_red··on ARM processors like A12X are nearing performance parity with desktop processors
Great. But you seem to have missed that I was just providing an example.

However, to further the requirements. These days many people throw around the term "ATM" sort of indiscriminately. So, they call everything from a simple 3rd party cash dispensing kiosk to full-on bank automation centers "ATM's".

The problem is, that for a simple cask dispensing kiosk, you may be totally correct. Linux + ARM may work fine. However, the more functionality this device is suppose to have (ie. do 90% of the functions of a real bank teller: deposit checks, cash checks, etc), then the more these edge-cases become an issue.

Because of this tight integration with backend banking system, and regulatory requirements, these edge cases will become magnified (i.e. who says you can use linux?). Additionally, since all other players in this market also have to deal with all these issues, the $50 difference in CPU cost is totally absorbed into the rather high-dollar price tag associated with this automated teller.

_red··on ARM processors like A12X are nearing performance parity with desktop processors
My company does some embedded work. The problem with your analogy is that edge-cases drive CPU purchase decisions far more often than you would normally think.

A simple example: You have designed an ATM using a lower powered ARM CPU. 99.9% of the use-cases never tax the CPU beyond 30%. However, in specific cases where the ATM must simultaneously access the bill dispenser, printer, and note acceptor the hardware interrupts overwhelm the CPU and leads to 2-3 secs of "CPU lock". After those 3 secs, everything returns to normal.

The problem is that the bill dispenser protocol only allows for 1000ms in delay in ack to messages, thus when this situation occurs, the lag is longer than the protocol allows, so it errors out and FUBARs the entire transaction.

In this case, even though this only occurs .1% of the time, the existence of this edge-case will mandate that you not use this specific CPU.

Spoken another way: The ongoing issue of certain edge-cases will cost much more in the long term, than the extra $50 for a different CPU.

_red··on U.S. users are leaving Facebook by the millions, Edison Research says
You may be an older person, but for anyone with teens an interesting aspect is that they hardly use it.

FB is turning into a "how to talk to grandma" network.

>its clearly possible.

* As a percentage, what share of single-parent homes receive some kind of government assistance?

* You deliberately neglect that most single-parent homes receive ongoing child support from other parent.

_red··on Everyone should read support emails
Who says the ability to "reboot the computer" is avail to the user? (ie. remote RDC connection or a locked down retail POS terminal).

Also, the "real purpose" of L1 tech is to categorize and prioritize incoming calls for further L2 / L3 processing. Knowing "who" needs to handle the call next, and its priority, is usually critical to getting real problems resolved timely.

_red··on Everyone should read support emails
We do retail / light industrial automation stuff.

Every so often (rarely but say once a year or so), we bring some members of dev team along on an install. Its always very very eye-opening for developers to see what 'problems' look like in the field.

Further, something devs miss about installs is the lack of infrastructure you have to deal with (on a new build-out for example). So saying 'Just download latest version X and install on each of the clients' will take 5x longer than it does in comfy office environment since it means: (a) Go to hotel or tether phone and download 1GB file over 3G, (b) Put on USB stick, (c) go to each client, disable all USB restrictions and install new software, re-enable all restrictions (d) do all this while power is being turned off / on because electricians are still working.

_red··on Amazon Removed Anti-Vax Documentaries from Prime Video
You seem to think that the efficacy post-inoculation remains static throughout a persons 80 year lifespan.

That's a very unscientific assumption. Vaccines regularly lose efficacy, which is why 85% for the 'best' is reasonable.

_red··on Amazon Removed Anti-Vax Documentaries from Prime Video
>As far as I know, no one is trying to force the flu vaccine.

Yet.

What do you thinks going to happen once they get the precedent set?

Give it another 5 years or so.

_red··on Amazon Removed Anti-Vax Documentaries from Prime Video
So you're saying: We don't know if its effective, because its really really hard. However, we should make it illegal to refuse.

Its bracing how anti-science you sound.

