This is Hacker Public Radio Episode 4405 for Friday the 20th of June 2025.
Today's show is entitled, What did I do at work today?
It is hosted by Lee and is about 70 minutes long.
It carries an explicit flag.
The summary is, Lee does some coding and testing for a class library that accesses a database.
You are listening to a show from the Reserve Q. We are airing it now because we had free
slots that were not filled.
This is a community project that needs listeners to contribute shows in order to survive.
Please consider recording a show for Hacker Public Radio.
Hello, I'm Lee.
Today I'll be developing software for my employer.
I'll go through in real time each of the stages in a typical session.
These will include writing the software, writing tests, testing and committing changes to
a remote repository.
The context of this software is that it's a web application which acts as a database
for multiple mechanics within this system.
I'll be looking at creating code that handles aspects of resource allocation.
Okay folks, here we are.
We've just lit up a virtual machine.
It's got Windows 1124H2.
There's this app called Virtual Machine Manager running on KDE.
There's a QMU strobe KVM instance of a machine called Win11 and that's running.
This is all running through the wonders of LibFur.
I would say LibFur is the thing for doing virtual machine stuff on Linux.
You can install it on physical Linux machines to create a virtual machine.
What I reckon is KVM is a hypervisor, QMU quick emulator.
This opens all software for creating emulation and virtual machine environments.
KVM is a type 1 hypervisor, QMU is an emulator, KVM does the CPU virtualization and QMU emulates
other hardware devices.
It's a bit like the GNU Linux, where Linux is the kernel and GNU is everything else.
In this case, KVM is the kernel and QMU is everything else.
So here's Windows 11, I've powered up Visual Studio and here on my right you see it's
two monitors here and by some miracle, the virtual machine is running on both of them because
hey, we've set up two different virtual displays, one for each monitor.
So I'm viewing this thing at not through virtual machine manager, instead I've run
VRT Viewer.
So VRT Viewer is allowing us to see what's going on in this Windows virtual machine and
just for ships and giggles, let's run task manager.
It records it's an AMD Ryzen 3950X 16 core processor, which it is.
It records it's got two sockets and two virtual processors, which is bullshit, but that's
what it thinks it's got and that's what it's got.
So the CPU is supposedly running a 3.5 gigahertz, it's supposedly got 16 gigabytes of memory
and that's the fact this machine has got 64.
This seems to be an SSD on DriveC, capacity is 500 gigabytes, I happen to know that the
real SSD is one terabyte if I recall correctly.
So obviously half of that is allocated to this virtual disk and just so runs as best it
can, this is actually a reward, this skim itch, it's not a QK or anything like that.
And then there's FNAT and I have it to have a zero tier running as well and it records
my IP addresses, some weird friggin thing like 19216812255.
I know this machine is 192168.180, the actual real machine.
On the right screen I have my tests and on the left screen, so this is my class library
on the left.
These are just two solutions in Visual Studio and recently I've added on this class library
a class called staff and a class called role and a class called resource.
I reckon we should have a resource type class, class for types of resource.
I were really going to explaining the domain of this, really what it's all about is to
do with an auto garage, it's a generic set of classes for an auto garage, it's not
so hypothetical, there are hundreds of them using the software apparently or so I've
been told.
So add a new item and this will be a visual basic class because all the cool kids program
still in Visual Basic and not even on net core on net framework, just to explain that
everyone for the last 10 years I guess it's been using net core and some reason I'm using
net framework.
And everyone for the last 10 years I've been using C-sharp longer than 10 years, some
reason I'm using Visual Basic, it will compile down to the same bytecode so half a dozen
of one and so many of another.
Right, that's probably a class called resource type and let's give it some properties,
let's refer to the actual database to see what it is that we're creating in a more abstract
programmatic representation of.
So I'm running up Microsoft SQL Server Management Studio and because it's got Red Gate
Tool Belt it means that the thing takes forever to load as coffee is still hot.
Looking at the databases, looking at the name, the database, looking at the tables and
would you know there is a table called resource type and it has columns, it's got an amazing
number of columns, it's got resource type ID and resource type and score name, so obviously
this is the most complex data structure ever invented, it's got a key and a value.
Now what we're using Mongo for this, let's create a stored procedure though.
