Forwarding a random email conversation from a year+ ago without any context to public mailing list that is read who knows how many people just to get it into an archive so that you can link to it in HN comment does not really help your case

The modern Firefox solution are the containers mentioned elsewhere in this thread. Basic UI for that feature is part of default install, and that basic UI covers exactly the work/personal/banking/porn usecase. Also, Firefox s

Well it is probably somewhat depatable as to how much one should care about calibration of an CRO, especially today. The precision is somewhat inherently limited by what you can resolve with Mk1 eyeball on the screen. I have an 4 channel Ke

If you come from a unix background the Meson/Ninja combination (more or less autotools without legacy crud) is probably more approachable than CMake with all of its implicit magic.

The backdoor in DualEC_DRBG only works if there is some way for the attacker to directly observe its outputs (eg. using that for IVs). If you use it as an inner CSPRNG that seeds other faster algorithms the backdoor is irrelevant, but well,

In the various libertarian ideologies there is the idea that only thing that government needs to do is to “notarize” contracts. This is on the first approximation true, but said government needs to somehow derive the authority to do so. Tha

The solution for right-angle plugs blocking adjacent sockets are angled sockets. For a correctly designed appliance the polarization should not matter and as today most appliances have CEE E/F plugs which are compatible with inherently

Except Hash_DRBG is neither deprecated nor backdoored. See NIST SP 800-90A Rev. 1 section 10.1.1.1 for description of the algorithm.

ASN.1 in itself is a schema syntax. That schema can be serialized into various related forms, but all of them are more or less a transport formats that cannot be reasonably used for random access. There are some more or less general hierarc

The specification is massive (840 pages) even though it is written in very terse way that does not really specify the effects and behavior, only the syntax. On the other hand if one ignores few warts (explosion of local styles and text span

As for [1], it is not really hardcoded, but depends on what is the value of localeconv()->decimal_point, if it is “,”, excel uses semicolons both in CSV files and formula expression language. This used to be configurable when opening CSV

That is common for codec standards, the normative part of many MPEG specifications is the parser/decoder in C-like pseudo-code. What is somewhat unique for Xiph is that their normative reference decoders are actually usable.

The solution there is DDNS, which is one of the things behind MS AD and just works, and configuring that on pure Unix infrastructure is surprisingly easy.

That is essentially an reaction to random middleboxes just plainly droping ICMP traffic. If you want to stuff to work you do not want to just drop ICMP. The sane policy is to just pass it through or maybe rate limit it.

Many contemporary computing platforms have some kind of HW RNG built into them, these are often regarded with some kind of skepticism as they are not really auditable. The larger issue is that these are not really needed, any device that do

It depends on both issuer, acquirer and the particular merchant. Second step of the EMV transaction (after the terminal verifies that the card was issued by known issuer) involves the card and terminal comparing their authentication and aut

IIRC the powering on by WiiMote is handled by the BT chipset which stays powered in all power states and in the normal standby mode wakes Starlet with dedicated GPIO line. Also, while the WiiMote is more or less an compliant BT HID peripher

The split phase arrangement comes from Edison's DC systems. For large installations they found out that the losses were unacceptable and solved thet by running the lighting on 220V with sets of two 110V bulbs in series, usually combine

Even if it is really reviewed it is reviewed by somebody who is part of the recent (5 years or so?) explosion of “cybersecurity” and thus incentived to overblow the issue.

Well, the lucky part is the important one. What it boils down is that such system is either self-contained or has rigidly defined outside interfaces. For anything that deals with a physical reality outside of the pure computational realm th

Well, all of the 3GPP mobile networks switch to a different logic for emergency calls. In the GSM case all emergency calls (112 is hardcoded in the specification and there is a provision for both USIM and the network to add more numbers tha

And as for some additional context: before multi-constellation GNSS receivers and such stuff, multilateriation from GSM timing advance was a somewhat good way to get precise position fix, especially with GSM PLMN that has additional support

The network simply has to have a pretty good idea of where the given MS is and how fast it is moving in which direction. The network maintains some kind of CDMA/OFDM/whatever radio link to said MS and thus either has to know that

The TIs have much more sane programming language than Casios.

Well, exactly. While there is a way of getting some of the stored energy as an controlled power, most of the failure modes of such a thing leads to uncontrolled release of the stored energy, manifested by the whole thing just somewhat insta

The updated preprint gives Tc of 104.8 degC. I am not a material scientist and do not know much about superconductors, but cursory glance on some of the charts in the paper suggests that the real Tc of sample they measured is somewhat lower

There is a theory that with room temperature superconductors you could use an inductor for practical energy storage.

Well, the article itself does a pretty good job of describing why it is not an exactly good idea. What it does not say (and what probably nobody suggesting that ever though about) is that the sky-wave propagation mode is either about reflec

That seems like ground based interference. Today a lot of stuff, including components of the drone itself, can be unintentional L-band radiators. Getting what is probably the cheapest tier of spectrum analyzer and investigating that behavio

That depends of what exactly is that anomaly. If your GNSS receiver tracks 4 satellites from the same constellation then obviously, this kind of ionosphere anomaly will with some probability lead to some kind of unexpected fix error (but wi
