denimnerd42··on Get me out of data hell
I lead a team on a large data project at an enormous bank, hundreds of devs on the project across 3 continents. My team took care of the integration and automation of the sdlc process. We moved from several generations of ETL applications (9 applications) netezza/teradata/mainframes/hive map reduce all to spark. The project was a huge cost savings and great success. Massive risk reduction by getting these systems all under 1 roof. We found a lot of issues with the original data. We automated the lineage generation, data quality, data integrity, etc. We developed a frame work that made everything batteries included. Transformations were done as linear set of SQL steps or a DAG of sql steps if required. You could do more complicated things in reusable plugins if needed. We had a rock solid old school scheduler application also. We had thousands of these jobs. We had an automated data comparison tool that cataloged old data and ran the original code vs the new code on the same set of data. I don't think it's impossible to pull off but it was a hard project for sure. Grew my career a ton.

ah sad, tbh I haven't been in a store in years.

Denim in $150-300 japanese levis stye reproduction jeans is 50-100% heavier duty than department store jeans. 12-25oz per square yard vs 6-10 in department store. I get 3-5 years before I start getting holes. I do white collar and home improvement in mine. I imagine the toughest users would get 18 months-2 years before crotch or wallet/phone holes appear. Holes can be darned or repaired anyways.

The construction isn't always better depending on brand. Some maintain reproduction details like 100% cotton thread. But the denim is definitely better. The price is in the denim, details, and 3rd construction for most brands. Some brands have extremely high end in all 3 and those are the ones at $325+

denimnerd42··on Autossh – automatically restart SSH sessions and tunnels
been doing this since 2012... autossh wasn't the solution back then even.

you want ServerAliveCountMax too but default is 3.

denimnerd42··on Solar will get too cheap to connect to the power grid
there's the skin effect though https://en.wikipedia.org/wiki/Skin_effect

so high voltage DC is a better option

denimnerd42··on Rye and Uv: August Is Harvest Season for Python Packaging
the MS vs code python plugin being closed source is also a major bummer.

yes? my preferred desktop env is linux.

denimnerd42··on Comma.ai: Refactoring for Growth
i took the leap and it's been more than I could have wished for. i don't have a ton of miles, maybe 10k miles but no issues. it's just level 2 driving which is better than anything OEMs offer.
denimnerd42··on Comma.ai: Refactoring for Growth
you couldn't see yourself eating breakfast at 8 or 9 and lunch at 12-1 every day? two meals is a perk at my job and it's great.

one of my friends at another job with same benefit doesn't have kids so he goes to work at 11 and eats lunch and then stays for dinner too.

denimnerd42··on Why Discover is no American Express
yup just easier to use my bofa card which is 2.625% on everything (due to platinum honors preferred rewards which is "easy" to obtain with some >100k in a brokerage account - could be equities, CDs, money market.. whatever)

denimnerd42··on Wells Fargo Bet on a Flashy Rent Credit Card. It Is Costing the Bank Dearly
And the fees are basically pure profit while the interest payments have a huge cost and risk.
denimnerd42··on Wells Fargo Bet on a Flashy Rent Credit Card. It Is Costing the Bank Dearly
I don't know.. Maybe in the good times. They are highly risky though and require a lot of capital backing that may not show up directly on the P&L.

https://www.reuters.com/business/finance/bank-america-profit...

I guess I could look more into the 10-K and see if that information is transparent to the public.

denimnerd42··on Wells Fargo Bet on a Flashy Rent Credit Card. It Is Costing the Bank Dearly
I guess. Revolving credit is expensive for the bank to hold. They have to allocate a lot of capital to back the revolving unsecured debt compared to other secured loans. I think they'd rather just make money on the regular fees and not have to worry about people holding balances. By providing credit they can charge a higher transaction fee than a debit card so that's their value add. Retailers are willing to pay for that access to consumer credit.

That's why credit cards are so popular in America vs other countries. They can charge a transaction fee that actually makes a profit. If they are regulated to a low fee then they can't give cards to anyone but the highest of FICO scores because the debt itself is so risky.

denimnerd42··on Wells Fargo Bet on a Flashy Rent Credit Card. It Is Costing the Bank Dearly
I always assumed banks made money on credit cards from the transaction fees. I think the interest rates are mostly there to scare you into paying your bill. It seems like once a CC balance gets out of control the bank's ability to recapture that money is limited since the card is unsecured.

I guess they make more money off the people that use a CC as as a temporary loan and always repay but customers with that risk profile are generally one step away from never paying it off.

denimnerd42··on How Alexa dropped the ball on being the top conversational system
they want you to shop with your voice because there is a lot of friction if you then decide that's not what you really wanted. most people if they mistakenly order something with alexa will just let it be delivered, not cancel it.

same with using a mobile app to shop. you have less ability to cross shop quickly because the interface is inherently slower than a mouse and keyboard plus the OS multi tasking features are horrible. plus they get a lot more information about you with their app.

so it's not always that they think the feature is better for you, it may just be that it's better for them.

denimnerd42··on AES-GCM and breaking it on nonce reuse
The problem with a random nonce is that most implementations also use a nonce of 12 bytes which under some use cases might not be enough before you repeat a nonce. So to remedy this they suggest using a counter but this could be hard to implement.

When I use AES-GCM I just use a bigger nonce and use a random one.

Last time I used AES-GCM I had a really hard time getting the person writing the other end to not re-use nonces.

denimnerd42··on Apple unveils 'Passwords' manager app at WWDC 2024
i've thought of all kinds of iterations with varying levels of security. the phone with BT encryption would be fine in general but that would get picked apart for security if you actually tried to market it as secure.

the really secure way I was thinking is a small touch device that could be small enough to slide into your wallet or even as a device that would live in a phone case exposed on the back of your phone. then there would be a small yubi key like dongle that you'd plug in to whatever your target device is and it would communicate over wifi. that would be like the ultra paranoid version. then you could have the iphone/android app that communicates with the dongle, the one that uses BT encryption, the one that uses a USB cable from the phone to emulate a keyboard.. options are endless.

there's some features you could have like computer vision to recognize the login prompt. it's easy to get into an imaginative loop with the ideas.

Siri already has an optional text button on the lockscreen. They changed the shortcut though. For me in ios17 it's a long press on the side button.

The offline device with a plugin usb keyboard that "types" in your username and password is exactly what i've wanted forever. There are some devices people have made and posted online. I made a POC with an old android phone once but never got past that stage.

I investigated the bluetooth encryption and it didn't really seem up to the task. You could create a dongle that lived on wifi though that would do the same.

denimnerd42··on There Has Never Been a Better Time to Switch to Linux
If I could use gnome at work I would totally switch back to Linux full time. I used gnome 3 for years during HS and college but it was too jarring to switch back and forth once I had to start using Windows full time. The window management muscle memory is just painful.
denimnerd42··on If A.I. Can Do Your Job, Maybe It Can Also Replace Your CEO
My wife uses chatgpt for this. The only problem is the output might be better English and less grammar mistakes but it reads downright cringy to a native English speaker. I think it’s easily identifiable as being passed through an LLM too by anyone familiar with the usage.
