[Steffen Nyeland 10]

For another 16 hours on https://www.packtpub.com/free-learning - as the free book of the day.

Thanks for the tip!
Nice reading.

 

Note that the chapter about multi-thread friendly MM does not take into account the memory consumption of each, which is a pity.

In short, FastMM4 is very conservative (consume very low RAM), ScaleMM2 define a per-thread heap so will eat more memory, but it is worth saying that I have seen the Intel TBB MM eats hunderth time more memory than FastMM4 (with peaks at 200x RAM consumption).
So I never was able to use TBB on production. Almost the same for jemalloc. Under Linux, a modern glibc has also a great speed - but is a bit paranoid and sometimes SIGKILL the process on some memory error in end-user code.

And perhaps don't switch the payment context to Europe (it's free anyway).

No, it still works when switching to Europe.

[Sherlock 663]

Well, it was just a guess 🙂

You can only read it online but not download it, right?

[Markus Kinzler 174]

It can be downloaded in different formats (PDF. EPUB, MOBI)

[ŁukaszDe 38]

I can only open in online reader.

[Markus Kinzler 174]

Look at the right side of the header in the online reader.

[Daniel 417]

😉 I am feeling a little stupid here. But how can I download this book? There is an option to *buy* the E-Book for 9,99 USD. Maybe this would be the way to go for a download?

[Markus Kinzler 174]

It seems i forgot that I already owned it

Do you have an account registered? That may be the key to getting the free download. I've found the site a little confusing, but once you have a title, you have it registered under your login, and can access it repeatedly.

No, seems there is no more download for free books. The old ones can still be downloaded

[Daniel 417]

I actually can access this book - but only online in their reader. This might be the "limitation" for this free offer.

[Bill Meyer 337]

Maybe. But I thought I remembered having been able to "buy" a free special at the $0.00 price in the past.

@Jim McKeeth Do you pay anything to packtpub - subscription or anything else?

 

That could be the reason.
