This exact thing happened to me with Greenpeace. Didn’t realize I had a subscription until later, then the awkward call to cancel and associated guilt trip.
Imagine an electric vehicle that reenergizes in five minutes, just like gas
Two former U.S. Army Green Berets have developed a new and innovative solution to address the myriad of problems associated with Electric Vehicles including single cell failure, slow reenergizing, defects, and cost - oh and along the way it just might democratize energy for the developing world and beyond. Imagine an electric vehicle that costs thousands of dollars less than those currently available and reenergizes in five minutes, just like filling a tank of gas.

I was just asking down thread what cases exist to block prepaid cards if sufficient funds are available. Seems like I've found my answer; for you then it seems like this removes a lot of the customer retention/customer engagement cruft?
Lol, Mirco-service architecture is a vehicle that can make it easier to achieve those goals. It is not a black or white solution. There are pros and cons.
Third street LRV doesn't really improve the situation. It was added in anticipation of and simultaneous to the redevelopment of the Mission Bay area. I don't live in that part of the city, but as far as I know folks living in the southeast took the express buses downtown as it jumps on the freeway for most of the way; they probably mostly still do because the LRV is ridiculously slow. I can walk from downtown to AT&T Park almost as fast as the LRV can get there, and the LRV is either underground or has the right-of-way most of the way there. I haven't taken it past Mission Bay into, say, Bayview, but it's still slow getting anywhere in Mission Bay as it loses right-of-way.

The central subway LRV is mostly for tourists, and while the third street and central subway lines were, together, partly intended to help shuttle people from the SE to Chinatown, as of now the Chinese community still oppose it. Everybody knows why they oppose (it just can't be said aloud[1]), but personal convenience usually trumps anti-social community sentiments. Once it opens I guess we'll see. If opposition quickly goes away then that would suggest it's more convenient than the existing heavily trafficked express buses, but somehow I doubt that will happen.

What would be a meaningful addition to the network is if they finally extended the E-Embarcadero (sister to the F line that opened in 2016) to the Marina, using the Fort Mason tunnel. But crime in Fisherman's Wharf is way up, so I suspect it's being quietly stalled by Marina activists.

In any event, LRVs suck, the F- and E-lines notwithstanding. They're slower than buses and 10x as expensive, in SF and most every other American city.[2] Oppose LRVs! All they do is give public transit a bad name. It's right-of-way or no way, but preferably grade separated.

[1] It's the same reason the North Beach and Fisherman's Wharf communities successfully stopped its extension past Chinatown.

[2] I think the only LRV I've been on outside the U.S. is Vienna, but it was mostly historic. Somehow it seems historic routes see less competing traffic, perhaps because they were built in a time and place that doesn't permit much car traffic to begin with. I've been on BRTs in Guadalajara and Quito--if you can't grade separate but can acquire a right-of-way, LRVs seem like a waste of money. They're even a worse waste of money if they don't get unimpeded right-of-way.
I've contributed to OSM, fixing trail maps based on traces I recorded with my Garmin GPSMAP 64 which is configured to use WGS-84. If OSM wants something else they'd better let their contributors know how to deal with this.
My favorite ecommerce glitch was a guitar center coupon for $50 off being usable an unlimited number of times. I didn't push my luck and only applied it a few times. Surprisingly they honored it and I got a bunch of miscellaneous guitar accessories for free.

IDK about what level of "public services" are needed, but rural or rural-ish locations often have broadband connectivity, and are arguable easier to earn a living wage due to the low cost of living.

I lived in Provo (college town, 50 miles south of Salt Lake City) a few years ago. Had Google Fiber, lots of jobs, and houses for <$200k.

People want to live next to other people.

A gym I joined years ago required a certified letter sent to their headquarters.

I think it's a public service to tell young people how gyms work. Basically it's high pressure sales ("this discount membership offer only good for today!") plus hard to cancel memberships.

Gyms work on a model of human nature + oversubscription.

Human nature means that a huge % of people join the gym, go two weeks, and never return. Then it's hard to cancel, so the same people that don't bother coming in, don't bother figuring out the membership cancellation gauntlet.
Didn't expect a congressman to be so technical
If they won't refund you then they're being dicks. Chargeback your credit card if you're in the US. You'll almost certainly win and there's likely no penalty if you don't.

Chargebacks also cost providers money on top of the refund, which disincentives their shitty refund policy.

