One job I picked up was for an IoT Start Up. It was quite interesting work, reporting to the technical director, who was an electronics engineer, who was designing the hardware himself, they had a couple of firmware guys already, and just needed someone to take care of the software.
So they said they needed something in Azure that they could stream their data to and provide analytics for their clients. It had to be Azure, and it had to be Azure Native, and was to be Multi-client, as they had a deal with Microsoft to showcase how well Azure works in the IoT space at an exhibition/conference in 3 months time.
So I worked flat out for 3 months, on a whole variety of technology, from C++ to get the radio packets from their IoT chip, Python to run on the hub to take the data from the C++ and stream it to the cloud, Azure IoT Hubs in every continent to receive the data and store it an a Cosmos DB, and then Power BI analytics wrapped up in an Angular front end that the clients could log into.
Got it finished 2 days before the show, and they were so pleased I got flown business class to Singapore to be on the stand and talk to customers.
The first sign of trouble was when we arrived at the show to find we just had one of those little circular tables with two stools in the middle of the floor, about two feet across and no power.
No problem, I was able to sort that, swapping laptops in and out.
Microsoft were really happy with what we had, and couldn't believe I had thrown it all together in 3 months.
We picked up a potential customer for the system, a major Asian Telecoms company.
Then when we got home, the CEO swooped in. I had never met this guy before. Imagine one of the VC guys from Silicon Valley, or the CEO from the IT Crowd. You get the picture. Could talk the hind leg of a donkey, and real street smart, but no brains. He insisted on "taking it from here" and flew alone to strike the deal with the customer. Came back with an MOU in his pocket and said to me, their guys will be in touch with you.
Then I got a call. Can you send us the source code and tell us how what servers we have to run this on?
Um, its cloud native.
No, we can't use a cloud it has to be on our servers - your CEO told us that was no problem..
He hadn't even taken the trouble to find out what it was we had built, and what he was selling.1 -
Dear Microsoft power bi team.
Go fuck yourself. Put that dashboard up your ass. The documentation for this is a joke.
The doc says I can get my tokens from azure portal. But guess what. The portal is a sea. And seems like powerbi is moved out from portal to its own powerbi.fuckyoumicrosoft.com
What the actual fuck you dimwits. Why don't you document it properly ?
For fuck sake. Go show up your analytics deep into your pie chart.2 -
I think I just miiiight have found a new job, but before, some comments about the state of the data engineering industry:
- Sooooooo many people outsource it. Man, outsourcing your data teams is like seeing the world through an Apple Vision Pro fused to your skull. Fine if it is working well, but you will go blind of your subscription expires. Or if Apple decides to ban you. Or if they decide to abandon the product... you are entirely dependent on their whims. In retrospect this is par for the course, I guess.
- Lots of companies think data engineering *starts* with an SQL database. Oh, honey, I have some bad news.
- Quite a few expect MS POWER BI will be able to deliver REAL TIME DASHBOARDS summarizing TERABYTES of data sourced from SQL SERVER (or similar). Facepalm.
- Nearly all think the handling of data engineering products is just like that of software engineering. Just try. I dare you.
- Why people think that "familiarity in several SQL dialects" is something to brag about?
- Shit, startups. Startups are dead, boomers. Deader than video rental physical stores.
That's all. On to the next round of interviews! -
i was about to talk about golang - but it can wait.
snapchat's discover section is TERRIBLE. the amount of BULLSHIT, INCORRECT INFORMATION, AND PURE IDIOCY IS MAKING IT TERRIBLE.
now, usually, i rant about mashable when i say it's terrible. AT LEAST WHEN MASHABLE WROTE ABOUT THIS THEY WERE CORRECT. but no, alas, my faith in humanity is put to an all time end. a new evil has arose, by the name of "wired."
of course, and incredibly late to the party, a "tech" outlet wrote about bitcoin. the headline was "is bitcoin killing the planet?" IT HAS BEEN POSSIBLY THE STUPIDEST ARTICLE IVE READ OF ALL TIME. THEY CLEARLY HAVE NO IDEA ABOUT ANY SHIT THEYRE TALKING ABOUT.
let's take a look at the TWO facts they got wrong, and displayed to over a MILLION people.
now, instead of just GOOGLING TWO SIMPLE FACTS, THEY DECIDED TO JUST WRITE RANDOM SHIT.
ENOUGH WAITING - HERE THE THE TWO FACTS THEY GOT WRONG
picture 1: bitcoin up $900 in the last year? THE LAST MOTHER FUCKING, COCK SUCKING
.
.
.
YEAR?!?
WHY DO SUCH DUMBASSES HAVE ACCESS TO SOMETHING MILLIONS VIEW?
IT MAKES NO FUCKING SENSE
picture two: the actual fuck????
did i just read that?
b- bi- bitcoin will "run dry" BY 2032.
i think i finally figured it out.
these facts, they're literally just random number.
