Her recommendations are poor. You dont read books on software development methodologies when "learning to program". Nor would you learn type theory. That's like suggesting to someone who wants to learn to sail, the intricacies of weaving cloth fibers into a sail.

There's a huge tower of abstractions to deal with in learning any new discipline, and it's important to enter at an appropriate level, ie, one that engages the learner to continue because the relationship to the end goal is clear (to the learner).

I would suggest CLRS to someone mathematically mature for the best introduction to algorithms. I don't have a book suggestion for learning to program in some language, but I do consider this a far less difficult and important obstacle compared to learning to think algorithmically.

When the interest is piqued people will naturally dig deeper and eventually find out for themselves, other aspects in the tower, be it silicon doping or reinforcement learning.

Yeah. I love their commitment to privacy and security, but I only wish their platform wasn't so locked down. The only reason I went with Android in the first place was so I could side-load personally-built apps. IIRC (I could be wrong), if you want to write and side-load your own personal iOS apps, you have to pay a $99 fee and they deactivate after a week.
Hello there! Author of the article here. I love the point you've made. Often there are long term costs in e.g. technical debt.

I assumed in this article that the stakes are low (and they are more often than we think) but I have a future article in mind about how to make team decisions when the stakes are high, and it'll be something along the lines of: Have a strong process, and make it the responsibility of one person to follow the process, which should involve gathering information and driving the consensus of the team on that issue. Give that responsibility to someone already established to have good people skills e.g. a lead. What would be your approach?

I'm curious why there are more than one public health system. There's the VA, the IHS (Indian Health Services), and of course medicare/medicaid. Why are these not all the same system? It's not like we're different species....

edit, If this is a benefits/paperwork thing, then shouldn't that be separate from the care provider network?
Excellent. We are in agreement that the American government can and does provide a health insurance program that covers lots of people and has the property that people don’t seek to leave it.

Perhaps the idea that everyone be covered in such a system is not so far fetched.
I originally wrote a long reply, but my damn tablet crapped out on me and I lost it, so my apologies for the brevity here.

Object Pascal will do most of what you want ( c) with VM interop is an issue, but will be for most languages), and is available on a lot of platforms.

On native platforms, you get straight-up manual memory management of class instances (Create/Free methods) or alloc/free memory directly.

On VM platforms like the JVM or CLR, or LLVM-backend compilers that use ARC, the Create/Free methods for class instances are typically mapped to Create/Dispose methods so that non-GCed resources can be disposed of properly.

Things like strings, dynamic arrays, and interfaces are already reference-counted and don't use manual memory management, but can be move'd, etc. and dealt with like normal blocks of memory on native platforms.

There is also marshalling for lower-level access to C APIs from the VM platforms and LLVM back-ends, and direct call access to C APIs from native code with various call modifiers.

There are also some neat things for native platforms like methods for hooking class instance allocation so that you can provide your own per-class memory pools.

The only downside is that you may find some syntax differences on certain platforms, and besides Free Pascal, the compilers tend to cost $$$.
Yea this seems to be a very light (i.e. missing tons of options/explanations) version of privacytools.io.
Obviously, I'd like everyone to be healthy and with an affordable education. But our universe is finite and someone has to pay for these services. Just blindly assuming we can tax all wealthy people into total equality seems like a pipe dream to me.

Hence, I'm arguing that instead of just blind wealth transfers from one group to the collective we should focus a lot more energy on bringing the cost of care down.

Just like we should be focusing a lot more energy on bringing the cost of college down.

> seccomp-bpf doesn't let you follow pointers, so you can't even implement most pledge() restrictions in it. For instance, pledge() always permits open("/etc/localtime"), but at the point seccomp is run, all you know is open(some pointer to userspace).

This is something that is being worked on (separately but similar to Landlock) in the form of seccomp syscall emulation (I don't remember the actual name of the patchset at the moment but it was proposed a month ago I think). However after talking to some seccomp folks I was told that in theory eBPF maps could be used for this purpose (though I'm not really convinced to be honest).

The real downside of ptrace is that you cannot filter which syscalls you're interested in -- so you pay the price of tracing for every syscall. seccomp doesn't have this problem.
Of course its not a sincere argument: I believe that you can believe it, but its insincere at least to yourself to say that the reason healthcare should be universally provided through government is for the poor. If you cared for the poor the argument is to make food stamps for healthcare services, not universal. Universal is also for yourself. So yes, it is disingenuous to say that which is best for your is also best for the poor.

Reminds me to the typical argument that college should be free so poor people can go, but ultimately, middle class and up go. Healthcare is similar: the richer live longer, which means they live more of the most expensive healthcare years.

Tim Cook made it clear be thinks that no industry should have any regulation, especially his (technology, privacy, consumer hardware, should all have no regulation, he thinks!). He thinks Facebook should have done what it did - no regulation is best regulation he says.

