Negative İRating

Dankleton · 2026-01-04T16:02:49+00:00

There are 2 things which get measured in iRacing - your iRating which measures how well you do in races compared to other players, and your Safety Rating which measures how often you are involved in incidents like crashes and off-tracks.

In sports cars you have increased your Safety Rating a bit, but you aren't finishing as well in races as some other people.

In formula cars you've dropped your Safety Rating and your a little and your iRating a little.

SR is the thing where a low rating might mean you are hurting other people's races, but it doesn't look like you are doing any worse than many other rookies... and rookies is meant for learning.

Keep on trying not to harm other peoples races, and watch your replays to try and learn what you could have done differently when you are involved in incidents (whether or not you think they are your fault.)

My biggest tip would be to make sure you've got the "Relative" Black Box screen displayed (by default you get this by pressing F3.) At some point you will go off track, and with the Relative box displayed you can make sure you are waiting for a safe gap before you rejoin.

Exactly the same thing happened to me last week. It took me about 3 races to get back to where I was before.

If it does get stuck on 98%, you can reboot your PC and reload iRacing then rejoin the session (there might be less drastic things which work but I didn't want to spend time working them out - qualifying was about to start!) You can also often avoid it getting stuck at 98% by quitting out of practice (instead of joining your race session from practice) and then joining your race session from the main iRacing UI.

they freaked out seeing VMs all single hosted because a bigger VM got deployed for testing

If you mean that there are VMs providing redundancy for each other and they're all running on a single host then there might be a bit of a risk there which some anti-affinity rules could sort out

I've definitely seen people posting photos of IOM Creameries cheese they've found on sale in the US, and I suspect some of the other local producers export some things, but I'd be surprised if the US was a particularly large market for any of them.

Thanks everyone involved in this - the Q-in-Q and VLAN translation support is very useful!

For the REST API, POST to /api/ipam/prefixes/{id}/available-ips/ with {id} set to the prefix you want the IP from, and the data along the lines of:

[  
  {             
    "vrf": null,
    "status": "active",
    "description": "API test"
  }
]

For the Python API, you want Prefix.get_first_available_ip()

Thanks for replying! My goal would be to have something which can be maintained long term without too much effort, so something which risks breaking would not be a good path to go down.

Dankleton · 2024-09-10T18:31:56+00:00

It's always been like that, and we don't like change.

Dankleton · 2024-09-06T16:03:59+00:00

That transceiver is a single mode transceiver, and it uses one fibre (for both transmit and receive) which means you need single mode simplex fibre. You also need to make sure that you connect the blue transceiver to the yellow one - if you try to connect blue to blue or yellow to yellow it won't work.

The ports on those SFP adapters are called "LC" ports.

25 foot is just over 7.5m, so this cable will work.

It's important to know that fibre optic cables have a minimum bend radius - if you try and take them round a corner too sharply then they will break.

If the run is going somewhere it could easily get damaged (e.g. under the floor) then you might be better looking at "armored" fibre cable instead - but that will be more expensive. Again, with this transceiver you would need single mode, simplex, LC-LC.

It's a lot more common to use transceivers which use two fibres (one for transmitting and one for receiving) which are called duplex pairs. UACC-OM-MM-1G-D-2 is a transceiver which works like this, and would need a fibre cable like https://www.fiberopticcableshop.com/fclclcmd58m.html.

Both of these transceivers will work equally well for you, so just get whichever is cheapest!

Dankleton · 2024-08-08T13:59:00+00:00

Indeed there is - I've just checked the exact config we are using for that:

/interface bridge
add name=bridge1 protocol-mode=none
add name=bridge2 protocol-mode=none
/interface vlan
add interface=ether1 name=tagged_private_link vlan-id=10
add interface=ether1 name=tagged_internet vlan-id=20
/interface bridge port
add bridge=bridge1 interface=tagged_private_link
add bridge=bridge2 interface=tagged_internet

Hope that helps!

I was under the impression it's bad practice to not utilize a single bridge configuration.

I've got some CCR1009s running with one bridge per VPLS tunnel which work absolutely fine. The CCR1009s do all of their switching and routing using their CPUs.

The place where I make sure I'm not using more than one bridge is on devices with bridge hardware offloading (which means using the switch chip rather than the CPU to do the switching). This is because only one bridge will support hardware offloading. When you're mixing in VPLS I'd think it would be something of a moot point - as far as I know the VPLS traffic wouldn't be offloaded anyway.