I run a SaaS company (with a great refund policy) and am part of many SaaS startup groups and it's standard practice to basically refund anyone who asks.

The refund costs way less than the damage to your brand / negative reviews.
While the project seems to have neat goals the:

"unlimited 4G / LTE wifi data and a mobile hotspot from Sprint", is meh for $500.

Consider this: Buy a unlocked Fi moto X4 from best buy for like $200, do the Sprint BYOD deal with a Google Voice number ($3 to unlock number for porting), this will give you $4/mo 'unlimited' service for a year. Slickdeals has a long in-depth thread on the full details of this arrangement.
FYI, HBO does exist in Canada but Bell Media holds all the rights to it so they’ve made it available on their own streaming platform called “Crave”.

It does exist. For a long time under hbo Canada now under the crave brand.
We have no idea if it was even undefined in the first place, since the PPU documentation is not public.

You are correct thought, often guarantees about behavior can be made after the fact. Generally what happens these days is someone determines they need or want to use a certain undefined behavior. The hardware people then go, look at the RTL for the chip and confirm it behaves in a certain way, and then they UPDATE the documentation to explicitly document the newly guaranteed behavior.

Conversely, often something that is documented to work just doesn't. Especially in the case of console developers who tend to be using early steppings of custom silicon. In that case sometimes when you go to the HW team they fix it in the next stepping, sometimes they document it as errata and move on.
I could be starting a food war here but I dare declare that California has the best cuisines in the world because

1.) for many of the ethnicities, california usually has the largest immigrant communities, outside of the native country. Therefore the dishes can be much more authentic and cater to the native crowds. As opposed to a Greek restaurant in Tokyo, or a
Thai restaurant in Paris. When I lived in Japan I often missed my Vietnamese pho. And when i lives in Paris I often craved for my Mexican burrito.

2.) it doesn’t have any food history, and therefore no codified rules on how and what cuisines should be ( as opposed to French cuisine, like mentioned in the article ). Therefore we have Californian sushi, Korean tacos, Japanese pastas, Korean hot dogs, and so on. Fusion and innovation is alive and well

3.) fifth largest economy in the world that helps to support diverse and vibrant restaurants, farms and foodies

4.) real focus on vegan cuisines. If you were a vegan you would be blessed to live in la or sf. You would be able to not just be able to get vegan but also Vietnamese vegan, Thai vegan, American vegan or Japanese vegan cuisines. If you tried backpacking through Asia or Europe as a vegan you would know how hard that is.

Michelin guide recently released a California guide and California is now on the map as a foodie destination. Even though it only has 90 Michelin restaurants as opposed to Japan’s 230, I have way more fun dining in la or sf than Tokyo due to the diverse ness and casualness of the cuisines. (But Tokyo will always have a place in my heart on how perfectly executed a single ingredient/dish could be)

> nation's (or the world's) wealth be assigned to the democratic process

It's not the nation's wealth. It's Bezos' and Musk's wealth. You and I didn't earn it.

Exchanging money is democratic. When I perform a service for someone else, they give me their votes in the form of dollars and then I can then give those votes in the form of dollars to someone else. Collectively we do this every single day.

Like the Bicameral Legislative, we have one democratic system with equal representation (the Senate) and another democratic system with proportional representation (the House). Likewise, individual citizens like states enjoy equal representation (one vote) and proportional representation (wealth) where the proportion of representation you get is dependent on how much cash others in society have voluntarily given you in exchange for something they find valuable.
I feel like this is blindly upvoted. The video is underwhelming, and doesn't come close to answering the question.

That said, I'm very impressed by the congressman in the video, as it sounds like he knows what he's talking about. Wikipedia doesn't mention much about programming in his bio...

You're correct about JavaScript. I forgot about the backticks.

Thank you for the explanation of the f-strings. I'm pretty sure that migrating old strings to "\{x\}" could be automated but we can't force everybody to migrate their code. There is probably no other way than the one they followed.
Yeah. Glonass (the Russian system) had an 11-hour outage back in 2014 because they uploaded an incorrect ephemeris to all their satellites and could only correct them when they flew over Russia. I think that was the worst GNSS outage of the modern era until this one.

What cities are these? Most of the large southern cities I'm aware have terrible traffic. Atlanta, Houston, Dallas, Austin, Tampa, Nashville--they all score terribly for traffic.

