My dad put our only TV out with the trash because it would not turn on. It was a tube B&W model and I fixed it by soldering the power cord directly to the chassis, bypassing a bad connector on the rear panel. I put it in my bedroom and claimed it as mine since it was in the trash. My dad let me keep it for a couple days until my 5 siblings complained. I was 10 at the time.
Not an EE, but I wonder if it is possible to bake into the hardware an LED that activates when the camera is active.

Things that I value when purchasing and choosing clothes:

* I want to avoid lots of decision-making and info gathering.

* I want it to be simple to buy.

* I want not super expensive, somewhat stylish, somewhat innocuous, occasionally things that I find unique and cool.

This seems like it would make all that easier. Probably will not get one because I don't care enough about the whole area, but I could see buying it if I wanted to improve my personal style for whatever reason or was more focused on being fashionable/stylish than I am at the moment.

Basically, Spotify Discovery Weekly for clothes. I doubt it will take off as fast as the Echo and it has more flop potential, because "Semi-weird Camera in your Closet" isn't as established a product category as "Radio in your Kitchen" but I think it could take off and also not be some horrible distopian thing.

An algorithm recommends easy-to-buy clothing for you based on a picture and your personal taste... Okay cool!
I have a modest amount of money in Robinhood. I love the app and they way it has encouraged me to learn about markets.

I started in March of 2016. I was naïve and I made a lot of silly mistakes early on, but I was able to learn a lot of fundamentals when the stakes were low.

I view it more as a gaming app than investing — it's a supplement, not a replacement for investing and asset management.
Once we're saturated enough with solar I can't imagine there being an easier ad-hoc way to generate energy for small groups in the post-apocalypse. I think you're right though that coal is the ultimate society at-scale fallback.
Ask HN: Are there any security issues when connecting linux to ActiveDirectory?
I work in an institute of a university in Germany, where I do mainly research. Since the institute is too large, they developed an IT-infrastructure which is independent from the rest of the university. The people of other institutes can normally choose which OS they want to have in their computer, but that is not a option for us. We have to use Windows, since all the servers are Windows (crazy, isn't it?) and all what the sysadmins have ever known is Windows. This makes me lose incredible amounts of productive time that I have to put into making things work, which in Linux would be very easy (like compiling some python libraries or automating some simple processes).

I can agree that most people can be happy with Windows, but in research you need to have some freedom to explore different things and not have to lose 3 hours before giving up with the compilation of some cool library you want to try because you were not able to make gcc work correctly in Windows.

Of course I have asked numerous times whether it would be possible to let me install a Linux distribution in my work computer, but they always come with some vague answer about security or that they just don't do Linux. My understanding is that I could not do any more damage that the one I could do with the Windows computer, since the user rights remain the same.

I know that you can connect a Linux computer to a the ActiveDirectory so you can have the same user as in Windows and to access the shared drives and get Email working as well. So my question is the following: is there really a security problem if I do install a Linux distribution and connect it to the ActiveDirectory? And if so, how big is the problem and what would it take to solve it?

Thanks!

> C can be viewed as a pleasant, portable, assembly language.

Do I have to buy what you're on from some guy on the street or is it available as a prescription?

> As such, it lets you "feel" the bare metal, much more so than a scripting language like Python or Javascript.

C hasn't been bare metal since the PDP-11. There are like eight layers of abstraction between

char *foo = "bar";

and the "bare metal"; I don't know why people are desperately clinging to this "C is basically portable assembly nonsense".
I find the arguments for "taking a stand" quite weak. Normally with subcultures that break the law or in other ways inconvenience people the moral argument is that you're doing something that isn't available to you (often as a group) and your actions themselves are meaningful (often because it makes it available to you).

I don't really see in this case how they (or mostly anyone) is unable to improve IoT (or general) security through other means or that the consequences of the actions themselves are any different from other forms of attacks on software (like credit card fraud, denial of service or ransomware).

The arguments from the "hacker" gets especially weak when they conclude that consequences of breaking IoT devices is worthwhile, but the consequences of IoT devices breaking the Internet doesn't have the same effects. Even though you could argue that it's far harder for most people to influence overall Internet security than IoT security and therefor the moral arguments for breaking the Internet as a way of improving it should be slightly easier to make.
"It's all fine and well until one of those improperly configured devices are a medical device or something critical. "

It would be their fault. High-assurance industry has been telling SCADA and medical industry to get their shit together for a long time. This included pentests showing it could all be destroyed. They even have people at conferences talking about it with products or basic advice to deal with it.

