random5634··on Switzerland votes against electronic ID system provided by private companies
Prior delivery is not generally a major consideration in a govt RFP award.

This is in part because no score is ever released related to prior delivery (ie, no central assessment record), and attempts to include it get tied up in process issues (ie, rights to respond, litigation) or claims it is subjective. It also overlaps with govt agency disfunction around scope and requirements and no govt manager wants a failed project, so everyone just sweeps them under the rug and keeps moving. It is crazy though, you are literally hiring the same HORRIBLE firms over and over.

What is PARAMOUNT is that you be willing spend absolute metric tons of UNPAID time responding to RFP's, have enough money in bank to lose 4 out of 5, be willing to go through 2 year RFP processes, be willing to agree to every item on the requirements lists filled with further buzzwords and "standards". This does NOT attract high performing companies, no competent engineer would even put up with this / sit through this. So you get body shop type consulting firms, using giant java framework and other solutions, and everything is insanely siloed.

The crazy pricing is often justified because the hassle in dealing with these contracts from a contract admin overhead can absolutely DWARF actual deliverables, and nothing has to be logical (and sometimes is not).

My recommendations here would be either:

a) just pay to bring stuff in house so you get cooperation, develop open source apps and prohibit any scope creep outside of absolute minimum needed until project is in operation. EVERY freaking agency hangs 100's of new requirements they never even used before onto these projects - solutions can be undeliverable and unusable as a result, for example 40 questions PER VACINNE SHOT here in California is the height of stupidity to make these idiots feel important.

b) pay for actual use / adoption, and let there be a somewhat free market. A lot of time the users of any govt system have ZERO input. Oddly, if they let agencies find their own solutions on a smaller scale, whatever you lose in "efficiency" by not having the megaproject (hint nothing - mega projects = disaster in govt land) you would see some natural winning solutions start to bubble up. I worked with an agency with a totally fantastic contract management / invoicing system, and I kept on wondering, holy hell, they actually got it right. I started to see other agencies use it in neighboring govts - it was great - people really liked it (super easy use, allowed users to do the google, Microsoft etc login even which is unheard of) and it was fast which is also rare.

But then someone convinced the head tech folks they should stomp on everything with the new and improved people. They actually had to roll back the mega project for another year (after years of dev) because it didn't even cover a fraction of what old systems easily did.

The irony is Apple devices have BY FAR the longest useful life. The resale market is the best. The updates from Apple are the best. The devices flooding landfills are the “repairable” android devices. I have friends who’ve gotten ZERO updates after purchase!!

random5634··on Thanks HN: Lessons learned after Google nearly killed my site
Quick notes:

Site owner has not confirmed they screened all uploaded content for malware - this is a major issue these days and google and others will flag you if you host viruses and pump out malware.

And no - you cannot sue google to force them to allow users to be infected.

It’s not clear that all customer content is hosted on a separate domain, and each customer on a separate sub domain . Your reputation will be trashed pretty quickly if you host content on main domain blindly.

It’s not clear that all uploaded content is protected from being linked too or downloaded. Google admins and other virus vendors can setup screens on downloads.

Anyways - see plenty of shady / scam and incompetent website owners hosting malware - not much sympathy in most cases.

random5634··on Female Founder Secrets: Fertility
Yeah, my mom always rebelled at the feminist push to have women do men's work as the goal (without valuing work women already did). Join the military, kill people etc. I'm 100% for that, but it's crazy that a women doesn't get paid for raising kids, perhaps the most important thing for society and with INCREDIBLE costs (if done badly) and benefits (if done well) to everyone.

What's even more interesting, upvalue work that is traditionally female, and you may see more men drawn to it, staying home, teaching etc.

Instead, those can be thankless jobs from a money standpoint, and only folks who sell their souls into a male centric hellhole of work environments (PhD life is silly, medical residencies are nuts etc) are rewarded and women are told to lean in.

random5634··on Lion: A formally verified, 5-stage pipeline RISC-V core
My partner did hardware stuff. I couldn't BELEIVE how much time they spent in verification space (and how annoying it seemed and retro the tooling appeared!). Much different than programming where I can iterate 100x per day.

I get crashes with XMP, usually right at worst possible time on a zoom call where I am presenting! And saying users should overclock just seems weird, apple works out of the box.

For whatever reason, the overall memory system on the M1 systems just seems better than intel. I really wish I could follow more details from on-die cache to how memory is actually loaded / unloaded to speeds, but every time I've looked at it a little it just seems the M1 / Apple are doing it better across the whole stack.

random5634··on Every $1 of BTC value responsible for $0.49 in health and climate damages in US
Because the transactional ledger of bitcoin is what is driving electricity use, and another statement might be, for every $1 transacted on the bitcoin ledger, 0.0005 dollars in health damage is caused. (it's roughly a factor of 1000 more volume then new mining, and over time new mining is going to get smaller and smaller)
random5634··on Every $1 of BTC value responsible for $0.49 in health and climate damages in US
And neither is highlighting bitcoin, especially by focusing ONLY on the mining aspect of it. The use of the network is also part of the bitcoin story. If instead of using new bitcoins mined they did transaction value per day (ie, $20B+) the math would be totally different.

