Flu vaccinations have repeatedly been shown to be harmless and potentially beneficial, even if they have no particular benefit to nurses above the normal benefits to the general population then it is simply that they are mandated by the employer who knows that during the flu season nurses will be especially in demand and they cannot afford to have too many off sick with flu ...

If your job requires you to come in contact with flu patients, then you are more likely to get flu, so are more likely to be off work when needed, and more likely to transmit flu to vulnerable patients (since you have it where the immunised do not)

This is irrespective of whether the flu jab has any effect on transmission of flu by non-infected people ...

If the only reason not to get a flu jab is 'religious reasons' then you simply should not be doing the job....how many other parts of your religion also conflict with your job as a nurse, (do you refuse to treat people on religious grounds?)

Comment Re:C reality check (Score 1) 535

C is very low level, very general, and very very portable, so it is almost always the first thing on any new system as it allows you to then implement many other systems

Most languages allow you to bootstrap via C because of this, and it can be assumed that there is a C compiler for almost any system so it is used as the base of many systems, or to extend many systems ...

This does not make it good, just popular ...

The words Bootstrapping compiler spring to mind ...

The GCC compiler was written in C, and is now being used to rewrite the GCC compiler in C++ and the C-GCC compiler will be used to compile it initially

LLVM was compiled using a C based compiler then LLVM used to compile itself ...

Almost all compilers were originally assembler, then C, then bootstrapped themselves ...GCC is unusual in that it (until recently) still compiled via C ...

C is not a good language, but it is not a bad language, is very general, is very simple to implement on a new system, is very small (for the basic language), and brings huge amounts of code with it if you do ...so it is implemented on most systems

C has multiple standards, not everything is implemented everywhere ...

C has issues mainly because it is a very old language, this is what C++, Java, C# and many others were designed to address to varying levels of success ...

There are a large number of other languages widely used and widely ported that are by many definitions better than C, but they are either domain specific, propitiatory, or not well known outside specific industries ....

..What is the C++ compiler written in ... probably C

what is C++ compiled via in this compiler, probably C

i.e. C is very low level and can express any programming construct, but it might be simpler to express in C++

C++ cannot be more efficient when compiled (unless you just have a better compiler) since it is just machine code

There may be libraries for C++ that are better, more efficient, and do not currently exist for C, but this just means that they have not been written for C not that they cannot be (it may be very difficult to, or it may be pointless to implement, because it directly uses features that only exist in C++)

Having said that I don't rate either ...

One of the original signatories of the convention of the Metre in 1875 was the USA ...

The US Customary units in everyday use are defined in terms of metric base units

US Dollars were one of the first decimal currencies

Most of the products you buy are manufactured in Metric and sold in metric but labelled with both metric and US Customary units ...

The US military and US scientists use metric almost exclusively, and many businesses use metric so they can deal internationally

It's not a case of when you go metric, it's just when are you going to finish....

It's all a trick due to the weirdness of quantum states trying to be defined in classical terms

They change the quantum state of atoms with almost no energy, to a higher energy state and keep them there using less energy than the change in state ... so in classical terms the energy had to come from somewhere and so the average temperature must have gone down.... but the missing energy is not really missing and the real temperature is still positive ...
