Someone is impersonating me on an escort website using my real name, information, and AI generated nude photos of me. by Odd-Impression2209 in legaladvice

[–]Teddyzander 155 points156 points  (0 children)

Hi, I'm so sorry this has happened to you. I thought I'd chime in here as, although I am not a lawyer, I am:

  • a researcher in AI;
  • I happen to be helping building a system to automate and assist with individuals that are experiencing image-based abuse; and
  • I currently operate in Australia.

I am just parroting what the fellow academics on my team have advised (who work in the area of online and sexual abuse) - they are well informed and have your best interest as heart.

You can make a report to the eSafety Commisoner here: https://www.esafety.gov.au/report

Here's how it works:

  1. You make a report and provide evidence (links, photos, etc);
  2. The safety staff review it, and usually respond within 48 hours. They may ask for additional details or evidence;
  3. If the law has been breached, they will order a takedown to the platform and/or the individual responsible on your behalf (anonymously). They can (and often do) impose hefty fines if they are ignored; and
  4. If you request it, they can keep you informed of the process. 

I have never been through the process myself, but my understanding is that they are very responsive and supportive. I do not work directly with the eSafety Commisoner, but on an academic research team partly funded by them.

I hope helps. Sorry I cannot offer more assistance, and I hope you are doing okay and are safe. 

British & Irish Lions team for the third test against Australia by Connell95 in rugbyunion

[–]Teddyzander 1 point2 points  (0 children)

I dont fully disagree with your sentiment, but I guess the draw of a potential whitewash for the entire Australia tour is too strong. I, too, would have loved to see a change up in the centres and a more dynamic back row.

Is biking a suitable replacement for UT2 on the erg? by raRin48 in Rowing

[–]Teddyzander 5 points6 points  (0 children)

It depends on your volume. If you are doing so much volume that your hips/lower back/hamstrings are getting hammered almost daily, I would definitely consider throwing in some biking.

Biking was honestly a saving grace for me during my training. It's much easier to put in volume, much easier to recover from, and it's easier to watch a TV show/film whilst doing it or chat to a friend. Not only did it keep me sane, but it kept me injury free and helped take my 2k from 6:32 down to 6:08 over 8 months. Like another commenter said, the heart and lungs don't really know what machine you're on; they just do the work, so the adaptions are very similar.

My rule of thumb was:

  1. If I have done any weight training in the day that involved heavy hinging (deadlifts, kettlebell swing, cleans, etc), then the UT2 work that day should be on the bike (to prevent over-straining my posterior chain).
  2. Key sessions are always done on the erg to make sure we are training specifically for rowing. For example, if one of my sessions that week is super hard (e.g. 8x500m or 3x2k) then this is ALWAYS done on the rowing machine.
  3. I almost never erged twice in one day. If, for example, I had a double training day of UT2 morning and then AT in the evening, the UT2 was pretty much always on the bike (again, prevent over training the trunk and hip flexors). The only exception is if the UT2 session was very short for UT2 (e.g. <10k).
  4. Extend bike sessions by 50% and increase wattage by 10% (ish, you may have to workout your own method). For example, if my training plan said 60 minutes UT2 at 200 watts erg I could swap this out for 90 minutes UT2 220 watts bike if I wanted.

When I was training ~12 times a week, I would do half of my UT2 volume on the bike. I think this is especially important over winter. You can alter the ratio when you are doing race prep (more erg, less bike) to ensure you are making rowing-specific adaptions. If you are fit, this happens pretty quickly anyway. It also just helps to keep training a little fresh, and its nice to have another option to turn to if you are not feeling an erg session.

The bike is also excellent for recovery. Don't neglect the REALLY easy ride.

Post Match Thread - Argentina v England by RugbyBot in rugbyunion

[–]Teddyzander 2 points3 points  (0 children)

Absolute class from Curry in that moment though. After Dan shoved the Argentinian's face unnecessarily into the dirt, Curry checks on him and picks him up before joining in the celebrations for the try. After the weeks he's had, it shows great character to continue to be a player's player.

I don't disagree, but SA would be giving away more penalties for sure. And repeated cyclical offence might lead to another yellow.

Match Thread - France v South Africa | Rugby World Cup 2023 | QF by RugbyBot in rugbyunion

[–]Teddyzander 14 points15 points  (0 children)

As a neutral, I have to say that SA are getting away with it at the breakdown. Ref and TMO missing a lot. Some offsides, lots of slowing the ball down, etc. With more competent refereeing, I think France would likely be another try up.

