BluePen7··on Samsung Busted for Cheating TV Test Benchmarks
I'd also like to know the hack, my buddy's been fighting his Samsung fridge for years.
BluePen7··on Why you can’t buy a thermapen on Amazon (2016)
Same four* suppliers actually, just about every rechargeable embedded battery is made by Panasonic, Sanyo, LG, or Samsung.

Most common type/size is the 18650, used in everything from drills, powerbanks, to Teslas. Second most common type is the 21700.

A "scientific" test isn't even necessary, just tear down the battery pack, see what cell they put in there, and read the spec sheet. The big 4 battery makers will sell you a whole range of batteries in that size with varying mAh/Amp.

Googling teardowns, I found a Black & Decker 1.5A MAX Lithium simply uses a bunch of Sanyo UR18650W2 (1500mAh rated at 18A) cells, while a teardown of a Dewalt pack shows they used the more expensive LG HB4s (1500mAh rated at 30A).

There literally no reason they can't use the better cells in the Black & Decker, other than they're building it to a cheaper price point. The fact that they're built in the same factory is besides the point.

BluePen7··on “About one-third of Basecamp employees accepted buyouts today”
The deal's almost too good to pass up.

I'll program and be professional at company A just as happily as I would at company B.

I'm already professional and apolitical at work, I don't feel I stand to gain much being otherwise.

So I think you'd be inadvertently discriminating against people who are simply interested in getting 2 salaries for 6 months.

BluePen7··on Why Do People Stay Poor? [pdf]
Not who you asked, but without extra means you end up with free time any time you're not working. You can't afford to do anything.

If you don't have a job where you can simply take on more hours, but it's also not predictable enough that you can get a second job, you just end up with a lot of useless free time on short notice.

Can't afford hobbies, trips, no significant other (being poor doesn't help your dating life), what else is there to do?

It took money for me to actually run out of free time. I honestly really enjoy tinkering and fixing stuff, but it's usually no longer worth my time (to my own dismay).

Before money learning to fix something meant the difference between keeping the car going, or having your car break down without money for the shop bills. I've fixed lots of stuff by flashlight so I could get to work the next day.

Nowadays being put in that sort of back-against-the-wall scenario isn't likely to happen, unless I sign up for some sort of game show or reality TV where it's purposely planned.

BluePen7··on Amazon establishes new Counterfeit Crimes Unit
I started following that rule a while ago too, I wouldn't trust some random off-brand food from amazon, but the brand name food has a fair bit of markup.

If the counterfeiters are willing to produce anything to make a buck, and amazon is willing to sell counterfeit goods as legitimate, it makes sense we'd eventually have counterfeit brand name cereal or canned goods.

A while ago my fiancee was having trouble finding some Eagle Brand Medicated Oil (it's this traditional asian stuff her mom rubbed on her), and I saw it was on amazon. It's possible they have changed their manufacturing processes slightly since her previous bottle, or it was different because it wasn't as old, but it just kept being every so slightly different in subtle ways, such as the feel of the bottle and even cap, the texture of the oil, the smell was a bit different, the box was a bit bigger, etc.

I honestly still am not sure if it's counterfeit or not, but that's just the issue, I don't have the means to check. My only choice is to buy from sources with trusted supply chains.

It's ironic, I was the first of all my friends to start using amazon excessively, and got them into it, but nowadays my fiancee remarks she found her workout supplement on there for a few dollars cheaper and I reflexively reply "Hell no! We don't put things from amazon in our body.

At this point I only trust them with things that can fail on their own without causing damage, or for products so complicated no one has made a knock-off yet (I'm waiting on knock-off brand name monitors). They went from this amazing cheaper alternative to big-box stores, to AliExpress with 2 day shipping.

BluePen7··on WeChat permanently closes account after user sets offensive password
They don't need to have a visceral emotional reaction, they just need to know it's a strong anti-CCP sentiment. Given how frequently we use Fuck ____ in English for things we don't like (Fuck Cancer, Fuck the police, etc), it's a pretty obvious one.

