Google's New Camera App Simulates Shallow Depth of Field

thegarbz Re:Overcoming hardware limitations with software (97 comments)

It's about camera software. You view that it isn't about photography is outright indefensible.

From the first line in the fucking original source:

One of the biggest advantages of SLR cameras over camera phones is the ability to achieve shallow depth of field and bokeh effects

YOU are wrong. Now please take your pointless and irrelevant argument elsewhere.

Google's New Camera App Simulates Shallow Depth of Field

thegarbz Re:Better idea: Improve cell phone camera lenses. (97 comments)

You know what would give a great shallow depth of field? A better lens in the camera. A lens with an aperture that could open up to lower f-stops would give a REAL depth of field effect, plus it would make the camera just plain better at taking pictures -- better low-light performance, less noise in high ISO speeds captures.

A typical phone camera has an aperture of around f/1.8 to f/2.5. You care to tell me how you would get past the laws of physics to improve on this? I mean the lens is already nearly a ball to focus light on such a tiny dot. One could increase the sensor size but then the lens would need more physical separation to the sensor making the thickest component in a phone thicker still.

Software AF is simple contrast detection. Every phone I've used has the ability to select the subject to focus on, so why would this have any baring on depth of field.

Google's New Camera App Simulates Shallow Depth of Field

thegarbz Re:Overcoming hardware limitations with software (97 comments)

Exposure values, or "stops", have little to do with why smaller sensors have greater depth of field.

Correct, however opening the aperture is a workaround to creating as similar an image as possible providing you haven't hit the limits.

Google's New Camera App Simulates Shallow Depth of Field

thegarbz Re:Overcoming hardware limitations with software (97 comments)

I hear comments like this all the time. The reality is you've changed your FoV so you're now taking a completely different picture. If you want all other things staying as equal as possible, then to take the same photo on an APS-C camera as a Full Frame camera you'd need to switch to a narrower lens and step back from the subject. Oh your subject - camera - background ratio now changed, and so has your depth of field.

Or are you going to tell me all camera are equal because if you over expose your image by 100 stops you get a perfectly white frame on every camera?

Google's New Camera App Simulates Shallow Depth of Field

thegarbz Re:"subject" (97 comments)

And, of course, shallow depth of field is a huge fad, and there's an entire generation of kids who won't ever be able to tell where they were in any of their childhood pictures.

Wow lets step back a bit. Though I guess someone called the automobile a fad at some point.
The battle for wider apertures dated back to post war. The 1950s was all about big lenses, wide apertures. I fondly recall using a Canon R mount 50mm f/1.2. Not a very sharp lens but provided incredibly narrow depth of field. Mind you it wasn't until the FE mount in the 80s they managed to get a 50mm f/0.95, something which Leica managed quite a lot earlier on their M series cameras in the 1960s.

Now that the history lesson is over, how about an art lesson. Depth of field is used to direct attention. If you want someone looking at a subject rather than the image on the whole you can isolate the subject by blurring the background. I did this on my holidays and I'm going to look back and think about what I looked like at the time who the hell cares where I was. If I wanted to take a photo of where I was I would do so. Now on the flip side, why the hell would you want to ruin a perfectly good photo of the Pantheon or some other wonderful place by standing in front of it? Why would you want to give up artistic control to some passer by telling them to look through the viewfinder and push the button.

You seem to know the technical details of how something is done, but not have a clue of why someone would do it. Go to your grandpa and ask him if he used wide apertures when he took photos. You'll likely find him don his oversize framed glasses and say "Kid, I was the master of bokeh before it was cool."

Fad indeed.

The Design Flaw That Almost Wiped Out an NYC Skyscraper

thegarbz Re:That has happened quite often here in the US. (156 comments)

Changes such as these are actually not too rare; I suspect that in most cases, the substitutions work exactly as expected, but when we're discussing infrastructure elements of this scope a single failure is not merely troublesome but often catastrophic.

I would say it's worse than that. Changes such as this are actually pretty common. Actually I can't recall a single project I've been involved in where a contractor hasn't proposed some kind of design change. Contractors deal with what is possible and what is there. Engineers deal with what is theoretical and what is shown on drawings.