No, Tim Cook is exactly as insane and rogue as the rest of them. He is just doing what he can do make Apple the most money. He is not full of common sense. On the contrary, he's basically insane.

Apple should be regulated. So should every industry. If you're a CEO and you think you shouldn't be regulated, it's clear you're out for #1 and #1 alone.

Apple is not some saviour of the universe. They're just making money, and should be critized, not apologized to!

> ...this is a time when Amazon is pushing innovations that don’t solve any real-world problems but may create some: like smart speakers, with their threat of big brother-style surveillance in exchange for a minimal increase in convenience, or complex and expensive cashierless stores that won’t deliver much of an improvement to our shopping experience but may cost underprivileged people their jobs. This is a time when an entire driverless car industry is trying to convince the world that its products are safe before it can even come up with convincing stats – or prevent deadly accidents like the one in Tempe, Arizona earlier this year. This is a time when Google is trying to subvert new privacy regulations to turn them against content producers. A time when Facebook, blasted by media and regulators for ignoring people’s privacy concerns, starts a dating service which will collect people’s most intimate data.

That is a really pointed indictment of our current industry. Wow.

I don't agree with some of the assumptions, but it really points to how rarely an innovation like the iPhone really occurs.

> Do Medicare recipients seek to leave it? That’s a government run healthcare system.

Since you asked - yes, yes they do. Medicare patients can opt to receive their inpatient/outpatient benefits from a private insurer in lieu of traditional Medicare benefits, and an increasing number of people do so.

Privately managed Medicare plans, incidentally, outperform Medicare on the three key performance indicators: medical outcomes, cost, and patient satisfaction.
I'm really curious to see actual performance benchmarks, and to understand where the majority of performance is lost.

Good, I have been debating between running my own k8s on DO vs GKE. I'm glad I don't have to build my own cluster. I think I'm going to do both for now tho. If DO is mature and stable I'll kill the GKE cluster.
Ah, I remember. I had the model wrong. I was trying to view the HTTP payload of a remote client connecting to a remote server. We were trying to debug what was happening when clients were connecting to some enterprise appliances we didnt have the keys for. It has nothing to do with web development, but I mis-remembered what it was I used to work on. Ooops!
(As requested, I work on this project.)

To correct one misconception, the project is not bound to ptrace. There is a generic platform interface, and the repository also includes a KVM-based platform (wherein the Sentry acts as guest kernel and host VMM simultaneously) described in the README. The default platform is ptrace so that it works out of the box everywhere.

> What are your plans to deal with the overhead and nastiness of ptrace? Beyond the performance losses, there's also the annoyance that you can't ptrace a single task twice, so no debuggers.

It's true that you can't trace the sandbox itself, and that's annoying, but you can still use ptrace inside the sandbox (ptrace is implemented by the Sentry). Just wanted to make sure that was clear.

> Are you familiar with the FlexSC paper? Have you considered using a FlexSC-like RPC interface (a secure one, of course) to achieve your syscall interception, instead of ptrace? That would allow you to not just match the performance of native system calls, but even theoretically exceed their performance, while still having the same level of control. (I have been working on such an approach, so I was excited to see this gvisor project posted - I hoped you might have already done this and saved me some work :))

I am familiar with FlexSC. There are certainly opportunities for improvement, including kernel-hooks, shared regions for async system calls, etc. Given the pace that this space is evolving, our priority was to share these pieces so that we can discuss things in the open. While I don't think we'll be able to save you work (sorry!), we're aiming for collaboration and cross-fertilization.
That's the problem! Hospital overcharges because government pays less than the cost of delivering care, so costs have to be recouped from other sources: privately insured, and uninsured.

The one caught in the middle is the individual who gets screwed by both the hospital and insurer/government.
I've been an Android user for years; I recently decided to change to iPhone, and this article really captures the reason why: Apple seems to be the only company for whom a cloud backup of my phone book is a liability, not an asset to be monetised.
It is kind of amazing how much the landscape has changed. I have always used Apple computers and phones, and I used to view Apple as a vaguely sinister company, but one that produced the best products. It is very weird to me that they are now a model for non-evil practices among large tech companies.
Economically speaking I am ok with that. Easier access to a product universally will lower its cost per consumption on average even if that average is a price spike for certain locales. This is a way of saying the outcome benefitting the most people isn't necessarily universally beneficial.

Now I'm all for this at -O1 and above, but having this enabled by default and -O0 [0] is just reckless. Default/-O0 should consist of only completely safe transformations like constant folding, with UB-based stuff only performed when optimizations are explicitly enabled.

Wow good points. I’m sure those tens of thousands of people a year who die due to lack of health insurance are so glad nobody got coerced into helping them out. What a useful definition of liberty, that allows the richest country on earth & in history to deny its citizens preventative care so that they end up dying of easily preventable diseases. We have the liberty to beg on GoFundMe! Health insurance companies have the liberty to insert themselves as middlemen to suck up profits for pushing cash around and denying care!