The reason it's all still vulnerable is that they... don't... care. They turn whatever small amounts of money the security would've cost into profit. I mean, in some cases we're talking about remote monitoring that operates one way that could be done with a data diode for nearly impenetrable security. Cheap as hell if you homebrew it on cheap, embedded boxes. Likewise for FOSS VPN if two-way is required. Instead, costly system connected to wide open Internet to save a few hundred dollars. They just don't care.

So, you have to make them care. The customers don't as much since they often don't know better. Those that do are apathetic since it will be someone else's problem. That's best moment for regulation to step in to force a solution. There's no regulation, though. Court's seem unreliable on this but still some hope there. So, your options are waiting for them to hit you, paying exhorbitant costs for DDOS mitigation due to problems others are creating (i.e. externalizing), or maybe a criminal just smashes the insecure devices until people stop buying them or manufacturers start securing them. So, I like what's going given nothing else is reducing risk as effectively.

> It could never be licensed in a way that prevented the patch set or the resulting patched kernel source/binaries from being covered and distributed under the GPLv2. If that were the case, the kernel would effectively not be covered by the GPL at all.

Is this true? I would think that as long as your "new" code is sufficiently distinct from the stuff you're replacing, you'd be fine distributing a non-GPL patch (at least if it's e.g. purely positional to elide context related issues). The result of applying the patch would not be distributable, but I'd think the patch itself would be fine.
Can anyone 'in the know' explain to a layman why the parent comment is no reason for concern (especially when it comes to 'non-ionising radiation'?)
> The other thing I see that fools people with experience from other languages is that the "nil" pointer is not the same thing as a NULL pointer in C. In C, the NULL pointer is simply a zero with no type information connected to it. In Go, pointers are actually (type, address) tuples, so a nil pointer to a custom struct is actually (pointer CustomStruct [1], nil), which means that the runtime is capable of correctly resolving methods on nil pointers and that you can therefore write methods that work on nil pointers.

This paragraph seems, at best, misleading. C NULLs are not untyped either (using the same asterisk-avoidance as you): `T pointer x = NULL` means x is a NULL pointer with type T. Similarly, a Go `var x pointer T = nil` is a plain pointer-sized object with all bytes zero, just like C.

If you're talking about interfaces, then, there's actually two sorts of nil interfaces: interfaces where the data pointer is nil, and interfaces that are completely nil (both data and type/interface-info pointers).

func main() {
var x *int
var y interface{} = x
var z interface{}
fmt.Printf("%v, %v, %T, %v, %T, %v", x, y, y, z, z, y == z)
// <nil>, <nil>, *int, <nil>, <nil>, false
}

In any case, for a comparison to C, Go is fairly similar: you can call functions with nil pointers in either, just fine, and dereferencing one is bad (the badness is far more controlled in Go, but see below). For a more reasonable comparison about methods, C++ could make it legal to call methods on nil/NULL pointers, and, like a completely-nil interface, crash when calling a virtual method (i.e. one that requires dereferencing a nil pointer to get the function pointer), but optimisations win out.

> they are not bad in the C sense that any attempt to touch one is a segfault

Note that this has nothing to do with nil pointers storing runtime types (even if they stored them) or anything like that: the Go language just (sensibly) decided to not have undefined behaviour with nil pointers, requiring that implementations handle them in a reliable/reproducible way.
A bad engineer who delivered a difficult project on time with zero support from everyone who was supposed to help me? lol.

Don't believe the hype, just because management says someone is shit, doesn't actually mean that. People have lots of ulterior motives.

Did it occur to you that because my old boss was demoted suddenly and made an engineer (vs manager) that our team head count was now over budget, and they had to get rid of someone?

And to answer your intelligent followup question, No. they didn't even put out a req for that position till a few months ago.

Last I checked, Lending club still had strong returns, even after their fees, for investors (though somewhat less attractive then the figures would suggest since it is taxable as personal income rather than capital gains), and a sub-5% default rate. This characterization seems to be pure fantasy.

Here's an example of how badly active funds underform passive funds:

'Given that active managers’ performance can vary based on market cycles, the newly available
15-year data tells a more stable narrative. Over the 15-year period ending Dec. 2016, 92.15% of
large-cap, 95.4% of mid-cap, and 93.21% of small-cap managers trailed their respective
benchmarks.' [1]

The question folks need to ask is this - Will my stock trading strategy + low (zero with Robinhood?) trading fees outperform 90%+ of the top fund managers who are using the most sophisticated investment tools available? If not, just buy index funds and spend as little as a few hours / year managing your investments :)

Snyk introduces security monitoring for serverless applications
About a decade ago, there was a book written which looked at the ability of Great Britain to become self-sufficient entirely in renewable energy (https://www.withouthotair.com/ looks to be the URL).