We don't want our program to access the database table directly because that would be terrible
for security I guess, it creates an extra layer of abstraction away from the raw data
to have the class library accessing a stored procedure and then a stored procedure accessing
the database table and what I'm going to do is just get another stored procedure and
basically copy what's in there and just change the names, I mean this is 2000 and what
24 at the time we're recording and you know but back in 1995 we had a talk called Case
Computer 8 did software engineering that actually did all of this for you, it's like 2024
and I'm doing all of this by hand converting a data model into a programmatic data access
class, right so because I did staff recently I have got staff ad and staff get so I'm
just going to script the stored procedure as a create my staff ad and I'm going to change
it to a resource type ad and stuff ad and just rename it, stuff underscore ad and renaming
it to resource type underscore ad and as for fields we have a resource type, by the way
we're creating a stored procedure so the SQL is St. Crake procedure, dbo.resource type underscore
all these tables are in the dbo namespace prefix or parameters with an ad sign because
how big is this filled resource name or it can it's an nvarchile 100, it's 100 characters of
is it a varchile would be just ask it but I reckon this is 100 unicode characters that it can
contain right and clean this field resource type name and I'm not giving it an underscore
somehow I've understood that there's convention in the software that our stored procedure
filter we don't give underscores but our table columns we give underscores and anyway we've got
an output parameter new resource type id and that's an integer that outputs so if we've supplied
the resource type id then we just want to update what's there but if we haven't we want it's
creating a one so we're saying if I mean this is all in the procedures main block which is
got begin and end at the beginning and at the end and we're saying if resource type id prefix
with an ad sign is zero so i will not supply one then we want to insert it to dbo dot resource
type and what we're going to insert is one lowly little field which is going to be called resource
type underscore name that's what it is in the table that's the list of fields and then with
the list of values we just give it resource type name prefix with an ad symbol and because we
want to return the resource type id we're saying set new resource type id equals scope underscore
identity that covers the case that we're inserting a new resource type but we might be updating it
so here's our else clause with a beginning in the end if we're updating we say update dbo dot resource
type and set the list of fields that we're updating and actually we're only going to be updating one
field to such a set resource type underscore name equals add symbol resource type not
domain and we've got the where clause the where the where clause and the where clause is where
resource type id equals add symbol resource type id and then we've set what we've set we've
updated what we've updated and now we're setting a parameter called new resource type id is equal to
resource type id prefix by that symbol okay it's now it's now a bit upset because it doesn't
like the word resource type underscore name why doesn't it like that invalid column name
yeah because I've spelled it wrong there's another thing spelled it right is happy with that
and for a caution to the wind and I'll execute this statement and yet come on complete successfully
we just added a stored procedure called resource type underscore add so let's
do another stored procedure called resource type get so I'm just going to script a
staff get and just copy that change was there dbo staff get script stored procedure as a create
there's a comment there maybe I should delete in the comment maybe I should delete it before
put it on comment it's an auto generate comment I'm not sure but I think that the stored procedure
actually saves the comments but I don't know I never bother checking so create procedure dbo dot
resource type and what we're passing in we're passing um nothing actually I'm not passing
anything in we just want to get all resource types because it's a global thing it's not it's not
for a particular user so select resource type id as guess what resource type id and we're also
going to select resource type underscore main as resource type not underscore main
and just delete the rest of the fields because it's not useful
or tell it what table we want so it's ain't from dbo dot resource type and we're going to have
a wear clause no we're not because we're just getting all of them there's no wear clause so let's
execute this and just for the head of things should we have a resource type delete I mean this is
going to play hell with the database because I haven't set any foreign key constraints that there
may be resources with a resource type and then we're just going to go and delete it but hey we can
deal with our higher level of abstraction maybe in the program code I mean you should really deal
with it at all levels kind of going by the idiom of what the other programmer has done so where should
I get a template for delete I think I had a table called roll that I had it and roll is not a
million miles away from resource type I'll but roll didn't have a delete either so resources had
a delete actually let's think about this if roll did not have a delete should should we let
resource have a delete you know what have it sort of resource type have it should we let resource
type have a delete where roll doesn't have a delete basically a roll and a resource that just
a roll is for a member of staff as a resource type is for a resource so I'm I'm making a
executive decision here seen as roll does not have a delete function I'm not giving resource type
a delete function someone can just then we'll go into the database and delete it there's
laziness at work all right so we've created some stored procedures I'll just minimise that rather
than close it now we're back in Visual Studio I've just noticed this is still called class
one dot vb I'd rather it was called resource type dot vb so it's rename
