DEADBUG

"The term "Deadbugs" is an industry nickname for the discrete components added and wired into a printed wiring assembly (PWA) to facilitate active circuit modifications, rather than redesign and manufacture a new board. The nickname comes from their general appearance on the board: upside down, with their termination leads (legs) up in the air - like a dead bug."

10 of my plants have fucking THRIPS and I am about to go away for a WEEK on vacation: a short horror story

[adolin]

do you have any tips/resources for a beginner who wants to get into weightlifting?

thank you for asking!! I love this question. I love lifting! It's Good For You (helps increase bone density & metabolic rate, and it's good for injury prevention and developing functional strength). It's also a really great confidence boost. 10/10 would rec lifting to every single person reading this — if it's an option for you, give it a try.

TLDR: familarise yourself with common exercises. pick a beginner program. follow it. profit!

A more involved answer, with resources and details, is under the cut

familiarise yourself with common exercises

There are hundreds of possible exercises out there to target each specific body part. However, most of those are what's called "accessory" movements, as opposed to "basic" exercises that will pop up over and over in most lifting routines. Ideally, you want to know how to perform these movements, using light weights or just your bodyweight until you feel comfortable with it.

CORE BRACING (ft deadbugs. genuinely lifechanging skill!)

Squats.

Hip hinge. This is useful for deadlifts, romanian deadlifts, kettlebell swings & similar movements

Push movements (for example: dumbell chest press, shoulder press etc)

Pull movements (dumbell rows & many others)

That said. Please don't stress too much over "good form". Each exercise has infinite variations and especially as a beginner, you won't be lifting heavy enough weights to make form optimisation a big concern. All bodies are different and our individual stances vary a lot depending on body proportions, flexibility levels etc. You just want to know HOW an exercise is supposed to be performed, in terms of: which muscles it activates? what am I supposed to get out of it? how to do it safely? Your bodyweight squat doesn't have to be flawless, it just has to be good enough.

BTW, you know when I said that there are hundreds of possible exercises out there? Here is a very detailed masterlist + exercise guide for exercises impacting each muscle group.

learn your way around a weight room, if you aren't familiar with it already.

Broadly speaking: the free weights (bar, dumbells, kettlebells) are good for compound exercises that involve multiple muscle groups. The various machines are ideal for "isolation" exercises that target fewer specific muscle groups.

If you already know what's what, then skip this bit! But I've talked to many people who feel a bit intimidated by the weight room because they feel out of place in it, and in my experience familiarising yourself with the general layout is a good way to take away that discomfort.

And, in case this is something you need to hear: you deserve to be there, you're not taking space, and most gymgoers just want to finish their workout and shower, and won't pay specific negative attention to you. Most gyms have a weight room manager or floor trainer, at least during some shifts, and they WILL be happy to help you. If you're someone who doesn't want to be bothered while exercising, just preventively introduce yourself, say you're new

pick a program

I highkey recommend following a pre-made program instead of just fucking about on your own. Here's why

programs are well-balanced in terms of volume and muscle groups, to ensure you don't overtrain one body part and leave other lagging

they have a built-in "progression scheme" that will allow you to move to a higher weight in an optimal way — basically, you'll see strength advantages sooner

they help navigate information overload. There is SO much information about fitness out there that acts as an entry barrier. Following a pre-made program really helps with that.

If you have a gym membership, you may have the option of one "free workout program" made by a trainer who works at the gym. If that's in the cards, I'd recommend going with that.

Otherwise, I strongly recommend the "programs rec guide" over at r/xxfitness, the female fitness subreddit (the name is 15 years old but it's a queer friendly, trans inclusive space). I haven't personally done any of those, but Meg Gallagher of Before the Barbell is very solid, and that's the one I'd suggest.

get ready for DOMS

Also known as delayed onset muscle soreness. It happens 1) when you go to the gym after a while or start exercising for the first time 2) when you train a different muscle group than usual 3) when you up the intensity of a workout.

Basically, you wake up in the morning and you go OUCH!! ACHEY. That's DOMS. It happens because your muscle fibres are suffering microtears and reknitting (stronker!!) and you will feel very stiff and possibly very swollen (muscles retain water).

It'll take a few days for it to go away. IT IS SAFE TO EXERCISE THROUGH DOMS; the only thing limiting you is if you're too achy to move effectively. I recommend eating something protein heavy (more on that below) and doing some gentle exercise to make it go away faster (walking, at home-stretches or yoga, swimming if it's an option, etc.)

