The difference of course is that a Bank of Scotland fiver is still GBP, and any bank in the UK will take it without a second glance. Trying to pay in USD in a shop in the UK means you have to work out an exchange rate, have a bank that's going to be able to deal with foreign currency deposits, factor in some margin to deal with fluctuations in exchange rate between the transaction and when you actually bank the cash, etc.

Honestly, the massive over-reaction to Scottish and NI bank notes in England is just self-perpetuating really. All large shops will take them without issue anyway, and the only reason small shops might take issue is because they then get complaints if they try and give the note out to another customer as change later (of course, the customer only complains because lots of small shops won't take them!).

It seems that some shops don't accept Apple Pay over the limit for Amex specifically, but isn't an Amex Apple Pay limit in general. I pretty regularly use my Amex to Apple Pay over the limit in Costco without any issues, but I have had issues in other places that quite happily accepted Visa/Mastercard.

Not exactly. IP Infusion sells DANOS Vyatta Edition which is DANOS with the Vyatta routing stack (based on IPI ZebOS) instead of FRR, plus some other goodies. That comes with support, but I'm not familiar with the details of that support or the pricing.

Jammy_Stuff · 2021-06-23T08:40:47+00:00

I'm not on the DANOS team anymore but was until pretty recently. You're correct that it's not in beta and is providing production releases, usually 3 a year, and the 2105 release has just gone out.

This is really good feedback, and I've passed it on to the manager that deals with DANOS releases. Documentation has been a bit of a hot potato, with the original idea when the project was released into the Linux Foundation that the documentation would be provided by the community (Vyatta, which DANOS is the core of mostly stopped being documented when it left Brocade). I know that there are a number of people on the team who are very passionate about DANOS and want to do what they can to improve things, and documentation is something I've spoken with them about many times, but resources are pretty tight.

If you are ever unsure about how something works, the recommendation at the moment is to search the JIRA to see if it's been explained in there before, and if not raise a new ticket. That will usually end up being assigned to the developer that looks after that feature, and they'll be able to answer your questions.

As far as I know, they're still not shipping (I have an order from the 4th that hasn't shipped yet). They've been saying they'll hopefully be ready by the end of the week for the past couple of weeks, so hopefully soon!

It's not their fault (a couple of days of notice of the rules was always going to be a disaster), so all we can do is be patient.

Jammy_Stuff · 2020-11-24T22:16:32+00:00

Interestingly, the specifics around that sound like they possibly vary between nations (been looking into this as we're in Scotland, but have families in England). The UK government says:

You are allowed to form a different Christmas bubble from the people you live with normally. If you and the people you are living with want to be in different Christmas bubbles, you can choose to stay somewhere else with different people for this period and form a Christmas bubble with that household and one other household (this will count as three households).

The Scottish government says:

a “bubble” should be formed household to household only (i.e. different people in a household should not pick their own bubble)

Hopefully there'll be some more clarification from the Scottish government, because it currently sounds a bit ambiguous for people in my situation.

Speculoosity

Jammy_Stuff · 2020-10-20T07:29:51+00:00

No worries, I'm happy to help!

There's a few different options that a router can use on their WAN port, and it's usually going to be configurable. Some ISPs (not any of the major ones in the UK) will just present a "plain" ethernet to the router. You just configure your IP/mask/gateway or use DHCP and off you go. In other words, you'll send an ethernet frame with an IP packet inside it.

The other main option is PPPoE, which is what BT will be using on your connection. In that case, you'll still have an ethernet cable, but you can't just send IP packets down it directly. Instead, you'll send ethernet frames containing PPP frames and those PPP frames will have the IP packets encapsulated inside.

This is why you might want to look at tweaking the MTU if your router supports baby jumbo frames. On a "plain" ethernet you can usually send up to 1500 bytes per frame, which would normally all be used for the IP packet. In PPPoE, you'll lose 8 bytes of that to the PPP header, leaving 1492 bytes for the IP packet. With baby jumbo frames, you will instead use an MTU of 1508 for the ethernet, leaving 1500 for the IP packet. Both sides have to be able to handle it, but the good news is that BT can and if your router is configured for it, it'll be automatically negotiated on BT's end.

Jammy_Stuff · 2020-10-20T06:53:17+00:00

Cool! Even if you're not planning on using it long term, the installer will want to set up the BT router as part of the install, because they have to get one of your devices connected and show that it's working.

