Unless Chase has a new procedure in place, you don't get a new card number issued and put in the mail to you until the old one is deactivated.

So there's one of two choices: contact millions of cardholders telling them their card is now dead 4 days before Christmas, or just clamp down on transactions (reducing the bank's liability) until they can get a handle on issuing new cards.

A dead card means less potential merchant fees coming in to Chase and/or people switching to other card issuers.

I agree that we in the IT profession often forget that we're being paid relatively well to work in a comfortable environment, doing something that's reasonably challenging/interesting. Most of us also have an outside interest in tech, so it's pretty close to having one's hobby as a job.

However I think focusing on physical exertion is misguided. A carpenter may be out doing physical work all day, but his/her job requires nothing like the mental exertion of a programming role. A long day of coding is just as exhausting as a day spent climbing ladders and lugging tools, if not more so. And as one gets older, both types of exertion take a greater toll and require more recovery time.
I think your parent misunderstood, thinking there was an implicit promise that you won't even be inconvenienced by fraud.
I think it depends upon the bank, because some are. My bank called yesterday to tell me they were preemptively hot-carding my wife's debit card because she used it at Target.

It's a small local bank, though, so it's not like Chase, who has to deal with potentially millions of customers.
> "I would recommend against having dealings with the obviously mentally ill. I'm not sure in what sense you might be legally liable (for a civil suit) if they happened to commit suicide a week later and mentioned you in the note. ... Leave the clearly crazy to the professionals."

Here's a bit of Hacker News "empathy" that I find fascinating. Likely in the same sense that you find the mentally ill fascinating.

The comment reads like some kind of bizzaro water-cooler advice on how to deal with that neighborhood "crazy caller" problem. Like when someone commiserates with Jane from accounting when she tells them she's worried because she can't keep the neighborhood kids out of the family pool.

On the surface, it's empathetic: "If this is your first... I can understand..." In fact, the comment does (correctly) assert that professionals are better inclined to help the mentally ill than the lay-person. But underneath, the comment reeks of an unseemly attitude that suggests the mentally ill are a burden to be cast aside at all costs (with the requisite sigh).

Perhaps it's a bit unfair of me to parse out those bits of your comment and infer so much. But, seriously?

Have we really reached the point where we are calculating the likelihood of "sav[ing] someone by argument" vs. the risk of civil liability?

Are these people merely objects of amusement and fascination?

I wish I were a better writer, so I could flesh out exactly why your comment bothers me. I think it has something to do with the clinically detached tone and the casual implication that the mentally ill are at best a passing amusement; and, at worst, a liability to be avoided.

Maybe I just need to take a break. I must be misunderstanding your comment.

It seems cool but I have a couple of concerns. Firstly, how exactly is it detecting when someone is nearby? The iPhone doesn't have NFC for example and GPS isn't exactly the most accurate thing in the world. Secondly, it seems as though the device somehow connects to a front panel with a direct shaft to move the lock mechanism, it seems as though it would be fairly easy to compromise with a bit of brute force. How solid is the front panel? The large size also gives a lot of leverage for breaking off.

The gas works well at preserving the coffee from oxidation. The bigger problem is with water temperature - espresso is incredibly sensitive and will become either sour or bitter if the temperature goes outside a very narrow band. This is what you are spending money on with expensive espresso machines - PID temperature controls and lots of heavy brass parts to maintain an even heat. Nespresso machines are pretty cheap and plastic and I believe they use specially made bland coffee blends to disguise this.

Frankly you are better off with French press or pourover at home.
I was hoping they might be getting robots to make t-shirts.
It's virtually impossible to be a great cook at home; commercial cooking equipment puts out a lot more heat than consumer equipment and it does make a difference. Take a simple roasted chicken: what comes out of your home oven will not be the same as what comes out of a commercial oven.

That said it's not difficult to prepare decent food at home; if you're unable to, maybe fundamentally it's just not something you care to do. Fine, nothing wrong with that, eat out or buy prepared food. If you don't like what's in the freezer, I find that the deli section of most supermarkets has a variety of prepared dishes that are ready to reheat and eat.

I've been there and done that, so please don't take this as a negative when I say this -- the only thing you need to learn is how to finish.