You DON'T want to stay in bed the whole time, because that'll only make you more stiff and make it last longer. Note that "post exercise achiness" is something that WILL go away after the first couple of weeks or so, depending on your recovery (again, gentle exercise and/or going to the gym again when you're still a bit achey is actually preferred than being completely at rest until they're fully gone away). Long term, you're NOT supposed to feel high-level soreness after working out. "No pain no gain" is mostly bullshit.

evaluate your program!

I'm always saying this, but the best exercise is the one you actually stick with. If your exercise plan is dull or fills you with dread, it doesn't matter how good for you it supposedly is — ditch it. Give yourself a few weeks of whatever program you pick, then re-evaluate: what are your favourite exercises you've done so far? Which ones you don't like? What would you like to do? Programs can and should be modified according to your preferences, and it's a lot easier to customise something that works for YOU once you're a bit more familiar with everything. For example, maybe someone at your gym is doing kettlebell swings and you think it's cool and you'd rather do those instead of crunches for your abs. Why not. Just note down what's working and what isn't, and then re-evaluate (with gym trainers if that's an option, but also, I mean it, HMU whenever).

odds and ends!!

None of these things are a big deal, but they make your life easier:

Hydrate during a workout. If you're hydrated your body works better. You'll also probably sweat during your workout. Getting through 1L of water during a 1 hour / 1 hour and a half gym session is perfectly normal.

Warm up before lifting. Something like this for a general body warmup + lighter warm-up series before going up to the weight you actually want to lift. For example: if you're squatting the bar (20kg) I'd do one bodyweight squats series, and another series holding a 10kg kettlebell or dumbell. Cool down or stretch after!

Mobility work on a day off is a good idea, even if you're no longer suffering through soreness. This is my current go-to routine, I do it about 2x week.

If possible, eat protein the evening / day after a workout. Protein is great for building muscle, and you WILL see a noticeable difference in energy level and speed of recovery by upping your protein intake. Basically: if you usually eat lentils or fish twice a week, try to make one of those times your post-gym dinner.

(In general, as a beginner you WILL see results regardless, and you don't need to optimise nutrition or anything (not to mention, it can be overwhelming / complicated to deal with.) But if you're interested in the specifics of nutrition & exercise, HMU)

keep track of your workouts! I really recommend this; it can be very inspiring to have a backlog you can look at when you want to track your progress, and you want to establish a benchmark with yourself. It can be as simple as writing down gym days & numbers in your journal if you have one; personally I use the Strong app to save my routines, and every week when I log in new workouts I modify the values depending on what weight and # of reps I hit that week. For reference, this is what a week looks like on the Strong app for me

As I've mentioned before, the ultimate goal for my 68030 homebrew systems is to run a proper multi-user operating system. Some flavor of System V or BSD or Linux. I am not there yet. There is still so much I need to learn about programming in general and the intricacies of bringing up one of those systems, plus my hardware does not yet have the ability to support multiple users.

I've toyed with several ideas as to how to get the hardware to support multiple users, but ultimately decided to leverage what I have already. I have a fully-functional modular card-based system. I can easily build new cards to add the functionally I need. And to make development and debugging easier, I can make each card simple, dedicated to a single function.

The catch is I've already run into some stability issues putting everything on the main CPU bus. So what I really need is some kind of buffered peripheral bus I can use for developing the new I/O cards I'll need.

So that's where I started — a new 8-bit I/O bus card that properly buffers the data and address signals, breaks out some handy I/O select signals, and generates the appropriate bus cycle acknowledge signal with selectable wait states.

It wasn't without its problems of course. I made a few mistakes with the wait state generator and had to bodge a few signals.

With my new expansion bus apparently working I could set out on what I had really come here for — a quad serial port card.

I have it in my head that I would really like to run up to eight user terminals on this system. Two of these cards would get me to that point, but four is a good place to start.

I forgot to include the necessary UART clock in the schematic before laying out the board, so I had to deadbug one. I'm on a roll already with this project, I can tell.

So I get it all wired up, I fire up BASIC, attach a terminal to the first serial port, and get to testing.

Nothing comes across.

Step-by-step with the oscilloscope and logic analyzer, I verify my I/O select from the expansion bus card is working, the I/O block select on the UART card is working, the individual UART selects are working. I can even see the transmitted serial data coming out of the UART chip and through the RS-232 level shifter.

But nothing is showing up in the terminal.

I've got the terminal set for 9600bps, I've got my UART configured for 9600bps, but nothing comes across.