The only reason they don't rank at the very top is because they are in fairly low population density areas.

From the linked Wikipedia page.

Restrictions on validity

According to Downs, the link between average speeds on public transport and private transport applies only "to regions in which the vast majority of peak-hour commuting is done on rapid transit systems with separate rights of way. Central London is an example, since in 2001 around 85 percent of all morning peak-period commuters into that area used public transit (including 77 percent on separate rights of way) and only 11 percent used private cars. When peak-hour travel equilibrium has been reached between the subway system and the major commuting roads, then the travel time required for any given trip is roughly equal on both modes."[citation needed]

So in general, it's entirely unclear whether this effect applies in most scenarios on the road network. In my area of NYC, a poster child for arguments about this effect and why we should never build anything due to "induced demand", it is vastly faster to drive across any borough other than Manhattan rather than taking public transit at all times except certain corridors at the absolute peak of rush hour.
No, I'm not. I actually read the article and exercised the principle of charity.
>Anything we might do in space or to try to live on Mars is much-much (much) more difficult than fixing what problems we have on Earth to keep it healthy and habitable.

This sounds true upon first glance, but is it really? Scientifically/technologically speaking you're certainly correct, but fixing Earth is also a political problem.

I have much more faith in humanity's ability to create technology that saves Earth then I do to humanity's ability to put aside vested and/or selfish interests and work together for a common goal. The former is hopefully a matter of several (or more) generations, while the latter I imagine will never be "fixed."
> We could have pagination.

Pagination is a bug, not a feature. Screens are not books.

The only, I repeat ONLY, reason to use pagination on a web page (That isn't incredibly long, such as a table with hundreds of rows) is so you can serve more ads.
The article explicitly warns of that sort of confirmation bias.

In particular, it points out that the free market had already failed the people in the community. The remedy, essentially government financial incentives to business, was the only thing that made enterprise possible. But since the whole system innately runs at a loss for the comunity, a harsh future reckoning arises.

So it points to a possible deep flaw in our economic system and underling assumptions that simple theories obviously do not explain.

After all, one should believe the simplest working explanation, but certainly no simpler. The complete confidence in completely unfettered markets is apparently overly simplistic. Likewise, some forms of business incentives are counter productive.

Amazon would be within their rights to refuse to honor such purchases. I also don't think it's ethical to take advantage of such mistakes. What if it was you who accidentally listed your house for $60,000 rather than $600,000? What if you accidentally included an extra 0 on the check you wrote?
>>Though 800mm is kinda ridiculous and probably impossible to hand hold

If you have a bit of DIY spirit - You can get a decent 4" Newtonian telescope, porro prism and an intermediate lens and adapter to play around with and see if you like it for much cheaper - roughly $1200

Bonus: For $45 you can get a solar filter and take snazzy photos of partial eclipses.
That's really interesting. We haven't seriously considered what it would take to be able to live guilt free without changing lifestyle dramatically. It certainly means doing way more than offsetting, but there is a (perhaps distant) future where people can have an amazing standard of living while still helping our planet thrive.

For instance—if you were to get your community on 100% renewable energy, help politicians who care get elected, fund clean manufacturing/construction companies, and maybe do a handful of other things maybe you could live guilt free. We will have to think about this more, I'm glad you phrased it like this.

One solution would be to borrow from Perl. You make a do block that executes once unless continued, and allow conditions on break and continue:

do:
thing()
thing()
continue if condition

And you can now express "skip ahead" with a `break if X` as well.

> Western social media companies are increasingly censorial, following Chinese censorship in spirit not structure.

The structure is what matters. Kings and despots throughout history have frequently ruled fairly and justly. Out of all the decisions they made in that role, they probably made many more fair ones than unjust ones. But their making the right call in any particular case is not a reason they should have had that much power in the first place.

Western social media is stepping up moderation of harassment and calls for violence, but they're making an effort to do so in an accountable and transparent way while doing so. And I don't think even they are accountable enough; I hope that Instagram and WhatsApp really do get split off from Facebook.

> The firewall and grey legislation around vpns is calibrated that low information audience gravitates towards party line while those seeking information has access.

Am I understanding correctly that your position is that this is a good thing, or at least fine? Because this placates the masses which tend more towards violence or other destabilizing actions, while allowing elites to continue to have a robust debate? Is that an accurate characterization of your position?

