desdiv··on Apple sues NSO Group to curb the abuse of state-sponsored spyware
In the clean room reverse engineering case:

1a. one team examines the device and products a detailed specification of it

1b. another team works solely off that newly produced specification; this team has zero contact with the actual device

In this hypothetical case:

2a. a third party affiliate accepts the Apple EULA, and gives the Apple IDs to NSO Group

2b. NSO Group uses the Apple IDs as credential to obtain Apple services

Notice that in case 2b, NSO Group has actual contact with Apple in two ways. They used Apple IDs, and that they obtain Apple services. This didn't happen in the reverse engineering case.

desdiv··on Analog Devices AD1139
Some context:

>The AD1139 is the first DAC offering 18-bit resolution (1 part in 262,1441) and true 18-bit accuracy in a component size hybrid package. A proprietary bit switching technique provides high accuracy, speed and stability without compromising small size or low cost.[0]

Just curious, I looked up the price:

Digikey, 1 unit: $2,449.80 USD [1]

Analog Devices, 100-499 units: $1706.58 USD

Analog Devices, 1000+ units: $1706.58 USD

desdiv··on Renesas enters FPGA market with the first ultra-low-power, low-cost family
>The pebble time used a small FPGA to act as a display controller for their custom ePaper-like color LCD display.

Minor correction: the pebble time uses a standard off-the-shelf Sharp Memory LCD display[0]. These displays are commonly used on smart watches so they're not propriety to Pebble. Sharp ships these displays as complete modules, with all control logic built-in, so you just need to supply power and serial commands to drive them. Any standard microcontroller can drive these.

You're right that Pebble chose to put an FPGA between their main microcontroller and the Sharp Memory LCD though.

desdiv··on What caused all the supply chain bottlenecks?
>Say you bought a vintage car -- do you have to pay more sales tax each time the car appreciates?

Some states and countries actually do tax personal property like cars. Virginia and Rhode Island, for example.

In those jurisdictions, if you have a vintage car in 2021 worth $100k, then you pay $100k * TAX_RATE in 2021. If the value of your car jumps up to $200k in 2022 (due to a movie or something), then you pay $200k * TAX_RATE in 2022. As long as the property is still in your possession, you pay property tax on it.

desdiv··on Lab-grown meat may never be cost-competitive enough to displace traditional meat
Methane has more than 10 times the warming potential of carbon dioxide.

That means if the grazing plants capture 1 mol of carbon dioxide from the air, and then is consumed by cows who turn some of the carbon into methane, then the warming potential of the system has increased even though it's still carbon neutral.

desdiv··on TikTokers Are Trading Stocks by Copying What Members of Congress Do
>Would they forced to sell their stock?

No, the proposed legislation does not affect your existing holdings you had before you become a Member of Congress, as long as you don't touch those holdings during your term of office.

"Members would also have the option of retaining their existing investments while in office, so long as they do not trade them while in office, or transferring their holdings into a blind trust. [0]"

>Does this apply to an S&P 500 ETF, if so, why?

No, since the S&P 500 is not an individual stock. All broad-based investments are exempt.

desdiv··on The Air Force Has Been Trying to Kill the A-10 Warthog for 14 Years
The US army is restricted from operating fixed wing aircraft heavier than 5,000 pounds due to the Pace-Finletter MOU of 1952[0].

I agree with you that both the air force and the army would appreciate and gladly cooperate with such a transfer, if it were possible. But in this case, both of their hands are tied.

Thank you. I did not know that before.

I've corrected my OP.

>You're from Quebec and don't feel at ease using only French words? Don't worry! French Rust is fully compatible with English-Rust, so you can mix both at your convenience.

Interesting factoid: in France, most of the stop signs say "stop" due to the Vienna Convention on Road Signs and Signals linked below.

In Québec, on the other hand, most of the stop signs say "Arrêt" due to nationalism reasons. Bilingual Arrêt/Stop signs exist, but are rare.

desdiv··on Canada aims to block Chelsea Manning from entering country
Here's the timeline of events (AFAIK):

1. On 2017-09-22, Ms. Manning attempted to enter Canada but was denied by the border guards. [0]

2. On or about On 2017-09-25, Ms. Manning received a letter from the Canadian government detailing why she was previously denied entry.

3. Ms. Manning and her lawyers files an appeal to the Canadian Immigration and Refugee Board. A tribunal hearing is scheduled for 2021-10-07. Let's call this hearing "Hearing A".

4. While Hearing A was still pending, the Canadian government allowed Ms. Manning entry for a few days into Canada in 2018.

5. Both sides (the Canadian border official side and Ms. Manning's side) are able to argue their case before Hearing A. The title of this news story refers to the fact that the border official side plans to put forth an argument in Hearing A.

desdiv··on Kei Car
From the Wikipedia article, it sounds like a modified EU-compliant variant is coming to EU.