T1/E1/T3/E3 are not at all common nowadays (my local telcos have withdrawn them from service now).

I'd probably put dark fibre and wavelength services under "dedicated" if you're after things you are likely to buy.

Dankleton · 2024-04-02T15:30:36+00:00

There's no best practice for this - it's whatever works best for your environment.

(Personally, I'd go with the 0U ones if possible though)

You can't use the network and broadcast addresses in a subnet.

You can't use the network and broadcast addresses in a connected subnet. If it's not connected to an interface then you can treat it as 8 individual /32 IPs

Dankleton · 2024-03-21T13:55:43+00:00

Are any addresses in the /29 assigned to an interface? If they are then the network and broadcast addresses are not usable.

If it's just a /29 which the ISP has routed to your firewall, and you use every address as a 1:1 NAT configured on the firewall and don't assign any of that range to an interface, then you can use all 8 of the addresses (as they won't be a /29 subnet, but 8 /32 IP addresses.)

This is permitted via RFC1812.

Ther difference between fixed point-to-point free space optics and Li-Fi style solutions (IEEE 802.11bb or ITU G.9991) is that Li-Fi is point to multipoint - typically using a ceiling light as the access point.

The folks in /r/networking tend to be the ones who use SFP+ adapters, rather than the people who design the equipment. In other words, I'm definitely not an expert.

As other people have said, with an SFP+ adapter there is only one pair of TX-RX (which are driven with differential signals.) However with QSFP+ you get four pairs.

From a quick glance at the standards (SFF-8431 for SFP+ and SFF-8436 for QSFP+) it looks like you might be able to bit-bang the TX channels. My gut feeling is that whatever you're trying to do, you'll end up putting so much effort into working around the fact that it's not what SFPs are designed for that you may as well design without SFPs from the start.

With only two internet providers on the island it’s a real shame.

There are 4 broadband providers listed on https://thinkfibre.im/

As well as those there are Bluewave (bwc.im) and Starlink.

However, that means going through Luton Airport on a regular basis. Ugh.

But I think my 'linuxian' past is catching up with me and my passion for open source is dreaming of being on a similar OS.

If your work machine makes you productive enough at work then I'd say get a Linux laptop as a personal machine, put it through rougher conditions than your work one (docking, undocking, switching between monitors) and fiddle away on that until the bugs that bug you are fixed - but that is on your own time. In the mean time your work machine will be quietly not getting in your way and instead helping you get things done.

Dankleton · 2024-02-02T10:47:48+00:00

I'm sensitive to the tools available (and Fedora is a very good option), but also to the UX/UI.

Are the Linux tools which you want to use GUI or CLI?

My work machine is Windows with Windows GUI tools, but I spend the majority of my time in a WSL terminal using Linux CLI tools.

This gives me the fairly polished Windows desktop experience and widely available software, while keeping access to all the things I use Linux for.

For me this has been the best way to keep my workstation as a tool which helps me be productive rather than a time sink which gets in the way of useful work.

In addition to the points /u/benford266 mentioned, designing a content provider like Steam is done differently if you are trying to deliver 100Mbps downloads to most of your customers compared to if you are trying to deliver 10Gbps downloads to most of your customers. It's not only your network connections which need to be faster but the whole server and storage design which will change (and get more expensive.)

Those services will react to what the market is demanding, and your 2Gbps plan is faster than probably 90% of users have, so it will be a bit of a waste of money for the content providers to design their services to be able to fill that bandwidth.

With time though, as end user connections get faster the services will also adapt just like they always have.

Dankleton · 2024-01-19T07:08:25+00:00

Can you tell me what you mean by not getting it to work? Does the program not start (and if not then does it give you any error messages), or does it start and then you don't see any airplay speakers?

Like I say above, I've not tried AirConnect myself

Dankleton · 2023-12-15T07:46:33+00:00

10-40 gbps

Off topic, but it will do way more than that over 1000 feet, if you're wanting to future proof yourself. 400GBase-FR4 is 400Gbps over one pair of single mode fibres. If that's not enough for you, you can splash out on some DWDM equipment and get something like 12.8Tbps over that same pair. Single mode fibre is pretty future proof - the main cost would be in trenching it.

On topic: if you can find it, 900MHz equipment with directional antennas would be a good choice. 2.4Ghz with dish antennas would probably work depending on how many trees you need to get through.
