Yes it is possible for a gentile to convert to Judaism (even Orthodox Judaism).
The synagogue will actively discourage the convert (Judaism is *not* a proselytising religion), but it is possible. A friend of mine did so in order that her husband's children would be Jewish despite Hitler's best efforts (her MIL lost three out of four grandparents to the Holocaust). They are both atheists, but they still do the various feasts and festivals.
My website is like the majority of websites in that it is a persoanl blog that has no user signups, has no comment section, and has no purchase cart.
I suspect that your website is in the majority in terms of count of websites. However, in terms of unique views, I suspect it is in a tiny proportion. Nearly all the blogs I visit have comment sections.
There are still cases for HTTP only websites (and yours is one of them), but I can't teach my mother to distinguish between when HTTP is safe, and when it is a scam. I *can* teach my mother to avoid a website that Chrome (other browsers are available) labels as "INSECURE". Chrome is going to have a hard time distinguishing between those sites which need to be HTTPS, and those that don't; it's not an unreasonable security trade-off to say "just make them all HTTPS".
You are saying one employee day is worth £150? The usual figure is 200 working days per year, so that's £30,000 / year. Overheads (admin, rent, employer NI, employer pension contributions, etc) is roughly equal to salary, so that an employee being paid £15,000 / year.
For a full time employee (37.5 hours/week), if I have used the calculator correctly, the national minimum wage is about £16,000.
It's going to take several years to recoup the cost (still a decent ROI though).
I have an IoT device - specifically a wood pellet stove which I can control from my phone. Last year I had to upgrade the firmware "because of a change in the certificate". Now, for properly written IoT code (stop laughing at the back there), the firmware will hard code the CA root certificate and the server certificate can be updated as often as required. On the other hand, if you expect to upgrade the firmware every couple of years anyway, it's much easier to hard code the hash of the server cert directly, and just use a long-lived cert. That's not an option if you protect the server with a LetsEncrypt cert that rolls every three months. (On the other other hand, if you are using a hard-coded cert, you can just use a self-signed cert.)
I believe John Lewis do still do Never Knowingly Undersold, but it only applies to high street retailers (and associated websites), not internet only sites (or "internet + showrooms"). has to be for the *same* thing.
Critically though, the price match is for product + warranty (so you can almost never find an equivalent electrical product).
Accounting needs to talk to the vendors, customers, auditors
Finance needs to talk to banks
HR needs to talk to potential employees
Our company (admittedly small, but a datapoint) has no access to fax so a big company which can't do email will just be ignored as a vendor. (We might live with them as a customer, because - money.) Traditional post is a joke, right?
Good end-user training is not a silver bullet, but it does help. Layers of defence internally; internal 2FA; multiple authorization etc help too.
These days most large satellites are dropped into the spacecraft cemetery, they were probably trying for there or thereabouts - but when it didn't break up, it would have landed in a rather different place than the target.
Icon: well it made a bang...
This is not actually true. I picked Omaha, Nebraska - which I happen to know was small enough at the start of the 20th Century that it suffered exactly one casualty in the First World War. (That is about the same as most three-house hamlets in the UK or Germany.)
It is true that *most* of the roads are straight and run due East-West or North-South - but there are plenty of roads that don't run like that. I doubt you can find a single city in the USA that doesn't have at least one curved or diagonal road.
(And of course the problem with city centres is not the odd roads, it's the parked lorries and the children running from their parents.)
Why? The *hope* is that nobody is trying to attack Facebook (or any other company) like this. If this is an attack, *this* attack has failed - but if there is one attack, there will (eventually) be many, and one will eventually succeed.
I'm pretty sure that if the CPU halts it will be rebooted pretty sharpish. Entering a tight loop and not tickling the watchdog sounds much more plausible (and the pilots only have to maintain control until the watchdog reboots the CPU).
I'm still boggled this wasn't caught in unit tests. When I was working with people writing diesel engine controllers 15 years ago, they would have been horrified if this got past unit tests. (And automotive is a lot less fussy than aviation.)