It concluded that there is literally not enough renewable energy potential in Great Britain (e.g., cover every square millimeter of space with solar panels) to do so at then-current energy consumption rates. It also pointed out problems with approaches like "giant solar fields in the Sahara" (the requisite solar fields are, well, roughly the size of Germany in terms of required area). Nuclear is technically not a renewable energy resource, but it does have requisite power generation capabilities--and very staunch anti-nuclear activism that makes expanding nuclear difficult.

All in all, quite an eye-opening read.
Oh man! I read through what is an otherwise thoughtful article and get to the end where the author attempts to tie Brexit, and the utterly failed campaign by Hillary Clinton to his main theme! What...the...hell?

Once again an elitist asshole outs themself without even trying! Look, if you want to know what is behind these populist movements, look no further than wealth inequality, Mr. $700,000 last year, snoot snoot!

I don't even know anymore. As someone who grew up pretty lower-middle-class, I can tell you that much of what he says is true about poverty being a self-reinforcing problem and how one's mental state is affected by uncertainty. I can also tell you that luck has played a part in all rags to riches stories, which is why I dislike the entrepreneur narrative--it is largely false for 99% of people. But this hasn't been any different throughout the entire history of humanity! America once may have been an exception, but not anymore. That is very unlikely to change, no matter what social program are put in place, no matter how high taxes are.

But to construe the fed up dregs of the world who are sick of globalist social-engineers and banker scum ripping everyone else off with the type of bottom-barrel risk-taking behavior of the lower classes, that is just too much. Clinton deserved to lose for so many reasons not associated with poverty and there was no time at which she was ever going to do anything positive for the American people versus the corporations, NGOs, and foreign governments that filled the coffers of the Clinton Foundation.

That falls under "rhetoric" the author takes a small unit of time "when sun is shining and wind is blowing" to then use the word "free". Thats cherry picking to the extreme and rhetoric 101. It is used to paint a picture that does not really exist. What happens to solar and wind when its night and the wind is still? By cherry picking and creating a scene which doesnt truly exist it paints a false picture of the efficiency of solar at this moment. Hence why I used "rhetoric".

I could also say that is a falsehood in the practicle sense because of what it left out but that wasnt my original intention. My falsehood statement was to include the part about shale which since shale fields are limited its simply not true.

We could further get into UV rays breakin down solar panels etc but that really wasnt my point. I dont expect people to see the rhetoric and falsehoods used in this article but it stood out to me like a sore thumb so I commented.

Nor was I somehow saying save coal or coal is more efficient etc. It was only a comment on the rhetoric and falshoods I saw in a very short span of words.

"I don't really see in this case how they (or mostly anyone) is unable to improve IoT (or general) security through other means"

Really? How about you show me the evidence that people are... through "other means"... improving IOT security of these devices enough that DDOS isn't a big problem any more. I'd love to hear what you've done to convince all the vendors to focus on secure devices instead of profit when targeting markets that will deliver profit regardless of security. Most of us in INFOSEC haven't been able to convince much past a subset of software and hardware developers to focus on improving security.

The only time vendors ever delivered secure or safe solutions was when sound regulations were forced on them with a requirement they were followed before a purchase was made. That was TCSEC and DO-178B respectively.

If some of the components are sourced used, then the price for this could easily be <$1000 for the core components, though you could make this cheaper with a different CPU and GPU, cheaper memory, see below:

(prices estimated from eBay)

------------------------------

CPU, fans, cpu cooler, motheboard, RAM, PSU, GPU (comparable Radeon 280x)
$865 +/-$50 (shipped)
Note: a cheaper CPU (+overclock), a different PSU (500-600w would be fine for this system), cheaper ram (+overclock) would net a $100-200 savings for nearly identical performance

Case (Silverstone fortress FT-03)
$200 est

Apple-compatible PCIe wifi card
$130 shipped

Storage, speakers, mouse/keyboard, and display vary by user needs the cost here could be $200 or less for cheap/used components or $10k for color-accurate panels, audiophile speakers, custom mechanical keyboard, multiple PCIe SSDs, etc, etc

------------------------------

TL,DR - let's assume you're will to source some used components and go the cheaper route on a few things. You already have access to a screen, input devices, and speakers. In this situation, you could build a comparable machine for under $1000 + the cost of whatever storage SSD/HDD you need. You could stay under $1000 for the whole build if you opt for a cheap case and a single SATA-based SSD.
So you think northern African nations are going to let European nations station troops there and take over a big chunk of their land? That doesn't seem realistic, and seems rather imperialistic actually.

Letting the northern African nations provide the security is just plain folly, and also makes Europe completely dependent on these economically backwards and frequently hostile nations.