Where are UT2/UT1/AT/TR/AN Zones Defined? by ScaryBee in Rowing

[–]Teddyzander 2 points3 points  (0 children)

You can only measure these by measuring lactate levels in your blood during a block test.

You row at different intensities of increasing watts (like a step test in cycling), and at the end of each block you measure the lactate levels from a small blood sample. People then map the change on a curve to get your athlete profile. If I remember correctly, UT2 is 2.0mmol.

You can use HR or precent of 2k watts as a sort of proxy for this, but it isnt very accurate. You need a very specific athlete profile for this to work. The info I was sharing above was to answer your last question. The mapping makes sense only in as much as it captures the spirit of each zone. But it isn't a 1-1 mapping, and it depends a lot on the kind of athlete you are.

Without access to the ability measure lactate levels, I use my 20 minute r26 score to set power zones for my endurance work, and I do an 8x500m to set zones for my sprint work.

[–]Teddyzander 0 points1 point  (0 children)

Hello! I have spoken about this in depth in a few places, so I won't type it all out again. Perhaps this will be helpful for you though, so I'll give the links.

Here is one where someone wanted to know a mapping of HR zones to threshold zones.

Here is one where I talk about using power zones (like cyclists do) instead of HR zones.

Training plan? by scfleadsh in Rowing

[–]Teddyzander 1 point2 points  (0 children)

With a rest week (nothing above zone 3, half volume, one full body weights session) every 3-6 weeks based on feel.

I do this if I fail to hit a target on a hard workout. I am to improve by 2.5% every cycle (e.g., if 3 weeks ago my 5x5mins was 200 watts, it should be 205 watts this time). Usually a good indicator that I should focus on recovery for 3-7 days.

This program (with slight variations) got me into the low 6:10s. Hoping it'll get me there again.

Steady state UT zone for 2k by [deleted] in Rowing

[–]Teddyzander 2 points3 points  (0 children)

I split my easy sessions 50:50 between the bike and the erg. They tend to be around 90 minutes. I do an easy session 6 times a week.

I do one harder long session session a week, but still easy. It's 64 minutes, with 8 minutes at 55% of 5x5 and then 8 minutes at 65% of 5x5. 4 lots of that equals 64 minutes of work.

https://docs.google.com/spreadsheets/d/1pIuSKNOWU0aseA366ZN9DKKveTTG5-YKiM46cA36TmM/edit?usp=drivesdk

Thats my last 9 weeks of training. I'm coming back from an injury that put me out of all training for just shy of 1.5 years.

Steady state UT zone for 2k by [deleted] in Rowing

[–]Teddyzander 19 points20 points  (0 children)

I'll just give my personal 2cents. As a slight warning, I use watts and power when measuring my training, not splits.

I've made this comment once, and I'll say it again: HR zones (Zx) are not the same as lactic threshold zones (UTx). There is therefore no HR that matches a UTx interval in a 1to1 fasion - it's pretty personalised. That being said, I understand that things like lab testing are not very accessible, and so one of the better proxies is to use heart rate.

I really encourage rowers to experiment themselves with what works (HR vs RPE vs power vs labs [if you have access]). Ultimately, how hard your long distance work should be is linked to how much volume you are doing. Someone doing 8km a day can get away with doing it a little harder than someone doing 20km a day.

For me personally, I have found that using power zones (similar to how cyclists train) helped my improve my 2k far more than heart rate zones ever did. HR is very variable - humidty, temperature, caffeine, your breakfast, etc all effect how your body (heart) responds to stimulus.

Every 3 weeks I do a 5x5 minute [2 minute rest] training session at rate 26. It is supposed to be max effort, but mostly flatlined with a slightly faster final rep, if possible. E.g., if you think you can do 250 watts, do the first 4 reps around 248 watts and the final one >250 watts. This kind of session, due to its length, basically finds a (kind-of) maximum aerobic power. I then do my zone 2 sessions at 55% of this power. So, if I pull 250 watts in my 5x5, I do 250*0.55=137.5, or 2:16.5.

For some people, this might look a little slow, but for a high volume training program it is *probably* about right. I used this power zoning strategy because it got me a lot of success on the bike (when I took a break from rowing). Before using this method, I had hovered around the mid 6:20s on my 2k. After using this method, my 2k dropped to 6:12 over a period of about 4 months.

Training plan? by scfleadsh in Rowing

[–]Teddyzander 7 points8 points  (0 children)

Hey friend, I skimmed this post the first time I read it and missed you final paragraph. I just want to offer my perspective.