users type dot vb okay um let's give it some private variables private m underscore cases
id as integer well you know what the idiom is that they call it in 32 but Visual Studio
prefers that we call it integer so we're going to call it integer the two are the same
we also have the private so resource ideas wrong it should be called resource type id
and now I'm worrying that I've coded the wrong thing in my stored procedure so let's have a
look at the stored procedure again do you ever have that you only realise you've made a mistake
you think you've made a mistake sometime later with something that's still in your head
you leave the house and you think did I leave the gas or something didn't leave the fridge door
open now I call it resource type id in the add stored procedure and get stored procedure
yeah I call it resource type id there you go it was worrying about absolutely nothing
so it's minimise that private resource type name and string I call it streak let's call it string
and then we'll create a property property in property
these do get first and then set right so get resource type id equals m underscore resource type
id so when we get we're getting that property and we're setting value as in 32 which make m underscore
resource type id equal that value yeah I can see the benefit of having explicit properties
at the same time how often are we ever not going to use the boilerplate why don't we just not
have the private variables and why don't we just use public properties that are self defining
that you just access them directly I mean yeah there's a case that maybe when you're setting one
of these parameters you want it to do some sort of food do or when you're getting it you want to
do something or when you're getting it you want it to calculate some value but for a lot of
what I see to be doing at the moment is boilerplate it's just a complete waste of text in the code
base and but you know by the way when when you find yourself doing stuff that you just think this is
bad coding and then you think well maybe it's good coding but when you think it's bad and you're
doing it just because this is how you've seen it done and you do is it's something called a cargo
you've just seen it done and so you just copy it that's an even a graphic thing and it's not
necessarily politically right to call it that but it's in terms of political greatness of the
original derivation of that word you can look it up but it's just you see you see it being done
that you have you have your get and your set for a property and you think why do I have the get
and the set is probably I just declare the goddamn property anyway so end of rant property resource
type name a string get resource why it's not end of rant it's when you think something you're
doing is wrong it like weighs down on you I'm not I actually feel that this is kind of doing
things the right way so it doesn't it doesn't drag me down too much it's probably a but it's
probably a good way to do things but when you're doing when you're deliberately seem to be applying
bats or for engineer practice and you just do it because that's what you're observing in the code
base already and the things that they teach you when you're studying software engineering
those things aren't on being done as such it this isn't a bit of a newer diverse thing
new divergent thing that it just creates overtighted crews are kind of straining on you
but anyway as I was saying this is not a perfect example of that this is this is where actually
I feel it so it's a reasonable software engineering practice to explicitly define your properties
I mean what does it cost it cost me like five minutes and it costs me ten minutes to worry about
it right start again property resource type name a string get resource type name equals M
underscore resource type name and then set value as string underscore resource type
and why am I not copying and pasting this why am I typing it resource type name equals value
and again something to all my keyboard and my fingers because I've called it a streak rather than string
this this keyboard is one that you really have to push down on the keys is it a mechanical keyboard
I don't know can you judge by the sound I know people go gooey about mechanical keyboards I
don't honestly don't know the difference it's good enough it works but as I say you have to play
definite force and pressure to the keys otherwise it's normally the first key that you press
it may it loses or maybe the last one see when you're doing this your mind has no sense of time
but you can judge the passage of time by how warm your coffee is still that's true okay so let's just
copy the get procedure from staff since I did staff recently so add so in opera stored
procedures is now a class library function a class library function and recently I wrote some
helper functions to make this a lot less verbose so public function add as in 32 dim return value
as in 32 try return value equals stored proc out int as my recent helper function I wrote
and we're passing a connection string in the name of the stored procedure which will be resource type
add underscore add resource type underscore add pass it the object which is just the word me
it's got to be the coolest key word in any program language for in this in Visual Basic and it's
the word me just rather than this in other languages and then data fields an object field so yeah
I forgot to define those I don't add to the top so try to read only data fields as new list of
string equal sorry with curly brackets double quotes resource type the comma double quotes
resource type name without an underscore and then for the private
read it only object fields and because the object fields are the same as the data fields I'll just
set that equal to a reference to the data fields saves typing things twice
back in my add function is unhappy with connection string I've got a feeling
and we should have defined connection string so go back to the staff and oh yeah dim object globals
is new globals dim connection string as string equals object globals dot get connection string
so stick that in our resource type class all right so let's go back to add class library function
return value equals stdproc out int this is just a helper function I wrote myself to save
