because it is not inputed into something else, like a variable. also “$($variable.method)” is the way to call methods inside a string. 1 2 3 4 $foundperson= getpeople ` | where {$_.name-eq$name } ` | sort-object born ` | select-object-first 1 powershell is said to be able to use linq. this is technically true but the syntax is so weird that i have never used it. this code though has (almost) the same behaviour and is easy to read. getpeople is a method call. backtick concatenate lines and circumvents that powershell has automatic statement ending with a line end. | pipes object and not strings. where is an alias for where-object . the rest is… linqish. 1 write-host "foundperson:[$foundperson]" write-host an object like $foundperson output the contents of the object. not just the type as in c#. write-verbose “stop:$(get-date-format ‘t’)” this string is outputed only if the method call is made with -verbose . plus an exmple on how to write a method call in a string. 1 return $foundperson finally nothing surprising. except that return can be left out to make the code harder to read. 1 2 3 $people= @{name='ola';born=[datetime]'1970-10-13';children=1}, @{name='anders';born=[datetime]'2011-01-01'} @ tells powershell to create a list of key-value pairs. also often called a hash list. note the comma character. that makes $people an array of key-value pairs. 1 export-modulemember get-persondata only exported mehods are visible outside the module. it is like making them public. tags: powershell | categories: code and development | no comments » powershell for devs, part 1 april 28th, 2018 new to powershell? let me jot down a few good-to-know things. some you already know. some might save you hours of googling. use set-strictmode -version 2.0 . powershell 5.1 is the last windows powershell. from 6 it runs on dotnet core and more platforms. use pester for automatic testing. it runs tests and can mock. note that mocking works differently in powershell than c# as they load code in different ways. don’t patch together your powershell scripts. use the systems thinking you usally do and create a sturdy, thought out, solution with bricks of the right size. just like you would any other solution. for caveats let me explain the file below, row by row. file justasimplescript.ps1 1 2 3 4 5 6 7 8 9 10 11 12 set-strictmode -version 2.0 $temp $temp = 'localvariable' function localfunction( $foo, $bar ){ write-host "local variable is $temp." $foo # the last executed row is returned. } localfunction 'myparameter' enter the above in your favourite text editor. save it as justasimplescript.ps1 . open a console and navigate to the proper folder. execute powershell to get powershell started. then execute .\justasimplescript.ps1′ . the result shows both an exception and some more proper output. 1 set-strictmode -version 2.0 set-strictmode is like `option explicit` in old vb6, it throws an error if you try to evaluate a variable that has not been set, that parenthesises are not used when calling functions and called methods do exist. no code example at stackoverflow shows it and almost no blog article. 1 $temp variables are recognised by the leading dollar sign. as we used set-strictmode above this row throws an exception. but… the program continues to run! 1 $temp = 'localvariable' strings are delimited with apostrophes. quotation works but is over kill, see below. 1 function localfunction( $foo, $bar ){ nothing special about declaring a function like this. declare a function with parenthesises but call it without; it is very easy to get this wrong. also; the parameters are optional by default. 1 write-host "local variable is $temp." write-host is the normal way of outputting text in the console. if it is the correct way is another discussion i won’t dive into without more knowledge. also note the quotation marks. they mean that anything that looks like a variable inside should be evaluated. just like php. just like c# by prefixing a string with $. many online examples use quotation marks for every string. by the time of writing i consider that less good. 1 $foo # the last executed row is returned. to fool newbies, powershell implicitly returns the last executed row with an output. i suggest to make it more readable, prefix with return like so: 1 return $foo # the last executed row is returned. comments starts with a # sign. 1 {...} stuff within curly brackets are a code block. a code block is not only the contents of a method or an if statement but can also be passed around, like a () => {…} lambda in c#. 1 localfunction 'myparameter' this ia a method call. as long as it is powershell leave out the parenthesises. otherwise you have converted your list of parameters to a single parameter call and the single parameters is a list. this rule is not hard to remember but reading code that calls method with lists as parameters is hard to grasp for a newbie. adding insult to injury, calling a c# method from powershell might change the rule. using a file like this, ending in ps1 is typically done by “dot sourcing”. it is quick, dirty and pollutes the global name space. things you would never to in your “regular language”. a call like below makes the contents live only just in the call. 1 .