I see requests to socket.io containing parameter t to be like LZywzeV, LZz5lk7 and similar.
All examples that i found so far used second- or millisecond-based UNIX timestamps.
Has anyone ever seen a timestamp format like this? (It is not base64-encoded).
I started looking a site that uses Socket.io today, and got the same problem, trying to look for the protocol definition was useless.
I figured this format is something called yeast
TBH, really don't know why people invent this sort of things instead of use
base64(timestamp.getBytes())
pseudocode instead.
A yeast decode algorithm in Python is as follow:
from datetime import datetime
a='0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-_'
b={a[i]: i for i in range(len(a))}
c=0
for d in "LZywzeV":
c=c*64+b[d]
print(c)
print(datetime.fromtimestamp(c/1000))
The output of that code is:
1481712065055
2016-12-14 07:41:05
to #jeremoquai:
It is easy, is matter of invert the algorithm:
def yeast(d):
r=""
while d!=0:
r='0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-_'[d&63]+r
d>>=6
return r
so, if you run
yeast(1481712065055)
it returns LZywzeV

I've been using the first version of PHRets v1 for years, and understood it well enough to get by, but now I'm trying to understand the advantages of v2.6.2. I've got it all installed and the basics are working fine. My issues are pretty much with comprehending fine points of query syntax that goes into the rets=>Search() statement. (I'm much more familiar with SQL statements). Specifically, I'd like to have a query return a list of properties, EXCLUDING those which already have the status of "Sold".
Here's where I am stuck: If I start with this
`$results = $rets->Search('Property', 'A','*',['Select' => 'LIST_8,LIST_105,LIST_15,LIST_19,listing_office_shortid']);`
That works well enough. BUT I'd like to fit in a filter like:
"LIST_15 != Sold", or "NOT LIST_15=Sold"...something like that. I don't get how to fit/type that into a PHRets Search().
I like PHRets but it is so hard to find well-organized/complete documentation about specific things like this. Thanks in advance.
As in my comment above I've figured out that the filter goes in the third argument position ('*', as in the original question). The tricky thing was having to find a specific "sold" code for each class of properties and placing it in that position like so: '(LIST_15=~B4ZIT1Y75TZ)', (notice the =~ combination of characters that means "does not equal" in this context). I've found the code strings for each of the property types (not clear WHY they would need to be unique for each type of property: "Sold" is Sold for any type, after all) but the correct code for a single-family residential property (type 'A' ...at least for the MLS in which I have to search is:
$results = $rets->Search('Property', 'A','(LIST_15=~B4ZIT1Y75TZ)',['Select' => 'LIST_8,LIST_105,LIST_15,LIST_19,listing_office_shortid']);
(again, the code to go with LIST_15 will be different for the different types of properties.) I think there is a better answer that involves more naturalistic language, but this works and I guess I will have to be satisfied with it for now. I hope this is of some use to anyone else struggling with this stuff.
I am trying to create a data field using Mockaroo and they say they have Ruby support but I know nothing about Ruby so I am trying to find out how to do a field that will randomly choose between the 3 options.
now() or
now()+days(-1) or
now()+days(-2) or
now()+days(-3)
Idea 1
I was initially thinking something using random like now()+days(this.rand(-3))
Idea 2
I also thought of using or logic like now() or now()+days(-3) or etc...
This answer may end up being different than a typical ruby solution since Mockaroo has their own little API to use too... Appreciate any help that can be given.
Turns out I had to use the random function first and pass in min and max date parameters.
random(now()+days(2), now()+days(-3))
I'm trying to figure out what is the most efficient way to parse data from a file using Lua. For example lets say I have a file (example.txt) with something like this in it:
0, Data
74, Instance
4294967295, User
255, Time
If I only want the numbers before the "," I could think of a few ways to get the information. I'd start out by getting the data with f = io.open(example.txt) and then use a for loop to parse each line of f. This leads to the heart of my question. What is the most efficient way to do this?
In the for loop I could use any of these methods to get the # before the comma:
line.find(regex)
line:gmatch(regex)
line:match(regex)
or Lua's split function
Has anyone run test for speed for these/other methods which they could point out as the fast way to parse? Bonus points if you can speak to speeds for parsing small vs. large files.
You probably want to use line:match("%d+").
line:find would work as well but returns more than you want.
line:gmatch is not what you need because it is meant to match several items in a string, not just one, and is meant to be used in a loop.
As for speed, you'll have to make your own measurements. Start with the simple code below:
for line in io.lines("example.txt") do
local x=line:match("%d+")
if x~=nil then print(x) end
end
I'm trying to use a relatively basic IF function but having no luck - i'm sure i just have brackets or parenthesis wrong or something. Reckon it will be childsplay for you guys....
The formula is intended to show how many days a date has passed by. Date is shown in T column.
Basically it was working fine as the following, both for pending and past dates:
=IF(T7<=TODAY(), (TODAY()-T7),-(T7-TODAY()))
But I got greedy and wanted it to return more of a statement when the date has passed, as to how much it has passed by. So I've tried to make this happen with:
=IF(T7<=TODAY(),"EffOut(TODAY()-T7) days ago",-(T7-TODAY()))
Hoping it would enter "EffOut 8 days ago" (when TODAY()-T7 is 8 days) for example.
But it doesnt - it shows the entire argument i.e "EffOut(TODAY()-T7) days ago" in the return cell.
Is it possible to have a kind of embedded formula in the 'value_if' fields, mixed with text in this sense?
Happy to share the document if that would help, but will need to clear the data first so just let me know.
Thanks in advance, any help is much appreciated! Having read other posts I think it will just be a simple fix but its well beyond me! (I only got this far by perusing forums...)
Maybe something like this...
=IF(T7<=TODAY(),"EffOut "&DAYS(TODAY(),T7)&" days ago",-(T7-TODAY()))
=IF(T7<=TODAY(),"EffOut "&(TODAY()-T7)&" days ago",-(T7-TODAY()))
You just need to be careful to put "" around any strings. This is how Excel knows that's not a part of the formula. Remember to out the spaces is to the string like I did above so it looks like a sentence. The & sign combines the results of the calculated parts and the strings.
I have a list of the following codes and their corresponding codes in format code_128. I want to given a string, be able to generate the corresponging code in CODE_128 format. Based on this list, how could I generate a code_128 number to the string A4Y9387VY34, for example?
code code in code_128
A4Y9387VY34 ????

I read a lot about it, but I didn't come to any solution. Thanks in advance!!
Well, this is a pretty open question, I will give you my suggestions:
If it is a finite list, you can use a Hash or a Dictionary, where
the keys are the Codes and map them to the corresponding value, in
your case, Code_128
Some scanners have software installed that allow you to change what
has been read to a new value, format it, etc.
If you need a bigger insight please, give us more detail about the environment you are using.
Hope that helps,
I decided to create a new answer because now I get your point. Well, if you are talking about a GS1-128 Code (please see www.gs1.org) please do not start without visiting Wikipedia info about it. as you can see, there is a thorough explanation about how to work with that type of code. That code is composed by several application identifiers followed by their corresponding values. There is a better way of encoding them by using special characters as parenthesis. Here is other info that may help you.
Hope it helps,