If you applied this same damage model to something people had fondness for (ie, driving an electric car) you'd realize we should be working as HARD as we can to kill EV cars dead, because there is a MASSIVE unaccounted for cost to charging them (using this model).

Reality though is bitcoin chases low cost power, and that is currently often actually green (hydro, excess solar during day when their is curtailment and negative pricing etc). I can't imagine the economics making sense to mine using coal power.

random5634··on Every $1 of BTC value responsible for $0.49 in health and climate damages in US
For every dollar spent building a train station there are $50 dollars of health and climate damages.

This ignores the USE of the train station, and just focuses on energy costs to build it.

This study is only focused on mining new coins. Heads up, some of the (wildly inflated) value of bitcoin is tied to (arguable) uses and the ability of the blockchain to operate as a non-repudiation public ledger that allows global transfer of value with strong guarantees totally independent of any other central party.

Some quick math.

1 bitcoin is lets say worth $50,000. Let's assume $10K in electricity to mine this. So for every $1 in bitcoin, you need 20 cents of electricity.

Reduced to it's simplest, the claim here is that for every 20 cents of electricity, there is another 50 cents of health impacts.

Fair enough, but if you believe this, then a lot of other things have huge damages.

random5634··on Every $1 of BTC value responsible for $0.49 in health and climate damages in US
It assumes the value of Bitcoin is in the mining of new coins. The network also has value as a ledger to record transfers of Bitcoin (billions per day) which contributes to the value of the network

The analysis can be generalized to say anything that uses 0.05 electricity creates these large harms. Perhaps true, but it’s not going to be unique to Bitcoin

If you think this “scientific” study qualifies as a contributor to intelligent discourse think again.

It memory on a SiP.

Taking a quick look at an i9 9900 ($382 for chip alone) it supports DDR4-2666. i9-10900T runs at 2933 - $400 for chip alone.

Apple is running their stuff at 4100 or something. So that looks faster. And the mac mini costs $700 including the insane apple margins?

Can you spec out the $700 machine on pc parts picker that shows that the M1 is nothing special? One with faster or equivalent memory.

Calling the M1 and $700 machine a HEDT?? Huh? Apple is going to sell these things by the truckload.

random5634··on Alamo Drafthouse Files for Bankruptcy
We don't do work with folks with a past due invoice. It works well. We can't engage on the next engagement until you pay the prior.

The folks who slow pay are a paint to deal with overall I've found, so no big loss when they go. Or you don't get paid, which is even worse! And yes, they will slow pay anyone who lets them.

random5634··on Tesla voids warranty if you try to power your home with your car
We don't know what they said. We are getting second hand knowledge. We know they wouldn't replace battery.

The standard approach here is warranty doesn't cover the part you damaged through misuse. So if you stab the car seats with a big knife, they won't give you new seats, but that doesn't void whole warranty.

Some things do void entire car warranty, those are pretty standard as well. Things like salvage title, submerged in a flood etc.

Others void out powertrain warranty or larger areas, usually pretty logical (flash cars computer with a tune, race car and destroy engine probably one of the more common ones?) Even though just engine may be obviously destroyed, you might lose warranty for entire powertrain (clutch / transmission etc).

random5634··on Tesla voids warranty if you try to power your home with your car
The power station uses four lithium ion batteries. That is different than a lead acid. The amp hours on these is at 20volts. So some quick math

9 Amp-hours at 20 volts is .18kWH x 4 batteries is .72 kwh. Not bad (though far below Tesla's battery which may be 100x that).

A good car battery might be 40AH at 12 volts or .5kWH? But if discharge rate is high you get less capacity.

Someone running a 2kW inverter, is going to discharge the battery in 15 minutes. Then you add Peukert constant [1] of 1.2 or so? Maybe half that? Then you realize you need to stay above 80% DoD? Even worse? So a 2kW continuous load is CRUSHING this battery. A light bulb is 100 watts. any type of motor / blower etc is going to be what would be considered a high draw.

When a refrigerator starts you may also be load spiking.

All this could damage the charging circuit to the battery which was almost certainly not designed for this load story (hopefully not)

You may be discharging at a higher rate then the desired charge rate, so just keeping an AGM charged at high draws may wreck it.

Plug in a 20W charger? No problem, the math says that should be pretty easy to handle. A 2,000 watt inverter? Short burst? No problem probably. Continuous - probably going to be a problem as the user found out.

There's a reason everyone refuses to replace these batteries used this way.

