Azure Service Fabric SDK setup fails with logman beeing unknown cmdlet

Recently I looked into microservies. I’ve read the excelent book “Building Microservices” (affiliate link) and tried to combine Microservices with Microsoft. Luckily for me, I was born in exciting times and Microsoft just released an SDK for their new Microservice Framework Service Fabric.

Unfortunatly I had problem with the installation. Download and installation went well, but on the step Install and start a new cluster I got the error that the cmdlet logman is not known. After some googling I found out that logman is in fact on my laptop. It’s just unknown to my powershell…

Will fix this nasty error. for the win

Whohoo, I gave Atom.Io another try and found a solution  workaround to my @ sign problem:

To fix my problem, I had to unset the keybinding for “autoflow“:

  1. open ~\.atom\keymap.cson
  2. add following line to the file:
  3. restart


Elixir on windows

Lately I got interested in the programming language Elixir. I have not yet done anything besides the very first parts of the tutorial and the fantastic introduction from José Valim.  It looks fun and very capable, even if I have to think around the corner (Elixir is functional and I’m more used to the object oriented programming paradigma)

After reading some parts of the tutorial on my daily commute to work, I was  exited to start. I installed all the needed stuff on my Laptop (so, erlang and elixir).

After that my questions have been “What IDE should I use?” and “What is a good setup?”.  First of all, all the cool kids (this includes the elexir developers) seem to use MacBooks nowadays. This is fine with me, nice peace of hardware. Still, I have a windows Laptop. And I will use this machine until it dies of old age.

So what tools can I use to develop in elixir on windows*?


You need a shell to compile or to test your code. On windows you have two options: The command line (“cmd”) or powershell. Because of reasons I took the powershell. To set the needed variables (where is erlang, elixir and git installed) I used the tipps from here:

Open the file “c:\users\yourUserName\documents\WindowsPowershell\Windows.Powershell_profile.ps1” and add the following lines:


That way, you can type “erl” and the erlang console opens up. The same way you can type in “iex” aaand nothing happens… at least not the elixir REPL shows up. This is because the command iex is used in the powershell for command invocation.

To work around this you can use the command “iex.bat” which brings up the REPL.


“iex.bat” brings up a REPL in powershell. And here my problems start. I realy wanted to love the powershell/elixir combo. First issue: “tab” does not bring up auto completion. This is annoying but no showstopper. But as soon as you progress in the tutorial on the elixir site (on the second page…) you will find this line:

which resulted for me in

Looks, like there is a problem somewhere… probably in the elixir.bat file. A quick check confirms that powershell can work with special characters. And as we can see from the tutorial, elixir does as well.

I found several postings on the internet suggesting to set the codepage correctly (chcp 65001) but this does not work (because this is not a powershell command but a command line command) and should as far as I know not be needed (because powershell uses 16bit unicode internaly. No codepage needed. At least not for most of the western special characters).

Soo powershell is out. The tutorial recommends in this case the use of the command …

… which fails because of the aforementioned reasons (iex being a powershell command). But fear not:

brings up an erlang window with the REPL started. And we even have auto completion!


So comming to the most important (and disappointing) part: I do not ask for much. Auto completion and syntax highlighting. See no complicated task. Also, it would be nice to have some comfort in using the editor.

So which options do I have? Judging by the screenshots and forum posts, the usual editors are Sublime Text, Emacs (especialy with Alchemist) and

Sublime costs $70, which I won’t pay if I don’t see enormous benefits over other tools. After all I’m a student.

Emacs (and with that Alchemist) seems to be working only if you install cygwin or some other *nix environment emulator looks good to me and there can be a lot of packages integrated (packages/settings View/install packages). There is a package for auto completion, one for syntax highlighting even an integration of IEx in Atom … which is  OSX only.

So it is! Proceeding in the tutorial I want to write my first test in the KeyValue example project. And here I felt in the next pit. Under some curcumstances (OS: Windows, Keyboard layout German) you can’t enter an @ sign. It’s just not possible. All other keys seem to work. This actualy is a showstopper.


Elixir looks nice, but up to today I did not find the right tooling under windows. Sure, I can workaround any of these issues (notepad.exe can edit text to) the experience is everything but pleasant .


*If you are asking yourself “What is this man talking about? Any text editor is enough!” then let me tell you that I’m used to .Net development environments which can easily be several gigabytes big and are doing almost everything for you.

YNAB – One year review

Tl;dr: YNAB4 is awesome and you should give it a try. I managed my finances!

How the time flies by! A year ago I installed You Need A Budget 4  as trial on my system. Since then I used the software (or the Android version) everyday. After the trial period I asked the for the free student version of their software. After the license key arrived everything worked fine. No need to import/export data between trial and full product.

So, what can I say after using YNAB4 for around a year?