having to retype tons of stuff over and over pass a connection string pass a dbo resource type
underscore add which in double quotes which is the name of the std procedure with pass it me which
is an instance of the class passing it list of strings data fields and a list of strings object
and we pass it the name of the parameter for what it's going to get out of this std procedure so
we need resource type id and then that's all in a tri block and we catch an exception and we're
sending it to a function called error recorder which is helper function and we just pass that the
parameter name of the class library function which is resource dot add and also we're passing it
the exception method data as it were that x dot message and x dot data to string
and if there was an exception returning and return value of zero just to tell anyone calling
this function or we were not able to add a resource type or update a resource type it was
there as I returned zero right so that's what I add now I'll get I'm going to copy this from
resource dot vb since that seems to be open at the moment so copy in that so and I'm changing it
as a go public function get resource types and it will just pass it in no parameters whatsoever
and it will bring back a list of resource type and then we'll define an object object resource type
of just resource types as new list of resource type and then we're going to have a tri block
and we're calling stored procedure so this is my help function I call it stored
proc in int well actually it's not the right one to use is it because we're not passing it in the
integer so let's go to help functions find out what we should be calling so I'm looking at
module one of vb as where help functions are and would you know a stored proc in int we haven't
done a help function called stored proc so this is the wire work as soon as you know you never
write something in anticipation you always just wait until you actually need it then at that point
write it I think that's as part of the adgeon methodology so I'm going to just copy my function
stored proc in int and just call it stored proc and I'll take out the in parameter
so it's stored proc of t of type t so it's a template team is Stan could stand for any class
and in the case I was talking about it stands for resource type
and the parameters are connection string proc a string it's a name stored procedure the in-param
and the in-vow so they get rid of those so we're not passing it anything in and then we're passing
the data fields and the object fields and we get result so all we have to do is just get rid of
any references that are in-param some adding into a value so just get rid of that
and just checking over then that's okay looks good to me
not going to too much because I'm sure it'll get revealed in my tests if I've made them
a fuck up there so we're not calling stored procedure in int we're calling stored proc
sort of resource type and let's take out our in-parameters because then they're longer there
for this version of the function all right still unhappy what's wrong stored proc is not declared
isn't it I'll call it stored proc fair enough all right stored proc if looks happier
just go to the right name of the variables data fields and object fields and pass it object resource
pipes and actually then call the stored procedure and we've got catch blocking case there's an error
and we'll just let the error handler know that the name of the function that's gone wrong is
resource type dot get resource types I mean you could rewrite this error handler to use what's
called reflection to find out what the name of the function is that's gone wrong but I didn't write
this one so I'll just use the convention that there already is we've got rather than going modifying
someone else's helper function and we just want to return this list that we've set all right so I
think we're done just build a rebuild this class library look for any errors say echo we've got
name of filter property being initialized in an object is later each lies a must start with a dot
you know what I've called I've used the weave rather than from all right I think it's happier now
so that's my data fields I was using the wrong keyword all right that's happy all right now I'm
going to take a toilet break and when I come back I will be writing some tests to test what we've
just written and I know the big boys are supposed to write the test first but no no it's
please just give me the benefit of the doubt I know what I'm doing I'm going to write the test
afterwards okay they're not automated tests to just test to see if the thing even bloody can run
without fraying in an exception you know we're not we're not advanced software engineering here we're
not devops we're pretty book standard basic coding you know as it was several decades ago we haven't
quite caught up with things not automated tests around here right so we're over
and string this coffee focus completely cold it's a hell of a mark from my friend Beno
it's just be happy on it are you going to be more wrong all right so we're going to put the
class library window on the right monitor and the tests on the left monitor because
the left monitor is in front of the keyboard and in front of the chair we're facing the right
monitor is over on one side so I have to move my head to the right one so I should try to spend
my time working on the left monitor and just use the right one as like an adjacent area for whatever
I'm not concentrating on at the moment so we've already got staff tests roll tests and resource
tests so I'm adding a function to call resource type tests
type
in the context of this is a console app you see in a module called tests and sub main is where
they've been run from and just add some resource type tests and some brackets
and then all right two tests now all right resource type and test
and use this type get test
now if that kind of product subs for those it's a modularity
private sub resource type and test
and private sub
sub
and when to private sub and you resource
and it's amazing to give me the end sub that has now thank you so I'm just going to copy
some my other tests because my other tests weren't that bad choose one to get a copy resource get test
just adapt it some inside resource type get test I'm saying console right line