- Build a tunnel? Submerged rock that wasn't anticipated, contractor suggests slightly altering routes.
- Specify an exotic metal with a weird shape? Contractor says it can't be manufactured / transported to site within the timeframe, suggests slightly different design.
- Contractor builds anything at all which doesn't line up (which always happens), the contractor will ALWAYS suggest an alternative before accepting that they need to rip it out and start again.

The trick is ensuring you get the correct sign-offs in each case. In this case it looks like it was but the expertise wasn't here to recognise the problem. In the case of the Hyatt Regency Skywalk listed in this thread the sign-offs were not correct.

Click Like? You May Have Given Up the Right To Sue

thegarbz Re:The power of EULAs only goes so far (214 comments)

Yes true. I was not implying what could be legally enforceable in a contract, but what would legally constitute a contract to begin with.

Case law is full of examples where a contract is completely void if it was not read and signed under the full understanding and normal method of entering a contract. That is to say I can't simply write even legally enforceable text such as "By signing below you agree that I may contact you for advertising purposes" on a receipt for a hammer you just purchased. Even though reading and signing a statement like that is legally enforceable, it needs to be a contract separate from any other function such as signing a credit transaction, signing for a parcel, or hitting like.

The only way a contract is enforceable is if it's separate, hence the tick boxes allowing opt-in or opt-out for advertising and other "commercial material" when filling out forms not related to you wanting to get said advertising.

Switching From Sitting To Standing At Your Desk

thegarbz Re:Weak? No, it is not. (310 comments)

Erm there's a lot of Asians who would like to say something about your example. Mind you I'm a massive fan of Sashimi, Sushi, Steak Tartare, quite often I also eat it with ... salad. Yes unbelievable I know. I have no idea how I'm still alive either.

We can eat almost anything RAW though I agree about the rice part. RAW rice digests as well as nuts and corn, which is to say it doesn't at all. That said as for my cat, why the hell would you feed a cat RAW rice? If you cat has a stomach virus you're supposed to feed it cooked rice. I'm not sure you'd even get a cat to eat rice without cooking it in chicken stock. Oh and you live in some weird area if you think wild Apples aren't edible. Sure they don't weigh 100g like the one from the shop but have you ever thought of just eating two of them?

Your comment not only doesn't make sense, it actually goes against common dietary advice. Go eat some salad, or better yet join the latest health food craze and buy a juicer and make raw vegetable juice. It's delicious and nutritious. Except for kale, juiced or not juiced that tastes like shit, I don't care how good it is supposed to be for you.

New Facebook Phone App Lets You Stalk Your Friends

thegarbz Re:Get off my lawn time.. (61 comments)

The problem is that life doesn't happen. How do you form a spontaneous meetup? I don't live in a country town. There could be 30 of my friends at my local shopping centre all day and I wouldn't bump into any of them. There's some 40 cafes within 2km of here, about 4 different cinemas, two of which are megaplexes and will show popular movies every 1 hour, hell even on the more esoteric side there's 3 bowling alleys within that 2km radius as well.

The modern world is massive and we are spread thin. I tend to let life happen too and I end up with constant exchanges afterwards like
"Yeah we went to see Captain America."
"Oh really? We saw it at the same time but at %other shopping centre%."

The whole point of the world of information sharing is to get people together so that life can happen. I would say it's been probably about a year since I last bumped into someone randomly and changed plans so we could have a quick coffee or spend the afternoon together.

Vintage 1960s Era Film Shows IRS Defending Its Use of Computers

thegarbz Re:Anecdote: you're wrong about the IRS... (146 comments)

I got one of those from my local ISP. They overcharged me 20c when I left them for a better deal elsewhere. I'm malevolently not cashing it. They send me a monthly reminder that my account is in the positive asking me for my details to refund. They way I figure it would have cost them over $10 already in mailing me the reminder letters.

Switching From Sitting To Standing At Your Desk

thegarbz Re:Weak? No, it is not. (310 comments)

I can't agree with your view on the digestive system. Yes it's complex, but there are many animals out there with far more complex digestive systems yet with very little tolerance to diet changes.

We can survive on only meat, only vegetables, we can consume dairy or cut it out of our diets completely. We're the only animals which eat rice and can digest it as well (feed rice to a cat to clear out it's digestive tract, it looks the same when it comes out as when it goes in).

