+1 UoM over Monash and RMIT.
I would personally go for the MEng (Software) if you can. A lot of the companies specially say 'Preferred Masters'.
UoM is actually widely recognised internally for Software Engineering. Know a couple of people from UoM working at MS (that too as a grad!).
Hi Kaitok,
I've recently enrolled full time in a Cert IV in programming at tafe. Im also doing a web Development Course on Udemy. Do you think this would be enough to gain an entry level position? I really can't afford to do a 3 year degree at uni both in cost & time. I can do further study (another 6 months) if necessary.
Thanks
Uhm, you're looking at a very competitive market with people with degree from Uni.
At this stage I can't really tell if your certificate is enough to gain an entry level position. You need to finish at least 1 semester and see if you really like programming. If you do like it then continue to Diploma, then pathway course to a Degree, also learn some things on the side from Coursera or Udemy or Udacity.
Don't try to push yourself into programming because people tell you the dev jobs earn good money. Junior devs earn as much as Junior in accounting and other professions.
How would you go about finding regular distance intervals along a cubic or higher spline?
Using vector calculus.
Which elliptic integral?
I only remember how to calculate an area of a curved surface. Suppose just work backwards to get the length of the line.
Dunno. I did 12 years of maths in another language than English. I may know the answer if you present the problem in an universal language.
How do you move along an order ^3 parametric curve at constant speed?
Nah… I'll buy you a coffee if you live in Sydney and stop asking these maths questions
OK Google…
@kaitok:
No need :) The answer is really it breaks normal analytic maths, because of elliptic integrals and root limitations, so numeric methods might be used, but then everything is slow. Once that is dealt with, even using 64 bit doubles, the numeric error causes issues. You are better off with just algebraic substitution and iteration.If you try, you will learn a lot about numeric error. Do experiment with analytic cubic and quartic, and numeric root solvers. It is one area of maths that is not limitless. Computer numeric maths helps a lot, but has problems with irrational numbers.
Fun for a one line problem. Maybe the best answer is 'numeric and naive'.
@kaitok:
On a slightly related note, do worship the AGM numeric elliptic circumference length taken from legend Paul Bourke's site. It might look simple, but it's stunningly faster than naive methods.#define MIN(x,y) (x < y ? x : y)
#define MAX(x,y) (x > y ? x : y)double t,tol,x,y,s,m;
tol = pow(0.5,27),
s = 0,
m = 1;
x = MAX(a,b);
y = MIN(a,b);
while (x - y > tol * y) {
t = (x + y) / 2;
y = sqrt(x * y);
x = t;
m *= 2;
s += m * (x - y) * (x - y);
}
len = M_PI * ((a + b) * (a + b) - s) / (x + y);Using doubles to do maths and ignore precision loss. What a joke and you talk about maths and computing.
Still waiting for that job adverts for all those QC jobs. I guess you cant find them given qubits are both advertised and not advertised.
@ninetyNineCents:
Are there popping sounds when you try pluralising? Your dole diary is your own issue.
It doesnt matter, programming is never about math.
The smarter quarter is. It's by invitation only.
THe vast majority of programming has no maths.
@ninetyNineCents:
What do you see as the major non-maths areas of quantum computing? I think you are demonstrating superposition yourself.Really?
You don't see addition, subtraction, multiplication, division, assignment, logical condition (and or xor) as Maths?
A for loop with a counter isnt maths, or adding a few numbers isnt so basic i dont think you need to pretend its maths.
Of course it is, but is it really necessary to try and attach as many names for what you do ?
Are you going to pretend you also do microwave research and communications because you use a Microwave ?
WIth this kind of thinking a anyone who writes a one line batch or script once a year if that is also a software engineer.
@ninetyNineCents:
Given your QC understanding seems to be limited, what math proportion score would you give the following:- the FFT you used extensively just to HTTP the page.
- the antialised fonts used to render the text you are reading.
- GPS signals and trilateration.
- WiFi signal.
- the non-linear colour calibration of your monitor/screen.
- multitouch capacitive touchscreen positioning.
- CAD used to design and manufacture your tablet or monitor.
More generally, what is a FLOP and where does it fit into your mathless world?
Given your QC understanding seems to be limited, what math proportion score would you give the following:
Wow, you must be smart , rather than focus on the discussion you throw an insult.
the FFT you used extensively just to HTTP the page.
So if my dog looks at my screen is he a programmer or mathematician ?
the antialised fonts used to render the text you are reading.
You obviously dont understand the difference between being a consumer and the actual engineer who did all the maths inside said system.
Thats the point of abstraction, it just works, you dont have to understand the maths.
More generally, what is a FLOP and where does it fit into your mathless world?
Here we go again, i never said that at all, i challenge you to quote where i said that.
I simply said that most programming involves no maths and thats true. Its a joke to pretend playing with numbers in such basic form is maths.
Not going to answer the other thread we were sharing a few days back ?
Or is it too hard ?
@ninetyNineCents:
"programming is never about math."You just say the most ridiculous and feckless rot and then think having the last word wins, no matter how hard you crashed and burned and exemplified Dunning-Kruger. If you understand quantum computing, do tell me about how programming one doesn't involve maths. It's not an insult, You have no idea. Elsewhere you overshared way too much, that you know the public toilet habits of minors. Pat yourself on the back for your bizarro and creepy area of expertise. You are truly bereft of logic.
"You obviously dont understand the difference between being a consumer and the actual engineer who did all the maths inside said system."
Who does the programming in that relationship? Why did graphics cards introduce hardware T&L if maths was irrelevant? Do you even understand any part of the SSE instruction sets? You are just telling the world you are neither a computer scientist nor engineer. You wouldn't know maths if it was sitting on a screen in front of you.
I do like your username. A cent short of a dollar. At least you understand subtraction.
If you understand quantum computing, do tell me about how programming one doesn't involve maths.
How many developers in Australia have access to a quantum computer for starters ?
I dont mean any of those toys online but real access and spend considerable time doing stuff. The figure is a fraction of the entire developer community both enthusiast or professional (pay for hire).
It doesnt matter.
Its about as important as knowing about Itanium perhaps less as there are probably more of them somewhere in Australia.
Why did graphics cards introduce hardware T&L if maths was irrelevant?
And 99% of most developers never write shaders etc.
Do you even understand any part of the SSE instruction sets?
And 99% of developers used managed runtimes and never touch assembly.
Most of the worlds developers write web pages, the lang doesnt matter, and none of them ever touch SSE or any of the other TLA you like to name drop.
You are just telling the world you are neither a computer scientist nor engineer
You wouldn't know maths if it was sitting on a screen in front of you.
Really what proof have you got for that ?
Ive got plenty of proof for every one of my statements in this comment.
So how many people do quantum computing in Australia as compared to all developers in the country ? Why would a guy doing PHP writing boring CRUD need to know about quantum computing or SSE or SSE2 etc etc ?
Why ?
@ninetyNineCents:
"How many developers in Australia have access to a quantum computer for starters ?"Every single one, genius.
What kind of idiot are you that you think its necessary to learn skills that less than a fraction of 1% has access to the equipment to try anything.
@ninetyNineCents:
You still don't understand apostrophes. Are they too mathematic for you?Where is your 'plenty of proof' that 99% of developers "used", past tense, managed runtimes and never touch assembly.
Where is your 'plenty of proof' about 99% of programmers using managed runtimes?
Go look at the adverts on any local job site, most are for java, dotnet, android. The value whatever it may be is certainly far closer to 100% than your bullshit pretending everybody is somehow mixed up with quantum computing.
Please show me where 50% of developers do quantum computing….
@ninetyNineCents:
You've gone from having plenty of proof to admitting your numbers are made up recollections from your Centrelink board.@ninetyNineCents:
"Please show me where 50% of developers do quantum computing…."Would that be to support your made up statistics? You made it up. Own it.
Would that be to support your made up statistics?
Yeh im making up stats that practically everybody uses java or dotnet. Obviously your idea that everybvody does or should know quantum computing is more accurate.
In fact your bullshit is so accurate you cant present a single QC job link in Australia today.