_red··on Amazon Removed Anti-Vax Documentaries from Prime Video
You like "science" but can't actually read the insert. Why?
_red··on Amazon Removed Anti-Vax Documentaries from Prime Video
Now this is just one vaccine, and its not wise to extrapolate wholesale.

However, this one clearly states: there have been no controlled trials adequately demonstrating a decrease in influenza from using this product.

Note: Its curious I'm being downvoted for actually posted an actual insert, which has real scientific information. You would think all the "science lovers" would applaud that. Ho hum, I guess I should've posted a Merck marketing ad instead.

_red··on Amazon to launch grocery store chain cheaper than whole foods
Its curious because they've already "dumbed down" WF a bit since the acquisition. Lots of the higher end products have been slowly disappearing from the shelves.

I used to make the trek to go to WF in the past essentially for their seafood counter. Now post-acquisition, there is really no need to, since there is no material difference from WF and a regular grocery store when it comes to seafood.

Will be interesting to see how this strategy plays out...will they boost WF foods back into premium territory? Or will WF simply be Grocery+ and their new venture (Half Foods?) will be Walmart+?

_red··on Facebook wants up to 30% of fan subscriptions vs Patreon’s 5%
Its more than that, banking is a legally granted monopoly license (ie. Federal Reserve).

So they are enjoying all the perks of being government backed (protected monopoly + full bailout privileges), yet must endure none of the restrictions of a government agency. Best of both worlds.

_red··on Is Elon Musk trying to commit ‘suicide by SEC’ by taunting the agency?
Because Tesla, as a company, is actually majority owned by the shareholders that make up 80+% of the company.

A very small move of the SEC can destroy those investors chances of ever being paid back.

_red··on Algorithmic Justice Could Clear Convictions in California
How many different sub-variations of "intent" are there?

So if I plan to kill Person A, but miss my shot and kill Person B whats the charge? What if I was under threat by Person A? Who should even be charged for Person B's death...me or Person A?

Moreover, you've neglected to mention that there are all sorts of "human killing another" which are not even considered a crime (abortion, do not resuscitate orders, etc).

>The complexity of the law that people bemoan are not about simple issues like murder, they are issues like zoning laws, tax law

Lets not get ahead of ourselves, we still have barely scratched the surface with the 'easy laws'

_red··on Algorithmic Justice Could Clear Convictions in California
>Killing someone in a bar fight is third degree murder, so I've already covered that

So in the space of a minimal online discussion you've gone from 2 classes of murder to now 5 classes (3 degrees of murder + negligence + under threat).

Now continue this exercise for the next 250 years and you will eventually have a codification of the classes of murder which roughly mirrors our current laws. Which is to say, it will get progressively more complex.

_red··on Algorithmic Justice Could Clear Convictions in California
>There's murder and there's negligence

And self-defense? or any of the dozens of other shades (car accidents?)?

So two people getting in a fight in a bar and one unintentionally kills the other should receive the same sentence as car accident victim? Or accidental sports injury?

You are attempting to simplify the world to simple morality tales. Hope you never have to live in such a world.

_red··on Algorithmic Justice Could Clear Convictions in California
Yes, Law is the nexus where Moral, Political, and Commercial interest all meet. Its going to be messy and complicated.

But, it's common on tech boards to have a very loud minority of autistic-types claim that all these things can be solved by "code".

_red··on Algorithmic Justice Could Clear Convictions in California
Take a relatively grey-filled topic like: One person has caused the death of another.

Now show me the simple law covering that?

People claiming "the law can be simple" are exactly the same as luddites who claim "why cant you just make computers work?!" - each side has no appreciation of the inherent complexities involved.

>I dont know if law can be reduced to code, and it should ideally be intelligible and accessible to the average person, it seems?

Pick One:

(a) There is only black and white - Laws are simple

(b) There are many shades of grey - Laws are complex

You can't have:

(c) There are many shades of grey - Laws are simple

_red··on Roma's Wounding Confession
A close friend of mine lived in Mexico for many years. I would visit him occasionally and spend the odd week or two with him. I got to know his home help.

