When I loved in Guam we had a joke bout this:

How do you tell if someone is driving drunk?

They are driving straight!

With the unspoken part being anyone NOT drunk was weaving to dodge debris, potholes, etc.

No? Any M5 Max with the upgraded GPU has the full bandwidth, which includes the 48GB model the original poster mentioned. Same as the M4 Max, where only the trimmed part had a lower bandwidth.

Why are you throwing in extra cost for something thats not necessary? I know multiple people with 128GB Macs and none of us upgraded the storage. Especially not on a Studio (which isn't currently available).

I will say that their $3k number is off. I somehow missed that, and its too low.

$4.8k for 48GB Max (what the parent said). Half of your quote.

Even a 128GB is $6.8k today. Still only 2/3 your quote.

Bandwidth is relevant (I have both a 5090 and an M4 Max 128GB Studio, so have direct comparison right here), but quote the cost appropriately!

I won't try because I did something similar. If it happens I can guarantee that the insurance companies won't be solvent.

Instead we are focused on investing our money as a form of self-insurance.

It's kind of like life insurance; term makes sense but whole life doesn't (vs investing the premiums).

As far as polymarket: I can't say there. I've never used it (though I know what it is).

For poking at things "not directly in your responsibilities."

I was writing a program to do some remote drive upkeep and realized I needed permissions I didn't have, but could use a built in tool to do them. Then realized that meant I could take another step and use a human interface issue to gain more privilege if I wanted to.

Built a proof of concept on my personal machine at home, checked that it worked, reported it upline.

I never executed that code on our work systems and would have ended up in jail if I had. But even writing it nearly landed me there.

Well I guess that changes the keep vs sell calculation on my 128GB Studio. Have already been thinking about downsizing; seeing what the prices are now I may go ahead with that.

Absolutely awful timeline where the value of a PC goes up with time.

Safari for most things, Chromium if I have to for something.

I didn't toss those there because those (and IDEs and SSH/Terminal clients) are very opinionated and everyone has their favorites.

Heres my list:

Transnomino (https://www.transnomino.com/)

StillColor (https://github.com/aiaf/Stillcolor)

SublimeText (https://www.sublimetext.com/)

Homebrew (https://brew.sh/)

VLC (https://www.videolan.org/)

Macs Fan Control (https://crystalidea.com/macs-fan-control)

Rectangle (https://rectangleapp.com/)

NetBird (https://netbird.io/)

Obsidian (https://obsidian.md/)

Honestly its not huge and most are probably obvious, but those are what I immediately install on my machines. Looking forward to seeing alternatives or new must-haves.

I've posted that to HN before and it never gets traction. It's too bad; it's an excellent resource.

This is actually a topic I have deep experience with.

I wrote both test bench and aircraft code to replace an F/A-18 (C/D) chip in the RPYC (Roll Pitch Yaw Computer) due to the original being NLA. If I recall correctly (this was a couple decades ago now) the new chip was NEARLY a drop in but had a slightly different rise/fall curve and a couple of ns faster response. It was the closest I could find but required software updates to both the aircraft and the test bench to not be an issue.

So yeah, this has been an issue for decades. I'm personally glad to see a company addressing that market.

Not a surprise. I got in a LOT of trouble for identifying and outlining a trivial privilege escalation attack that worked on both NIPR and SIPR.

In the end I got to help write up the issue but to my knowledge they never patched it as it would have caused major issues with maintenance by closing off access needed for some legacy software patches.

My favorite phone of all time was my Nokia N9.

I would absolutely have another if there was an updated one.

Skiing is another one like climbing. Its only recently where higher volumes and wider forefoots are available, and they still try to tell you to go a size down.

Finishing up the same thing. 2x OS2 pairs with 2x CAT-6A to each drop, all coming together to the network closet.

Gives me fiber for bandwidth and copper for PoE. Figured it was smarter to do both than compromise to either one, and surprisingly the fiber was cheaper than the copper to pull.

Played it a bit on iOS. Great job!

Love the constraint you gave yourself with the zero asset files. Would love to see how you went about doing that.

That just gave me flashbacks. I wrote code on some ancient stuff that operated like you describe InterComm. Haven't done that in years, and I don't think much of anyone uses those systems anymore (Harris H100).

We've been dealing with this exact issue with Flovent for my son.

Amusingly our insurance's captive/preferred pharmacy wants to mail us the generic for $40 + 25 S+H instead of us buying it locally for $150. Except that they can't climate control the shipment and it's 20F over the rated temp of the inhaler here today, in the shade. So their in house pharmacist allowed an override.

Still a royal PITA.

Thanks for that. Thats what I thought, but havent implemented.

This is where I show my ignorance.

I'm coming to modern software development late. My experience was in things which were in the mini-computer and COBOL genre of machines, or on things that were so tightly controlled that the review process for one change could take a year (combat aircraft and drones).

So CI/CD is something I'm actually trying to grasp because it feels so alien to me.

All that to say: Don't currently have any.

Very interested in the answers, as I'm in a similar situation.
