Little help from you talented techies?

By HeadSet follow HeadSet   2020 Dec 15, 1:38pm 513 views   72 comments   watch   nsfw   quote   share    


Anyone on Patnet able to give me an idea on how to do the following?



I cannot figure this out in Access tools/VBA or Excel tools/VBA. I really just need to know how many days each cab was leased out for the month, and I think this grid is the way to do it. For example, a cab that was leased out from 1-8 Nov and then from 8-15 Nov was leased for 15 days. Output is any way to show Cab 1 for 24 days, Cab 3 for 30 days, Cab 6 at 4 days, and so on. I do not want to double count dates that overlap.

Any ideas, to at least point me at what logic to use? Does not have to be Access or Excel.

It went exactly as I described it off the top of my head further back in the thread.

I can still do this shit, I'm just disgusted where I'm at now. I work with a bunch of know it all non technical Millennials that poke their finger in every pie.
This project would have taken a month, and it would have came down to my first thought in the meeting, that was shot down by everyone else with no stake in actually doing the task. Software is not a democracy, let the damn people who know their shit, do their damn job!(A rant directed at my current situation not you).

If you have to much trouble, run this script then import the csv into it .

Or use it to name your table and column names

CREATE TABLE [dbo].[cabdata](
[Cab] [varchar](50) NULL,
[LeaseStartDate] [datetime] NULL,
[LeaseEndDate] [datetime] NULL
) ON [PRIMARY]

GO

@Headset The code I first pasted Patnet strips out the * and put a blank while it made the text in between bold.
or if you look at the 4th and 3rd line to the bottom in your picture, it says "Select (removed by Patnet) From" change that to "Select (asterisks symbol) From" in both of those statements.
I repasted the code, in post 30, recopy it then change the values to match your picture.
Either rename your column vehiclenumber to cab or change it in the script.

NO not at all, it was just a thought I had. As lately I'm so disgusted because everyone and everything is in the way of me getting my job done. When a problem comes up, that I would solve and turn around in minutes, hours or days. By time everyone has stepped on it and poked their finger in the pie, it's three months later, and I can't bring my self to even do it. I made that comment, because I have no desire to code for the last 2 years because of it. I wasn't sure if I'm burned out and a Dinosaur(in programming terms) or if was because I'm just disgusted with where I work and the turkeys I work with. Everyone thinks I'm busy as hell, but in reality, I'm waiting for all of the committees, and political campaigns to run their course to derive at the same conclusion I came at in the initial meeting, or in my response to their initial request.

Thanks for giving me something to do, I actually felt like doing.

Change jobs.

I burn out, I'm fucking crispy fried now. Everything is a roadblock. New job, fun new interesting, old job, boring stale and I'm just doing maintenance.

I worked at a company that I replaced myself with a script with. I was like "fire me please, you don't need me, this script does my job now" - they wouldn't. I was literally getting up every day wanting to die rather than go to work sitting in front of a computer running data through a script. It was a nightmare.

Next time I'm off, I'm taking 6 months off to do all the crap I've been wanting to do, but have been blocked at my job from doing. I can't work on two entirely different projects at the same time - I need time to concentrate on what I want to work on. When I'm sick of that, not only will I have a cool product, I'll be sick of working on my cool product.

Unless I have something to figure out, I hate my job. I need to have a challenge. Perfecting code is no challenge. Tweaking code is no challenge.

I want to go in business, either manufacturing or Restaurant. I only say Restaurant, solely due to the fact, that the Plandemic has wiped out a lot of competition that was in some of the most choice locations. There's a Diner near me that has been in my town since the early 50's. Jack's Diner.
Location is one of the most biggest drivers an eatery's success. I drove by it a few weeks ago, and saw a sign saying it was available. I got to thinking about it for a few days. Then drove by to get the info to inquire on it. I saw they had a website so I started there. It said it was fully functional rented as is ready to go, for a little over 5 grand a month. I thought that was outrageous. But I was talking to other people, who reckon pre Corona they had to be cranking out a couple grand a day. I drove by a few days ago, and it said, grand reopening coming soon. It's a great in and out location. Something like that could have worked. I wouldn't open a sandwich joint in an empty strip mall. This time last year, that's all you could find.

I think manufacturing will boom, if we have the right people in office, willing to bring our supply chain back. Maybe even farming,

Sounds like me a lot.

but I don't want to be in technology or programming. I'm tired of the pointlessness of it. No matter what you make and what you make it for. It will be obsolete in a few years. Libraries deprecated and OS they were written for end of life cycle.
I still drive by buildings I once put carpet or tile in(in my distant past career), its nice to see something that is still there. All of the cool programming shit I've done for companies over the last 30 years, I don't think one single one of them are still using any of it. Companies gone, or their whole infrastructure changed, changed ERP or CRMs. In fact, our company is in the process of moving everything into a cloud based drag and drop doohickey. They want me to help port programs I had to write the code for, because their business requirements and flow of the process, isn't something you find in drag and drop cloud based doohickeys. I'll help them the best I can, but the processes I wrote for them, wasn't even something they could port over to NetSuite, they tried for a year and half.