To not quote a fucking TV magician, “Why not err on the side of every first world nation except us?”.
OK. An ER is a very expensive facility. It is fitted out with staff and equipment to handle almost any conceivable trauma or life-threating condition. That all amortizes into a baseline cost-per-patient. If you go there for something that requires just an ice pack, you are wasting a very expensive resource.

It's like calling for a helicopter to take you across town and wondering why it isn't as cheap as a taxi.
This is a lie. By virtually every measure the VA is the most cost effective and best quality care that Americans can get.

* The VA is very cost effective. It is much cheaper than any private sector health plan or Medicare. Instead of buying into the propaganda go straight to the source [1] and look at the actual facts.

* The VA enjoys very strong customer satisfaction. You wouldn't know this because the media and conservatives work together to denigrate the VA every chance they get but you should actually talk to people on the VA plan. Surveys of actual VA customers [2] indicates they're quite happy with their free, comprehensive government healthcare. (Shocker.)

* Study [3] after study [4] has shown that VA hospitals are better than private, profit-driven hospitals.

Most Americans would kill for VA coverage. It far exceeds anything they will ever receive unless they make it to the 1%. And this is why it's so very important to keep spreading this lie that the VA is this gross, evil system where all the patients are just waiting to die and ignored by incompetent and indifferent government bureaucrats.

And this is the real problem. You can't have real discussions about health care in America because, frankly, most Americans don't live in the real world. They've been led to believe objective nonsense and you simply can't build anything off such a foundation.

Your getting downvoted for this, and I have no idea why.

Have other folks actually stepped inside a VA facility? Many of them are old/outdated/underfunded it's true. But some of them truly do offer superior care to a typical private hospital (in staff, facilities, and outcomes). The VA system could use significant improvement, absolutely. But if the fear-mongering 'worst case scenario' is that everyone gets VA levels of healthcare, that's still a huge win for all of America. That's a great baseline standard to start with, that no one should ever fear falling below.

If an uninsured American is critically injured, the options today are "A: Die" or "B: Bankruptcy". Having a new option "C: Universal VA-levels of healthcare" would be a win for literally every American, even for Americans who are lucky enough to already have great private insurance and who would never need/use this option themselves.

> They don't face financial ruin, unless they don't have health insurance

In the age of high deductible plans I'm not sure this is accurate. For many Americans the $5,000+ for a deductible each year is unsustainable, especially if someone on the plan has an ongoing issue or they have to meet the deductible multiple times (changing jobs or an issue than spans calendar years).
I think the point here is that Apple is not innovating in "stupid" areas(for the author) - like cashierless stores, automated cars, surveillance speakers etc.

In a way, yes, that is admirable - I think all other tech giants are going in the "wrong" and harmful direction, while Apple still concentrates on making good hardware with matching software(their abysmal attempts at MacOs fixes notwithstanding).

> We _ALREADY_ spend more than enough on healthcare as a nation to fully fund healthcare for everybody.

I would like to see a study or article demonstrating this. Do you have any links?
> I'm certainly paying my share.

That seems very hard to determine, especially as a business owner. What's the value to you of safe shipping lanes to get raw materials to you? What's the value of employees not worrying about being executed by warlords? What's the value of having US customers who can afford your products?

I don't think you can say what your "fair share" is as some limit for what you pay. Rather, the amount the businesses are taxed has to be a matter of pragmatism.

> I would bet anything the amount I paid in penalties is more than what most people pay to be insured

One would hope so. That is the point of penalties, after all.
You are right in that ptrace is slow and nasty. The key problem, I believe, is the tracer-tracee mode that involves two host processes and the switch is asynchronous (ptrace(SYSEMU) and then waitpid).

We do have the KVM platform that offers the synchronous switch, which performs better if you have bare-metal virtualization support.

I read the whole article and I'm not impressed. The crux of the article seems to be that he now admires Tim Cook and Apple because they don't spend money on progressive technologies that have a potential for harm. His examples include smart speakers, driverless cars, and cashierless stores that presumably shouldn't be pursued because of their potential for societal harm. Look, things like privacy, safety, and job opportunities for the underprivileged are immensely important, but his arguments are flawed. By the same standards, the iphone and a myriad of other important technologies should never have been pursued.
> No, because it's free, but 1/3 of Medicare recipients opt to receive their coverage through private insurers that typically add on additional coverage

They don't simply add on coverage; they replace it. Most people on Medicare Advantage don't opt for coverage above what Medicare itself can provide - they simply receive their benefits from a private entity instead of Medicare, because Medicare provides such a bad experience for patients.
> because it's the only option that takes privacy and security seriously right now.

iPhones are a luxury. If you can recommend them it means you already belong to the richest part of the planet. For the rest, they jut can't afford it, and Apple was never interested in making anything cheap.
