It's not easily automated. Somehow, you have to safely get a certificate across the air gap to the internal network. So I guess an internet-connected system grabs the certificates, then they get burned to DVD-R, then... a robot moves t

How could that work? For security, an internal site lacks a connection to the internet.

That is a common problem. SIMD can be slower than non-SIMD. Consider this problem: The goal was to emulate a 4-way PowerPC TLB on x86-64. Four uint32_t values had to be compared to find a match. The data structure was roughly "uint32_t

I've seen that. It was funny. The corporate security team sent out the email. It had a link with no actual content, giving an error, but that got you on the list of people with bad security behavior. The trouble at my office was that m

It'd be less likely than with the currently selling calculators. Are we seeing modchips now? I don't think so. Of course it is always possible to fully replicate the calculator. I'm sure there is a Chinese factory that could

The proper fix is to store user data and run user code only when removable media is inserted. The calculator could hardware-disable flash writes when removable media is detected, and then do a full reset when removable media is removed. Ide

You could use C with the TI-84 Plus CE. That gave direct hardware access to the memory-mapped display. Python is no substitute for C. Languages like C are far better for getting a feel for how computers truly work.

by souprock 6y ago
Yep. The C compiler is fascinating. You get sizeof(int)==3 and sizeof(void*)==3 with that compiler. Alignment and padding do not exist.

That doesn't really work for Monaco, Vatican City, or Gibraltar. War is not cheap. There is no reasonable way to expand London City Airport. Bulldozing London's financial industry to make more room for runways would mean bulldozin

Speaking as a passenger, the right solution is CATOBAR. Passenger airports should install linear motor catapults that can get a 500-ton aircraft up to Mach 0.85 in about 10 seconds. (it can support the plane, allowing launch with already-re

I find that even with 12 kids, working from home is productive. The difference is that I can go do a bit of work between other tasks. If I have an hour to spare and need to walk to work, about 50% of the time would be walking. It just isn&#

For your struggling friends, I found the problem: "career people, and they're still struggling to save much of anything after childcare expenses" That just isn't going to work. It can't. By law in most places, the r

People with different views are on an exponential growth trajectory, so good luck with that.

Heh, it's funny that I'm actually a hypervisor developer and I don't use that terminology. The whole team doesn't. I actually had to look up "type 1" and "type 2" to remind myself which was which. Tho

With the right grain of salt, you get zinc. Suggestions: zinc acetate, zinc chloride, zinc citrate

Nested virtualization only works when the outer hypervisor supports all the features that the inner hypervisor needs. If the outer hypervisor is Hyper-V, then that limits the inner hypervisor to the features that Hyper-V bothered to impleme

First, I agree on the PRI macros. I refuse to use them. Stucture member access by name is useful. It's slow, but it doesn't affect code that isn't using the feature. The worst runtime issue is that the runtime support require

by souprock 7y ago
This is a worrisome development. We seem to be heading toward a future where hypervisor drivers can only be provided by Microsoft, and you're out of luck if they don't do the job. Hypervisors that need more capability are going to

I think sprintf and gets can be perfectly secure interfaces. The standard just needs to specify them in a way that causes overflows to raise signals. This is probably more for POSIX and UNIX, since I think it requires the concept of memory

Everything breaks if it isn't. I was on an OS development team in the 1990s. We were using the SHARC DSP, which was naturally a word-addressed chip. Endianness didn't exist in hardware, since everything was whatever size (32, 40,

Cool. Everybody in the home is already infected by the time somebody needs breathing assistance, so this is fine.

All I ever want to do is use the road. There aren't enough mountain passes. For me, Yosemite is basically a toll road.

I do this. Just yesterday, I changed a large piece of software. I didn't have any source code for it. I think it may have been written in C++, but that didn't matter. I had the *.exe file, which was all I needed. I used IDA Pro to

The real winner for that is probably Binary Ninja. It has a built-in compiler that is well-suited for patching binaries.

If that population center happens to be Iceland, just walk over to the Mid-Atlantic Ridge and hold a radio on each side. That is equally valid for "trans-Atlantic".

That would work. She sometimes puts a large cooler with ice in the van, then uses it to hold food so that she can go back inside for more. I could also give cash to 5 or more kids, then have each one go to a separate checkout lane. All of t

Publix is also limiting cheese. They let me have two half-pound packages, but I wanted about ten packages because I have a dozen kids. The limit for milk was 2 gallons, but I wanted 6. I got 4 by putting them on the check-out counter in pai

I think "the hottest" would be "totally uncool" by definition. Here are a few projects, many unmaintained, which qualify: https://www.archlinux.org/packages/community/x86_64/cpuburn/

There is the general principle. Connecting things to the internet reduces security. You'll get hacked. You should protect your financial information, employee private data, customer private data, and work product. It's especially

I go shopping more because the store won't let me buy enough food in one trip.
