Deconstructing a 6502

I have mentioned previously some people who have done unbelievable things in computing, often in their spare time.

But these four guys did something else that is completely unbelievable: Barry Silverman, Brian Silverman, Ed Spittles, and Greg James wrote an emulator for a 6502 which does not depend on a manual of opcodes. They actually dismantled a 6502 to find out exactly how it was constructed.

Then they wrote a visual emulator which reproduces the work which the basic components (3500+ transistors) are doing.

This emulator does not emulate what the 6502 is supposed to be doing. It emulates what the 6502 is actually doing!

It’s an amazing achievement. The emulator can correctly emulate undocumented opcodes because it is doing what the basic components would be doing!

Now that they have conquered the 6502 they have started looking at other chips.

You can access their website here.

And here is a video where Michael Steil give a very good explanation of what the team did and how they did it:

Building a Computer

I mentioned in a previous post that Ben Eater has a brilliant series of videos on building a computer from scratch.

He had a new series which is very good on building a computer using a 6502 microprocessor.

This is the microprocessor that I know best as it was in my Apple ][ and in my Atari 800.

Here is a link to his website where you can watch the videos (there are eight as I wrote this) and also buy the kit from him.

Here is the first video in the series:

Star Trek Picard and Game of Thrones

I described my disappointment with STP in my last post.

In this post I just want to link to a very interesting video where “Major Grin” shows how Alex Kurtzman admits to being influenced by the success of Game of Thrones and  wanting to introduce a “darker tone” into the new Star Trek series. He says “nobody complains about having to pay for GOT so we have to do the same”.

He also shows us how comfortable is he with “the F word”. He thinks that introduction of swearing into Star Trek is “kind of wonderful”.

The video has quotes from Kurtzman and also has scenes from both Discovery and Picard showing where these series paid homage (to put it kindly) to GOT.

The man is an idiot imho. If we want to watch GOT then we will watch that. If we want to watch Breaking Bad then we will watch that. Your job was to give us new Star trek.

Six things I hated about Star Trek Picard

I mentioned in a previous post how disappointed I was with Star Trek Discovery (STD).

In spit of that, I managed to get a little excited about the prospect of Star Trek Picard. I guess the excitement came from Patrick Stewart and the character of Picard.

So how that season one is over, I can list (in no particular order) six things I hated about STP.

Disclaimer: because the show was so  poor, I wasn’t paying the closest attention. So please forgive me if I overlook something or if I get something wrong here.

1) The swearing, the gore, and the violence

This is mindless and gratuitous. It was unnecessary and has no place in the work of Star Trek. I will come back to this again in another post.

2) Major things that make no sense to me

The Romulans (specifically the “Zhat Vash”) have been working for generations to prevent devastation from synthetics. So when they finally bring their fleet to the Android planet, they are unable to kill the androids firstly because of some trickery, and then because Riker arrives with his fleet. These are supposed to be fanatics which have had visions about the devastation which synthetics will bring. They don’t seem to behave like true believers when the chips are down and all of their fears are coming to life right in front of their eyes

3) Minor things are make no sense to me

What the hell was that all about when those flowers (?) came up and brought down our heroes’ ship and the Borg ship?

What the hell was that mysterious device all about and how were the Romulans tricked by projections of non-existent ships?!

What was that about when our heroes went to that planet in stupid disguises (hats and eyepatches!) and, in Picard’s case, with a stupid accents?

4) Picard becomes an android

In the final episode, Picard dies and his consciousness is transferred into an Android body. But:

  • That body has been designed to look like him and to have his physical characteristics (strength, age, etc.)
  • We are asked to accept that the transfer was complete and that the Picard we know and love is in that new mechanical body and all set for season two

5) The story arc of Dr. Agnes Jurati

Agnes is given the vision of the devastation which synthetics will bring to the galaxy. She is so affected by that that she kills her mentor and lover. But:

  • She is never held to account for that murder. I don’t know if anyone even rebukes her about it! She should have to stand trial for that murder
  • The effects wear off so completely that she is able to tolerate and even help the actual synthetics a few episodes later!

6) Elnor

I am trying to imagine the writers room when they came up with this character:

  • We should have someone who looks like an elf from Lord of the Rings
  • Oh yeah. And he should fight with a sword and throwing weapons like a ninja
  • Yeah and he will somehow be able to hold his own in fights with people who have phasers and the like
  • Yeah but he should be sort of naive and innocent and not really know what is going on most of the time

Pathetic really.

There are more things I could talk about but I think I’ll leave it there for now. It was nice to see Riker, Troi and Seven appearing but tbh I didn’t really like what had been done with their stories in the intervening years.

One final note: I don’t know why Picard had two Romulans working for him at the start of the season, but I liked that Irish actress Orla Brady played the part of Loris and that she did not hide her own accent. It was fun to see a Romulan with an Irish accent

Tough Week for Clowns!

Last week was a tough week for the clowns to the east and west of us here in Ireland.

The evil clown to the east, BoJo, was told by the Supreme Count that he had acted “unlawfully” in trying to suspend parliament for 5 weeks. This was a unamimous judgement by all 11 judges.

The evil clown to the west, DonDon, was told that an impeachment inquiry has (finally!) been launched against him. Of all of the things which could have lead to such an inquiry, the one which finally did is in relation  to his dealing with Ukraine.

A tough week indeed for evil clowns, but a great week for people like me who hate them!