I believe Raspberry Pi's original business plan called for them to build something like 1,000 units. Because Ebon Upton was a Broadcom employee at the time, and because it was a charitable enterprise, he managed to persuade Broadcomm to let him build the Pis. This despite the fact their normal minimum order is probably a hundred times that. Any other startup would have a hard time persuading them to do that.
Of course in the end, it turned out that the business plan was inaccurate by the sort of error that would make a cosmologist blush.
It hasn't been a "British Billion" for 50 years now. My father avoided using "billion" because of the possible confusion, I have always used billion as 10**9 (although aware of the older meaning). I won't see 60 again.
(Icon: because it is contemperaneous with "billion" equalling 10**12.)
Cyprus, 2013. See https://www.reuters.com/article/us-cyprus-banks/idUSKBN1K3242
The two big problems with CVS were:
- Automatic merging didn't work well. Merge technologies have improved dramatically since then, and it is no longer really an issue.
- An individual change was at the file level. There was no multi-file commit. Most systems since then have fixed that.
I have used SourceSafe, Perforce, and git. SourceSafe was unreliable (and didn't have multi-file commits). Perforce was fine, and easy to use. git is fine, and rather more complex to use. I _think_ I prefer git, but that may just be Stockholm syndrome.
Reminds me of a tour I was given of the about-to-be-opened Department of Materials Science and Metallurgy at Cambridge. One of the issues was the safety of the lab for the group which researched semi-conductor materials. Some of the processing chemicals can be ... interesting.
"Never mind" says the architect "we've got a checklist for that. Now then: which processing chemicals do you use?"
Academics: "All of them. And we are in the business of inventing new ones."
Architect: "Ah. That isn't an option on our checklist."
In the end, the lab was put on the top floor with a light roof, so that any explosions could just blow the roof off.
I have. I used to attend lectures of the Cambridge University Astronomical Society. There were (of course) many bad presentations, but there were also some very good ones †. It's really hard to talk about astronomy without showing *either* pretty pictures that your telescope has taken *or* graphs (I tended to prefer the "graphs" lectures, but that's personal taste).
† I have a theory about Professor Martin Rees: if he wants to, he can give a bad lecture. This theory is just like String Theory; intellectually very attractive, but entirely without any experimental evidence.
The Vax 11/780 was *never* competing at this sort of level. The Vax was a significant bump in the performance that a small firm could afford, but it was never a supercomputer
The Cray-1 came out just before the Vax 11/780. The Cray could do about 130 MFlops.
(Conveniently that is almost exactly one tenth the performance of Raspberry Pi model B - but of course a Pi doesn't come with a seat.)
It isn't a belief, it is a geographical fact. See https://what-if.xkcd.com/48/
I think returning the Chagos Islands to Mauritius might end that.
"I'm will to bet it'll be fast tracked".
It may be fast tracked by FAA, but I can't see any of the other aviation regulators being quite so happy to rubber-stamp an FAA approval in future.
Boeing may be able to get it approved by one regulator (eg Europe), and then have the others rubber-stamp that. But that first approval is going to take years.
Well I wouldn't agree with Mr Poolman that *any* wine is wine.
On the other hand, I doubt there are many people who can tell the difference between a £4500 bottle and £260 bottle (I am sure there are some). The big market for £4500 bottles of wine is for people who want to show off how much money they have. And of course, putting them on the menu makes the £260 bottle look positively reasonable (it isn't).
My Samsung S7 had the fingerprint reader on the front. When I lost that and got an S9 I really like the reader on the back. It's exactly where you can put your finger on it when you pick the phone up. I find it much more convenient.
When the phone is on a table, I pick it up and as part of that scan my finger and log in. I have never put my phone in a car holder - I can see it might be less convenient if you do.
20 characters is certainly not enough for any password generated by Diceware (which is the only way i know of generating truly random passwords).
AES-128 is fine though. It can't be brute-forced with computers the size of solar systems running for the current age of the universe. We only need AES-256 if anyone ever gets a quantum computer running with hundreds of qbits. (A quantum algorithm effectively halves the length of the key and something with a 64-bit key _can_ be brute forced by a sufficiently well resourced and motivated attacker.)