THIS is why I want time off.

30 years eh? What about bringing a bunch of stuff back? Remember ytalk? Remember when email ran on your computer? This cloud shit is just another way to censor and eavesdrop. It's another thin-client attempt. I'm disgusted by companies that say shit like "Google's terms of service say they will protect our data, and if they don't we can sue them". Yeah, good luck suing Google. Like when Dr. DOSS sued Microsoft, or Spyglass did, or Stacker did.

When people get burned, and they will get burned, it's going to swing back hard to private solutions in house. The trick is you have to drop a box in there, and it has to work.

None of this SLACK bullshit, no fucking Zoom, no Skype. P2P E2E encrypted, private, locally controlled systems. No GitHub, not even a remove server to run a website on. All inhouse, all completely controlled, totally monitored. Not hard to do, but time consuming to do.

We keep building newer, worse, less secure solutions that are not within our control. Corporations think this is cheaper and better. It is frustrating. When I was in college I worked on a DEC/VMS system that handled over 10,000 students doing work on it. We all had email, Usenet, could talk to anybody across the world. Unfettered access, no censorship, private accounts, later private webpages. I can do that on a raspberry pi now.

The absolute raw power we have today is mindblowing. The number of protocols that have been discarded is also mindblowing. There's a whole sea of "obsolete" tools to pick from. Imagine buying $100 box, plugging it in, and you have a server up and running that has all the capabilities of everything you access now. Why have a page on Facebook when you can just have a page on your box sitting at home? Can't censor that can you? Facebook won't "accidentally" change your settings so private information suddenly becomes public. No need for 3rd party trust.

TPB, I really appreciate the help, but there may be a tweak missing. For example Cab 3 was out from Dec 1 thru 5:

3,10/31/2020,11/6/2020
3,11/7/2020,11/13/2020
3,11/14/2020,11/20/2020
3,11/21/2020,11/27/2020
3,11/28/2020,12/5/2020 <<<<<<< (out from 28 Nov thru Dec 5th)

but the grid shows Cab 3 was out on Dec 5 only.

Also, Cab 3 above was out everyday in Nov, as were some other cabs, but none show on the grid to be out on any day that month past Nov 8th.

Hopefully this is an easy fix. Know that I appreciate you efforts so far, so can understand if you are tired of working on it. I know I cannot figure it out.

You should always build your own home control system, and if a company wants real safety and privacy they need to host their own HW and secure it. Of course it's not trivial since the cloud gives you automatic disaster fault-tolerance, but you would need to deploy and manage hardware at different regions. I don't think today's tech work is necessarily boring, the paradigm shifts are interesting, you can use lambdas or serverless container technology such as Fargate or you can use ECS. Of course every cloud provider has similar technology and there exist infrastructure-as-code tools such as Terraform which can leverage your coding and network skills onto any cloud provider. What's far more bothersome to many than the eternal shifting and refactoring which is just a sign of our rapidly changing times and technologies is the explosion in HR and political correctness and diversity, when proficient devs are laid off due to cost reasons but a "diversity" team is formed at the sane time. In that respect Covid actually was beneficial, I didn't mind the office for socializing with my favorite gang, but the intra-office PC and HR bullshit has significantly lessened since the remote era as it's hard to offend anyone from the confines of your home - just don't jerk off on a Zoom meeting like that clinton news network douchenozzle.

Thanks, Blue

Python is a bit above my skill set, but I will still try to load and walk through that anyway. What TPB did works, and although I never could have written that code, I understand SQL enough to use and modify it.

And thanks again guys. Automating this task with 5 Fleets of cabs will save a ton of work.

I am currently actively using TPB' s SQL solution, and it works great. I am also looking over what Blue produced. Therefore I no longer need a solution, but I appreciate that you would have put forth the effort.

No problem. I have the solution basically done, but it requires multiple steps. I took your spreadsheet, turned it into a csv file, used perl to convert the dates to the number of days from the beginning of the year (1-365, sometimes 366 if it's a leap year) made an array for each cab that was filled info for the days it was leased out, and then stopped at converting it back to months/days - but that's what I had left to do, but it seemed you had a solution and it's frankly less messy than my solution.

It was limited to working on 1 year at a time.

Fun side project. Just wanted to make certain you were set, because it's not much work to complete it - but it's work to use it.

Yes it was a fun exercise I would recommend anyone giving it a go, just to sharpen their skills. Date manipulation is always a mad skill, you don't need until you need it.

The drawback of the solution I created. It creates a list of past dates going three years back. Where as before I was getting the count of days in the range provided in the dates, and then had to create dates out of that range. I would have had to account for Leap year and other special considerations. So that script would have grown as bugs became apparent.
The second solution just generated a dynamic list of dates, so I didn't have to worry about it. As it allowed the SQL built in GetDate figure out those dates.
So if someone needs this script for booking a range of dates in the future, then they should go with my first solution.