Accounts – A lot of them

I set up around ten different accounts in YNAB. Despite the fact that it sound as if I am a finance broker or something this seems like the ideal number of accounts for me:

  •  From my pre-YNAB time I have two checkings accounts with which I tried to seperate reoccuring payments and “fun-money”. This was a hassle to manage, because you had to bank-transfer money often.
  • Both checkings accounts came with one free debit card each. So yeah, I use one for Steam purchases and even that seldom. I set up the account in YNAB for the sake of completeness.
  • One of my most often used account is “cash”. For obvious reason (for non-Germans: Credit/debit card use is sparse in Germany. Bank-card or ca$h)
  • Also from my pre-YNAB time: A savings account. It was planned to save money there, but the interest rate of 0.1% is – how to put it… low
  • My student loan has its own account. Currently with a red number, bat soon to be changed :-)
  • I do have a box with lose coins. So I went out to count that and create another account for that ^^ Also I happen to have an box where I put my can deposit into.
  • After I set up my accounts and used YNAB a time I found the need for additional accounts: lent money.

“Lent Money” – How to handle money which isn’t here

I lent a lot (read: often, not high sums) money to friends or my girlfriend, disburse the groceries purchase or, the other way around, someone pays for me because I left my wallet in the office. Because I tended to forget whom to pay what (and who to remind for some Euros) I set up the “lent money” account. When ever I lend money, I make a YNAB transfer to that account. This way I have  the same amount of money in total, but literary spoken in another mans pocket. The same goes for a splited meal with my girlfriend (split categories are great for that). If we pay thirty Euros I set the category to split. The one half goes to my Food category, the other half to the “lent money” account. Kind of special is my girlfriend, who has her own “lent money girlfriend” account. This way we can balance our lent money.

Renconcile often

One thing I learned: Reconcile the account often. Especialy the cash account (because you don’t have a balance/register like with credit cards). Personaly I try to reconcile every week, and even that is sometimes not enough.

Scheduled Transactions

Usefull not only for the rent but for every reoccuring payment with fixed sum. Bonus for using the “Total scheduled outflows this month”-feature in the budget view.

Capture the flag

A feature I have not used once are flags. I honestly have no idea how to put them to good use. Maybe I miss a major feature, but right now I removed the column.

Flags - I do not use them
Flags – I do not use them

Budget View

Regarding the budget view I can just say that I do like it very granular. I have fourteen main categories, each with its according sub categories. I use the note feature a lot, for the budget categories as well as the “budget category per month” column.

From the provided autofill features I use only “Amount budgeted last month” and “Average outflows for last 3 months” regulary. The calculator is unfortunatly only ok: If I use keyboard only it’s clever enough to pop up when I start to type an equotation (“7 * 7”) but does not recognize the multiply sign at the calculator itself. Instead it sums everything up.

Barcelona, day three: parc de la ciutadella and La Barceloneta

Our third day in Barcelona started with Bauernfrühstück. We had some cooked potatoes left and added some eggs, bacon and onions for a delicious meal. After the breakfast we headed for the parc de la ciutadella saw the font de la cascada, an imposant monument with (you would never guess) some cascading wells.

“Gaudi was here”

The park is nice, mostly populated by joggers, school classes and mammoths.
The three buildings which were marked in our map were all unsatisfying. The Castell dels tres dragons (a museum) was closed and had a site fence surrounding the building because of falling debris. Also the hivernacle as well as the umbracle building were closed and a little bit untended.
The university building of the Universitat Pompeu Fabra on the other hand was very nice. I have to admit that I don’t know so many other old university buildings (the campus of my university was build ~ 10 years ago) but the UPF has a nice mix between modern and traditional, old buildings.
Tip (blatantly stolen from our guide): Go into the university main entrance and go into the library. Follow the instructions to the dipòsit de les aigües. It looks really nice.

We had a quiet good (and for Barcelona cheap) meal at the university canteen (noodles with tomato sauce).

After the lunch we went to the beach. Unfortunatly the weather got worse (wind, no sun, wind and around 12° Celsius) and I could not swim in the mediterian sea. I have to catch up on that later. We walked the beach promenade and saw some of the tourist spots (like this copper fish)

The rest of our tour we underwent in the district of Barceloneta, where we tried to find stuff mentioned in our guide. But after ~5 hours of walking we were tired and headed home. We then had a real nice Rioja from 2005 with our salad.

Barcelona, day two: Montjuic and El barri gothic

The second day of our holiday started relaxed: We slept till 11 AM and had a long breakfast with cereals and toast. Interestingly enough the milk you can buy here in the supermarket gets sold uncooled. This seemed a littel bit odd to me, because in Germany almost all milk is getting sold cooled. The only milk in Germany you can buy uncooled is UHT-milk. So I assume the milk is kinda prepared as well. Also interesting: We bought everything for German breakfast (bread, butter, cheese and wurst) but the wurst happened to be cooked ham (called “Mini York”). That alone wouldn’t be bad at all but the ham tasted literally like nothing…

Anyway, we started our sunny day IMG_20150317_135609 with a metro ride (9,95€ for 10 rides, very cheap in comparison to Berlin) to the Placa de Espana where we walked our way up to the Museo nacional d’ Art de Catalunya IMG_20150317_155635. We went to see the German pavilion designed by Mies van der Rohe IMG_20150317_145650.

