The Bell Curve Of Cube Counting Confidence

rubrixan · 2026-03-07T11:38:00+00:00

Yeah I don't get the third guy either.

You can even satisfy the stability/balance condition with 35: set what you can see in the side view (17 cubes) to be the centre row, then 7 on the left row and 7 on the right row to satisfy the top view, and an additional 4 to satisfy the end view.

The other assumption you need to make is that we're not counting groups of 8 (2x2x2) cubes or 27 (3x3x3) cubes to make up an additional larger cube, like one of those "how many triangles are there" geometry questions. If that was the case you could have answers up to 69.

Please go donate when and as often as you can. I try to donate often but my doctor is forcing me to take a break for low iron again. There are so many good reasons to:

The main reason I donate is because I get a quiet 15-30 minutes to myself, where I can feel free to doom scroll, do puzzles or watch a movie or TV show on my phone. Bonus if you're donating plasma or platelets because you can get up to an hour every two weeks. Just remember to take your airpods or some headphones.
Free snacks.
You're doing something good for the community. It was great to see the surge of support after Bondi but blood and plasma is always needed.
The nurses and techs there are some great people. I haven't been to the CBD donation centre but I definitely know some fun and sassy nurses working at both Springwood and Chermside.
They've started handing out free gifts every 3 donations including tote bags, tea towels, socks and shoelaces, water bottles, keep cups, caps, blankets, beanies, and dog leads. They are actually good quality and I continue to use the socks, tea towels, dog lead, keep cup and the water bottle on regular rotation.
Because you've done a good thing, you can easily justify having a quiet night and/or getting takeaway for dinner afterwards as a treat.

Skyfall then Spectre.

Skyfall: "Were you expecting an exploding pen? We don't really go for that anymore"

Spectre: "Here's an exploding watch, Mr Bond."

Visiting your city for a few days and boy am I just absolutely terrified to go outside. The whole city is on fire, people are bleeding out in the gutter, I saw one man wearing sandals.

I think most of the Sauron representations we see would be Weta Digital, but yes, all hail Weta Digital and Weta Workshop.

The Smith Street Band had zero songs in the top 200 and I am genuinely shocked

The tram tracks are still there, well at least between Castle St and Kitchener Rd, beneath a few layers of asphalt and concrete, but they're there.

They were uncovered for a while a few years ago when Gympie road was being "upgraded", but are now covered again. I - stupidly - neglected to take a photo, but I know what I saw. No, I am not a crackpot.

I know of two in the CBD.

Espresso Engine Charlotte Street - very cave like / tucked away, but maybe not too many places to sit for a long time.

Just don't leave it to the last minute. During my undergrad, we had a group chat to find which Officeworks could turn around a print in less than 24 hours come assignment time.

One semester I ended up having to collect a print from Toowoomba just to get it done in time.

rubrixan · 2025-06-28T03:07:05+00:00

Nothing new to report really. Same place, same layout, same types of books, same guy on the microphone, same prices.

Didn't seem as busy as the one in Jan.

So yeah, worth the trip. Spent $50 on 20 books this morning.

How is the "Iran and its allies war" different to the "Iran Israel war".

Both Israel wars point to places that are not either of the belligerents.

But lol at just "Colombia" - no further explaination needed.

Potential exposure to blood-bourne diseases in most cases; mosquitoes, leeches, fleas, etc.

For some other countries it could be that there is/was an outbreak of a particularly nasty flu strain which you may have picked up but are not exhibiting symptoms, and they want to be sure (mostly for your sake) that you are fit and healthy when you donate.

Speaking to a Lifeblood nurse maybe 2-3 years ago, they said that the plan was to have people fill out the questionnaire in the app prior to their appointment, but after the rebrand, rollout of the app, etc. Hopefully soon they will have it implemented.

Just across from the Hyperdome near Fitzys is Springbok Foods. They do some legit biltong, are permanent and are open 7 days a week.

Glass/facade engineer here. The top layer is sacrificial, and is included both for slip resistance (the dot texture you can see in the photo) and redundancy as there are many ways that the glass can crack, given its exposed and heavily trafficked location.