Would that be to support your made up statistics? You made it up. Own it.
Given there are ZERO jobs today in Au, for QC why should any significant minority learn about it today ?
@ninetyNineCents:
I don't need to talk about your unemployment situation. Quantum Computing involves intensive maths. You are factually disproven.Quantum Computing involves intensive maths. You are factually disproven.
Of course it does, but i was talking about the typical developer not the three people in Australia who actually have access to a quantum computer.
I said the typical developer does not do maths , and a qc developer is not a typical role.
@ninetyNineCents:
In your nutty reality, how are videogames programmed if they don't involve maths? How about the rendered graphics industry. How do ray tracers and radiosity renderers work if they don't involve maths? How do PID controllers work without maths? Kalman filters minus maths. Why do CPUs even have an ALU, 'A' standing for arithmetic?Your profound words:
"I said the typical developer does not do maths , and a qc developer is not a typical role."
versus:
"It doesnt matter, programming is never about math."Did you manage to phone a friend? Where did your 'typical' revision fall from?
In your nutty reality, how are videogames programmed if they don't involve maths?
They are minority.
Do you really believe those lotto ads where they show everybody winning sorry doing quantum computing…
How about the rendered graphics industry.
Again a very small minority. How many Animal Logics do you think there are in Australia ?
How do ray tracers and radiosity renderers work if they don't involve maths?
There are very few people writing ray tracers ALL over the world.
How do PID controllers work without maths? Kalman filters minus maths.
(profanity) you really are stupid, i said FEW PEOPLE IN AUSTRALIA DO DEVELOPMENT WHICH INVOLVES MATHS.
FEW, NOT ZERO, i said few if any.
Here we go again stupid dick who cant grasp the concept that the typical software developer does not require maths to do their job.
Why do CPUs even have an ALU, 'A' standing for arithmetic?
How stupid are you ?
YOu cant read i will repeat for the 10 th time FEW PEOPLE IN AU DO DEVELOPMENT THAT INVOLVES MATHS.
IN return you respond with bullshit like quantum computing an extremely niche area that would at best employ 10 people in the entire country if that.

