Casteil··on The iOS option to charge battery to "80% Limit" shouldn't just be for iPhone 15
That's the original intent, but there's nothing stopping you from enabling it whenever to try to get the absolute max possible out of your battery. Low power mode does sacrifice quite a bit of functionality by default though.

Personally, my 15 pro can do >72 hours on a single charge WITHOUT doing stuff like this, even starting at 80% (note: mostly standby, no always on display, with ~3h screen on time total). The 80% limit is definitely something I'll be using virtually all the time.

Casteil··on We are retroactively dropping the iPhone’s repairability score
> You're already being mugged

A lot of phone thefts are quick pickpocketing/snatch-and-run, or snatch-off-a table, not some Hollywood "stick-em-up, give me everything you have" type of situation.

People target expensive phones, period.. but having fewer ways to turn those stolen phones into enough money to justify the risk means people will be less inclined to directly target them (especially when other brands' expensive flagship phones may be easier).

Similar concept in general physical security/theft deterrent, really.. put up a bigger challenge than others in your vicinity and you're less likely to be targeted.

You do know that a lot of people travel for work, right?

It's just one of many great aspects for such a capable device.

They also run very cool and are effectively silent even when the fan DOES eventually turn on for a sustained max load. By comparison, every Windows/Intel laptop I've had over the last decade exhibited obvious fan noise every time there was some short-lived load on the CPU - that includes several nicer business/pro grade laptops including Dell XPS, Latitudes, and a Thinkpad.

...and NONE of those other laptops came remotely close to reliably lasting 10+ hours on battery like the MBPs can/do.

Err, mobility? M1 / M2 Pro MBPs pack a serious punch... and they don't have to sacrifice battery life to do so - they smoke virtually all other laptops in terms of battery life.
Casteil··on Heat Pumps – The Well-Tempered Future of A/Cs
Similar climate here, although days it gets below -10f / -23c are uncommon. Most winter days in a climate like this you could heat with a modern/high tech heat pump, but:

- It's probably going to be more expensive than heating with natural gas if you're in the northern US - at least as things are today.

- A modern/high tech heat pump capable of heating when the outdoor temp is < 10f / -12c is likely going to be quite a bit more expensive than a standard AC unit - making it even more difficult to justify financially

- A natural gas furnace can keep you warm (and keep your pipes from freezing/bursting) even if there's a power outage. It doesn't take much of a generator to run a furnace/blower fan.. but good luck staying warm with ONLY a heat pump in those circumstances.

The one thing that can really help improve the financials of getting a heat pump is if you intend to install solar power at some point in the future. Depending on your power company, you may be able to generate enough credit in summer with excess generation to pay for heat the entire winter. I'd still go with a heat pump AND gas furnace for backup though.

Casteil··on Tesla Fleet Telemetry
Exactly. People shouldn't have to worry about their car being a serious privacy risk.

Video footage being shared with/accessible by Tesla should be strictly opt-in - especially for "sentry mode", which is the most likely to catch someone in their skivvies (or worse) in their garage.

Casteil··on Tesla Fleet Telemetry
>At Tesla we believe that security and privacy are core tenets of any modern technology.

Seeing this after the whistleblower/leak regarding Tesla employees having unfettered access to onboard camera footage (and that embarrassing/compromising footage of customers was actively shared internally) is... rich.

"Usually"

Not sure I'd trust my only copy of something I want to keep long term to a "usually."

Casteil··on To save money on insurance, drivers agree to intrusive monitoring technology
Frankly, it's exhausting to try keep your life private. The sheer number of different ways your privacy can be violated via modern cars, phones, computers, social media, surveillance/facial recognition, IoT devices (including 'smart' TVs), etc. is quite staggering.

Definitely seems like a losing battle. My retirement plan is a remote cabin in the woods.

Casteil··on Had a call with Reddit to discuss pricing
Yep, Twitter is currently enjoying this effect of having no "close 2nd" choice for their user base to defect to.
Casteil··on Had a call with Reddit to discuss pricing
Yes, please! We need alternatives to the social media giants that are now obviously bent on monetization and other, shadier motives.

Moves like this are what caused the huge Digg -> Reddit exodus that significantly boosted Reddit's popularity. People need other places to go when their favorite platform takes this seemingly inevitable path.

Casteil··on Syncthing: A continuous file synchronization program
It is pretty nice - I've been using it for over a year to sync files between my Windows desktop and 14" M1 Pro.

I've only come across a few hiccups:

- Sometimes MacOS updates "break" Syncthing (fairly easy to fix, just have to re-authorize permissions)

- Sometimes you end up with a (large) file/folder syncing that you don't want to sync.. Trying to sneak in an ignore rule after the fact and delete the file/folder from the device you don't want it on? That usually doesn't go over well.. I usually end up having to pause sync and fix the resulting conflict manually.

Casteil··on Gas-powered leaf blowers: The end is nigh (2021)
Nice to see proof that, while still quite loud to the user, multiple tested battery blowers fall off to reasonable levels by the time you get to 100-200ft which is a pretty typical distance for neighbors in a lot of areas.

Key takeaway regarding gas blowers: "Noticeably louder to 4 times louder"

Casteil··on Hawthorne effect
That sounds like a great way to lose good employees.
Casteil··on Intel Foundry Services and Arm announce collaboration on SoC design
To throw a similar experience into the mix... I agree on all counts, particularly around silence & efficiency - especially on the MBPs where the fans will actually turn off when not needed.

I've been a long time Windows user (20+ yrs) and have built my own PCs for nearly as long. My most recent 5900X + 3080 FE setup with 2x Gen 4 NVMes is amazing, but it's not the most efficient. ~95W idle and can top out around 200-400W depending on the use.