\justasimplescript.ps1 if you want to make the $temp variable and the localfunction live on you start it with yet a period and a space like so: 1 . .\justasimplescript.ps1 but probably you want to make a module instead. which you find in tags: powershell | categories: code and development | no comments » when you are testing, you are not testing code; you are testing intention april 4th, 2018 i just had to get that off my chest. tags: automatic testing , testing | categories: code and development | no comments » how i tested *every* authorisation, authorised or not march 10th, 2018 well… i didn’t, not down to bit level. but i got closer than any time before as every business case was tested. don’t believe my rudimentary text below will simply answer how to do it; it will just give a raw landscape. it took me several nights and 3 iterations before i solved all the tidbits. more important than to test that every role could get to its authorised product was to see that it could not get to unauthorised ditto. so i had to test every combination. testing every permutation of user, role and product was not feasible. each entity has several properties and they are, mostly, not related to authorisation. then we have 2^64 kinds of userid where most of them are not interesting and not even in use. to continue a test on “role of type x or y” is really a “role is hiredinproductscompany”. so i sat down and extracted the if statements from the code. they were like “if loggedon” and “if in role x or y”. every such statement was extracted as a method and moved into a (temporary) helper lib. when i was sure, with visual inspection, i had caught everything, i put some business logic into thought and manipulated and rearranged the methods. they became fewer and matchable to business requirements. gone was “if user.role == administrator and user.company = product.company” but instead “if user.isadministratoratproductscompany(product)”. note that during this process i have not changed any logic and, testing besides, present state could be shipped all the time. now i had to get rid of any technical remains. on the outside it looked ok as the method names where very descriptive in business lingua but inside the authorisation method was “if user.id == 0” or “if challengeduser.id == persisteduser.id”. it was not usable since id as integer is a technical (often a persistance layer construction) solution for recognising an entity. in business terms it is more like “user.ispersisted” and “if challengeduser.sameas(persisteduser)”. i continued redusing the problem space to what i really wanted to test when authorising. this way i seriously minimised the permutations, as an authorisable user did not care about “id” or “name” or “businesspartner” but only “isloggedon” and “role”. with 6 roles that means 12 permutations. with project i came to, say, 32 permutations and user 4. this gives in all 12*32*4=1500 variants. not a problem to test every combination now if i just put some (business) intelligence into creating the tests. #win let’s say 240 of them were positive (autorised) and the rest negative. i started with creating a simple lib for permutating every possible input and them through one test to green light “not authorised”. everything red should be authorised. already here i might have found combinations that was authorised when they should not have been. then i, manually, created a list of every permutation allowing authorisation. well… manually for a programmer is reducing to loops and ifs so one method could create every authorised combination of type a and one of type b. alltogether that is, say, 10 different methods and some manual ones. they were concatenated to a list and i made the test assert authorised and not-authorised according to this list. so now i had a test for every kind of authorisation check testing both authorised and not authorised and tests looks like business logic. tags: authorisation , test | categories: code and development | no comments » recension av lådcykel riese-müller packster 80 february 12th, 2018 [det kommer komma mer information.] denna cykeln. sammanfattning cykeln är löser mina problem och jag använder den varje dag och är nöjd. prislappen är (för) hög (men det tycker jag för en premium-bil också). motorn och transmissionen från bosch är dåligt konstruerad (inte gjord för utomhusbruk eller med last). tl;dr cykelergonomi den är tung . det är inte säkert det gör något. det är inget som känns så länge man cyklar. för mig som normal man är det inget ohanterbart när jag leder eller baxar runt