I remember this case well I was a teenager at the time and it shocked the whole town as violent crimes like that didn't happen in Redditch let alone violent murders. I remember seeing him on the news with West Mercia Police appealing for witnesses and describing how he cradled her as she was dying. The guy exhibited all the signs of a classic psychopath. Showing no sign of any real emotional responses or empathy. Just flat emotionless matter of fact. It was an explosion of anger and hatred. A very frenzied and sustained attack with 57 stab wounds as I recall which suggests a guy with an intense hatred of women or a warped sexuality that requires violence. Since he stalked her he most likely had an abnormal twisted sexual arousal that requires inflicting extreme violence and murdering. Quite a daring attack in daylight in middle of car park given he must have been covered in blood and couldn't have hoped to flee the scene. I remember the knife was recovered. He'd thrown it over the carpark down onto a building roof and think the police got a finger print on it. He ended up in Broadmoor a secure prison facility for the criminally insane didn't he? Never to be released where he belongs. The other frenzied murder we had in Redditch was Tracey Andrews who stabbed her boyfriend to death. The same as Stuart Hopkins appeared on TV at first and was not initially considered a suspect by police until later on. I remember seeing Andrews a lot around the Kingfisher Shopping Centre before the murder. She's out of prison now and even had cosmetic surgery in prison. Way back in late 19th century was the very first murder (and only murder of a police officer) very close to Redditch at Icknield Street a stones throw from St Leonards (Beoley) Church. PC John Davis was stabbed to death by a man stealing sheep in the early hours of the morning who was later caught and hanged for it. It happened very close to the cross roads between Beoley village and Redditch along Icknield Street leading to Wythall is said to be haunted by the ghost of PC John Davis. There's a few sightings of him with his unusual 1880's police uniform which one driver mistook for fancy dress custom when stopping to offering him a lift only for him to vanish. PC John Davies grave is at St Leonard's Church, Beoley and his original Constable badge and a memorial display is inside the church which itself is rather creepy. I always felt a presence in there as a young lad.

Enjoying your videos, we’re doing a similar itinerary next summer but swapping Alicante for Cagliari. We sailed on Britannia this year but to Norway, we really liked Britannia. We ate in the dining rooms which were included in the cruise and a few extra cost restaurants. The buffet was always heaving so we gave it a miss.
@Bangford
@Bangford Месяц назад
Thank you so much Sarah! That's a good swap. The castle in Alicante was great, but the walk from the ship to the beach wasn't good (some discarded bottles etc, bit of a mess). It was the only place we visited that felt like that. We discovered the dining room breakfast on the penultimate morning and realised we'd made a mistake going to the buffet every day. Enjoyed the Beach Hut and Sindhu too. Hope you have a great cruise next summer :-))

Santa Barbara Castle is incredible and I still get the heebigeebies at the shot of the sea from the top of the castle because I know there are these sheer walls with a sloping bit at the top. There's another incredible castle a few km in from Benidorm, Castillo de Guadalest, it's got it's own museum of torture. Also, there is the Fonts de l'Algar, a waterfall, made famous for the Timotei shampoo advert. Fantastic cruise you've had, almost tempting me to take one hehe 😊
@Bangford
@Bangford 2 месяца назад
The thought of those sheer walls is giving me the heebigeebies now! It's funny, I was much more worried about being in the long tunnel waiting 15 minutes or so for the lift! They really love their castles and cannons round there don't they. Thanks for the info, I would love to check out the waterfall. Thanks for watching. The cruise was a great adventure, we got to see a lot of different places in a short time. It was good knowing that you could go back to the same cabin every night and not have to find new places to stay. Cheers, Toby.

That's really interesting! I had some concerns about it before we left. I was worried it would be difficult to sleep if it was moving around too much. That was fine, but the room felt slightly claustrophobic and it was weird knowing that you couldn't go anywhere other than on the (giant) ship. As I have an insurance background, I tend to assume the worst and thought the ship was "probably" going to sink at some point. When we got back, I found out that the same ship was caught in a storm in Majorca last August, broke free and hit an oil tanker. So glad I didn't know that before!!!

@Bangford
@Bangford 3 месяца назад
Yes, I've built models in R before, using GLMs, XGBOOST and neural nets. Also built a basic neural net in R, following a tutorial. I really enjoy data science work (used to manage an insurance pricing team in London). The main reason for switching to Python is to make use of CUDA, because it can do maths on the GPU. I would really like to figure out how to make Mandelbrot plots using the GPU as they're 50 times faster! The best tutorials assume you want to make large language models, so I'm going along with that for now :-))

Thank you so much, I really appreciate it! Your comment on the last video really helped me to understand the 100 prisoners problem.
@RSLT
@RSLT 4 месяца назад
The intuitive reason is that the probability is a result of having a loop of 51or larger. In other words, it's no longer about the prisoners; it's about the arrangement of the boxes. It was wrong to say that the probability becomes dependent. We need 100 prisoners to guarantee that if there is a loop above 50, they will lose. You could have 1,000 prisoners and still have a 1/3 probability. That is the trick of the video. In other words, we don't calculate the prisoners' loss probability; we are calculating the probability of a loop being 51 or higher versus a loop being 50 or less.