The (base) 14" M1 Pro I got launch day has been great overall, just really smooth/snappy in real-world use, where lately I've hit snags on Windows and MS software. The 14" M1 Pro maxes out around 35W or so (including its display). Desktop's more like 500W including displays. Great battery life on all the new M1s, it can do a full day at 8-14+ hours of medium/heavy use depending on your use/multitasking. It doesn't have to throttle down for thermal or power reasons like many recent Intel laptops (including a previous and recent-gen XPS 15 - which was much noisier by comparison).

In terms of quietness, I have the 3080 FE undervolted to typically only top out around 240W with under 2% performance loss. It typically runs around 55-65c in games without the fans being noticeable. 5900X is cooled by a 240mm AIO so it too is able to maintain reasonable temps running nice low fan speeds - only up to around 1050 RPM for sustained max loads which is still quiet compared to most other peoples' desktop PCs I've seen.

The 14" M1 Pro has never been audible above the idle fan speeds on the desktop (which run at ~550-600rpm and are also nice and quiet). The MBP is virtually always silent unless you manually crank the fan. Direct sunlight or somewhere very hot the fans might kick up a little more in response, but for me it's never really noticeable or even on or audible under normal use, and I like quiet devices.

Casteil··on Walmart to add EV charging to thousands of stores by 2030
...not until more EVs are available in the $20-30k price range. Most people can't afford new vehicles @ $30k+
Casteil··on Flipper Zero banned by Amazon for being a ‘card skimming device’
It's mind boggling how they just decided to throw basically any semblance of security completely out the window by putting NFC on credit cards for convenience.
Casteil··on SpaceX closing in on first Starship Super Heavy launch
Essentially, environmental/safety checklists... but it seems unlikely they'll get browbeaten because they're pretty critical to US space superiority.
Casteil··on State-of-the-Art Chatbot, Vicuna-7B, now runs on MacBook with GPU acceleration
This has been my experience so far as well. GPT4All feels pretty fragile with all its dependencies.

Anyone here who's used both this and GPT4All? Any thoughts/input on how they compare?
Casteil··on Programmer interrupted: The cost of interruption and context switching (2022)
>If you're having a huge issue with this, I suggest trying to find ways to hold less context at one time.

For many who experience this regularly, that basically means leaving/finding a new job.

With many employers, it's very difficult to escape being spread thin once you've proven your competence and they lean on you hard as a result.

Casteil··on Starlink internet is going from rural savior to unreliable luxury
>I replaced our Skymesh (geo-stationary) satellite (the only barely viable alternative) two years ago with Starlink. Skymesh gave me ~600ms RTT to Sydney servers, and maybe 25Mbps down (at 3am, clear sky, etc). Data cap was around 120GB / month, IIRC. Pricing was probably 75% of what I'm paying for Starlink now.

...what about Starlink's performance over the last 2 years?

Casteil··on SpaceX moves Starship to launch site, and liftoff could be just days away
Progress/change can be slow (if not effectively impossible) in organizations with decades of established bureaucracy and politics.
Casteil··on Original Prusa MK4
IMO, yes. I used octoprint for 3+ years before switching to Mainsail a month or two ago. Seems more polished, and haven't had as many problems with updates/slow updates as I did with OctoPrint. Probably won't go back.
Casteil··on Original Prusa MK4
To add a few things:

- Start your journey with PLA, and small prints. PLA is the easiest/least fussy material to print because it doesn't tend to string, or warp/shrink/lift off the bed like PETG/ABS. Nothing's worse than having a large print fail (usually boils down to slicer settings, hence the need to get familiar with your printer via smaller prints first).

- PrusaSlicer is, IMO, one of the best slicer options out there... works for virtually all printers and it's free/open source: https://github.com/prusa3d/PrusaSlicer/releases

- TPU filament is AMAZING to have for functional 3d prints... but you need a direct drive extruder to be able to print it reliably. If you can afford it, shoot for an Ender with a direct drive extruder e.g. the S1 or S1 Pro.

- Other stuff: Use Mainsail on a Raspberry Pi or similar for remote control/monitoring from any browser or phone (alternative: Creality Sonic Pad), Klipper firmware for GOING FAST (pressure advance setting), print mods/upgrades for your own printer (e.g. webcam mount, tool holders, parts cooling fan ducts, etc)

Casteil··on Gpt4all: A chatbot trained on ~800k GPT-3.5-Turbo Generations based on LLaMa
Do you know how their "spot pricing" works, exactly? "lets you use spare GPUs" doesn't tell us much. Is it granular to how long the duration the model is actively processing your prompt? ..or do you get dinged for an hour immediately and again on the hour?
Casteil··on Will wealthier people access better AIs?
They'll typically have an IT guy that handles things for the family. They'd be the one to set up call-forwarding and/or another tidy way of handling multiple numbers via one phone. Haven't done it myself but I'm sure there are numerous ways.
Casteil··on Ask HN: What is a specific use of GPT-4 that you think is remarkable?
One thing you can do for quick research -> summary is ask it to produce a detailed mind-map of the topic at hand, along with related/relevant long-tail keywords. The latter is effectively a SEO strategy in a nutshell, but having those keywords in front of you can really jog your memory.
Casteil··on Show HN: Briefsky – a free Dark Sky clone for multiple weather APIs
100% - I love https://www.windy.com for this very reason. Their full meteogram gives you a really succinct/concise representation for all the data it's showing every 3h for 5+ days (wind, temp, dew cloud cover/levels, etc).

That said.. Windy's precipitation forecast figures haven't always been great around here.
