been five years old and we had bought it to be eco-friendly but affordable, so it has an A+ rating (in 2010's standards, more on this below). It turns out that a typical cause for this ...

Should a personal blog start with politics? Maybe :-) The last year has been very turbulent regarding international politics. Be it Middle East wars, US elections, or the demise of democracy in Poland - it's been bad news all around, most of which was unexpected, at least to...

It might look like a New Year resolution, that I finally started this blog. However, it's merely a coincidence: over Christmas, I've found time to get some projects done (like fixing the fridge using an Arduino - more on that later), which now makes this blog the next entry on my to do list.

So, Happy New Year, little blog, let's get started :-)

As there seems some confusion and issues with JavaScript dates (here and here) I wanted to have a look at google Chrome and its ES6 capabilities. So I opened the javascript-harmony setting, enabled it and restarted chrome. I opened up the developer tools and hacked some ES6: Running it on Chrome 55.0.2883.87 m: Meh! The web is broken and nobody cares… So far, so good, so what?

I had a JavaScript date issue some time ago. Today I looked at the sources of ChakraCore and dug to the point of interest. // Compute the time value timeValue = TvFromDate(year, month, day, timePortionMilliseconds - utcOffsetMilliseconds); if (isLocalTime) { // Compatibility note: // In ES5, it was unspecified how to handle date strings without the trailing time zone offset "Z|(+|-)HH:mm". // In ES5.1, an absent time zone offset defaulted to "Z", which contradicted ISO8601:2004(E).

JSON View has a security issue due to an XSS vulnerability. JSON Formatter (Chome Store) is an alternative. As I like dark themes I updated the Stylish definition: HTH, Daniel

I have the installed the bash of the Linux sub system on my Windows 10 now for quite some time. Today the prompt informed me about available updates for packages. I tried to sudo to run the apt command but failed. {account} is not in the sudoers file. This incident will be reported. So I had a look at the /etc/sudoers file: ... # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL .

Look at the following code: var x = new Date('2016-01-29T14:00:00'); console.log(x.getTime()); Running it in different browsers is surprising 1454076000000 // Chrome | FF | Opera 1454072400000 // IE | Edge MDN says: The getTime() method returns the numeric value corresponding to the time for the specified date according to universal time. I repeat according to universal time! ECMA Script Spec says: Time is measured in ECMAScript in milliseconds since 01 January, 1970 UTC

The Visual Studio Team is in the process of switching the debugging engine (at least since VS 2013). Today I experienced a really scary behavior. Here is a screenshot of the legacy engine and the new one – both failing to show me that the List contains 75 items, but in different ways. Lesson learned: The only thing you can trust is your trace output!

After an Update of Visual Studio 2015 (14) I wanted to use my usual keyboard short cut ([ALT] + [D]) to expand the “Debug”-menu and … Two menu entries listening to [D] now? For this ridiculous amount of 4 (in words four) menu entries? Seriously? Just delete the folder. And voila: Back. Productive. Done. Dear Microsoft, please stop that kind of marketing making developers every day life harder. I know you can do much better!

Junctions are really useful. It pretty easy to create them inside a command shell on windows: But as it is a command inside cmd.exe and not a executable you cannot use mklink from PowerShell without calling cmd.exe BUT: the *New-Item *cmdlet supports options to achieve the same since Windows Management Framework v.5.

Pretty simple with the search and replace of Visual Studio using Regular Expressions: Find what: throw new ArgumentNullException\(\"([a-z|A-Z]*)\"\); Replace with: throw new ArgumentNullException(nameof($1));

Ok, this is kind of a rant post. I acknowledge that Microsoft is really really doing a good job at certain (developer) spots (ASP.NET, Visual Studio, IIS, SQL Server, …). But NOT at the browser developer tools – I’m listing my issues here, hoping the IE-Team will listen and make the world better for everybody. Dev Tools Pinning Location Why can’t I pin the developer toolbar on the right side as in every other browser.

For security reasons request sizes are limited by default. This is configurable in the web.config file through the httpRuntime sections maxRequestLength attribute. The value is an integer and it’s default value is 4096 (KB) and therefor is 4,153,344 bytes or 4 MB. The configured values can easily be read using the .NET configuration API: If an request is larger than this value a HttpException is thrown when the HttpRequest properties Forms, Files or InputStream are accessed.

I do component based development. Meaning I have 30+ repos, builds and each of them has 1-10 projects – The main library project, tests, samples and so on. The news about the support end for the .NET Framework 4, 4.5 and 4.5.1 was the motivation to update ALL of my projects. I know this is not neccessary because… .NET 4.5.2, 4.6 and 4.6.1 are compatible, in-place updates on top of .

Since more than a decade just community (a non commercial organization that I co-founded) organizes the NRW Conf. This year the attendee numbers increased again slightly which means we cannot grow anymore (because of fire prevention the upper limit is fixed) as long as we stay in the same location (die Börse). But the attendees love it and so do we. I’d like to thank all sponsors, attendees, speakers and stuff for making it such a great event!

Last time I was in Poland was 2006 for the Microsoft Technical Summit. This years October I was invited by the amazing Maciej Pilecki and his company DataMaster who organize the .NET Developer Days Poland. They did an amazing event with an international speaker line up. They got two Scotts (Hanselman and Hunter) and even managed to bring me and my former boss Clemens together (warning the distance between our home places is about 60 Km!

It felt great to be and speak at Basta! again. Thanks to the organization and the audience.