den men jämfört med något som är lätt är den tung. jag vet inte hur tung den är jämfört med andra lådcyklar. jag har tyvärr inte vägt den för att få en rättvisande siffra att jämföra med; en med batteriet på och lådan monterad. den är smidigare än den ser ut. i tighta 90-gradershörn måste man planera lite och kanske ge sig ut i mötande fält. vid tillfälle av 180-graderssväng är det stor risk man måste gå av och leda den fram och tillbaka för att få runt den. att parkera den i cykelställ är som att parkera en bil, man tittar först och svänger sedan och lyckas på första eller andra försöket. det är inget problem att cykla eller leda med två 6-åringar. den vobblar när man cyklar utan att hålla i styret . lösningen är att hålla i styret så det är inte kritiskt men det antyder svaj i ramen. jag har inte jämfört med någon annan lådcykel. jag har cyklat i 50+ km/h, utan barn, vilket känns tryggt , ingen vobbelkänsla alls. det är bra, för jag vill ogärna ramla i den farten med barn i lådan. med 2 6-åringar i lådan höll ja 40+ km/h och var inte det minsta orolig. barnen tjöt av glädje och tyckte det var bättre än liseberg. den ramlar långsamt . vi har ramlat med och utan barn. högre fart i den förra och mer “tappa cykeln” för den senare. barnen satt fastspända och undrade vad de skulle göra medan de väntade på att vi lyfte cykeln igen. det kändes betydligt tryggare än att ha barn på stol på pakethållaren. en egenskap med att ramla med cykeln är att den ramlar långsammare än en vanlig cykel. jag kan inte säga exakt vad det är men jag upplever jag har mer tid på mig att parera och styrningsmekaniken hindrar fullt utslag så man slipper få styret i magen eller fastna mellan ram och styre. jag har också provocerat cyken med halka, sväng, nerförsbacke och fart till en ordentlig ramling (utan barn). utan att kunna jämföra med samma ramling med en vanlig cykel (såå roligt är det inte att ramla) tyckte jag det kändes bra. man sitter inte framåtlutad. eftersom man inte trampar med kraft finns det väldigt lite som håller upp rumpan och ryggen. att sadeln är fjädrad är ingen tillfällighet. detta borde gälla alla elcyklar och mer ju mer bakåtlutad sittpositionen är. en av orsakerna jag valde denna lådcykeln framför annan lådcykel är att denna var mindre bakåtlutad . jag hade dock önskat ännu mer framåtlutning. stödet bra och lite dåligt. först det bra: den är otroligt stabil. jag låter 7-åringarna klättra i och ur den parkerade cykeln och leka i den utan att vara rädd eller ens behöva stå i närheten. den får dock inte stå i nerförsbacke då stödet har precis höjd för att den skall glida sakta framåt och eventuellt (jag har testat lite grann och inte råkat ut för det) fälla upp stödet. uppförsbacke borde fungera bra. eventuellt kan ett tjockt gummiband över bromshandtagen lösa det. trehjuliga lådcyklar har en handbroms, kanske skulle denna ha det också. eller lås bakhjulet. det är också ganska vanligt jag slår i smalbenet när jag ställer cykeln på stödet. framhjulsupphängningen . behövs verkligen fjädring fram? jag kan inte avgöra det. däremot känner jag att hela framhjulsupphängningen, om det är styrlager, navlager, fjädring eller broms kan jag inte avägra, glappar vid bromsning. det är inget problem men i en känslig svängande nerförsbacke är det svårt att känna hur bromsen tar. färg . roligare än svart. tråkigare än orange. mycket fin röd färg på överdraget. motorn walk assist är undermålig. den är för klen , alldeles för klen. en unge i lådan och en liten uppförsbacke blir jobbigt, speciellt som det är jobbigare att leda en lådcykel som är tyngre än en vanlig cykel och man inte vill luta. den orkar precis dra sin egen vikt om det inte lutar mer än någon grad uppför. den är oergonomisk. ett tryck på en liten plastknapp och sedan hålla inne en annan medan man samtidigt håller handen på handtaget är jobbigt. lägg till ett par vantar, eftersom det finns några av oss som inte cyklar bara soliga varma dagar, och man känner inte ens knappen ordentligt. temperaturkänslig motor. specifikationen är några få minusgrader för motorn. en cykel med en motor till det priset monterad borde inte få säljas i sverige utan en varningsskylt. bosch ligger i tyskland. där finns det garanterat minusgrader. jag har cyklat i 5 cm snö och det fungerar bra. hjulen är breda, vilket är både bra och dåligt i snö, men jag antar de breda hjulen behövs p.g.a. vikten. temperaturkänsligt batteri. jag kommer inte ihåg specen för batteriet men ett batteri för flera tusen skall hantera flera minusgrader. det gör det inte enligt specifikation. mycket friktion i motorn och drivningen. att cykla utan batteri är bara att glömma. det är riktigt, riktigt trögt att trampa runt pedalerna utan batterihjälp. för en billig motor hade jag varit ok med det men för en såpass dyr som detta är, är jag inte nöjd. det borde sitta en varningsskylt: denna “cykel” har inget praktiskt bruk utan batteri.