It's worth the vigil, knowing it's going into your ears and bouncing around, Nena.What you really are an arsehole you never stop with your bullshit about quantum computing and other technology after someone simply asked is maths needed to do programming.
Is that really a useful honest answer ?
Guess not with your inferiority complex trying to use TLA and failing to use them correctly and making technical mistakes that someone with real working knowledge of said tech would never make.

99: Its a bit like saying nobody wins at lotto of course a few do, but in the end its fair to say nobody does. The math involved is minor for the purposes of our friend it can be called zero.
You dont understand that the simple answer was to say none, after all they dont know that there are 5 people in Australia doing QC etc. It was a simple question and demanded a simple answer, something arseholes like you dont grasp.

You need to go back and read my original reply. Our friend asked if maths was necessary when doing computer programming. I said it was not, and thats basically true. I could have given a 1000 word essay with examples of who and where maths is used, but as a general rule for the vast majority of programmers, there is no maths.
The problem is our friend FR doesnt know how to read or grasp the context of my reply.
Two replies, thats the accountants job, they use a program to do that for them, secondly your ability to do a tax return is not of concern or necessary to get a job.

99: wow you dont know how to do math without precision loss or significantly more digits ? For starters you use an abstraction and not a primitive like doubles.
FR: Proof that you don't even understand Pi is irrational.
99: So what if its irrational, doubles typically only have 53 or so bits in their mantissa, if you want accuracy you will have to an abstraction so you get more bits, and thats the point, but you are too stupid to grasp this limitation and a solution to this problem.
@ninetyNineCents:
Not understanding Pi is irrational, and not caring is as stupid as it gets.99: "So what if [Pi is] irrational"
I never claimed one could get a perfect answer, there are often losses when representing fractional values, it was simple to get more accuracy/precision. The sample had multiple operations and each means slowly errors creep into the lower bits of the computation.
But you dont see the big picture yet again.
It seems like you can still major in computing and software systems.