fetching resource types double quotes and in brackets and console right lines again new line
dim object resource types as new resource type yeah so actually we call it dim object resource
type as new resource type dim resource type list as list of resource type equals object resource type
dot get resource types with no practice it's just open closed brackets so now we go
through each one so for each resource type as resource type in resource type list output resource type
in brackets resource type so this point let's create a procedure to output a resource type
so private output resource type and parameter resource type
what isn't like that
and so we didn't call it a sub private sub yeah in C in C you know you don't have to say for sub or
function in all layers of other language you do have to say sub or function so let's say
right console right line in cell dot and in double quotes resource type ID
and space and after the double quotes of ampersand resource type dot resource type ID
and you know what it's going to get cast thoroughly to string and let's say console right line
resource type name ampersand resource type dot guess what resource type name
and let's just have an extra console right line so it leaves a space at the end of it a new line
at the end of it okay so that's our get test now we should do our add test we're to do
with this run or get test and let's do that I'm going to come in out all the other tests
coming out staff test coming out roll test coming out resource tests so just got resource type
tests that's all that's going to run and that's going to run resource type add test resource type
get test but add test hasn't been it's just an empty sub at the moment so any run resource type
get test so let's start that it's building it it's running the xc and we've got an exception
we always do without exception you always get an exception the first time you run a test
so it expects a parameter garage ID idea I've I've missed applied the stored procedure I've given
the parameter that didn't need right so let's go into my software SQL Server Management Studio
that's script resource type get as an auto statement and then the white's complaining about
resource type get because this is an auto statement or create a statement so select resource type
ID as resource type ID resource type I don't see that I've declared a parameter in this stored
procedure so maybe I've declared in this yeah I'm looking in the wrong place I've declared
in the class library have I maybe I'm calling the wrong thing there you go I'm calling resources get
this is what I'm doing wrong I should be calling resource types get so let's go back into editing
the class library so I'm dragging my tests on the left to the right and SQL Server Management
we started for some reason and it's taking forever about to happen so I just minimize that
minimize my console output drag my class library onto the left close down the helper functions
close down staff close down resources tab now in resource tab I'm looking at resource
resources get and this is running stored procedure this is running stored proc so this is my
problem isn't it I've obviously done something wrong in my stored procedure stored procedure
where am I supplying it a parameter I've just realized I'm calling a stored procedure called
resources underscore get so it isn't there's not a problem with my help function the problem is
in the class library the problem is with the get resource types function is calling stored procedure
resources get when it should be calling resource types get so rebuild that see if it will rebuild
of our errors should be a problem and then let's go get my tests and drag them back over to the left
I'll stop that I'll rebuild it so it should pick up the latest version of the class library
and I'll rerun it and what's happened now could not find stored procedure resource types get
okay I probably called it resource type get just confirm that it's got server management studio
go to database is go to name the database go to program ability go to stored procedures
and these stored procedures that I've recently added are called resource type underscore add
and resource type underscore get so they're not plural so I've just called them the wrong
things I need to get my class library back for that I put that it's minimized just unminimize it
and why just change the name of the procedure being called to resource type underscore get
and I did get it right for the add one it's got resource type underscore add so now rebuild the class
library we know what's that and I've got my tests I'll just stop for that executing and start the
test running again okay what's happened right we have something it says oh the name the application
class library tests and it says fetching resource types first resource type ideas one
and resource type name is workshop resource type ID two resource type name is vehicle left
is this type ID three resource type name is air compressor all right it goes all the way up to resource
ID 18 just press any key it closes that down so that work now we want to do my add test so I'm
just going to copy another add test I'll copy my resource add test quite a number of lines of code
so I'm like 20 lines of code so I have to go for it carefully and adapt to look copy and pace going
on so the first line is dimfake as new fake that's just fake is just a class that I created that
produces some test data and then console right by and then in brackets in double quotes adding resource
or make it say adding resource type and that's all there's no parameters so we don't need to tell
it any context which is adding a resource type an extra console right line so we get a new line
dim object resource type as new resource type with resource ID called resource type ID equals
all right so that's telling it that we're just adding a new one we're not modifying one and then
a resource type name we're going to name a resource type name equals fake dot noun search pick a random
noun concrete noun like I don't know an apple this is going to be our resource type and that's it
I mean there's two literally two fields in this class resource type ID resource type name
so now we're saying output resource type so you can see what we're adding and they're giving
