I've been playing a bit of Minecraft this weekend and noticed much worse raytracing performance than previously. After a bit of investigation it looks like a regression was introduced with 1.16.220 which has substantially reduced performance, dropping from around 90+fps to 30ish, this is on an RTX 3080 with DLSS turned on at 3440x1440.
After a bit of troubleshooting it looks like its related to v-sync, changing:
Seems to fix the issue and brings performance back to a more reasonable level. If you do want to re-enable v-sync you can force it with the nVidia control panel without the issue being re-introduced.
In 2020 CityFibre started digging up parts of Worthing to install Fibre to the Premises (FTTP), they sell this wholesale to ISPs, similar to BT Openreach. Their network allows for gigabit-ish speeds. The main difference for consumers however is CityFibre offer a symmetrical connection for residential and not just business customers, so around 900Mbps down and up. In comparison BT Openreach FTTP residential packages offer around 900Mbps down and 100Mbps up.
The UK's long obsession with asymmetrical lines with crippled upload speeds is coming to the end. In the age of people uploading to YouTube and other services, upload speed is important, its always been important and its a shame we've had to endure poor upload speeds for so long.
In Worthing at least, only TalkTalk and Zen are using CityFibre's network at the moment. Not willing to go anywhere near TalkTalk, Zen was the natural choice and offers a static IPv4 address (noice). Zen sell this as their "Full Fibre 900 Plus" package, for £40 a month, offering an unlimited connection up to 900Mbps up and down. As this is only offered in a handful of locations at the moment this usually won't show up in their normal web pages, if you know you have CityFibre in your area you can use CityFibre's website to go find the right page to order from.
We ordered in the 1st week of April, and by the 2nd week we had the install completed, this involved digging up some brickwork across our front garden and running the line into the house, this took the engineers about 2 hours to complete and they've left the area looking how it was when they started.
On the exterior they've placed their CityFibre box, shown here next to a Virgin cable install:
On the inside we have the fibre coming through the wall and running to CityFibre's Optical Network Terminator, from what I gather all installs with CityFibre lines at the moment are using a separate ONT and not a combined router and ONT. The Virgin DOCSIS line we have is running through the middle of the photo and under the carpet:
Zen then supplied us with a Fritz!box 7530 router. This is actually a pretty full-featured router, it offers far more features than I can possibly go into here, and makes BT and Virgin's supplied routers look like fisher price toys in terms of functionality.
Speed wise, these were conducted early on a Friday evening:
Latency typically 6 to 7ms to most UK sites, a marked improvement from Virgin's cable services. Similar to what you see on BT's FTTP lines. 100MB/s+ from Steam was nice to see. It's probably safe to assume realistic speeds are probably 700-800Mbps and up* at peak times, but it can be difficult to gauge as many of the online speed tests may have other bottlenecks somewhere when we start approaching speeds this high.
*Obviously don't expect these speeds on WiFi.
I've not noticed any traffic shaping, random websites being blocked or ports being blocked or any other weirdness in the first few days. If I note any reliability issues, I'll update this post below any questions, feel free to leave them in the comments and I'll answer if I can.
Google's, Netflix's and thinkbroadband's test results are below to give you an idea of speeds you'd likely expect:
I've recently been porting a fairly substantial website over to a static generator from a CMS, I've wanted to maintain a commenting system on it however as it is still fairly active. So I decided to use Remark42 as its self-hosted and pretty powerful, plus still under development. One of the areas not well documented was running it on Apache without a subdomain.
I figured it would be easier to run it under a folder, and not have to worry about getting Let's Encrypt through a proxy for SSL renewals.
This guide assumes you've already got Remark42 successfully up and running on http://localhost:8080 or however you've configured it.
We're going to be installing it onto a website called example.org and running a proxy through a folder called comments. Remark42 is configured to run with the below:
In one of Apache's config files (it may not be called httpd.conf), we basically needed to add the location and the proxy addresses to the existing site configuration, a lot of other config has been removed in the below example, but the important parts are between the two location tags:
That's actually enough to get it up and running, I do have mod_proxy installed in Apache. Take careful note of trailing slashes, they are important!
However the out-of-the-box /web/ does break, it references files from example.org/web/ rather than example.org/comments/web/ this only seems to effect the demo webpage however showing the behaviour below:
In a simple test page however:
This is working, with the only changes to the documentation being specifying the host and site_id.
host: "https://www.example.org/comments", // hostname of remark server, same as REMARK_URL in backend config, e.g. "https://demo.remark42.com"
It's possible there is something else that should be configured to make the demo site work properly, but frankly it doesn't matter.
I also have not tested it extensively in a cross-domain setup, but I would likely run separate instances of Remark42 on different ports to achieve that. Now if only I could customise that date format.
After traveling since July 2020, the new Perseverance rover has successfully landed on Mars. Hopefully it'll go on to be as successful as Pathfinder's Sojourner rover, Spirit, Opportunity and the still active Curiosity.
Only low-resolution images from its engineering cameras have been transmitted back, but they're enough to confirm its safely on the surface.
After twenty four years Adobe Flash today reached end-of-life, and the product is no longer supported. If you're using Microsoft Edge, Google Chrome or most other browsers, their respective developers have already released updates that disabled it.
However if Adobe Flash has been installed manually, or pre-installed by your PC manufacturer its possible you'll get this prompt appear:
It's probably worth checking in Settings -> Apps and seaching in there for Adobe Flash and uninstalling it.
Adobe Flash was pretty popular back in the olden days, being installed on most computers connected on the internet, being required to handle animations, and media playback on the web.
But it was also a common source of exploits and vulnerabilities - and annoyance for end-users with its constant pop-ups and required installs, this was remedied a bit later with browser manufacturers building in the plug-in in out of the box (and distributing updates), but with the development of HTML5 video and WebGL it essentially became unnecessary for most users.
Back in November my aging i7 6700K system built back in 2016 PC got updated, the new system is built around:
AMD Ryzen 9 5900X CPU
Asus ROG Strix B550-F motherboard
Crucial Ballistix MAX 32GB DDR 4000 RAM*
Artic Liquid Freezer II 280 CPU All-in-One watercooler
MSI GeForce RTX 3080 GAMING X TRIO
NZXT H710 case
NZXT C850 PSU
It used my existing Sabrent 2TB NVME drive.
*this was purchased prior to general availability and before difficulty in overclocking the FCLK became apparent.
Review: It is fast, and now plays Minecraft with raytracing enabled, well enough (for now).