I'd also assume they'd assign the english speaking North American dissidents to a monitoring person who speaks good english.

BluePen7··on WeChat permanently closes account after user sets offensive password
After my initial laugh at your response, I realized 7% is about what I'd bet too.

My first foray into options trading I lost around 3% of my net worth, and I'd say I'm more than twice as confident about this than I was about that.

I'd evaluate the odds of the CCP doing something, to be in line with the odds of them benefiting from doing something, regardless of the expense/risk to their populace.

There's nothing I'd really put past them, we know for a fact they harvest organs from political dissidents, but we're skeptical on if they'd store passwords plaintext?

Given people tend to re-use passwords, I'd imagine having a massive trove of plaintext passwords for all Chinese citizens, or even anyone who communicates with them, would be incredibly useful.

Not to mention the fact that they have to maintain a list of anti-CCP passwords, which would be a tedious process, or they'd have to automate something to detect anti-CCP sentiment. I think an interesting experiment would be to see what less obvious anti-CCP passwords get you banned. With enough probing and data, I'd possibly increase my wager to 10%.

As a well known and outspoken critic of the CCP, she might be elevated to the status where they actually just have a person reading everything she types into WeChat 24/7. Do you think they fully staff the night shift, or would the ban have taken twice as long outside of Chinese business hours?

BluePen7··on Slack was down
That's a funny anecdote and a good step, but you guys still have a long way to go in regards to outage alerting at SendGrid.

I was annoyed when after a several hour long outage SendGrid still had not updated their status page to reflect an issue.

But I was even more annoyed when 5+ hours into the outage, a different support person told me they aren't aware of any outage because their status page does not reflect one.

If I sound bitter it's because I am, I was the on call person who got woken up in the wee hours of the morning to deal with this. I'm referring to the outage you guys had in December if you're wondering.

BluePen7··on New 13-inch MacBook Pro
According to the forum posts, it's happening to everyone who uses the default plug, the extension that comes with a 3 pin plug resolves the issue.

I have one short and one long cable, and am only just now realizing the issue. I'd simply assumed the short one was a fake I'd gotten.

Can't speak to why your iPhone and iPad do the same thing, I've experienced it when using sketchy cheap lightning cables or wall adapters (including ghost touching), but not when using better built stuff (like AmazonBasics or Anker).

BluePen7··on The average consumer loses over $150 a year renting a router from their ISP
I don't think there's a legal interest rate that's as bad as paying $150 annually to rent a $100 router, that's basically 150% interest.

So regardless how bad your credit rating and interest rate are, it's overwhelmingly worth putting a router onto your credit card.

BluePen7··on U.S. Economy Shrinks at 4.8% Pace, Signaling Start of Recession
The other aspect is a lot of older luxury cars were also very well built, and older economy cars were some real bare-bones shitboxes.

My father enjoyed driving his Mercedes, so I figured I ought to enjoy a German luxury car as well. I expected to pay a certain premium on parts, and obviously for premium fuel and synthetic oil, but that I'd get a much more solid feeling car in return.

The problem is, the Mercedes he drove were from the 80s and 90s, so parts markup aside, they were basically Toyota reliable.

The German car I bought was from the mid-2000s, and nowhere near as well built or reliable as a 90s Mercedes, even in present day.

I'd even owned a 1986 Mercedes that was still reliable in 2010, I'd also owned a 1992 Mercedes that was also reliable, and continued to be so after I sold it to a friend who drove it for all of university (2010-2015).

But it was the 7 year old one that basically fell apart despite me buying one with full dealership service history, then sinking endless money in making sure all the repairs were done properly with OEM parts, on top of my religious maintenance as I'd believed German cars were only problematic due to neglectful owners.

So, it went about as poorly as you'd expect.

BluePen7··on U.S. Economy Shrinks at 4.8% Pace, Signaling Start of Recession
I think there's two confounding factors there, in the US parking is usually plentiful and right out front (or visible), so you're always seen in the vehicle you pull up in. It can be a part of your identity, both for yourself, and socially.

