presto8··on Vivaldi Mail 1.0: Email client built into the browser
I used to have some hangs as well, but then I played around with the compaction settings and that seemed to fix it. I think there is a settings option to add a prompt before compaction, and maybe modify the schedule. It would be a good feature if they would allow compaction to run in the middle of the night to avoid bothering the user.
presto8··on Vivaldi Mail 1.0: Email client built into the browser
> Believe you me, I tried them all.

I'm curious, what issues did you encounter with Thunderbird?

I have found Thunderbird pretty wonderful overall. Using my Gmail as an example, I can select the "All Mail" folder (about 50,000 messages) and press Ctrl+Shift+K (for search) and it shows me results in just a few seconds.

I use Thunderbird to manage multiple email accounts, and it has been a huge time saver having it all unified in one place.

presto8··on How This Ends
>> there is a risk free alternative to stocks

> How is holding a bond risk free? It is a promise to give you a certain amount of money at a certain time in the future.

I Bonds. They are guaranteed not to lose purchasing power and not to have a negative return. Unless the U.S. government defaults on its debt obligations. That is as close to risk free as one is going to get :-)

presto8··on Ask HN: Whatever happened to Wolfram Alpha?
For certain types of queries, Wolfram Alpha gives wonderful answers that are superior to almost every other general purpose search engine:

distance to the moon

https://www.wolframalpha.com/input/?i=distance+to+the+moon

W.A. shows the actual current distance to the moon (as of right now, 224,520 miles). Google shows this as 238,900 miles, presumably an average value, but it has no explanation at all of what the number is. W.A. also includes a graph showing the variance. And a lot of other info.

presto8··on Bash functions are better than I thought
Here is a script that shows exporting results from a subprocess to a parent shell using a temporary file:

      if [[ $* == *foo* ]]; then
          echo "found_foo=1" >>$IPC
      fi
  }

  IPC=$(mktemp)
  find . -maxdepth 1 -type f | while read line; do
      # note: this is run a subprocess
      process_line "$line"
  done

  source "$IPC"
  echo "found_foo=$found_foo"

presto8··on When tipping was considered un-American (2015)
It would make sense if the tip were reduced when the minimum wage goes up, but it doesn't work that way, in at least two states I am familiar with (Washington and Oregon). Both of those states have minimum hourly cash wages for wait staff significantly above most states, yet the customary tipped amount is still ~20%.

presto8··on Ask HN: I have $450K cash, what should I do to maximize my return?
Thanks and yes, that is a good point. However, given that SPY is already at or near an all-time high, it seems unlikely that it would continue to go up every month or two by the premium amount (which itself is pretty substantial due to high volatility currently).

However, one adjustment if you have a bullish outlook is to reduce the delta from 30 to 20 or 10. Premium would go up and assignment is more likely.

OP, do it and report back :-) Even if you don't have any options experience, I am sure any broker will be happy to give you level 4 options (or at least level 2 which is what you need for cash secured puts) if you deposit $450k capital!

presto8··on Ask HN: I have $450K cash, what should I do to maximize my return?
If you decide to invest it (in an index fund, for example SPY or IWM), I am not seeing any downside to selling cash secured puts. For example, on SPY, you could sell a short 48-dte 30-delta put (strike $312 on Sept 18) for $616 premium. If it is assigned (SPY goes below $312 on Sept 18), you will get 100 shares of SPY for $31,200 but you are no worse off than if you had bought today and also you will have reduced your cost basis to $30,584. If SPY goes up, the shares will not be assigned; pocket the $616 premium and repeat the cycle. Repeat this loop until your entire $450k is invested. This also has the advantage of spreading out your purchases, and thus dollar cost averaging them. Just a thought... I welcome any criticism of this approach :-)
presto8··on CDC Now Recommends “Use of Cloth Face Coverings” (DIY Masks)
Table 6 for the N95 mask row cites w45 and w47. w47 had only 13 people in the study. And both w45 and w47 cite a medium risk of bias noting lack of description of controls and inconsistencies.

It would be nice to have more rigorous studies to support the claim?

Just to be clear, I do think people should wear masks!

presto8··on More emphasis on trains in Europe to replace flights
The most well-executed high-speed train system I can think of is in Japan, e.g. shinkansen from Kyoto to Tokyo, which Google Maps is reporting as 2h11m. Distance by road for that city pair is showing as 464 km, for an average speed of 212 km/h. So I think around 200 km/h can be considered the highest possible currently practical average speed of a high speed train network over a reasonable distance.

I tried to find something equivalent in Europe to compare, maybe Frankfurt to Berlin? Google Maps is showing that as 4h16 by ICE over 549 km, for an average speed of 128 km/h.

Maybe the inefficiencies can be eliminated and the European trains can get closer to 200 km/h average speed?

There may be a downside, if the cost of compliance is too high and the business decides to stop offering the product.

presto8··on France to tax flights from its airports, airline shares fall
That international/domestic surcharge looks like an airline imposed charge. Not sure why they do it that way instead of having it in the ticket price. But the actual taxes paid on this ticket are a lot less when that surcharge isn’t included.
presto8··on Boeing altered key switches in 737 MAX cockpit limiting ability to shut off MCAS
Are you referring to AF447? According to the BEA incident report, the AF447 plane was already equipped with heating systems for the pitot probes and AoA sensors.