that a parameter of object resource type dim a resource type ID as an in thirty two
deciding what color I think to do from now on just say visual studio is happy
we're calling object resource type dot add and then we're console right by
calling added resource type ID and resource object resource type dot ID object resource type dot resource type ID
and we're just producing a new line now modify the thing that was added so modifying resource with
modifying resource type with ID oh you know well we've already said resource type ID is
it's same variable so we do need to be accessing it in the way that we were so it just can
only change support which is right to console right line added resource type ID double quotes and
percent resource type ID you know we're saying modifying resource type ID console right line modifying
resource type ID ampersand resource type ID in an extra line console dot right line and then we're
saying fake it's new fake which will get some new test data we're saying with object resource type
resource type dot resource type ID equals resource type ID and the name as well dot resource
type name equals we'll just give it a fake noun hopefully a bit different fake noun to the
previous one so some modification going on and say hopefully there's a one I think there's a
one in a hundred chance or something like that one in a thousand chance that it'll be the same
but for most of the tests it'll be something different and I'm not checking the results of the
test how many visually checking the results of the tests so it's not going to throw some exception
or error console right line modification in brackets and quotes output resource object resource
type dim new resource type ID as integer equals object resource type and and then let's just
output our ID so console right line modified resource ID modified sorry resource type ID ampersand
new resource type ID and then we'll just output an extra line on the console with console right line
when they get that's that's the tests done so let's just run that see if it actually works we've
got build errors this is having a problem with in the resource type add test with dimension object
resource type as new resource type with dot resource type ID equals zero comma dot resource type name
equals fake oh you know what I've put an extra comma after fake dot noun okay so I've just
got rid of that comma a bit less optimistic and rebuild it before to have running it it did build
a code for errors now so I've run it so it's done the same as before and that's not so it's starting
off with the add test so it's said the name the app class library tests adding resource type
resource type ID zero resource type name tongue it's funny name for a resource type there you go
and it says added resource type ID 19 then it says modifying resource type with ID 19
modification resource type ID 19 resource type name pasta so it's renamed tongue to pasta
so now it's doing the get test in this fetching resource type so hopefully if I scroll down to
the bottom of the list yeah there's resource type ID 19 with resource type name pasta say it's
worked all right that that more or less is it folks um much as I'd like to commit these changes
it's not very much of a change and it is a bit of a rig moral because I have to copy from
drop box into a temporary folder just to change files I have to default compare and then I have to
do get add and then I have to do a get commit and then I have to do a get push to the right branch
so it's a bit of a rig moral no no I'm not going to do that now I'm happy before I've got
it saved in drop box I'm not too worried about losing it I mean what is it in house work all right
close that down yeah that's it I finished my coffee no finish last little sip um check that drop
box is synced those files blocks is actually busy at the moment syncing files so wait shut down
the virtual machine yet then they have me other people keep their code in drop box but for me
I always do because it's got a nice version history you need to go back to a previous
version with a very granular you go back to any version this is what I had back in 1995
with a fax BMS every single version of a file had its own version and then every operating system
since then lost that ability and then you've got yeah I think you've got new this storage
things like butter FS and a ZFS that have regained that functionality but literally folks we had
that functionality in 1995 on a fax BMS terminal and then we lost that functionality but thankfully
I emulate it by having drop box having my files in drop box which just keeps a copy of every
single time you save the file you know why is drop box stalling it's still saying syncing
147 files just let it get on with it goodness knows what it's doing I keep trying to break out of this
I'm here in the wrong case control is it shift F12 yeah can I look down the work that I've done
I'm going to look at a look down a hour I mean pathetic little bit of functionality I've added
but I'm going to look that I've done an hour where do I keep my locks if I work in job line of course
where else I mean I could use a spreadsheet but now I'm using some strange bizarre
recent amazing job line so I've got a folder called log and or a notebook I should say could log
I've got a notebook with the month to a two four twelve and I've got a notebook with
weak ending to a four twelve fourteen such I've already done something earlier today so I've
already got today's date there so just at the end of this note I've had a class and test
for a class and test for resource types and I'll show it down to an hour and I'll synchronise
that and close that down that's everything right I've changed my mind I'm actually going to commit
this stuff to the repository and that's a bit of a chore so I can see the drop box now I'm back
on Linux I'm outside of my virtual machine now see drop box is up to date now just pop back into
the virtual machine check what drop box is dang it still apparently is syncing 36 files
I don't know it's not completely up to date right so drop box hasn't finished syncing on the
virtual machine but it's in sync on the Linux box so let's just assume that the files I've saved
I'll go into a nice little folk parasite program called meld I want a kd plasma desktop