Americans also spend a lot of time in their cars, I went from a short commute to a long commute (1 hour each way), and found I got almost exponentially more critical of my car the longer the commute.

Suddenly the practical vehicle I didn't mind driving 15 minutes, was an eyesore to look at after an hour, and the NVH (noise, vibration, harshness) wears on you exponentially with time.

I started browsing cars to buy that would have been borderline financial suicide for how much I made, just because of how important the comfort and aesthetics became to me.

Couple this with their tendency towards financing things, and how cheap automotive related expenses are in the US, and it's the perfect storm.

I ended up changing jobs to one 10 minutes from my house, and it's downtown so parking is just done at various pay lots a few blocks from my office so nobody ever sees what I drive, and suddenly what I drive is irrelevant again, I was back to being content with my 15 year old Camry.

BluePen7··on How to burn the most money with a single click in Azure
Not who you asked, but my mistake was transferring an S3 bucket full of unused old customer web assets to glacier, we were paying a lot to host them each month, and weren't using them anymore.

I set the lifecycle rule on all objects in the bucket, for as soon as possible (24 hours).

About 2 days later first thing in the morning I get a bunch of frantic messages from my manager that whatever script I was running, please stop it, before I'd even done anything for the day.

The lifecycle rule had taken effect near the end of the previous day, and he was just getting all the billing alerts from overnight, it was all done.

I read about glacier pricing, but didn't realize there was a lifecycle transfer fee per 1000 objects (I forget the exact price, maybe $0.05 per 1000 objects). That section was a lot further down the pricing page.

The bucket contained over 700 million small files.

I'd just blown $42,000.

That was over a month's AWS budget for us, in the end AWS gave us 10% back.

On the plus side, I didn't get in too much trouble, and given we'd break even in 4 years on S3 costs, upper management was gracious enough to see it as an unplanned investment.

TLDR: My company spent 42k for me to learn to read to the bottom of every AWS pricing page.

BluePen7··on SUVs and pickup trucks are now too big for already gigantic garages
And the lower class, a 4 door 5 seater sedan is what I drove when I didn’t have that much money.

If I’d had more money, I could afford a coupe.

And if I had more money still, I could afford a 2 seater sports car.

An under utilized vehicle may be a hallmark of the middle class, but a desirable vehicle that is only exactly what you need at that moment is a hallmark of the upper class.

On top of being more expensive, it’s also far more likely to be a secondary vehicle.

BluePen7··on Federal safety official slams Tesla, regulators for misuse of its Autopilot tech
> Staying in your lane should be muscle memory for an experienced driver

The amount of effort needed for this can vary wildly depending on the vehicle, it’s mechanical condition, and the speed it’s being driven at. Some vehicles are more prone to being bothered by wind, or grooves in the road, or require more constant adjustments to maintain lane position.

My tiredness is dependant on the vehicle.

I’ve had cars I’m exhausted from driving just after a 1 hour commute, and I’ve had a luxury sedan I could drive basically indefinitely (once did 3000 miles in 3 days, I didn’t mind it at all).

I wonder if the person you’re replying to previously drive a much less refined car, and would see most of the same benefits even when driving the Tesla manually.

Honestly the second part of their focus, simply being aware of their surroundings, should also be muscle memory for any experienced driver. That’s probably why they find driving so tiring, because they don’t plan ahead enough to keep a peaceful flow, rather than slightly too late scramble to gather information when they have to change lanes or something.

BluePen7··on Flash Memory Wear Killing Older Teslas Due to Excessive Data Logging: Report
The other day I was visiting my sister and she asked me to scan the codes on her 2014 Silverado.

When I put the key in the ignition position for on (without starting it) so I could read the codes, it complained that the battery was low, and to start the truck soon.

Oddly enough, my dad's 2001 Silverado always had the same problem (just a red battery light back then), 2 years of ownership so far and it's battery is still fine, same warning right before you start it that goes away once it's on.

When I told this to her she told me her old Jimmy did the same thing.

The code her truck was throwing was coincidentally the same code as my dad's 2001 truck, about the evap canister.

I was flabbergasted, 13 years age difference and this truck was no different.
