sf_rob··on LastPass user vaults stolen in recent hack
Honestly, URLs are a potentially massive threat vector themselves.

Are the urls associated with individual users either directly or in a bucketed fashion? Seems like no to the former but the release leaves a lot to be desired.

sf_rob··on Should I step down as head of Twitter? I will abide by the results of this poll
Likely and somehow even worse.

Edit: Actually, Elon doesn’t seem to do polls without wanting an outcome and his follow up “Careful what you wish for” would support Sacks.

sf_rob··on Twitter applies 7-day suspension to half a dozen journalists
The journalist were linking to an aggregator* of public FAA data of a jet that Elon may or may not be on… not “his location”

*granted he had to do a tiny bit of work to counter the insufficient obfuscation the FAA allows for privacy.

sf_rob··on Twitter applies 7-day suspension to half a dozen journalists
- No sudden bans for actions occurred in the timeframe of a TOS that was explicitly interpreted as allowing them.

Elon changed the TOS to obfuscate from it being a personal and vengeful decision.

sf_rob··on Beyond Meat is struggling, and the plant-based meat industry worries
I'm a vegetarian but I very much agree and I'm surprised to see the dislike of these product on this thread from both camps.

I want the full fat, greasy, meaty nostalgia of my very American-diet childhood and Impossible/Beyond have finally gotten 95% to achieving that. I definitely do not want some bean/vegetable patty with low fat, low salt, and weird texture.

Additionally, my Midwestern-diet wife happily eat Impossible (not Beyond) burgers with me which is a pleasant surprise.

sf_rob··on AngelList Talent is now Wellfound.com
Agree that the current situation was not ideal, but it was habituated at this point and now they're replacing one non-ideal solution with another one (in my opinion).

If they want to differentiate products, how about rebranding as TalentList or something like that to keep the association and buying talentlist.com and/or talentlist.co (neither of which is being used; both of which are registered). Let angel.co be a redirect; keep AngelList branding.

Agree that angel.co is confusing. I would have rather seen them use angellist.com as a lander to direct clients to talent.angellist.com and venture.angellist.com, but 1) it's too late for that now, 2) that doesn't differentiate brand which I accept as a goal.

sf_rob··on AngelList Talent is now Wellfound.com
I never understand why a brand with great name recognition and branding does this kind of thing.

Also, I'm really getting to the point where all scrolling low information eye-candy landing pages should have a giant <Take me to a simple landing page> button.

sf_rob··on General Mills, Audi pause Twitter ads, will evaluate site
More than that, how elastic is the demand for ads on Twitter? Were these companies barely outbidding for the slots? If there is a drop in CPM, will it bounce back from reallocated ad spend from other platforms? Hell, I've build dashboards to compare cost per conversion for different platforms for exactly this purpose.
sf_rob··on DontBuyDell.com
Granted my experience is filtered through my IT department, but my experience with Dell's enterprise warranty was anything but smooth. Replacing a faulty m2 and a motherboard were both multi-week affairs, so bad that I wrote our CTO about our machine requisition policies.
sf_rob··on What the $24.6B Kroger-Albertsons Merger Could Mean for Groceries
There's major overlap of sub-brands in some regions:

* Mountain states: King Sooper vs Albertson's

* PNW: QFC/Fred Meyer vs Safeway

* California: Ralph's vs Safeway

And that's only the regions I'm familiar with.

sf_rob··on What the $24.6B Kroger-Albertsons Merger Could Mean for Groceries
What I want to see is the the change in the percent of people who only have access to one brand umbrella of large grocery store crosstabbed against various distances (5,10,20 miles).

Will this take the number of people with a single brand of grocery stores within 10 miles from 10% to 20% or 5% to 7%? I really have no idea.

sf_rob··on Tesla Vision Update: Replacing Ultrasonic Sensors with Tesla Vision
My understanding is that Ford has done this for non-critical features as of late.
sf_rob··on Kill-sticky, a bookmarklet to remove sticky elements and restore scrolling
Is there a purpose built bookmarklet searchable repository anywhere like there are for extensions/addons?
sf_rob··on Ask HN: Have you bought I bonds yet? Why not?
The penalty point is an important one for the above. If you only plan on holding them for the minimum of 12 months and the second half interest rate is 3% then your effective annualized return is 5.48% (1.0962^.5*1.03^.25).

>I-bonds issued today yield essentially zero percent after inflation, and this will be true for as long as you hold them.