> The numbers suggests more Chinese people are aware of western and Chinese perspectives than vice versa. Leading me to ask, in general, who is actually more informed?

I'm not worried about American awareness of Chinese perspectives. I'm worried about Americans' missing or inaccurate understanding of American history, e.g. the Lost Cause.

I'm not worried about Chinese awareness of American perspectives. I'm worried about Chinese suppressed or sanitized understanding of Chinese modern history, e.g. June 4th.

I don't give a fuck about Chinese people being able to read Americans' sanctimonious takes on Tiananmen. I want Chinese people to be able to read Liu Xiaobo's take on June 4th, on Charter 08, on 996.
I recognize this scheme because it's already implemented in Switzerland. Trains are not high-speed but rail links have been optimized to multiples of 30 minutes. At hubs, trains arrive just before minute 0 or 30 and leave after the clock has ticked over. At major centres, trains depart on a 30 minute cycle in all directions.

Arriving at a hub you know you'll catch your connection to the next hub without even consulting a schedule. Feeder trains are also synced up so you get little layover in general. If you're sitting at a hub station, it's easy to tell time by the ebb and flow of passengers.

Now what they should do is just run everything 50 percent faster at high speed to get the cycles down to 20 minutes. Have everybody walk 50% faster at hubs too. What could go wrong?
R's data.table package is much faster and much nicer to use than pandas.

IANAL. Any U.S.-based lawyers out here?

I believe a listed price is an "invitation to treat" which means a retailer can charge whatever they like regardless of listed price (whether in a physical or online store), but at what point can't an online retailer cancel/back-out of a transaction? Let's say the merchant and buyer are both California-based for simplicity. Would it be legally similar to "theft by discovery" (e.g., taking money falling out from an overturned armored truck) for accepting goods sold at an excessive, erroneous discount? Or would it require proving intent on part of the buyer that the price was a serious mistake they deliberately acted in bad-faith to exploit?

Let's say the (over-simplified) phases of a transaction are:

1. Agreed - Buyer clicks "Buy".

2. Paid - Payment is posted.

3. Shipped out - The product leaves the custody of the merchant.

4. Received - Customer receives the product.
The thing with GNSS is that it is WELL below the noise flow and you need a lot of coding gain to receive it. That on the other hand really reduced the data rate at this you can transmit secondary information such as ephemeris and slowly changing time information. Sending 3 bits for day of week instead of 16 bits or so for a full date makes a real difference for time to the first fix after a cold start.
Looks like he comes from an NSA background. Have to say, I'm very heartened to see someone in congress ask such detailed technical questions about cybersecurity issues.
Same. They’re grasp of the ecosystem and the involved bits of tech is exactly what more representatives needs to grasp.
Back in the 1998 there was one website that let you enter negative values into the quantities to zero out the cost of other items. I notified them quickly and they let my order though as a way of saying 'thanks'.
Yeah this is pretty interesting. There's some set of activities (getting everyone on renewables, making clean construction/ag/transportation cost effective, political action, etc) that would actually allow someone to be guilt free. It would be way more money than just offsetting the footprint but it could fully cover all externalities....

That's kind of theoretical still, but perhaps we could crack it
This completely contradicts the rest of Python grammar, and indeed many languages’ grammars. The consistent way would then be `while x < 10` but that too looks ridiculous. The issue is that you can’t have post-clause syntax in Python due to its infamous spacing-is-syntax idea.

Yes! I looked into some mirror lens options too trying to get the price down more. It turns out that doing a zoom/crop on the computer afterwards gives me the same or better results apparently. I haven't thought about a telescope though that would be sweet for pictures of nests.
Wow, and I thought I had it good with the HP fire sale years back.
Congressman: I was really surprised about the Rust language. So my first question is, why was the Rust language chosen as the implementation language for Libra? Do you believe it's mature enough to handle the security challenges that will affect these large cryptocurrency transactions?

Facebook: [We will own & control the code.]

Congressman: It looks like Libra was built on the nightly build of the Rust programming language. It's interesting because that's not how we did releases at the DoD. What features of Rust are only available in the nightly build that aren't in the official releases of Rust? Does Facebook see it as a concern that they are dependent on unofficially released features of the Rust language? Why the nightly releases? Do you see this as a function of the prototyping phase of this?

Facebook: [No answer]