"1.6.9.1 Probe heating The probes that are installed on the aircraft are heated electrically to remove water by vaporisation when the aeroplane is on the ground and to protect them from icing in flight."

presto8··on Show HN: Baxx – Unix-friendly backup service
Love the idea and implementation! However I have two main questions/concerns that might prevent me from being a customer:

Cost. Currently I pay $10/month to CrashPlan to store 2TB a month. I think your plan is to simply pass through the glacier price, but even that would be much higher cost I think?

Large files. Because I only have finite monthly bandwidth and a limited upload speed, it would be good to do incremental backup of large binaries, only changing the parts that changed.

presto8··on Mastercard will stop free trials from automatically billing once they're over
I tried this feature from my bank (not BofA) several years back. It didn't work as I expected. Even after revoking the card, the merchant was still able to charge me and the amount was just posted to my "real" card number.

I called and complained and the customer service told me that once I had authorized the merchant to charge me, they would accept any future charges even if the card number was closed.

Just curious, have you actually used BofA's service? Maybe the implementation is different now...

If it works, it would be a great way to limit those automatic renewal situations.

presto8··on On Hold for 45 Minutes? It Might Be Your Secret Customer Score
Yes, you're right on Alaska, although since they don't fly internationally, it's much harder to rack up the miles with 2 trips (as parent was suggesting). Incidentally, Alaska is my favorite carrier for many reasons, but only for domestic flights.

As for spending with the credit card, unfortunately that isn't an option for me since my company pays for many of my tickets. And they will purchase the cheapest ticket, which often means buying it on the partner airline (e.g. Lufthansa plane but cheaper if booked as an Air Canada).

Thanks for the tip on Aegean. I checked it out and looks like 24,000 miles on partner airlines without any other restrictions to get Star Alliance Silver! Looks like a winner!

Status programs are really in a sad state on airlines. They are supposed to be a reward to customers but many times end up feeling punitive. For the airlines like United that have the minimum dollars spent requirement, I wish they would just make that the sole criterion, which would at least simply things!

presto8··on On Hold for 45 Minutes? It Might Be Your Secret Customer Score
Two RT trips to Asia might barely meet the minimum tier for miles, but most (all?) airlines now have a minimum in dollars spent, as well. For example, for the first status level, United requires 25,000 miles and $3000 spent with United (this means code-share partner airline flights don't count).

One year, I flew RT SFO-Singapore (16,000 miles RT) and SFO-Tel-Aviv (10,200 miles RT). Due to getting a really good deal on economy tickets, those two tickets were less than $3,000 total and thus I didn't get even the most basic status level.

presto8··on Hottest Rain on Record: Rain Falls at 119°F in Imperial, California
> I can not tell if it is 30 or 31 °C outside.

Most thermostats I've seen allow changes of 0.5 degrees C. So it seems that the thermostat manufacturers feel that the majority of users can tell a difference.

And sometimes 1 degree C delta is too much for me in a room (e.g. 21.0 is comfortable, 22.0 is not, 21.5 is just right). So it's obviously a personal preference, but at least for me, I can tell a difference between 0.5 degrees C.

And thus for my use case, whole integers in F is a slightly superior user experience since it avoid fractions.

presto8··on I amplified my home's Wi-Fi with aluminum foil
This blog is missing a lot of details before we can consider this experiment successful. Most importantly, what is the usable throughput of a station in the "improved" coverage area? I would recommend using iperf before/after to see if there is any practical benefit.
presto8··on The Emacs Calculator (2009)
I'm the exact opposite. RPN calculators are totally natural to me, whereas I get confused on normal calculators.

Normal (non-algebraic) calculators are inconsistent. To get "2+3", it's infix: 2, +, 3, =. To get "cos(45)" it's postfix: 45 cos (and no equals). And something like "cos(2+3)" is a mixture of both. RPN, is always the same, numbers first, then operators, and usually more keystroke efficient. Some operators take multiple arguments.

RPN also has the advantage of (rarely) needing a memory register, since the values can be left on the stack and accessed as they are needed.

Some operating systems use a "fake" MAC address when not associated and scanning for networks. In theory, this would prevent tracking when a user is not connected to the SSID.
presto8··on Ask HN: We didn't get a single person to pay for our SAAS – what could be wrong?
I don't know anything about your business, but just some quick comments: I went to the site, easily saw the "Get started" button. Clicked on it, there is a landing page that doesn't add any value in my opinion - why is it there? Clicking "start" takes me to a "fill in info" page, I don't know how much this is going to cost me nor what I'm signing up for.

I think clicking on the "get started" should go to a page that tells me how much it's going to be (preferrably 30-day free trial) and the obligation terms ("cancel anytime"?) and then just ask for the email to get started. I saw some other people made similar comment about just collecting the email elsewhere.

Good luck!

Private education is not generally tax-deductible in the US (e.g., private high school). 529 funds can be used for post-secondary education, but even then it's only the gains on the account that are exempt from tax if used for education.