"ipv4address": "172.17.0.3/16", ... }, "f565...3856": { "name": "mongo", ... "ipv4address": " 172.17.0.2/ 16", ... } there we have the ip addresses. out of the box docker containers don’t have a name resolution so we’ll use the ip address to connect. so connect with: mongo 172.17.0.2 and query as before: db.runcommand({find:"projects"}) yay! two connected containers, one running a mongo database and one connected to it and prepared for aspnetcore love. tags: aspnetcore

at the command prompt. the threshold was high. not only was the way of treating my precious source code files new but i also had to learn new commands and how to parse the returned text. then came what is now called github desktop . it made simple tasks even simpler. it couldn’t do any hard tasks but i was perfectly comfortable with this since 99% of my tasks are simple. it is just when i mess up git i need more horse power. so came source tree which made harder tasks easier. not easy since one has to be concentrated; and source tree has a number a bugs and caveats that makes it not as simple to use as github desktop. a client that is very good for what it is good at might suffice. to build a graphical tool for git that is both easy to use for less knowledgable people and complete for an advanced git user is hard, even impossible. alas: the solution to build a simple tool for simple tasks and an advanced tool for advanced tasks is a good idea. tags: git , github desktop , scm ,

have osx as host and win10 as virtual machine. i have also mapped a folder so it is reachable from both osx and windows. osx has docker installed. create the project in windows/visual studio 2017 create a blank solution somewhere both windows and osx can reach. in this article i chose \\mac\home\documents\projekt whatever dotnet version is visible at the top of the dialogue is not of interesting as we are creating a solution file and not much more and then we add dotnet core specific stuff. you can search for the template through “empty” or “blank”. add an aspnet core application project. keep the standard name of simplicity. the path is in the solution \\mac\home\documents\projekt\solution1 dotnet version is still not necessary as it refers to dotnet framework and we are caring about dotnet core. select dotnet core 1.1. this text is written in august 2017 and dotnet core 2 is due november. select webapi. do not add docker support. it would probably not make any change but in this exercise we are targeting running the container in osx. if you change your mind and do want docker-for-windows support you can always do that later with the click of a button. when the project is added compile and run to see that all cog wheels are in place and in working order. tip from the trenches: ctrl-f5 compiles, starts the web server and pop ups a web browser in one click, without having to start the debugger. note the url. it is something like http://localhost:2058 /api/values where /api/values is something to briefly remember. see that in the browser window there is the text [“value1″,”value2”]. it is created through the get method in class controllers/valuescontroller.cs the “normal mvc way”. publish in windows if you right click the project (=activate the context menu in the solution explorer pane on the webapplication1 project) there is a choice “publish…”. afaik it is used for windows or dotnet framework stuff so leave it be. instead we use the cli for restoring, publishing and activating. if you open the console in windows you cannot use the unc path we have put the project in. so instead use pushd like so: > pushd \\mac\home\documents\projekt\solution1\webapplication1 then restore the files with dotnet restore. restoring in this case means pulling in all dependencies so we have everything we need. it will look someting like: > dotnet restore restoring packages for v:\documents\projekt\solution1\webapplication1\webapplication1.csproj… generating msbuild file