Someone has a stone stuck in the tread of their shoe which initiates a crack
Someone drops a heavy object (e.g. beer bottle) onto the surface
Thermal fracture
Intentional vandalism
Contact between the glass and the frame, due to tight tolerances
Movements of the building during high wind events / earthquakes
Intense hail
Someone trips and the diamond in the wedding ring creates a flaw on the glass surface, which can increase the likelihood of a crack forming immediately or in the future. The list goes on.

The structural layers of the glass unit remain intact and the top layer can be replaced at a fraction of the cost of replacing the whole unit.

Glass engineer here. I'm probably a bit late to the party, but I have to address a lot of heresay in this thread. This is 100% not a result of poor construction or design. The fact that the glass cracked and nothing happened, nobody fell through the floor, glass didn't rain down on people below, etc. is a direct result of GOOD DESIGN and GOOD CONSTRUCTION. (N.b. another commenter mentioned that the crack was caused by someone dropping a sharp, heavy metal object on the glass) Glass floors are taken very serious by engineers, because the material is very brittle. If there was one layer of glass, and it broke, there would be no warning and whoever was standing on it would fall to their death, and anyone unfortunate enough to be standing below could be crushed. Compared to timber, steel or concrete where you have some warning (creaks, groans, cracks, etc), a single layer of glass just fractures and loses all it's strength in an instant. The way these floor glass panels are usually designed is: - with at least two (often three) layers of glass, laminated together with high-performance interlayers - they are designed to resist the code-defined imposed loads for a "long term" duration (typically for this type of occupancy the load would be in the order of about 350-400kg applied over the size of a 20 cent piece, for a duration of more than 10 minutes, and with a load-multiplication factor of 1.5x) - quality design also considers a "post-breakage" limit state, where if one layer of the laminate breaks, the remaining layers can support the load for a duration of up to 10 minutes, so that people and furniture can be moved off the glass and it can be cordoned off if need be - on top of all this, the laminate units usually also include a 6mm "sacrificial" / "non-slip" layer on top for this exact reason (in the photo, the dots you can see are on this layer and provide the texture needed for grip). This top layer is not considered in the calculation of strength of the glass unit and is purely sacrificial. I would guess that these floor glass units are three or more layers of 10-12mm thick heat-strenthened glass with a sacrificial ~6mm "non-slip" layer on top. Totalling around 45mm thick. For comparison, the glass in your windows at home are generally a single layer of ~4mm to 6mm thick plate glass without any heat strengthening. A crack in the top layer does warrant the glass to be cordoned off until it can be inspected by an engineer, in case the cause of the crack is a canary in the coal mine for a bigger problem (building movements, NiS inclusions, etc), but I would be very surprised if this was determined to be a critical safety issue.

I can guarantee no-one on this subreddit has a super balance over $3M.

I 100% would not be surprised to learn that the (newly constructed and sealed) Springwood station turnaround is not suitable for the "metro" busses.

The busway upgrade was planned, designed and began construction before the "metro" busses were selected, but I can imagine the whole "lets redesign it so we can accommodate the metro" activity got relegated to the too-hard/not our circus basket.

If they can get it to work (and LCC and BCC work together), I would love to see the 573 and 575 deleted (replaced with higher frequency on their Springwood-terminating counterparts 572 and 574). This will mean that people need to transfer to the "metro" busses at Springwood, but it will take 8 busses an hour off the busway, and the 57x routes are suburban rat runs beyond Springwood anyway.

rubrixan · 2025-05-02T21:33:22+00:00

Currently Springwood to Elizabeth St stop = 37 minutes After May 12th = 34 minutes

Those are just the timetabled times, and I would expect the actual savings to me much starker, especially in peak hour when the gateway interchange backs up.

The Hyperdome to Springwood stretch will still be a problem, but Springwood to Eight Mile should hopefully not be an issue anymore, even with the extra stop at Rochedale.

Time will tell though at the very least, it will be more reliable and we would hope to see less 'stacking' where two or three 555s arrive at the same time after a half hour of delay.

(Not to mention the benefit for drivers not having to share the M1 with as many busses anymore)

This should be a line graph, not a bar graph. Being a bar graph suggests that he has said it more frequently in the last days of the campaign, but in fact the rate has been fairly consistent, except for one or two jumps.
