The write-up for my pseudo-3D renderer (used in the ZX Spectrum game, Cosmic Payback) is now up on the web: https://t.co/3Bn3TdLQL7

@codexeditor @ZX48kSpectrum Most ZX81 programs can only use the top and bottom borders for running code - the text takes up the rest of the screen. Since the space in-between the text, stars and 3D view is blank, I can use that for running code too, giving us twice the processing time of other ZX81 games

[PROSM @ZXPROSM]

@PaulTunney @ZX48kSpectrum Yes, an embarrassing mistake on my part - I had that menu in place for two months before the release, and still never noticed it!

It's patched in the V1.1 release from April (on https://t.co/qWJYfW8kUH), which also fixes a bug with the stars on ZX81s with more than 16K of RAM.

@Sharopolis I've sent you a reply from my personal email address - just letting you know in case it ends up in your spam folder :)

[PROSM @ZXPROSM]

@Sharopolis Thanks for messaging me here too, and sorry for the delay - turns out my email program had lost the settings to log in on my ConnoSoft address - I get barely any emails on it anyway so never noticed that it was broken! I'll get my reply to you later today

Now that app-based authentication is far more common, let's talk about a major sin Google is doing:

They ONLY recommend using Google authenticator.

Google authenticator is one of the worst apps to use: you lose your phone, and you've lost your auth codes.

Use eg Authy instead.

If you’ve ever harboured ambitions to make your own game this is a wonderfully low-stakes friendly and fun “competition” where the games are *supposed* to be a bit crap (or very crap, or absurd, or even good maybe!) #CSSCGC #zxspectrum

[PROSM @ZXPROSM]

@M_Gordon_29 @23pauljs @BBCRosAtkins No worries :)

@23pauljs @M_Gordon_29 @BBCRosAtkins I think Euronews made a typo yesterday - it is now reporting that the quote was "fixed penalty notices", as is Reuters and France24, amongst others - https://t.co/g9O3HSz7LC

Isn't it great, installing all sorts of packages in a vain attempt to get Ubuntu to detect your laptop battery, then you find out that the only reason it didn't work was because it had slipped out slightly and the pins weren't making contact :(

@fesshole I went for a job at the Oxford English Dictionary. I've got a mate who works there, he said he'd put in a word for me.

A little progress with BBC BASIC on the Master System - loading and saving files via a serial port, some crude graphics support and a partial SOUND/ENVELOPE implementation. Impractical but fun! https://t.co/gakdlQw5Mb

Sealed games are selling for absurd prices.
Hmmm...imagine how much they would go for if you already opened them before you sold them! That's a premium service and saves them a job.

@PoliticsForAlI @guardian I've no idea why Manchester University seems to be involved in some bizarre game of reputational self-immolation, but I feel very sorry for the students who have been taken for a £9k-a-year ride by these fools.

@JAMOGRAD Or you could just print the instructions on the inlay ;)