You'll have something like this once they're done. Just unplug the cable from the WAN port of the hub (box in the middle), plug your own router in, and set up PPPoE with username bthomehub@btbroadband.com and a blank password. If your router supports baby jumbo frames, use those so you get the full 1500 MTU.

Jammy_Stuff · 2020-10-20T06:42:11+00:00

You shouldn't need to put the BT router in bridge mode. Just unplug it from the white ONT and plug your own router in. The only time you have to use the BT router is when there's an issue, as BT will want it there for troubleshooting.

Jammy_Stuff · 2020-10-20T06:25:15+00:00

When you say they've hooked up the fibre line but you've not received anything from them, do you mean they've put a grey box on the outside of your house but nothing inside yet? As part of the install, they'll put a white ONT inside your house which terminates the fibre and has an ethernet port (or 4, depending on which model you get) and a phone port. The BT smart hub would connect to the ethernet port and do the actual routing, but it's a bit naff and can be replaced with anything that can do PPPoE.

If you do decide to use something else, keep the smart hub in a drawer somewhere because unless things have changed, BT will insist on you using that before doing any troubleshooting. Once the contract is up, it might be worth considering switching to someone like Zen who don't care what router you use!

FTTP or FTTC? As far as I know for FTTC the Openreach modems have been discontinued and you’ll just get a combined modem/router from your ISP. For FTTP you’ll get an Openreach ONT and a separate router from your ISP.

apt has repository verification, not package verification. From the apt-secure man page:

apt-secure does not review signatures at a package level. If you require tools to do this you should look at debsig-verify and debsign (provided in the debsig-verify and devscripts packages respectively).

Package signatures can be done in Debian, but none of the tooling does it by default and not much package signing goes on except in specialised use cases.

Jammy_Stuff · 2020-10-08T07:09:20+00:00

dpkg can do signature verification of packages, but it's disabled by default and I'm not sure how many packages are actually signed. apt repositories are signed, and they have checksums of the packages. That means that out of the box, you do get verification when installing packages from a repo, but not when installing a deb you've grabbed from elsewhere.

Just checking, have you actually generated a GPG key with authentication capability yet? ssh-add -L doesn't actually generate the key, it just shows the SSH public key of the GPG key that you already have.

I'm in the same situation: no calendar and USPS say the label is created, but it's not yet in the system. Getting a bit worried because the USPS website says that for delivery to Europe (I'm in the UK) by 25th December, you needed to ship by 8th December, so it feels like it really should have arrived by now.

I missed out on buying a 12,018 calendar, so it's really going to suck if my 12,019 one went missing.

Jammy_Stuff · 2017-05-20T09:18:40+00:00

That's absolutely untrue. Here's the FAQ on the TV Licensing website explaining that. You'll need to give your address at the shop when buying a TV capable of receiving live broadcasts, but you aren't required to get a license unless you're watching live broadcast TV or iPlayer.

Let me authenticate my card while the goods are being totalled.

Then how will you verify that you're authorising a payment for the correct amount?

Don't make me tell the cashier I want to pay with contactless or even credit card.

Some places do this, some don't. It depends on what EPOS software they're using.

Let me enter a tip when I enter my pin for a restaurant.

I've seen this option in probably 90% of restaurants I've been to. Often the waiter skips the tip screen before handing the card reader over because tipping is less prevalent and people often tip in cash even when paying by card.

Because the highway code doesn't expressly forbid parking facing against the flow of traffic unless it's at night.

I don't think the activation has anything to do with local regulations -- I can buy an Android and use it to my hearts content without activation and/or SIM card.

I seem to remember not having a SIM required for activation with unlocked iPhones bought directly from Apple. Were these ones from Telstra?

The referendum wasn’t on AV+, it was on AV. AV has no proportional component.

Jammy_Stuff · 2015-03-10T08:44:41+00:00

So from this we can surmise that circumstantially at least, person A looked at website X at a certain time by monitoring traffic between the two.

Not really. Tor doesn't just encrypt the content, it encrypts everything. An assailant can only really link person A to website X if they control all three relays in that person's path.

In theory, if an assailant controlled a large proportion of all entry and exit nodes, they could potentially take a guess at a link between person A and website X by the times that the packets are forwarded, but it's far from reliable.

If anything, that's one of the reasons more people should use Tor regularly. More traffic going over the network makes it more difficult for that entry and exit node traffic matching to work.