actually on kd plasma five because all hell happened when I went to version six I was running
arch Linux then and I had to give up on arch Linux I tried Fedora and then I had to give up on
that and I ended up on Ubuntu seeing really 80 as it sounds that's where I'm on Ubuntu now
and there's nothing wrong with Ubuntu really do you see why arch people should stick up their
noses at it and after all they're all pretty much the same and I'd say Ubuntu is not without
his problems it's just a different set of problems than you had with arch like Ubuntu seems to be
a bit more stable state wind terms of not so up to date right so the first comparison and I've
got these comparisons saved in the history I'm comparing the class library so I've now got two
pains of left pain in the right pain and I'm scrolling down the list of files to see what's
altered here I can see the module one dot vb has changed so I'm copying that to the right
and I can also see the resource type dot vb wasn't added so I'm copying that to the right that's
all I've done to the class library so now go in the history and go to my tests and after I could
ignore these but there's the bin folder the object folder and the res folder I always have to just
close those because they're just in the way so I just test dot vb that's the only thing that's
changed some copy in that to the right so it's going in my my work my git working copy directory
and then I've just realized I have not updated database schema when you stored procedures
so let's pop back into the virtual machine for run for viewer and I'm using a tool called SQL
compare now compare she's provided by red gate and this is the only bit of software I have mainly
that I can't get any dogmaid for so now I have to go and find my advisor
and I'm not anymore wearing noise canceling your phones I'm also wearing now a blue visor
so I'm moving from my local database which is on 1921168 north of 180 I've got the credentials
and already chosen the name of the database and that is then going to compare it with a script's
folder which is a load of creation scripts and here it's come up with dialog it's comparing the
databases since it's connected to the server what it has done all right it's come up with comparison
and there's seven things they're in both but different 199 objects only on my local server and
1987 identical so don't have to worry about the identical ones the ones that are on both
but different they're actually only different because of a user name being used so I'm ignoring
those so I'm only going to look at the comparison results that are only on my local machine
and almost all of those in a owned by TSQLT or SQLCOP so the ones I'm interested in are owned by DBO
and there's resource type unscalate and resource type unscalate so I've just picked those two
objects and I'm deploying those into the scripts folder some reason this dialog box goes off the
bottom of the screen after moving onto the other monitor before I can then click the next button
and then I say update scripts so that's updated database schema scripts so this is used so we
conversion control our database and then it's decided to recompare things afterwards which just
taking time you said there's a TCP era good knows why that is but anyway it doesn't matter as far
as I know it's done this job so now close down shift of 12 get out for viewer and now I can go back
towards doing an open mail to the file comparison thing I'll go to a comparison of the database scripts
folders they're saying there's no difference obviously that didn't work or Dropbox hasn't copied
across the files yet so then go back into ver viewer click on Dropbox as it copied the files
still thinking eight files whether I look in the actual folder so I'm looking
I've opened up a little finder explorer it's called explorer and windows I've opened up a file
window Dropbox and I'm looking in the name the application in my repose folder in my database
scripts dev folder I'm looking under stored procedures sort by date modified yeah I can see resource
type add and resource type get so they work correctly generated is just Dropbox hasn't uploaded
them yet and I could just see Dropbox has has just this second upload of them so I'll as I did
before close down the virtual machine back to my file comparison program can I rerun this comparison
I'll tell what I just go to history and just click on it again right as it's done the comparison
I already know it's only the stored procedures are different someone can install procedures folder
scrolling down and there's dbo.resource type underscore add.sql and dbo.resource type and
underscore get.sql so copy I'll select both of those and copy if I can and it actually doesn't seem
to light meet selecting both of those so just copy do that one at a time copy to the right
and the other one copy to the right and I can you select multiple yeah you can select multiple
things it's just I was getting confused with the highlighting it didn't seem to want to select both
for once it's public see you're hovering your mouse it makes it different color but yeah you can
shift click and then shift click below and it highlights a range of files some opening console
going into my 10 folder which is working my get repose this is quite a laborious procedure
I'm copying from one place to another in like three stages and also there are three different
repository involved here normally I would only do this once in a while once a week and I did it
earlier today but I'm just doing it again just for demonstration purposes I guess so let's go
to the class library and get status and yeah the module one of vb has been changed and resource
typed of vb has been added because I get and hyphen hyphen all get status again by the way
came up with messages about CRLF about carriage return line feeds will be replaced by line feed
because obviously I've been working on these files in windows and now I'm working on them
in Linux and it has a different way of representing the end of line characters or character
but luckily git the version control software is happy with that and allows for that so now git
commit and as m I think for commit message so what have I actually done I've added class library
or add added class for these types and add function for stored procedure without