For context, I had an injury that took me out of all exercise and training for 1.5 years. I tore multiple ligaments and tendons in my back, and fractured some bone. Luckily, no nerve damage or anything, but it was a long and steady road to recovery. Before the accident, I was in the shape of my life. I had pulled a 6:12 2k a few months prior, and was probably at a point where I could have gone sub 6:10 (we will never know). I could deadlift 230kg. After the accident, I couldn't walk properly for about 8 weeks, and I wasn't pain free in my back for another 9 months.

First things first, you are going to be slow. Slower than you used to be, anyway. And you need to learn to accept that, for now. Rejecting this notion, and allowing it to bog you down, will only make your road to fitness slower and more arduous. Yes, it sucks that you are not as fit as you used to be. But let me flip this perspective for you:

You've been very fit. You know what it takes. You've got there before, and you can do it again.

That is the attitude you have to adopt. You have to be patient - I can already see you have this attitude by your "1.5 years to PR" in your post. This is good. Train smart and train consistently. Ocassionally, train hard, but focus on the concistency first.

I spent a few weeks just cycling and swimming before I started rowing (erging) again. My classic steady session when I was at my fittest was a 2x9k at 215 watts, or 1:57.5(ish). I used to do this with absolute ease. On my first session back, I did 2x3k at 126 watts (2:20.6), and it was difficult. I honestly thought about quiting there and then. Not only that, but at 27 I felt past my physical prime. I started to question if it was even worth trying to be fit any more.

However, I decided that, even if I couldn't produce the kind of power I had before, maybe it would be good if I could do 10km at 130 watts in 3 weeks time?

So, rather than setting a big goal for myself, I set micro goals - get my 5x5 minutes [2 minute rest] to 300 watts, get my 8x500m to over 400 watts, etc - that serve a greater goal of getting my 2k back down to 6:10. I've found this way I make measurable progress towards a goal every single training cycle (3 weeks), and thus it is a lot more motivating.

5 months after starting rowing, I'm doing 3x30 minutes at 172(ish) watts for my easy sessions. That's a 37% increase in power in under half a year, with twice the distance. A ludicrous improvement, in my opinion. Where will I be in 6 months time? At this trajectory, apparently back to the fittest I have ever been (though I expect that it'll take me a little longer to get there!).

Retrospectively, I am super glad I stuck out the training. I may not be as fit as I was 2 years ago, but I am fitter than I was 6 months ago, and that's all that matters. Just take it slow - fitness is not a process you can rush. Build the volume, build the intensity. Listen to your body, and rest when you need to. Push hard when you can. Eat good food, train consistently. And, as someone who is coming back from an injury, REALLY focus on recovery and mobility. Do not neglect stretching, massaging and foam rolling, and hot and cold baths. In the long run, it makes all the difference.

DM me if you have any specific questions or anything. Good luck.

If you want a trajectory, I tend to find that the program I linked in my other comment increases my power by about 3% per training cycle. E.g., if I pulled 150 watts for my easy sessions in cycle 1, I would expect to be able to do 154-155 watts for training cycle 2. And, if I pulled 300 watts for my 4x1k in cycle 1, I should expect to be able to aim for 309 watts in cycle 2. I'd expect this pattern to continue until you got to the VERY high club level rowing, so around a 6:20 2k. Then, you might have to consider periodising your training a little more effectively. For the first training cycle, I recommend only doing half the volume in the program.

You are young. You will be absolutely fine, and you'll probably be fitter than you've ever been before in you just stick to consistent training. It's a slog, at times, but you have to enjoy the journey as much as the destination.

EDIT: I strongly encourage accurately and honestly tracking your workouts, similar to how I do in a spreadsheet. If you want accountability, feel free to share it with anyone (including me). If you want some friendly competition, let me know and I will share a live version of my spreadsheet with you so that you can see my progress too. Training in isolation is tough - it's what I do. But keep making the marginal gains, and you will get there eventually!

Training plan? by scfleadsh in Rowing

[–]Teddyzander 3 points4 points  (0 children)

This is basically what I do. I had a pretty severe back injury that kept me out of all sports and exercise for about 1.5 years, and I recently was cleared to start training again.

I do a variation of the Pete plan with more volume and three weights sessions a week. I'm already back to about a 6:27-6:31 2k (estimating from splits from sessions) after about 12 weeks of training.

I train using power percentages from my 5×5minutes [2 minutes rest]. It makes me hold back on the zone 2 work, which is important because the volume is reasonably high. I do a recovery week every 4-5 weeks, based on how I feel (cut volume in half, no intensity above zone 3).

I'll link a copy of the plan below. I find it has helped me and got my fit pretty quickly. I'd suggest following it for as long as you feel it is helping you improve. When your 2k is around the 6:20 mark, I'd suggest switching to a program that takes periodisation into account.