I don't know your motivations, but what always happened to me is that I'd get to a point in a project where the tools seemed constraining, and whatever problem I had, some other toolset aimed to solve it, so I'd jump ship, usually before making any sincere efforts at solving it with whatever language I started the project in.

Or even worse, I'd write the hard parts, and then be left with the boring bits. Login, registration, sending notification emails, etc., so I'd hop on over to Rails which let me rewrite all the fun parts, and then scaffold the rest, only to find now I had a new problem somewhere that I hadn't considered.

Finishing is mental, but once you get past the hump, it gets added to your skillset just like every other skill. Once you can ship, you play the game differently. Good luck!

Watching the video almost made me sad that his effort is going by unrecognised. Even more so because the OS appears to have documentation and plenty of tips built in, but nobody but him will ever use it, so it's all in vain.
> Well, they're clearly claiming that the "secret contract" as reported did not exist.

Crap. They're only denying a carefully-worded strawman. They leave open:

1.) Adding support for a known-flawed PRNG for free and then entering into a secret contract with the NSA to make the already-supported PRNG the default.

2.) Entering into a secret contract with someone else (FBI?) to "incorporate" a known-flawed PRNG.

3.) Entering into a secret contract with the NSA to use a PRNG that they didn't yet know to be flawed because they didn't look at it.

etc...

Edit: Pointed out first by https://news.ycombinator.com/item?id=6952801.

Edit: You're right, they did deny it 'as reported', with "Recent press coverage has asserted ...". This could involve a creative reading of "[r]ecent press coverage", or a lie.

> I fail to see the difference

The difference is that food, by and large, is not even an art. And I'm saying that as someone who cooks professionally and looks up to the greatest chefs of all time. If you are not developing new dishes or pushing the edge of your cuisine, what you're doing is not really an art. People have to stop perpetuating the myth that food is this black box that just happens. It only serves to make some chefs richer and dumbs down the rest of us.

> Nutrition is a solved problem. Just drink soylent.

You're trolling right? Nutrition is not a solved problem. That's like saying medicine or human biology is a solved problem. We still don't know a lot of things -- what we need, what we want, what we should avoid. And I'm sorry to break it to you but Soylent is not a solution. Might be in the future, but drink it full-time in its current state? Not exactly nutritious.

> But it's hard to reproduce food from recipe.

I realise that not everyone is a good cook. But to be honest, practice goes a long way. You might think those few hours of your time are wasted, but I really think otherwise. We spend orders of magnitude more time reading, IMing, working. Spend one whole weekend cooking. I guarantee you'll be a much better cook. And it's a skill that will last you forever. It's also tasty.

> - better frozen/packaged foods

What's wrong with fresh food? (Not living in the USA, but fresh food is plentiful where I live). Even then, what's wrong with your frozen chicken breast? Cook it well, and it will beat out the offerings of most average restaurants.

> - detailed recipes

How detailed do you want them? I can recommend a few books if you want. Youtube helps too.

> - food 3d printers!

I actually don't know why you want this. Like, are you trying to replicate restaurant food with them? No restaurant I've heard of uses them.

A friend and I built a t-shirt site too. It's so incredibly basic (ours is ugly) but was fun to do to actually write some software for the web (we arent really web guys).

The code is actually really cool because we never have to touch a shirt. Shirts.io handles all the t-shirt fulfillment, stripe handles payments, and we design shirts and add them to the site. If you don't have a t-shirt company, you should, just because it's cool to write a program that turns your own money into tshirts.

I originally was going to sign up for a debit red card, but they wanted a voided cheque for my account. I don't even have any cheques for my checking account so thankfully I opted for the credit option and got a decent limit.

Going forward, I doubt I will ever decide to link my actual bank account to any retailer cards in the future. It's safer, in my opinion, to just use credit for everything since if that card is compromised it's the bank's money that is being taken and not the actual money directly from my bank account. Which results in less consumer inconvenience at least for me.

Venture Capitalist is the best source of funding
I saw this Youtube video that talks a lot about getting funding through venture capitalists. Money is always a struggle when you are starting out. https://www.youtube.com/watch?v=0WiJL1kJw-0
I think people see what they want to see.

If you've attended a few tech/startup events in San Francisco, you'll know that a significant number of "founders" don't have any funding for their ventures and are hoping to raise capital because they don't have any money of their own. Even those who have raised money and can pay themselves a salary earn far, far less than the doctors and attorneys they could have gone to school with.