He being an American of generally liberal persuasion tried, as your family did, to treat the cook and gardener as 'equals'.

Over time that changed though. One day the maid sat him down and politely explained that it was sort of insulting to be treated too familiar in this context. She was speaking of the gardener and said, "What you are doing makes him feel very uncomfortable". She explained, "the old man there is kneeling in your garden pulling weeds 8 hours a day, and you come home...breeze in in your 50K auto and ask him if he wants to share a beer with you..."

He realized she was right. These people were not "passionate about their career", in fact there was no career, nor even the semblance of it. They were just doing whatever possible work they could do to earn enough money to keep food on their families table. Treating them too familiar, or even implying they shared lots of things in common, was sort of demeaning.

In the end, he wound up treating them very formally. "Sr Veracruz" "Sra Sanchez" etc...always keeping a sort of respectful distance between them. Posting work schedules, etc and generally treating them like employees.

I'm not at all against what you said, nor implying you guys didn't do what was right, simply showing there are more than one interpretation of such situations.

_red··on A $10 Accessory Proves Smartphones Are Too Big
The obsession with "thin" has produced devices which are totally unnatural to type on.

My old BB Classic was one of the best pure communication devices I've ever owned. I could write long multi-paragraph emails on that thing hardly ever needing correction.

Many of my clients are lawyers, and I noticed that the legal community was one of the last holdouts on BB platform. Namely, because anyone whose job requires lengthy written communication, it provided the best balance of form and function. Even being careful, it seems impossible to type more than 2 or 3 words in succession without needing to correct something on Apple phones.

Apple has been hiding their bad (near abysmal) ergonomics behind the success of their app store. I wonder how long it will last? Sadly, I think the whole management team now has too much hubris to ever change course and will continue to double-down on ever thinner devices with 1/2 day battery life.

_red··on Ask HN: How bad is freelancing?
I did sysadmin freelancing for a number of years. The keys for me were:

1. Find small to mid-sized companies who can't afford (don't need) a full-time SysAdmin, but could use one for say 2 hrs per day.

2. Be nice and attentive to secretaries and office managers!

3. Push clients to engage in contracts. Offer discounts on hourly rate for bulk commitments (e.g. offer 10 hrs per month at a 35% discount or whatever).

4. You need to oversubscribe yourself about 1.5x to make it work financially...also invest in decent time & billing software.

5. Never pay for advertising. Asking existing clients politely for referrals is 10000% more effective. Further, the kind of jobs you get from "ads in the paper" are never the jobs you actually want to do.

_red··on Saying Goodbye to Louisville
Be that as it may, it doesn't mean its sustainable.

Those "100% speed increases" were ISP's willing to lose some money to retain existing customers in select markets, using their other profitable markets to subsidize them.

I'm 100% for more competition in the quasi-monopoly ISP arena, however googles entree into the ISP market was just freshman exuberance. They were flush with lots of shareholder money and had young idealistic founders who figured they could "revolutionize the space" because they were smart and cared.

Over the past few years, google has been shutting down all their naive money losing ventures and getting into the serious business of making money (ie. selling your personal info to the highest bidder).

_red··on Reddit Set to Land $150M Investment from a Chinese Censorship Powerhouse

_red··on Bye, Bye, Google
Apple's case is slightly more complicated. From 1995-2004 I used Linux, from 2004-2018 I used Mac (whole ecosystem), from 2018 onwards I'm back to Linux.

To be honest my reasons are: I really just think Tim Cook has little to no vision and all their products are showing the effects of "bozo explosion".

Any organization that doubles, triples, or quadruples in size winds up being a giant host to parasitic employees (middle manager bozos, usually), whose basic motive is (a) do little work, (b) get paid. The real world effects is the company stops being able to make decisions and continues to double-down on mistakes (removing headphone jacks to force consumers into buying your proprietary 'ear pods'). All those "one time tricks" to boost revenue eventually run out...ask Balmer.