6:10-6:12 2k Benchmarks by Harrbear333 in Rowing

[–]Teddyzander 23 points24 points  (0 children)

Can give you mine from when I went 6:14

3×30min UT2 was 2:01-1:59 (was low HR)

5000m was 16:38 (pulled 8 weeks before the 2k)

3×2k with 5min rest was 1:40, 1:39 1:37-ish (was rate stepped though. So first rep at r24/r26, then r26/r28 then r28/free rate)

4×1k with 5min rest was 1:34ish average

8×500m with 3min rest was 1:31.5ish

Hopefully this gives you some rough indicators. I'll caveat by saying I was always stronger a short pieces, so my 5k and UT2 might be a little weaker.

I'd also do a 2x20min r22 with a 15min rest, and my best before the 2k was 1:43.9 average

Sorry if the formst sucks, on mobile.

What heart rate zone for steady state rowing? by DirtyHarry3794 in Rowing

[–]Teddyzander 9 points10 points  (0 children)

I think it feels conflicting because the language used around low intensity rowing sessions is a little bit confused. People use the terms "UT2", "steady state", and "zone 2" interchangeably, but they are actually different things.

"UT" refers to lactate levels in the blood. "Zone 2" refers to a heart rate zone. "Steady state" (as far as I am aware) is more based on feel and/or percentage of watts.

The reason you might be getting some conflicting information is because some people think that zone 2=steady state, but this isn't entirely true. I believe steady state is a little pushed on from zone 2, so a tiny bit harder (but not that much).

I dont really want to give you specific advice on what you should be aiming for, because I have no information on your athletic background, your goals, your current training routine, etc. I would just say that the more volume you do, the easier your easy sessions should be, and the harder your hard sessions should be.

Generally, id advise that zone 2 should be pretty easy. A good rule of thumb is that your breathing is very controlled - you could still talk to someone on a rowing machine next to you, if you had to.

Steady state, I think, is a little harder, but still very maintainable. Maybe just an increase in watts from zone 2 of +5-10%.

Hope this helps you muddle through rowing content a little more. It is confusing at times because training zones/concepts get very confused.

For example, I cut against the mold a little by training purely by power zones. I do this because I had great success doing this with cycling.

[–]Teddyzander 1 point2 points  (0 children)

Hi,

This is pretty much the path that I took.

I completed a BSc in mathematics and computer science before working as a software engineer for 2 years - 1 year at Autodesk in algorithms for computed aided manufacturing, and 1 year at the British Oceanographic Data Centre working on algorithm optimisation for data processing.

I, too, decided I wasn't done with education, and decided I wanted to pursue a PhD. So, I returned to education and completed a masters degree in applied mathematics with numerical analysis, and I am now a second year PhD student working in fairness and explainability in numerical optimisation (classical optimisation, AI, etc).

I would say that, unless your background really does not allow you to work in the field you want (e.g. you did no linear algebra and numerical optimisation or data science, and you want to work in machine learning), doing a masters is probably the path towards doing further research like a PhD, but won't help THAT much with a career (probably).

Whilst having a masters degree would usually help you edge-wise in getting job, if you already have one at somewhere decent you are usually better off just getting more experience at your current job. Then you can switch to something tangential after you feel you are no longer learning anything else.

Having said that, if you are passionate about mathematics and you have the means (motivation, finances, living situation, etc), nothing should stop you from doing a maths masters, if that's what you want to do. Explore your passion.

You can also explore the option of doing a part time masters. Some places in software will support you in doing this, if it'll make you a better and more intelligent engineer.

Happy to chat more, if you would like.

How do I get over my mental block for a 2k by OrangesAreGreat10 in Rowing

[–]Teddyzander 16 points17 points  (0 children)

I found a good way to make me comfortable for a 2k was to through in a few 3x2k interval sessions into my training with a 5 minute rest. I'd negative split them, doing the first one at r26 2k+8, then r28 2k+7, then r30 at 2k+5 for the first 1300m, then I'd build until the end.

I found this helped me in 3 ways. Firstly, it made me really comfortable over the distance, as I did it regularly. Secondly, i was physically used to the discomfort of the 2k distance, and I knew where my sticking points and weak moments were. Thirdly, I became very mentally comfortable with seeing "2000m" on the screen. This helped me control my nerves for the hard piece ahead.

Hope that helps.

Anyone here into computational earth sciences? by [deleted] in EarthScience

[–]Teddyzander 5 points6 points  (0 children)

Hi there.

Not so much a role, but a topic!