If the author truly believes that "founders", including the wantrapreneur variety, are being worshipped, I'd suggest she look at where and with whom she spends her time because it's likely more a product of that than anything else.
I had to call Chase last night to get them to approve an eBay transaction I was trying to make. In total, I waited about 45 minutes to do what normally takes about two.

My feeling is that Chase would rather inconvenience their customers than lose money from reversed merchant transactions. The burden of this mishap got placed largely on us, the consumers. Target is getting off easy at this point.

Once you're done stroking your outrage gland, you might note that I didn't suggest an equivalence between these researchers and, well, anybody. I was talking about ideas made appealing by ignorance, ones that are dumb only in retrospect.

The patent medicine Byers took was legal. Indeed his doctor recommended it to him. Unsurprising given that its seller, William J. A. Bailey, offered doctors a 17% kickback to prescribe the stuff. Even after this product was banned (because it finally killed a rich guy?), Bailey was never prosecuted, and continued to sell radium-related products after this. He died wealthy and free at the age of 64, nearly 14 years after killing Byers, and who knows how many other people.

It's a fine example of what I was talking about, where erring on the side of the shiny and new was not a good heuristic; the people who stuck with the traditional and natural did better for themselves despite Bailey and Byers surely scoffing at them.
Not sure if it's related, but today, at 12:45PM (on a Sunday), I went to the local Chase branch (in San Jose) to withdraw some cash from the ATM. The branch was open and staffed, with tellers assisting those customers who needed to withdraw more than $100. I thought that was pretty cool.

If the grid supply goes down for some reason (natural disaster, car hits transformer, significant sustained overload blows pole fuse etc) then everything connected to the grid in that area will see some or all of the following effects:

* sudden change in supply voltage
* sudden change in frequency (and rate-of-change of frequency)
* sudden change in phase angle

You can't mask these signals and they are particularly pronounced on the section of grid that was affected (i.e. the part that is now blacked out). These (and more) are the specific effects that inverters monitor for, and they will disconnect if they notice anything unusual. Inverters aren't checking for the presence of a grid supply, they're monitoring it's health. Your local lines company dictates the trip limits based on your address and size/type of installation.

As for safety, compare some scenarios that a lines worker could actually find himself in:

1) he has turned up to a fault and found that a HV line is on the ground and the auto-recloser is still trying to re-liven it at periodic intervals. The voltages are so high that walking anywhere near the fault could result in him being electrocuted due to a step voltage. The power levels involved are high enough to cause a major explosion.
2) he has to open or close a circuit breaker in a switch yard. He has no way to know whether the breaker is going to explode when he racks it in. At least he probably won't know about it if it does blow up.
3) he turns up to a fault on a 230V line, tests it and finds that there's still voltage present despite the earlier fault. He visits the houses connected to that part of the circuit who have a grid tied inverter and manually isolates them before investigating further.

That last one is hypothetical, since I've never heard of an inverter failing to turn off and even if one did stay on initially it would very quickly trip on overload after trying to supply your house and your neighbors all by itself.

Testing the safety of a circuit before you work on it is an everyday part of the job for electricians. Finding that a circuit is still live is very common, and having one re-liven unexpectedly happens too from time to time. You just take precautions, wear protective gear, and do your best to minimize the danger.
You should look into flashing your ECU. In additon to substantial power increases, there is a dramatic improvement in MPG. I can cite 35 MPG in a E60 535i (+200lbs over an E90 335i) on highway trips when in 'fuel economy mode'.

This third party keyboard on Android was so popular and influential that Google finally added swype like functionality in the base OS (I think starting with JB). This is one of the biggest frustrations I have with the iOS experience (whenever I do use iOS, e.g. on my iPad).

Why not just issue new cards?

I recently received a new debit card from my bank... Claiming they had 'detected a problem with my magnetic strip', which seemed spurious as I had never detected any problem with using the card. When this happened before, my old card continued to be okay until I activated the unsolicited replacement. This time, I was denied use of the card at two stores before I called my bank, who told me the card had been suspended - by the 'anti-fraud unit'. They didn't wait for me to confirm I received the new one by activating it.

I had indeed used that card at Target in the past three months.
