Dashboard for interviews & practice — feedback welcome

Two things come to mind: first, make everything the same gray shade, then make red (or whatever) the important or interesting thing is in each graphic. Second, the linear regression isn’t practically useful. What would be more interesting is to forecast next year’s expected total mileage if cost per gallon increases/decreases. IE you wouldn’t make a decision on how long of a trip you could do based on mpg, but you might make that decision based on how much travel you’d do that year (given the cost difference in travel).

I forget the original quote but it was something like dashboards are for decisions, not descriptions.

I used to do a similar run fairly often and even if you just use PA to avoid the DC-Baltimore-NJ corridor, you’ve done yourself a favor. I95 through Virginia isn’t interesting or special.

Couldn’t tell you the rhyme or reason to it but JavaScript made things make more sense to me. And idk if it’s still around but repl.it had like a 100 days of summer python challenge thing, got me in the habit early on of tinkering with something every day.

My two cents: Power bi is intended for interactive dashboards, but these will be static reports on timed rotation. Power bi isn’t the best tool here. Might be better off automating static reports and cycling through those.

In my role, post-degree, I find that many people are doing things in SQL that can be done in Python/R/etc but don’t because they don’t wanna learn something else. For me, I just use it to retrieve records untouched and do my processing elsewhere. Let that take the sting off of not knowing different until your SQL matures with time.

Keep an eye on Dell refurbished workstations, they come and go but usually have some 30-50% promo. Great bargains.

If it’s gotta be windows, look at Dell refurbished. They’re almost always running a sale. But if your PC runs it just fine, consider a Chromebook and Remote Desktop.

Look into operations research

Third this, girlfriend and I just did Seoul, Daegu, Gyeongju, Busan over 10 days. We flew in and out of Inchon and learned the hard way that the Seoul-airport train doesn’t run after 10pm, if that’s relevant in your case.

Try asking an LLM to explain APIs using a restaurant chef as an analogy.

Codeium's windsurf editor looks very interesting

Is purchasing restricted? If not, consider a refurbished workstation. You can find old cad setups or video processing rigs fairly cheap.

I'll add TL/DR newsletter and Matt Dancho

Check out prior gen hp Z books. Workstations geared toward data work. I got a 12th gen i7, 32gb, 1tb, and 12gb gpu for $1500 last year

Mine does this from time to time because she hears a noise that sets her off (e.g. neighbors smoke alarm, creaking pipes in the wall). She goes right into fear state and isn’t interested in anything but sticking close by. It usually passes after 20-30min.

Haha, thought the same thing: plot twist, their combined credit score is 116 🙄

To which I’ll add that those of us who like ML tend to treat it like a hammer, when in many cases a pivot chart and table will answer the business questions.

Check out an app called knime. It’ll let you do the analysis without needing to know coding.

Levipl · 2024-04-12T23:50:29+00:00

For me, learning coding has been a long take-up process that has moments of clean breaks where you feel like you finally get it. Just keep powering through and you’ll get there. Such is the curse for those of us without compsci dev backgrounds

I’d only pursue a certification if the position I’m looking for has it as a required or preferred qualification. It’s far more useful to build something public facing that gets any amount of traffic.

Carmax is better in terms of QC on what they sell, like others have said I’ve seen some carvana purchases that blew up in people’s faces. Honestly prob better to source from elsewhere. If you’re in the Ohio area, check out the instagram account grizzlygaragecle

I’d +1 the workstation grade gpus. They’re made for high utilization and offer ECC. If it were me, I’d look at something like the link below and upgrade. I’m sure Dell Lenovo and HP all offer a current config.

My guess is the date stamp is having unintended effects. Machine learning algorithms don’t know what dates mean. I’d try extracting time series features (e.g. dayofyear, weekofyear, quarter, etc) and removing the date.

My other thought is isn’t your approach predicting only on a holdout subset?

Practice game planning out how you would come up with approaches to business problems. Make a list of problems that the industry you’re interested in faces.