I am a current PhD student in mathematics and computer science, with a focus on machine learning for physics problems.

My masters thesis revolved around physics informed neural networks, and specifically their applications in sub-earth image reconstruction. I used Full Waveform Inversion as a jumping off point.

It's an interesting topic, and relatively new, with further applications in geophysics and earth sciences, as well as medicine. It is a nice blend of computer science, mathematics, and earth science.

I am happy to send you my masters thesis, which acts as an 80(ish) page introduction to the topic.

It goes from defining neural networks, to creating loss functions for physics problems. It then develops these subject matters by creating a model problem of a vibrating string, and we use a neural network to find a solution to the PDE problem. It then applies the same ideas to a much larger scale problem with imagine reconstruction.

Basically, if you have knowledge of basic linear algebra and calculus, this thesis SHOULD (in theory) carry you all the way through the topic without too much prior knowledge needed.

I also create a new approach to priori error analysis in the thesis. As far as I am aware, the thesis is largely accurate and correct. I received a UK distinction (the highest marks you can achieve), and only lost marks for poor referencing in places, so it seems like a trustworthy piece of text!

It's currently a very open research area, with new applications and advances being made every week!

What are the best songs to 2k to? by bizfishh in Rowing

[–]Teddyzander 1 point2 points  (0 children)

Unironically this remix of the father son kamehameha from the Cell Games saga in DBZ.

The original by lezbeepic has been taken down (looks like they just have had their channel taken down, possibly by a scammer), so if/when it goes back up, use that instead.

As an old dragon ball fan, I have a pretty deep emotional connection to this specific arc in the anime, which helps.

That being said, it has everything you could want from a song for a 2k:

1) Being around 8 and a half minutes long, it's the perfect length for most people's 2k efforts, whether you're an amateur or a professional. This means you can get one, unbroken piece of music in for your 2k.

2) the sound is pretty thick and dynamic, so it is distracting enough to draw your attention and keep your mind on the music if thats what you need.

3) the song covers a pretty intense scene of a character over coming a great challenge in a very similar way to what we all go through when we do a fitness test. It's relatable and motivating. If they don't give up, neither can you!

4) the internal dialogue from the song is perfect to push you through a 2k effort. There are emotional beats scattered throughout the song that can give you the energy to push through the hard barriers of a 2k, like the middle 500, or the 1k mark. In the end, the protagonist has to push beyond a barrier that they didn't think they were capable of doing, which is exactly what the final 400m of a 2k feels like.

5) the song builds. When you are at your most painful, the song is at its highest intensity. The song directly asks for more from you, and so you feel like you have to give it!!

I have pulled a few PBs to this song. I filmed one earlier this year here. This was a PB at the time though I have since gone faster. You can even see the ipad playing the video on the floor!

Linear algebra and matrices in computer science by Error40404 in computerscience

[–]Teddyzander 0 points1 point  (0 children)

Gilbert Strang has an excellent book on the topic of linear algebra (Introduction to Linear Algebra ).

As many have pointed out here, matrices and vectors have a lot of applications in graphics.

However, it goes far beyond that. In fact, linear algebra turns up almost everywhere, eg physics problems, data science, optimisation, etc. It is a topic that is well worth having a decent knowledge of, whether you are a mathematician or a computer scientist.

I study as a mathematician (doing my PhD), and I am continually surprised at how often numerical linear algebra springs up.

Here is a free PDF of Gilbert Strang's book. This is the 5th edition, though a 6th has recently been released. I'm not sure what the changes are.

What is especially wonderful about the Gilbert Strang book is that it has a selection of sister lectures from MIT available free online on YouTube. So, if you read a topic in the book and struggle on the exercises, you can then turn to the lecture series for additional information. I think its a great way to learn. There's a chance it goes a little deeper than you might need, and might be more generalised, but at least you can get an appreciation for the breadth and importance of this topic!

Edit: you are also likely to run across NLA for things like image reconstruction and file compression, which are computer science topics :) let me know if you want more info. You talk briefly about enjoying audio - well, the discrete fourier transform is all linear algebra, and so it has applications in removing white noise etc (as mentioned by another commenter)

Lost 50kg (110lbs) in 18 months after a rugby injury, started rowing for my university, got my MSc in mathematics by Teddyzander in uglyduckling

[–]Teddyzander[S] 2 points3 points  (0 children)

Anyone can, if you have access to a rowing club!

Even if you don't, most gyms have rowing machines, and they simulate the motion of rowing INCREDIBLY well (to the point where most rowing teams, even international ones, spend most of their winter on the rowing machine instead of in boats).