We planned to use the cable car to district El Raval, which was marked in our map, but this cable car just didn’t exist. So we took the bus to the station universitat where we strolled through the districts. We saw some nice small alleys (and found some guardian gooses IMG_20150317_183347) and ate some “original” catalan food. I bet they took more money from us than it was worth, but that’s the way of the tourist :-)

I do know that the images are all messed up. I have to look into that when I’m back

Barcelona, Day one

Today my fiancée and I flew to Barcelona, for our vacation.  It’s a bit early in the year for a hot Spain holiday, but the city is big enough to cover some bad-weather days.

We flew with germanwings from Berlin at 11 AM and had a pleasantly easy flight. My fiancée and I played Ticket to Ride on her iPad (two times, we had a tie). By the way, Ticket to Ride is a nice game you should absolutly try it once (Amazon Affiliate Link)

In Barcelona we took the Aerobus Barcelona to the plaça del catalunya and walked the last part to our AirBnB accommodation. Next to our apartment is a small café, in which we had  café con leché and a bocadillo, while we waited for out host.

The apartment is small but nice. From our balcony we can see the Sagrada Familia

Picture from our balcony, Sagrada Familia in the distance
If you squint the eyes realy hard and lean from the balcony, you can the it
and we have a Mercato on the opposite of the street. After we ran some errands we prepared a nice tortilla with guacamole. Yummy!
Because of the holidays, I gifted my self with a set of different brands of beer:

Four different beers to taste

So far I tested three of them and they were all very nice.

You Need A Budget – Free students licence

I’m a huge fan of the software You Need A Budget for my budgeting purposes. I was evaluating the software after I realized that my Excel solution is not feasible (read: to complicated).

I installed the 30 days trial version until it expired. After that I uninstalled it and used the Steam demo version. So I had double the evaluation time. And evaluate I did. After that time I was this close to actually purchase YNAB 4 via Steam. But as a student I’m rather short on money. (That’s why I need to budget in the first place…)

But hey, I’ve got more luck than judgement and on the end of march YNAB 4 was released for free for students! Lucky me.


  • You have to be a student of a college (in Germany: Fachhochschule ist auch in Ordnung)
  • This is NOT limited to US students
  • The licence is valid for the current year. After that date you have to ask for a new licence, if you are still a student.

If you are a student and struggle with your money (who doesn’t?) I realy recommend you to try YNAB in the trial version. And if you like it, grab YNAB 4 for free.


I don’t work for YNAB and I’m not related to the company. My only benefit was the free student version.


Home Theatre PC

Following an post from Jeff Atwood about his Home Theatre PC, I decided to look up the current prices of the mentioned components. Or at least the price I would have to pay, if I would like to update my, how to put it… ancient HTPC.

The old lady I call HTPC is a somewhat oldish Acer Aspire Idea 500 (no chance to find a link on the Acer pages, though) with a stunning amount of one gigabyte of Ram and an Intel Core Duo with 1666 Mhz.

This beast of a machine was state of the art when I bought it (that’s a lie) and fitted very well in my setup at the time I bought it. I could hook it up to my TV and my Logitech surround system. Everything was good.

But that all changed when the Fire-Nation attac… when the progression of media and bandwith hit in. Today my HTPC struggles with the evermore demanding tasks like Youtube above 480p or watching a stream via Watchever. Not to mention the impossible task to play a game on this thing (notable exception: Blobby Volley ).

Besides the old age of my HTPC there is a more pressing problem with this pc: It still runs Windows XP Sp3 Media Center Edition. Yes, that is a 13 Year old operating system.  Holy Crap. Five years ago the support went in the extended phase, which means from that point on, there were only security patches distributed. Not something you would expect in the household of an IT-Guy..

Anyway, with all these urgent needs to update my system I looked up the price of the Jeff Atwood HTPC (or at least my interpretation of that). And it’s quite cheap!

For around 400€ I could have a fully functioning multimedia PC with considerably more power (considerably as in: everything better) than my current HTPC. Also, in the price of 400€ is a 120Gb SSD included, which is 20Gb more of storage than the HTPC has now. And It would consume less power and probably be more silent than my current machine.

Because of the small footprint of the case and the mini-ITX board I won’t be able to extend the HTPC as easy as a Desktop PC, but that’s the case now too. But it woud fit nicely in our media rack.

So what components did I choose (based on Jeffs post)?

  • Case (Antec ISK 310-150): Would fit perfect in my media rack. A must buy. ~80€
  • MoBo (ASRock,B85M Pro4): Haswell, USB 3, HDMI… nice Choice. ~60 €
  • Ram (Two 4Gb blocks): Yeah. You need RAM. More is better, but 8Gb is enough. ~75€
  • CPU (Intel Core i3-4130): Here is my first different choice. Jeff choosed the energy saving version of this CPU, cause hsi HTPC is alway on. Mine isn’t, therefore I can save some money now (around 10€) and get more power. Which is always better. ~100€
  • SSD (Some 120Gb thingi): The HTPC has to boot fast. Therefore no HDD. Also I do have a network storage, so no need to attach tons of storage to the HTPC. ~75€

And that’s it. Jeff included the aforementioned tons of storage and another engergy saving power adapter. No need to, so we can save that.

The summed up cost for this pc is around 390€. Affordable, I would say. Let the saving begin!
