doc_holliday | 8 years ago | on: Don’t buy the MacBook Pros even on sale, in my opinion

Yeah, I was thinking of similar, would be good to see how it works out for you. There's obviously the command line tools for building, but I would miss the integration of Xcode as an IDE for iOS storyboards etc.

Otherwise I've been looking at using remote servers from macincloud.com / xcodeclub.com, but haven't tried that yet.

Damn, my Macbook Air 2013 logic board just gave out, and was considering the upgrade to Macbook Pro 2017 as logic board is running at £450 replacement cost.

After reading other's thoughts here, I think I have to avoid Macbook Pro for now, I hope they change this in the next release.

Annoying as I need a machine with Xcode.

Video encoding would be stateless. There is no reliance on previous runs / state.

Lambda is designed to be used for tasks like that, such as resizing images, parsing file etc.

doc_holliday | 8 years ago | on: Instant scale with AWS Lambda (2017)

Lambda has a long way to go, it's a promising product but if you want to develop anything for it, it's a bit painful and archaic.

I've had issues with the temp memory. It is completely unreliable, you have to store files when processing in /tmp/ and for whatever reason, reading from this results is patchy. I had to resort to storing every file I process in the RAM.

The tooling is only just taking off now, 6 months ago simulation was painful, at least there is AWS SAM now and docker support.

However despite the pain, it's giving me a solution for scalable video encoding that is very cost competitive and I don't have to worry about submitting jobs and monitoring resources.

doc_holliday | 9 years ago | on: Technique makes more efficient, independent holograms

As far as I am aware no one has ever made a proper holographic game, as in a game with parallax on the display.

Most true holographic displays are still under lab conditions with high power lasers, expensive optics and precision setup. Maybe someone at a lab has hacked together a game of sorts though.

You could probably create a sort of holographic game with a lenticular display. You would have slight parallax with a couple of views, it would be quite rudimentary though but a fun project.

doc_holliday | 9 years ago | on: How to never complete anything

The number one thing to remember is almost no one cares what tech you used. Just get it shipped.

People have built million dollar business that had it's first iteration in MS Excel, if it is useful to someone and kind of serves the purpose then that is enough for a start.

doc_holliday | 9 years ago | on: Snap Jumps in Debut After App Maker Raises $3.4B in IPO

I know that the Snapchat platform is worth something, it has high engagement and adoption of 18-24 year old age segment, and that is worth a lot in terms of attention and advertising $s.

However, this just feels completely out of proportion to earnings and downside does not seem priced in. Willing to be proved wrong of course, but especially seeing as they are non voting shares, I cannot understand this pricing.

doc_holliday | 9 years ago | on: Show HN: $2 incremental pricing logo project

Do you the offer service aswell for logo design being made in both iOS and Android icon styles?

I would be tempted to hit it at this price, but want something I can get out into iOS and Android icon easily.

doc_holliday | 9 years ago | on: A Deep Dive into HandBrake and Video Transcoding

Also, reading back, this is a huge huge red flag:

> "I dumped all the images into separate PNG files, and then used sips to convert the PNGs to somewhat-more-reasonably sized JPGs"

You are adding further compression to the PNGs (the frame grabs) by using JPEG (I assume you are using it in lossy mode), which is basically adding another form of compression to your results.

The fact you used JPEGs (further compression) for comparison basically null and voids all the results I am afraid.

doc_holliday | 9 years ago | on: A Deep Dive into HandBrake and Video Transcoding

Some interesting analysis here, but I think you are analysing a video far too heavily in the spatial space i.e at frame level, this doesn't particularly give reliable results as compression and hence artifacts can vary according to frame in time.

Video needs to be analysed ideally in the temporal space (i.e as a sequence). I see no mention of the GOP structure or length of the encoding chosen, which would need to be considered.

For example the one frame you have chosen to compare could be an I frame in some of the video compression or could be a P or B frame which would result in slight variance in quality and artifacts.

doc_holliday | 9 years ago | on: UK Government is breaking the law by collecting everyone's internet data

Yes, you are right in strict definition that they won't know specifically which app you used to visit a site. Yes you visited for example Hacker News (according to the IP log) but they wouldn't know which of the many Hacker News apps you used to visit it. That is right and accurate, so yes they don't know which specific app you used.

However, the use of the term app is probably more to do with vast usage of apps to now consume the internet. So if you now just use the term "website", many of the general populace (who aren't technical) will think that's fine they won't know because I use apps for Facebook etc.

It's important people know that this covers access through apps. So they simplify the usage of that term.

Technically incorrect yes, but probably a proper description for general readers.