It may be complex but there's very little out there which we can put in our mouths from which our digestive system can't extract even some minor nutritional value.

GoPro Project Claims Technology Is Making People Lose Empathy For Homeless

thegarbz Re:Spare Change (318 comments)

Hmmm single and 20-40 would qualify for healthcare card, new start allowance, and food coupons even if I didn't have public housing. Of interest is that we have a rental property we are currently tenanting with jobless person who is in the exact predicament you're describing. Male, 35, no job, no savings, yet never behind on his rent and as far as I know they are still alive. Now things may be different in America where people are genuinely in a bad place, but there's no excuse for it in many countries.

It's a free world. If you want to drink yourself to death on the street go for it. You have every opportunity including free counselling sessions to break out of your cycle. Just don't expect me to drop another dollar in your empty grande starbucks cup.

Signed? Actually no. It's only signed if if I tick a box saying I've read it before I hit like. Simply hitting "like" can not imply that I've done anything. Even a casual litigant wouldn't be deterred by this. Sounds more like a bored legal team had nothing to do on a Friday afternoon.

GoPro Project Claims Technology Is Making People Lose Empathy For Homeless

thegarbz Re:Spare Change (318 comments)

The homeless have a right to drink. They do not have a right to empathy.

Tell me again why a homeless person (who qualifies for a healthcare card and thus free trips to the doctor and insanely discounted drugs in my country) would buy a $50 bottle of scotch every other day for his pain rather than spend $5 on drugs that will last them all week.

They can drink as much as they want. Just don't expect me to fund it with my lunch money.

With the amount of social security many countries doll out the only reason homeless people are homeless is because they want to be, not because they have no opportunities.

GM Names Names, Suspends Two Engineers Over Ignition-Switch Safety

thegarbz Re:Hero ? (236 comments)

You would do wise to remember your history.

In that case a group of engineers recommended no launch. Their management backed them. NASA strongarmed the resulting discussion. The engineers made it known to both Thiokol and their customer / end user NASA that they oppose the launch. There's not a heck of a lot more they could do other than run into mission control guns a blazing to stop the launch.

From what I can gather in this case the engineers appeared to engage in a cover-up, quite the opposite from vocally speaking up as in the Challenger case.

If you think change management isn't a fundamental responsibility that needs to be upheld then that's a scary connotation. Yes in this case the part got fixed. No it wasn't sufficient on their behalf, it wasn't in-line with what anyone would consider typical engineering practice (where's the mountain of documentation detailing the change?), and it wasn't sufficient resulting in people getting hurt.

GM Names Names, Suspends Two Engineers Over Ignition-Switch Safety

thegarbz Re:Hero ? (236 comments)

Except there's no involuntary unemployed engineers. Why not open the career section of the paper and just see how in demand mechanical and electrical engineers are. In the height of the GFC they were in demand, and now they are still in demand. Stop comparing this situation to some unskilled labourer you're not helping your arguement.

You're making excuses for someone who acted against the ethics of the profession. Just remember that next time your children go to the doctor and don't get the right treatment because of budget cuts and management. (See what I did there? Think of the children!) Oh what? The oaths can apply to one profession but not the other? Please.

GM Names Names, Suspends Two Engineers Over Ignition-Switch Safety

thegarbz Re:Comparison to code bugs a bit flawed (236 comments)

I don't think so. Ethical does not mean "thou shall not kill". Am I working on a device intended on killing others, or am I working on a device intended on saving our own?

I think the word ethical here is a bit of a catch. Ethical doesn't necessarily mean a religious following of one's beliefs, but rather the code of ethics I signed are based around the tenants of demonstrating integrity, practising competently, exercising leadership, and promoting sustainability. Part of exercising leadership is that you can not sign your rights away to non engineers. Where I live this is actually covered under law. I as a registered engineer can't have a manager sign away liability for something I know is not safe, I can only sign that away to another engineer, and only to another engineer who is competent in understanding what is being signed (practising competently).

I know not every country holds the engineering profession to this high standard but the way I see it, even if in this case the engineers in question fixed the problem, they helped sweep it under the rug for management and I have no problem with them being grilled in a public forum for it.
