html5 - W3C validation error for input type=date - 


<input type="date" max="1995-12-31" class="form-control" id="dob"/>

when try validate w3c got error line:

the date input type not supported in browsers. please sure test, , consider using polyfill.

how solve it?

maintainer of w3c html checker (validator) here. message warning message, not error. , reason have html checker emit warning is, input type=date isn’t supported in desktop safari or internet explorer, nor in versions of firefox before firefox 57, nor on android before android 4.4.

for exact details browser support, see https://caniuse.com/#search=date

so warning’s purpose give heads-up document has feature doesn’t work specified users of internet explorer, safari, , older versions of firefox , android.

that’s why warning mentions consider using polyfill—in order ensure feature works users expected.

to make input type=date work in browsers, can choose among many available polyfills:

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