>In 2021, a Latvian-based company Dartz (known for their armoured SUVs) announced a plan to sell the Hongguang Mini EV as the Dartz FreZe Nikrob, with a starting price in certain European countries at around €9,999 and assembled in the EU by Lithuanian company, Nikrob.

desdiv··on My Tungsten Cube (2019)
>Tungsten carbide is not heavy at all. Pure tungsten is twice as dense.

Tungsten carbide: 15.63 g/cm3

Tungsten: 19.3 g/cm3

Pure tungsten is about 1.23 times more dense, not twice as much.

desdiv··on Costa Rica signs law to attract digital nomads
Suppose you have a reliable generator system and your own house's power has reliable uptime. Would the internet still function during power outages? (The upstream telco equipment might lose power during an extended outage.)

Another HNer mentioned Costa Rica's internet connections during power outages, hence my question: https://news.ycombinator.com/item?id=28169281

desdiv··on Dropbox Engineering Career Framework
I see what you mean now. Sorry for the misunderstanding.

It's possible that they "bumped up" the intern and junior titles all into "Software Engineer" as a form of title inflation.

desdiv··on Dropbox Engineering Career Framework
From that page, I'm seeing 7 SWE levels from the sidebar:

- IC1 Software Engineer

- IC2 Software Engineer

- IC3 Software Engineer

- IC4 Software Engineer

- IC5 Staff Software Engineer

- IC6 Principal Software Engineer

- IC7 Sr. Principal Software Engineer

(This is on a desktop browser. Maybe you're only seeing 4 levels because you're on a mobile browser and the rest is cut off. Or maybe you indeed saw 4 levels and the site has been updated since your post.)

Hey there, cool service. I signed up immediately.

>You cannot have more than $50 in credit at any time.

Just curious, why a $50 limit? I'm the weird kind of guy who likes to pay years in advance. If possible, please consider raising this limit to $100 or even $200.

desdiv··on Show HN: Cimbar – File transfer via color barcodes and the Android camera

Decoding needs the Android app.

desdiv··on Violence breaks out at Wistron Corp’s iPhone manufacturing plant near Bengaluru
What you are talking about is a salary renegotiation, i.e. the employer offering the employee a new contract at a lower salary for work to be performed in the future.

What had alleged happened in the story is salary theft, i.e. the employer stealing part of the employee's remuneration for work already performed in the past.

I can't speak to India's legal system, but if this had happened in the US then it would be a federal crime under the Fair Labor Standards Act.

desdiv··on Coinbase Pro Disables Margin Trading
To be fair, if you brought $50 Bitcoins in 2013, you would have 380x your money today by doing nothing.

I'm sure your trading strategy is sound, but it's still a lot of work over the years to get the 500x gain, vs the 380x gain from just doing nothing.

(This comment is in jest. I realize "500x" is a figure of speech and not meant as a literal claim of performance.)

desdiv··on Casio F-91W: The strangely ubiquitous watch (2011)
Thank you for that bit of trivia. Very interesting.

>U.S. President Bill Clinton owned and wore several early models (including the original) of the watch during his time as Governor of Arkansas and in the early years of his Presidency. In one of his early Presidential photographs and at his 1993 Inaugural Ball, he is seen wearing a blue and black Ironman Triathlon. Clinton's forgoing of a more presidential watch such as a Rolex earned him some criticism; Gene Weingarten of the Washington Post described Clinton's timepiece derisively as “a plastic digital watch, thick as a brick and handsome as a hernia”, while Omega SA ran ads in 1992 suggesting that Clinton should give up the Timex in favor of something more expensive. Clinton stopped wearing his Ironman publicly in 1994, starting with the 50th anniversary of D-Day.[2][3] Clinton has since donated one of his early Ironman models to the Smithsonian.

desdiv··on Paying ransomware demands could land you in hot water with the feds
Yes, I should probably clarify: the point of such a law is to _discourage_ the behavior, but not to actually _punish_ the ransom payer, since no jury is going to vote on putting grieving parents in jail. So you end up deterring ransom payments without actually introducing negative externalities.
desdiv··on Paying ransomware demands could land you in hot water with the feds
>the US Treasury Department should impose fines on parents who want to pay the ransom for their kidnapped children

Some countries does actually criminalize paying ransom for kidnapped children. The logic being that if society make it harder to pay ransoms (both via criminalization and strong currency controls at the bank), then less kidnappers will get paid, which leads to less kidnapped children (hopefully).

The vast majority of people in this thread probably disagree with such a law. I certainly do. But on the other hand I realize that if I had been born in one of these countries and lived there my whole life, I would probably be a fervent defender of such a law.

desdiv··on Nikola Denies 'Fraud' Allegations, Threatens Legal Action Against Short-Sellers
>The Badger pickup partnership seems relatively safe for GM. At least the traditional electric one.

>At the very least they are getting an aesthetically pleasing exterior design and a ready email list of potential buyers.

Is a pickup truck exterior design and a customer list worth the 3 billion in market cap that GM lost since the news broke?

GM may not take a monetary damage from dealing with Nikola, but they will still suffer a reputation damage. If and when Nikola folds, GM's management will be seen as hilariously incompetent for not doing the proper due diligence, and the market will price that in accordingly.