[1] https://en.wikipedia.org/w/index.php?title=Peukert%27s_law

Note - I absolutely think Tesla should support this use case, a 100kwh battery pack in your house for when the power goes out would be amazing. The the HV pack could absolutely support house loads for most everyone. You've paid 60K for the battery and vehicle, what a use case that would be! But they'd need to a different path probably through charging cable and the regulatory hassle could be annoying - pushing a lot of power back into household circuits - the liability etc risks go up (but could probably wire as if it were a generator with a transfer switch and islanding etc)

random5634··on Tesla voids warranty if you try to power your home with your car
The user damaged their battery by plugging in a 2KW inverter. Then they complained that tesla would not give them a free battery as a result. So it seems somewhat clear that Tesla denied replacing the battery in this situation
random5634··on Tesla voids warranty if you try to power your home with your car
This is super well established.

Let me 100% clear. If you kill your battery because you idled a car and hooked up an inverter then Ford will not cover this claim. That is misuse.

https://www.ford.com/cmslibs/content/dam/brand_ford/en_us/br...

"misuse of the vehicle, such a driving over curbs, overloading, racing or using the vehicle as a stationary power source".

Yes - you can do it. No, they do not have to pay for the damage you cause doing this. I've always known this.

This idea that you can do something that clearly caused damage in the linked article and then TESLA, not the owner of vehicle owes money is backwards.

A warranty covers use of the vehicle for intended purposes, not misuse. The user caused damage by misusing the vehicle, in fact, the very damage one would expect.

random5634··on Tesla voids warranty if you try to power your home with your car
The claim that the vehicle is warrantied for this absolute abuse is ridiculous.
random5634··on Tesla voids warranty if you try to power your home with your car
What in the WORLD!? This is a tiny 12v house lead acid battery. It is not designed or intended to be used as a stationary power source to POWER A HOUSE!

Warranties are for intended use. If I drop a boat out of a helicopter on onto concrete from 1,000 feet and it breaks, I can't make a warranty claim. This is SPECIFICALLY covered in the warrenty for TESLA's as well.

Now we are getting legal advice on HN that this violates the magnuson act! This is an only on HN comment.

This is not how these batteries are intended to be used.

Lawsuits like this are why we have crazy warning labels in Americas on things.

random5634··on Coinbase mafia shows how tight a circle holds sway over Bitcoin
Well described. There are folks going absolutely nuclear over these things - genatalia, perversions.

It's often tied to what appear to be intentional misreading's or overbroad readings of relatively innocuous statements.

"small circle of mostly men" turns into some sort of absolutist statement about bitcoin ownership, genatalia and perversions.

One reason to mention gender is that gender, and broader access by women in particular to tech is a current topic. So here you have a VERY male dominated space worth billions. While a women caring for a child at home get's paid nothing. I actually see some major issues in the way society rewards people, and the gender concentration mentioned in this story is interesting in that context.

random5634··on Coinbase mafia shows how tight a circle holds sway over Bitcoin
Actually - where I am guys is considered negative because it derives from male as the default gender / ie, patriarchal is the argument I've heard.

But absolutely NO ONE considers it a perversion or focus on genitals except for a few folks. This line, why are you focusing on my genitals or why are you focusing on their genitals comes up repeatedly in this context so it has to be a commonly used argument in some more activist circles.

That and focusing on "perversions" - which I find even weirder, most of the offenders are just normal people who didn't even realize "guys" was offensive or might be offensive to some.

Some of the activists who start yelling about perversions and genitals seem a bit more off their rocker at times then the folks they are accusing. The only thing that caught my eye was the perversions / genitals thing, because I'd just been reading someone else who used this same argument in a similar context.

random5634··on Coinbase mafia shows how tight a circle holds sway over Bitcoin
Haha. Doesn't work where I am as southern accents are seen as racist in a way - and also I'm not southern so would be weird on that level - but I like it if you were in the south!

random5634··on Coinbase mafia shows how tight a circle holds sway over Bitcoin
"Hey guys, want to get coffee" - is a historically common (and yes, now bad way) of asking if a group of folks, of any gender, want to get coffee.

The insistence that someone is focusing on genital's and have a pervasion when asking this really does seem like a projection on the part of the folks making that claim, and I have noticed the genitals things come up over and over now in this context - it seriously is WEIRD! Please read up on projection.

Many of us are married, with kids, and focusing on the genitals of work colleagues is the LAST thing on our minds.

I've broadened it in the past, hey guys and girls or hey guys and women - all less than ideal in my view, girls doesn't have same connotations as guys, and women or ladies feels awkward. Hey people works well in my view. But when a women says to me, hey guys, want to get coffee - I don't freak out on them with this type of focus on genitals / perversion language. I just say, sounds great - 5 minutes? And away we go very happily to chat about whatever issue has come up.
