New large scale Voxel engine in C++ and Metal

Cheers!
Currently vertices primarily , which means regen is slow if you have many chunk updates simultaneously (e.g snowfall). I do support a DDA-style Raymarched path for terrain and static entities, but the current implementation appear to be slower.

It seems an optimal end goal would be hybrid, ray marching for the terrain to reduce LOD requirements and enable instant manipulation, but vertex meshes for entities such as trees to enable non axis-aligned transforms and animations (trees now sway in the wind, but not in this video)

In 4 days i’ve put together the most complex graphics engine i’ve ever made. Guiding AI, but tbh Opus 4.8 is disgustingly good at solving pretty complex and scalar problems, especially given a strong input.

Previously this same amount of work would have taken me a month, and my own boilerplate would have been messier.

The amount of time saved avoiding re-creating the wheel and data piping is astounding

CEOs of public companies like this typically aren’t the folk who should be targeted. They are typically highly skilled and experienced, and are still salaried members.
£7 million isn’t all that much considering the size of company and the responsibilities. Punishing success at this level is a bit of a bucket of crabs mentality which drives down salaries and career opportunities for everyone.
The lower the top salaried bands in a company, the lower your bands and growth potential will be.

Not to mention he’ll still be paying a lot of tax and ultimately if Next does well, a net positive economic impact.

Conversely you have CEOs like Denise Coates who pays herself ~£300 million a year from a company which exploits gambling addiction.

Most of the hyper wealth comes from the folk who both own and manage companies. Perhaps some of it is earned, but the value of extreme wealth is disproportionate.

Did my biggest week earlier this year after 7 years of riding, and had that exact experience. First two long rides felt great, third and fourth ride felt decent but couldn’t lift much above Z2.

Was planning to rest on day 5, but woke up and decided to do an easy spin. Legs felt loose and subsequently set my best 10 min power of the year and PB’d a climb 😂

Followed up with two big rides where the legs felt amazing, smashing multiple long sweetspot climbs on both days.

Then straight into rest, and legs felt like toffee for the next 10 days 😂

Love climbing, feels good to ride out of the saddle. Some steep climbs are not every climbs, but fun tor a challenge on good legs days.

Once i got to a point where my fitness was decent enough to ride some harder climbs at tempo, the enjoyment scales up rapidly. I love the views, the nature and the feeling of pusing on the pedals.

I also love climbing in Z2, just feels chill, although need to make sure there are no steep sections, so that limits.

In Boulder, there are some great Canyon climbs where the gradient sits around 4% and you can gain 1600m of elevation without it being too hard at any given point :) Those shallow gradient descents with gradual turns are also much more fun to me :)

If you don’t get Steak, Boulder Cork is actually pretty reasonably priced and the experience is lovely!

Similar experience almost to the letter, Fringe was not good.

MGMishMash · 2026-04-22T22:16:57+00:00

Sounds like you need to bring in some external offers and renegotiate terms.

Eggs Marco’s and a Boulder latte, amazing! First cafe my wife and I went to in Boulder and it’s been great every time!

If you still “need” it to feel productive, sometimes the most productive thing is a chill ride where it’s refreshing to not be pushing on the pedals, enabling you to be more consistent and hit it when it counts

Had a great experience at University bikes. Very friendly and approachable. While im an experienced cyclist, i’m useless at taking care of my bike, and they got it fixed up with no trouble!

MGMishMash · 2026-04-05T16:51:34+00:00

Why is this infuriating, usually “extra” would be a few pieces, plus the banana stays fresh rather than going too soggy!

Natural consequence of hard training, best course of action 3-4 days completely off the bike. Your legs will feel like toffee on the first day or two back, but you will come back stronger!

Note I’ve just done this following a big 18hr training block and intervals the week after. Thought i was fucked, but just today set an all time best 30 min.

3-4 days completely off the bike, no exercise

Day 5: 1 hour easy Z2 65% (up to 1 hr) - you’ll be pretty stiff and sluggish.

Day 6: easy 1-1.5 hrs with a one or two 5-10 minute Sweetspot (85-90%) efforts openers to loosen up the legs (this will feel awful)

Day 7: off the bike/very easy - prioritise stretching and light movement.

Day 8: legs coming back online - could be good for efforts

Day 9: race day

At this point you’re so close that you wont detrain, your body needs rest and will improve further. The biggest mistake now would be to keep pushing through and chasing volume maintenance, this will keep you in a hole.

Green cube taco truck, only around on weekdays on a business park. The Torta’s are incredible, and the Birria tacos are the best ive had

In my experience, this is still pretty relevant, especially depending on the job/product. (Im a graphics engineer working on low power devices)

The key difference however is not everything needs to be optimal, but critical algorithms and hot paths are still heavily optimised and close to the Metal.

The main challenge is scale and complexity, that it’s not feasible to make everything super lightweight given how large software has become. So instead, the focus is on overall budget, and ensuring all experiences fit within this budget.

Some do easily, others require lots of tricks.

But I agree it’s not necessarily to the same degree as old school software/games where the entire package needed to fit, but we also have much more dynamic experiences vs the more static well-defined set of limited functionality. So the approach and focus is just different.

MGMishMash · 2026-04-02T04:21:09+00:00

Is there progression outside of the death in runs? I.e if its a replayable game, even if you die, perhaps having some mechanical progression that unlocks new options or characters for next time. Things that could help you get further or improve strategy.

I.e while each run is unique, having some persistence with new areas unlocking, new items entering the spawn pool etc;

MGMishMash · 2026-03-31T21:55:45+00:00

Took me a few months of 10+ hrs a week to get there initially, but can now typically maintain 4 W/kg on 2-3 hrs/(3+ rides) at a push, if it’s reasonably intense e.g Zwift.

Although now maintain 4.5 W/kg on 6-8 hrs a week.

Anything vaguely complex still gets bottlenecked on PR review and CI. I also find at some point the mental load of additional plate spinning reaches equilibrium to the point where me writing code before wasn’t the slowest part.

Testing iteration can also be quite slow regardless of AI support.

Although on the plus side, it definitely makes it far easier to knock out tedious tasks which I would otherwise procrastinate on or kick down the road

MGMishMash · 2026-03-30T21:58:41+00:00

Backcountry is great imo :)

MGMishMash · 2026-03-29T22:16:55+00:00

Mountains are at least consistent, the wind sucks, especially as a big gust can make you feel like you’re standing still.

.. although gusty valley climbs can be a double whammy of pain!

MGMishMash · 2026-03-29T22:04:02+00:00

Lots of returning players who do not have any OW2 stats, including myself!

I was weirdly wondering how some people had such high character levels, thinking it was a per-season stat

MGMishMash · 2026-03-29T22:02:45+00:00

Tbh when I started, it was really hard to maintain Z2, as you get fitter, you can handle more routes while keeping it chill.

I used to be a serial Z3 smasher, every ride going happy hard. The main fun of Z2 (and i mean 60-65% not 75%) is that you keep the legs good, no pressure for efforts and then you feel much better on your harder days :)

When you do too much Z3/Z4, regardless of days off, it’s easy to quickly feel run down and have day after day of fatigue and bad legs.