Yes and no, I-bonds use a trailing inflation definition so you receive a real advantaged proportionally to the difference in current and past inflation rates; this is of course speculative.

sf_rob··on HP LaserJet Tank – Refillable laser printer
I love my Brother, but their Mac support is (was?) laughable. Their main support path is to download the Brother app to load a PDF you output to your filesystem and send it to your printer. I'm clueless about the subtleties of printer drivers on Mac's but their solution was so clunky. Works flawlessly on Windows and with some minor tweaks on Linux Mint.
sf_rob··on .NET 6 is now in Ubuntu 22.04
Might this gain them marginal .NET developers? Maybe they have reason to believe that this will accelerate growth.
sf_rob··on Tell HN: Unpaid home assignments are not ok
I think that’s fair psychologically, but as long as I’m on a level playing field I’d rather have a reasonable upper bound or I’m going to feel forced to overly polish to stand out.
sf_rob··on Tell HN: Unpaid home assignments are not ok
I'd be okay with "homework" if either 1) it's truly time bounded via programmatic cutoffs or 2) it's paid.

For time bounding, I love the time estimates they give you for a decent sized problem. A major company told me that a feature extraction problem + report should only take 4 hours. They provided me with some large CSVs representing DB tables (which contained some malformed data) and wanted a brief report back.

That's unrealistic in 4 hours even for a great performer. Then you spend the weekend on it and they won't give you feedback on it because of the suits in legal.

It's disrespectful.

sf_rob··on U.S. annual inflation rate drops to 8.5%
IMO, you should be watching the month over month numbers and only using YoY to contextualize. Looking at the delta of YoY data doesn't tell you much without knowing the rate for the monthly report that was dropped and the monthly report that was gained.
sf_rob··on Musk SEC Filing
The comment you're responding to is referring to a meme about the optimal level of drunkenness for programming[1] not Ballmer's press performance.

sf_rob··on Tesla to Cut 10% of Jobs
That's an IBM-ism that has a lot of mind-share but is far from the standard operating procedure of most tech cos.
sf_rob··on The Bitcoin Investment Thesis Is Broken
I think ultimately the arguments against Bitcoin here revolve around it (still) being a speculative asset. I believe that speculative assets would inherently have the following properties:

* Are high beta (outsized correlation with general market moves)

* Are not (primarily) counter inflationary due inflation being a much smaller and uncorrelated to negatively correlated with speculation

* Are not (primarily) priced by scarcity since sentiment will effect price more than predictably slowing supply

* Are not (primarily) priced by usage since speculation is a greater use case for the time being

It remains to be seen whether Bitcoin will move into a more mature category. I have a small position (~1%, selling along the way) in Bitcoin under the digital gold argument/for fun, but I expect it to remain more volatile than gold for the foreseeable future.

sf_rob··on Pet Airways
I think it's just not overriding a Wordpress template default, but it's hilarious that their main homepage link goes to a wedding rsvp url* lol.

sf_rob··on Peloton replaces CEO and lays off 2,800 people
I personally agree, but from their view is the competition/substitution another highly scalable virtual fitness subscription or is it a trendy cycling class (Soul Cycle, Orange Theory, etc)? If it's more the latter, then $40 could be compelling value. Yes, the classes aren't the same, but they're convenient and cheaper.
sf_rob··on The McNamara fallacy: Measurement is not understanding
This isn't a great article IMO (I say as someone who is a big fan of qualitative user research, mixed methods, etc).

Per the first example, many types of attitudinal data can be quantified and conflating attitudinal data with qualitative data is itself a fallacy. It's possible that there were quantitative attitudinal signals that could have been captured or created as inputs to a more accurate model.

Per the second example, this is more a question of data validity than the metric itself. If the metric could be validated through better design and gamification prevented then it would likely still be a helpful indicator. Granted this is a very hard problem.

sf_rob··on Firefox about:config Menu Shortcut
I really like this route. Thanks!
sf_rob··on Firefox about:config Menu Shortcut
This shows also shows preferences modified in indirect ways such as about:preferences, devtools, etc. Helpful to filter a list of potentially manually toggled prefs, but not a 1:1 filter.
sf_rob··on Firefox about:config Menu Shortcut
I think the about:config utility I want is something that keeps track of manually altered preferences. Ideally something like userChrome.css where I can simply override/extend behavior. This is probably already a thing, but it's a bit annoying to not know the origin of non-default prefs.
sf_rob··on BusKill – A USB kill cord for laptops
It would be nice if it were a USB-C power brick + magsafe like attachment. That could also be a lot more discrete by shifting the hardware to the brick itself. Granted that limits you to fewer laptops.