<thoughtBubble>
i can see it now:
wired employee 1: hey, guess what number im thinking of?
wired employee 2: 14?
wired employee 1: *screaming* BITCOIN WILL RUN DRY IN 14 YEARS
</thoughtBubble>
how do these people get hired. do they hire only hire 12 year old interns? im genuinely asking. does anyone know?
okay, end of rant. plz continue complaining about dumbasses who have power thru the media in tech8 -
Security is a joke. And people don't seem to get it. Especially Data mungers.
I've spent about half an hour trying to work out how to securely connect to power BI using PowerShell in a renewable manner for unattended access later on.
Every single example I've found seems to involve you storing $user and $password variables inside your script. If I'm lucky, they're going to pass them through ConvertTo-SecureString. And nobody talks about securely storing AD auth tokens, or using the Windows Credential Manager.
I know it's possible, but it's going to take me ages to work out how from all sorts of disparate sources...16 -
I've complained about this friend who I help out with a side project before and I don't know how to deal with this anymore.
He decided he wants to send out a free weekly newsletter with content that takes a lot of time to create.
He got burned out from all of the work. I tell him to only do it bi-weekly. Still doesn't listen.
He doesn't work, whereas I have a full-time job, his mom feeds him and does everything for him.
Someone on the newsletter said they didn't receive a newsletter they signed up for and now he's dumping that on me. I refuse to deal with it. I have paid a lot of my own money for the website he uses to post stuff. He knows more about the newsletter software than I do. The least he can do is deal with the people on Discord and the email newsletter issues, because I honestly don't have time. He has a solar generator at his house, so he can work through the power outages we have on a daily basis, I do not.
He keeps wanting to give out free shit to people, whereas I told him this side project needs to start making money to make it worthwhile for me. He's always making excuses that he doesn't have money, blah blah blah. We designed a cool magazine and it's pretty much finished, but now he's stalling with things he needs to do to get it published on Drivethrurpg.
He just hassled me again to check this gmail I made for him to use for the newsletter and this YouTube he wants to start. I told him, no I haven't had time.
The other day I went to his house to hang out, he gave me a taste of his home made ginger beer and I said it's great, but then he went and drank a pint of it without even offering me some, right in my face. His mom came out and asked me an hour later if I wanted tea. These people are weird. Maybe I am weird.
He also doesn't use the project management software I showed him how to use, so I don't know what's going on. And I told him this a couple of times.
Think I should tell this dude that I don't have time to work on this stuff? And how do I do it politely, yet sternly?5 -
So, the PowerQuery type system appears to be a Joke.
For those you that aren't familiar with PowerQuery, it's the ETL language that is used in PowerBI, and some other parts of the MS PowerPlatform. It was formerly known as the M Language.
The language has a type system, that includes records (think hashes) and tables, which are, for practical purposes, a list of records.
The wonderful M language specification document states that:
"Any value that is a record conforms to the intrinsic type record, which does not place any restrictions on the field names or values within a record value. A record-type value is used to restrict the set of valid names as well as the types of values that are permitted to be associated with those names."
Except that the restriction is only to the set of valid names, and the language interpreter doesn't throw an error when I place a number into a text field, but also doesn't do any sort of implicit conversion. This is all hunky-dory, until you then try to load the data into the Tabular Model that underlies the query engine, which does expect the values to be of the type that is specified, and it throws an error.
But PowerBI, in its infinite wisdom, doesn't actually *record* the error, it merely tells you the error exists, and tells you to go back to the query editor to list the errors thrown up by the powerquery engine. Which, as previously stated, doesn't throw up an error for this instance.
So I've spent all afternoon trying to work out why my queries aren't loading, because I have an error that doesn't exist. fml.
[You can follow this issue on the communtiy feedback site here: https://community.powerbi.com/t5/... ] -
That moment when you have to attend power bi introductory session but you already delivered 2 business intelligence solutions in a previous job.
And he doesn't even have a clue what he is talking about -
Power BI: wonderful tool, pretty graphics, and can do a lot of powerful stuff.
But it’s also quite frustrating when you want to do advanced things, as it’s such a closed platform.
* No way to run powerquery scripts in a command line
* Unit testing is a major pain, and doesn’t really test all the data munging capabilities
* The various layers (offline/online, visualisation, DAX, Powerquery, Dataset, Dataflow) are a bit too seamless: locating where an issue is happening when debugging can be pain, especially as filtering works differently in Query Editing mode than Query Visualisation mode.
And my number 1 pet peeve:
* No version control
It’s seriously disconcerting to go back to a no version control system, especially as you need to modify “live code” sometimes in order to debug a visual.
At best, I’ve been looking into extracting the code from the file, and then checking that into git, but it’s still a one-way street that means a lot of copying and pasting back into the program in order to roll back, and makes forking quite difficult.
It’s rewarding to work with the system, but these frustrations can really get to me sometimes2 -
Hey guys i need help, i want to switch to data field from react, i hv 2 yrs exp in react, should i go for data science? Can a frontend guy like me become a data scientist? And is the data science job fun when compared to react? Or should i go for power bi developer? I heard that power bi has a lot of scope as well. Thanks
