I'm amazed at your pricing but it looks from your community forum activity that you have a market. Well done in an era where everyone expects stuff for free.
Yes, I didn't know what it was so I had looked it up before I saw yours. The definition I got is below:
A common table expression, or CTE, is a temporary named result set created from a simple SQL statement that can be used in subsequent SELECT, DELETE, INSERT, or UPDATE statements.
>And that valuation is created entirely due to IP law.
In that case, the value of land is created entirely by property law.
A farmer has the exclusive right to land from the existing fixed supply that the entire world has available to it. He didn't create it and no one else can use it.
Whereas a software developer makes something new. Nobody else was deprived of anything pre-existing. Less justification for taking code from a developer than land from a farmer.
If you're implying that the farmer would still have an income then it's not a valid analogy.
If I open sourced my software that I've been continuously developing for more than 20 years my income would drop to almost zero, immediately.
K A Stroud Engineering Mathematics is probably the book that helped me most.
31 chapters each composed of about 60 problems. The problems are progressive and contain explanations of the new concepts that they contain.
All the answers are at the back.
Good post. Are there any downsides? I use alcohol to excess, a habit I developed in the days when socialising was something I wanted/needed to do but needed help with it.
Firstly I'd say that although there are 180 dental practices, there is only one patient, I think a study would need a lot
more than that.
I cannot read the article but at how many practices did this person have x-rays taken? I doubt it was many if any. How did they get out of that, by bringing their own x-rays with them and saying that they were a recent set from their last dentist who'd retired?
If they didn't have x-rays taken and didn't bring any with them then the dentist would be diagnosing blind to a large extent.
In any case diagnosing cavities is not a binary true/false affair and x-rays can mislead also.
There is a lot of human judgement involved.
Some cavities never need filling, others can increase massively in size over a short period.
Two questions that a dentist will typically ask a new patient are, how long since your last attendence at dentist and are you a regular attender or do you just go when you have problems?
If a new patient is a regular attender, a dentist will be happier to keep a cavity they are unsure of, under
observation. Sometimes they may schedule shorter recall periods for review until such time as they are comfortable that the patient does not have active decay.
Generally a cavity does not need to be filled unless it extends into dentine.
Determing if this is the case is not always straightforward.
Generally a filling does not need to be replaced unless it is leaky.
Again this is not always easy to determine and like programmers, dentists tend to be more critical of other dentists'
output than their own.
Recent experience also colours judgement.
If a dentist has had a run of cavities that turned out to be deeper than expected then they are more likely to diagnose a cavity when unsure and vice versa.
Different sub-populations in the aggregate, depending on wealth, diet, dental hygiene and typical frequency of attendence have different dental decay characteristics which can colour a dentist's judgement.
There are crooked and incompetent dentists just like there are in every job. Dentists in general get a bad rap. One reason I've heard is the fear of dental treatment breeds an instinctive, subconscious dislike and mistrust of dentists as persons. Certainly doctors, despite being equally good at extracting money from their patients don't suffer from the same degree of antipathy and suspicion.
On a tangent. I used to be able play youtube videos on firefox on my old android phone with the screen turned off. It was some setting in firefox that I can't seem to remember or else is no longer there.
It was great because you could listen to a long lecture while walking using up less battery and even more importantly, not inadvertently clicking on something on screen.
Anyone have any ideas if it's still possible?
Years back we rented a flat in a building that housed a lot of retired people.
A regulation we weren't aware of was that you weren't allowed to hang anything on the railings of your balcony.
On a day off we were cleaning and left a mat we'd washed to dry, hanging over the railing. It wasn't there an hour before we had a delegation at our door of angry elderly residents. They weren't one bit nice about it even after we immediately apologised, took down the offending item and explained that we were unaware of the regulation.
Later we got an apologetic call from our landlord who said he was ringing because he'd received a complaint about us.
Thanks. I feel myself that l am too influenced by critics. Years ago I used to go to Blockbuster and come away with random movies based on blurb on the back of the dvd case. Nowadays I'm wary of watching a movie unless it has a great score and lots of reviews on rotten tomatoes. I feel like i'm probably missing out on a lot of hidden gems.