I did note something strange on the oscilloscope though. I could fairly easily lock onto the signal coming out of my new serial card, but the received data from the terminal wasn't showing up right. The received data just seemed so much faster than it should be.

Or maybe my card was slower than it should be.

Looking at the time division markings on the oscilloscope, it looked like each bit transmitted was around ... 1.25ms. Huh. 9600bps should be more like 0.1ms. This looks something more like 800bps.

I set the terminal for 800bps and got something, but it wasn't anything coherent, it was just garbage. I wrote a quick BASIC program to sweep through the UART baud rate generator's clock divider setting and output a string of number 5 for each setting until I got a string of 5s displaying on the terminal.

So then I tried sending "HELLORLD".

I got back "IEMMOSME".

No matter what I changed, I couldn't get anything more coherent than that. It was at least the right number of characters, and some of them were even right. It's just that some of them were ... off ... by one.

A quick review of the ASCII chart confirmed the problem.

'H' is hex 0x48, but 'I' is 0x49. 'E' is 0x45, but was coming across correctly.

... I have a stuck bit.

The lowest-order bit on my expansion bus is stuck high. That's why I wasn't seeing any coherent data on the terminal, and it also explains why I had to go hunting for a non-standard baud rate. The baud rate generator uses a 16-bit divisor to divide the input clock to the baud rate. When I tried to set the divisor to 0x0018 for 9600bps, it was getting set to 0x0118 — a difference of 256.

Another quick BASIC program to output the ASCII chart confirmed this was indeed the problem.

Each printed character was doubled, and every other one was missing.

That sounds like it could be a solder bridge. The UART chip has its D0 pin right beside a power input pin. A quick probe with the multimeter ruled that out.

Perhaps the oscilloscope would provide some insight.

The oscilloscope just raised more questions.

Not just D0, but actually several data bus pins would immediately shoot up to +5V as soon as the expansion bus card was selected. As far as the scope was concerned, it was an immediate transition from low to high (it looked no different even at the smallest timescale my scope can handle). If the UART was latching its input data within the first third of that waveform then it certainly could have seen a logic 1, but it doesn't make sense why only the one data pin would be reading high.

I thought maybe it could just be a bad bus transceiver. The 74HCT245 I had installed was old and a little slow for the job anyway, so I swapped it out for a newer & much faster 74ACT245.

And nothing changed.

It's possible the problem could be related to the expansion bus being left floating between accesses. I tacked on a resistor network to pull the bus down to ground when not active.

And nothing changed.

Well ... almost nothing.

This was right about the time that I noticed that while I was still getting the odd waveform on the scope, the output from the terminal was correct. It was no longer acting like I had a stuck bit and I was getting every letter.

Until I removed the scope probe.

Too much stray capacitance, maybe? That waveform does certainly look like a capacitor discharge curve.

I had used a ribbon cable I had laying around to for my expansion bus. It was long enough to support a few cards, but certainly not excessively so (not for these speeds at least). It was worth trying though. I swapped out the ribbon cable for one that was just barely long enough to connect the two cars.

And finally it worked.

Not only was I able to print the entire ASCII set, I could program the baud rate generator to any value I wanted and it worked as expected.

That was a weird one, and I'm still not sure what exactly happened. But I'm glad to have it working now. With my hardware confirmed working I can focus on software for it.

I've started writing a crude multi-user operating system of sorts. It's just enough to support cooperative multitasking for multiple terminals running BASIC simultaneously. It may not be System V or BSD or Linux, but I still think it would be pretty darn cool to have a line of terminals all wired up to this one machine, each running their own instance of BASIC.

Monday 21st October

Windy walk this morning after a terrible night's sleep. We went out just before 6am, got back just before 7 and I really considered going back to bed for a nap but tbh the wind had woken me up enough that I had a decent stretch and some core work:

Deadbug 3x24

Squat > standing crunch 3x20

Double leg lifts slow 2x16

Plank hip dips altnernating 2x20

Mountain climbers x32 > 1 min plank

This was my view while doing leg lifts. Coach maggie right there in my personal space with her stinky sardine breath

Had a slice of pumpkin loaf for breakfast! It's tasty! Good with butter 👌

Worked from home, washed our sofas to send photos to the charity that are coming to collect them on Saturday. Pumpkin soup for dinner, bath, bed. I am so tired my dudes I really hope we sleep better tonight bc all 3 of us were wide awake at 2am last night for no good reason. Bonus sleepy Mags after I accidentally woke her from her post-walk nap because I dared to get up from my desk to pee