and that's committed to git log and I can see that is there I'm going to copy the long
what it looks like an md5 some sort of sequence of hexadecimal which uniquely identifies
the commit log just done and same git push for a chin and I'm pasting my hash and then colon diary
because diary is the name of the branch in return no I never seem to have luck using
the word h capital H E A D which is supposed to represent the top of your git history I always
seem to find I'm doing better to actually explicitly pasting the explicitly pasting the identifier
for the latest commit so now I'll do the same for the other repose I'm going into the test repo
and I'm doing this git status and it shows one modification test stuff it is being modified
so git add my hyphen hyphen all status you can see that's been staged staged the right word
so now git commit minus m and then single quotes added test for intrus type class
let's commit it git log copying the latest commit just like git push push pasting in the commit
and colon name the branch it return let's push that
and then I'm going into the sql scripts repo the development version and git status and so there's
dbo dot resource type and score add dot sql and dbo dot resource type and score get dot sql and they're
both in a stored procedure direct triage so git add hyphen hyphen all status and again I'm ignoring
the crlf message because it deals with that it deals with the line endings git commit minus m you know
it's a lot of audience that's very laborious but sometimes that's helpful to do things in a
laborious way because then it is kind of psychologically helpful sometimes and then there are times when
you make things more efficient and so you get things done quicker in particular just writing
some helper functions so that which I haven't really gone into today but I did end up writing
helper functions to actually make this process a lot smoother it was even more laborious before
before now and as I said I wouldn't normally commit this often the changes I would know it might
be do more changes in one session rather than a fairly limited session just implementing one change
and though I git commit minus m add it stored proceed for two tools types
what a lot more previous commit message was yeah it's about the test so this one was about
stored procedures and git status that's committed so still git log just to see that last commit is
in the history and I've copied the identifier and git push origin paste in the identifier and name
the branch after a colon and that's on its way and something I just did for fun will be to go to
GitHub and actually see the repositories actually reflect change if Firefox all day into launch
which Firefox is deciding not to for some reason I'm running console queue all Firefox
no no process yes point is EF Firefox
grip sorry grip Firefox quite good Firefox no Firefox from me come on it's better yeah sometimes
when Firefox hasn't closed down you just can't run it again I mean yeah it's showing us closed in
kd plasma but it's still running there somewhere and I think I'm using a snap for Firefox
yeah I'm using a snap for Firefox isn't it great Ubuntu you've got like several different ways
of installing software like and I just can't remember which I've used for various software like
OBS obvious standard APT package manager for Firefox I've used a snap and I think I've used flat
pack for something else so yeah we think like well birds and Skype type or speech note discord
use flat pack flat pack is what I prefer but if I can help it I'd use APT over everything else then
flat pack and snap as a last resort there was some reason why the Firefox snap was somewhat
better than the other different methods of installing Firefox in my for my particular use case
not necessarily better for everyone okay so I've got to get up and I'll just go to the scripts
repository and look at the latest commit and it says the name of the branch diary had recent pushes
two minutes ago so I click on the name of that branch and it's got my commit added stored
procedures for resource types and go to the other repositories and GitHub that related to this
organization that is not my not my personal GitHub repositories so although actually the test
one is in my personal is it they're all private repositories not public and the test repo is in
my account whereas the class library itself is in the organization account so I'm looking
at the class library and it says yeah the branch had pushed seven minutes ago and I just
click on that click on the branch and it says added class for resource types and helper function
for stored procedures so I need to go to my repositories to look for the tests the class library
tests and it's yeah only has one branch actually because these tests and you relate to the work
I created specifically for the work I'm doing at the moment it doesn't have a main branch it only
has a diary branch and I can see the latest commit was added test for resource type class
so there you are and none of this is actually added I've not even opened the actual application
I've really just been developing I've really just developed a class for the class library
it has no place in the application at the moment and I've created a number of classes in this way
over the last few days over the last week I say so I've created staff roles resources and resource
types so it's full classes and they're in the tests but none of them are actually in the application
yet and in the application I've like sketched out some approach I'll take to user interface but
beyond that this code is not yet part of the application but it's part of the class library which
is used by the application so that's that's the level that I'm working at the moment not actually
adding directly adding functionality but adding a set of classes because this is a new feature
of the application diary feature or calendar feature and so several classes are being added to
the application although at the same time so I'm finding it better to develop the classes and test
the classes as units and only then when I've got all of them because they're interlinked in terms
of the functionality of the application only then when I start linking it into the user interface
of the application okay that's about all I think definitely there won't be any more now