 

Best Quiz Show – The Chase

When I was traveling to Cork a lot last year for work, and staying in a hotel at the airport, I would find myself back in my hotel room early in the evening and turning on the TV to find something to help me relax. That’s when I discovered “The Chase”.

The Chase is the best quiz show on TV by far.

In the past I have enjoyed “Fifteen to One” and “The Weakest Link”. And I still enjoy watching “Who Wants to be a Millionaire” occasionally.

But I am addicted to The Chase.

The format is just perfect. The focus is very much on the questions. And the elimination element provides just the right level of jeopardy.

And Bradley Walsh is a great host. He has a great way with the contestants, and the chasers. And he’s very funny.

I think he’s related to my cousins. And I didn’t think I liked him before I became addicted to The Chase. But now I love him.

I even went so far as to check to see if I could be a contestant. But it’s limited to people who live in the UK unfortunately. And much as I would like to take part, I think moving to the UK is too high a price!

Here is a picture of Bradley and the chasers:

Star Trek Voyager

I had never really watched much STV until recently.

I decided to give it a chance for three reasons:

  1. It is easily available on Netflix
  2. I figured I should give it a try after the disappointment of STD
  3. I listened to an interview with Kate Mulgrew on Ryan Tubridy’s radio show and I was really, really impressed by her

I decided to watch all of the episodes with an IMDB with the highest ratings, generally 8.6 or higher.

The following is a list of the episodes I watched:

Star Trek Voyager Episodes
Episode Title
S03E23 Distant Origin
S03E26 Scorpion: Part One
S04E01 Scorpion: Part Two
S04E08 Year of Hell: Part One
S04E09 Year of Hell: Part Two
S04E14 Message in a Bottle
S05E02 Drone
S05E06 Timeless
S05E10 Counterpoint
S06E12 Blink of an Eye
S06E26 Unimatrix Zero: Part One
S07E01 Unimatrix Zero: Part Two
S07E24 Endgame Parts One and Two

 

I have reached the following conclusions about the series:

  1. The series is quite good, and some of the episodes are very enjoyable
  2. It took until near the end of the third season for an episode to reach the 8.6 rating
  3. The series ended on a high, with an enjoyable episode also rated at 8.6
  4. I can see myself going back to watch more episodes. For example, I see there is one which features George Takei as Captain Sulu

Since I wanted these episodes, I saw a video of Kate Mulgrew being interviewed and the interviewer mentioned that STV is the most watched Star Trek series on Netflix. So I’m not the only one who is rediscovering this series.

Star Trek Discovery – the first two seasons

I did a post about STD before.  That was after watching the first two episodes.

I have now watched the first two seasons. And things aren’t much better.

The main problem is still the same: I can see no reason to like the central character, Michael Burnham.

In the first two episodes she had committed mutiny, started a war, and failed to save the life of her captain.

Since then she has fallen in love with a Klingon who has been converted to a human (Ash Tyler – I don’t really know what that is all about) and she seemed to spend most of season two crying for one reason or another.

The series is littered with unsympathetic characters: Burnham, Tyler, Lorca, new Georgiou, Leland, etc. How does any showrunner expect people to like a show where there are so few likeable characters?

Some people do like Doug Jones(Saru) and Mary Wiseman (Tilly). I quite like Tig Notaro (Reno).

But the main glimmer of light was the appearance of Anson Mount, Ethan Peck and Rebecca Romijn and Pike, Spock and Number One respectively. But that is only for another potential spin-off show as there is no reason for them to appear in the next season.

The most interesting episode was the one where they go (for no real credible reason) to Talos IV, linking back to “The Cage” from TOS.

I also recently watched the extra short episodes which are available under “Trailers and More” in Netflix. Nothing of any real merit there either.

The show has a rating of 7.4 on IMDB (compared to 8.3 for TOS, 8.6 for TNG, 7.9 for DS9, 7.8 for Voyager, and 7.5 for Enterprise).

Here is a picture of Pike, Spock and Number One:

Yesterday by Richard Curtis

Let me start by saying that it’s a genius premise for a movie.

No – I don’t mean the idea that you could write about a world where a guy discovers that he’s (almost) the only person to know the songs of The Beatles.

I mean the idea that you could create a movie which really just features a series of Beatles songs one after the other!

I went to see this movie a few weeks ago with the family. We all enjoyed it really, but that was more about the songs than anything else.

I am a long-term fan of Richard Curtis (he was involved with Blackadder, Spitting Image, Four Weddings, Love Actually, About Time, etc. after all) so I was happy to go to see it. Not his best work though.

It does score 7.0 on IMDB though (which unbelievably is the same score as Four Weddings!) The Rotten Tomatoes ratings are probably a better guide being 63% and 89% respectively from critics and audience (Four Weddings got 96% from critics).

Himesh Patel does well in the lead role, and Lily James (although she doesn’t have much to do) really lights up the screen. And hats off to Ed Sheeran for being willing to appear as himself and for having to good humour to say and do the funny things which were asked of him.

Here is a picture of these three (Gareth Cattermole/Getty Images):

Rutger Hauer

Rutger Hauer passed away on the 19th of July, aged 79.

It must be great to know that you have created something which will never be forgotten. I am referring, of course, to his portrayal of Roy Batty in Blade Runner (1982).

The genius behind Blade Runner was Ridley Scott, of course, but Rutger made an unforgettable contribution.

He is also remembered for other movies, including 1986’s The Hitcher.

And for his role in a series of ads for Guinness.

Here is his iconic final scene in Blade Runner, which apparently was improvised to some extent.
