wittjeff··on Ask HN: First-time dad-to-be. What do you wish you'd known back then?
Anxiety, anger, and pain share some circuitry in the brain. If you're feeling like you're going to have a short-fuse (easily angered) day with your kid, pop one ibuprofen. I found it helped replenish the zen/chill reserves immensely when I really needed it. But watch your total consumption of all pain killers; they do cumulative damage to your liver.

Accessibility is a strong gating factor for some (including me). I don't see it in the docs. The whole thing seems to be missing any ARIA (see https://www.w3.org/TR/wai-aria-practices/examples/grid/dataG...) Let me know if you want help.

Morning vs Evening Light Treatment of Patients With Winter Depression

"These results should help establish the importance of circadian (morning or evening) time of light exposure in the treatment of winter depression. We recommend that bright-light exposure be scheduled immediately on awakening in the treatment of most patients with seasonal affective disorder."

The $10K limit is for I-bonds. If you want more inflation protection from the treasury, you can buy TIPS up to $5M.

I can, but it isn't 100% control. It's like putting a (voluntary) damper on an (involuntary) pendulum.

Lots of blind and low-vision people would appreciate such an option.
wittjeff··on Ask HN: How to communicate voting button state for screenreaders?
Add aria-presses attribute to show the like/don't like state as aria-pressed="true" or aria-pressed="false". You could also add aria-live="polite" to make the label be announced again when it is updated.

wittjeff··on The Covid Zoom Boom Is Reshaping Sign Language
Check out Cued Speech (one-handed phonetic signing). https://www.youtube.com/watch?v=jn4e9V3oigs It's a different modality of the local spoken language, not a separate language like ASL. You can learn it in a weekend. IMO it should be taught to everyone in the 2nd grade to help with phonological awareness, which is helpful for visual literacy. But it'd also be useful in a lot of noisy situations throughout life.
wittjeff··on Artist releases album called “Ok Google Play Music” on Spotify
Regressions in language understanding are common when children are acquiring deeper understanding of the rules of that language. For example a kid may start saying 'letted' for the past-tense of 'let', even if they had used it correctly before.

wittjeff··on Unshaky – Tries to address double key press issue on Apple's butterfly keyboard
I am really surprised to find that Apple does not include a Bounce Keys implementation (which is what this is) as an accessibility feature in MacOS as Windows has since forever. My guess is that this is due to the fact that many users find the difference between Bounce Keys, Repeat Keys, and Slow Keys confusing.

wittjeff··on Georgia Tech Creates Cybersecurity Master’s Degree Online for Less Than $10k
GA Tech does admit some students to the Masters programs who don't have bachelor degrees. The Micro Masters programs at edX may be a way in to the MSCS programs without the undergrad step. One benefit of the MM programs is that they're basically open access. You do what is essentially 1/4 of the degree online first, and if you do well you may be admitted to either the residential Masters program or the online program. Disclosure: I work at edX.
wittjeff··on California law requires businesses to let you cancel your subscription online
In some states only one party needs to know about the recording. In some state all parties need to know about it. If you tell them up front, they can refuse, but then it's just evidence that they're being difficult.

Certain keywords like "lawsuit" can break the strictly regimented conversation tree too.

wittjeff··on California law requires businesses to let you cancel your subscription online
I've only used this a couple of times but I think it works: "I'd like to cancel my service. I'm going to say this really clearly for the recording, in case I have to subpoena this for evidence. I want to cancel my service, effective [date]. When I hang up this phone, I want there to be no financial relationship between myself and your company of any kind. None. I don't want any further communication from you other than a final statement showing a zero balance due. Now we can make this call as long as you'd like. No. Financial. Relationship. We're done." Then go silent, and if they try to pitch you any products of any kind, interrupt and ask "Are you refusing to cancel my service? Speak clearly for the recording."
wittjeff··on A week-long programming retreat
Post may have been by Tynan (http://tynan.com); he's big on working while on transatlantic cruises. Following his advice, I have done the same thing several times.

Here are some tips: - Find the best cruises most easily on cruisesheet.com (disclosure: it's Tynan's project)

- Royal Caribbean has the best internet at sea through O3b. In the Caribbean or Mediterranean it's about 70ms latency. In the middle of the Atlantic it's about 220ms latency. So Skype may work but the delays are annoying. Plenty of bandwidth now though. You may have only "one 9" service on average though. So scheduled conference calls are always a gamble.

- Repositioning cruises (many ships move from the Mediterranean to the Caribbean and back seasonally) in April/May and October/November are the cheapest cruises you'll ever find. 5-8 days at sea means plenty of time to get some work done, as well as goof off a bit during the evenings. For the second week (Europe or Caribbean), I find it easy enough to get an hour or two of email catch-up in on port days after getting back from a shore excursion, but it's easier to just say port day = vacation, sea day = work and great food.

A 2-week repositioning cruise may cost as little as $600 per person including taxes and fees. Add another $200pp for gratuities, a few $hundred for shore excursions, and a few $hundred for airfare to get back home. Depending on where you go, you may get the benefits of a 2-week vacation for the price of one on land.

Similarly, if you want to do a one-week offsite with your startup (particularly if you're all remote most of the time anyway), this is probably cheaper than flying your crew to any big city.

The seminars-at-sea model was also well proven out by geekcruises.com, now renamed insightcruises.com

My wife and I have been renting an off-season beach house near Boston for 8 months out of the year for less than the price of a basement studio in Cambridge, then traveling during the summer. This means our repositioning cruises are further discounted by the fact that we aren't paying rent or mortgage on an empty house. It's hard to beat if you both have good schedule flexibility.

wittjeff··on Ask HN: Idea Sunday
I think the main weakness in this business model, which is the same one with condos, is that people don't like to think about the really expensive things that they don't need to pay for regularly. When you need a new furnace/roof/fence/siding/driveway/etc., it's a multiple-$K hit. If you haven't budgeted for it (and I think most people don't), then the tendency will be to put it off for another year or three. I would guess the regular maintenance you outline takes care of perhaps only half the larger long-term upkeep problem. So prompt comprehensive maintenance with a flat monthly rate requires what seem like very high rates and some escrow, and also involves lower margins than it may appear to the customer. You may also become a magnet for customers who have already accrued a lot of "maintenance debt". So maybe you'd just need a long list of major unpredictable maintenance exclusions? Would that still be a satisfactory value proposition?
