I am developing a website with a web font that runs on apache.
On google chrome on android (desktop and ios is fine) I am seeing those weird characters. I first thought of an encoding problem, but those characters are not replacing any character they just popup in between characters.
How to solve that?
Solved: I had hidden characters in the text. Probably from copy pasting it. Removed it and wrote it again by hand.
Without more details, it's a bit harder to tell.
One way to diagnose this problem is to use a command like od to perform a data dump on the index file and finding out what is holding up that space.
You can perform that by running: cat index.html | od -cb for example and receive and output that will look like this:
0000000 < h t m l > \n < b o d y > \n
074 150 164 155 154 076 012 040 040 074 142 157 144 171 076 012
0000020 < p > S a f e t y a n
040 040 040 040 074 160 076 123 141 146 145 164 171 040 141 156
0000040 d s e c u r i t y a r e p
144 040 163 145 143 165 162 151 164 171 040 141 162 145 040 160
0000060 r i o r i t y o n e < / p > \n
162 151 157 162 151 164 171 040 157 156 145 074 057 160 076 012
0000100 < / b o d y > \n < / h t m l
040 040 074 057 142 157 144 171 076 012 074 057 150 164 155 154
0000120 > \n
076 012
0000122
Then you'll be able to better determine what is going on.

how can I read it in a list of list of int in haskell?
I have tried few options but I could not manage to do it. I am very new to haskell so please be patience.
First break your input into lines using lines:
let test = "1 2 3 4\n 5 6 7 \n 4 2 5"
let rows = lines test --literally "lines test"! Beautiful, eh?
Result:
["1 2 3 4"," 5 6 7 "," 4 2 5"] :: [[Char]]
Then, extract individual numbers as strings using words:
let nums_as_strings = map words rows
Result:
[["1","2","3","4"],["5","6","7"],["4","2","5"]] :: :: [[[Char]]]
The last thing to do is convert these strings to integers with read:
let numbers = map (map read) nums_as_strings :: [[Int]]
Result:
[[1,2,3,4],[5,6,7],[4,2,5]] :: [[Int]]
Or, squashed into one line:
let numbers = map (map read) (map words $ lines test) :: [[Int]]
Example with your data:
Prelude> let test = "1224 926 1380 688 845 109 118 88 1275 1306 91 796 102 1361 27 995\n1928 2097 138 1824 198 117 1532 2000 1478 539 1982 125 1856 139 475 1338"
Prelude> map (map read) (map words $ lines test) :: [[Int]]
[[1224,926,1380,688,845,109,118,88,1275,1306,91,796,102,1361,27,995],[1928,2097,138,1824,198,117,1532,2000,1478,539,1982,125,1856,139,475,1338]]
You may need to take care of empty lines, but that's really simple.
import System.IO
readListOfLists :: Handle -> IO [[Int]]
readListOfLists handle = do
contents <- hGetContents handle
let ls :: [String]
ls = lines contents
ws :: [[String]]
ws= map words ls
res :: [[Int]]
res = map (map read) ws
return res;
or you can write the same code in one line:
readListOfLists :: Handle -> IO [[Int]]
readListOfLists = fmap (map (map read . words) . lines) . hGetContents
To use it:
do
handle <- openFile fileName ReadMode
table <- readListOfLists handle
hClose handle
print table
I'm trying to run the below script to get a list of Orgs and the amount of users each Org has:
#!/bin/bash
array=(293 182 177 12 85 51 325 225 40 169 357 329 243 349 291 295 22 279 16 69 219 299 301 331 91 281 285 59 283 341 45 289 95 61 77 13 14 201 43 343 223 28 171 26 233 47 303 367 369 339 257 305 353 245 213 87 345 2 71 199 24 179 259 37 35 237)
for i in "${array[#]}"; do
query=$(export MYSQL_PWD=MYPASS; mysql -e "SELECT COUNT(*) FROM Org.Users WHERE HomeOrgID=$i;")
echo "Org_$i:$query"
done
I expect the result to be a simple "Org:Number" list:
Org_1:150
Org_25:250
Org_17:64
Org_64:12
But the output is not displayed correctly. It does show part of the MySQL statement:
Org_293:COUNT(*)
1
Org_182:COUNT(*)
0
Org_177:COUNT(*)
8
Org_12:COUNT(*)
0
Org_85:COUNT(*)
1
How can I get the output to NOT display that "COUNT(*)" and display just a simple list?
Thanks in advance!
One quick hack : use bash arrays to store your output.
#!/bin/bash
array=(293 182 177 12 85 51 325 225 40 169 357 329 243 349 291 295 22 279 16 69 219 299 301 331 91 281 285 59 283 341 45 289 95 61 77 13 14 201 43 343 223 28 171 26 233 47 303 367 369 339 257 305 353 245 213 87 345 2 71 199 24 179 259 37 35 237)
for i in "${array[#]}"; do
# we store the result of the request as an array
query=($(export MYSQL_PWD=MYPASS; mysql -e "SELECT COUNT(*) FROM Org.Users WHERE HomeOrgID=$i;"))
# we echo the 2nd member of the array. ${query[0]} should contain 'count(*)'
echo "Org_$i:${query[1]}"
done
In a coding contest I have a programming task to find minimum or maximum from different arrays, and the final result to put it at the end of the URL (www.example.com/result).
I can't figure out what format are they expecting...
They gave this hint:
look at the resulting values and see if they could represent something familiar), at the end of the root of the URL of the page you're on (of course add a slash if needed)
Update
For the result of the problem, you need to figure out a way to convert those numbers to a "URL friendly form" value.
For example, a URL friendly value means a string, so you need a 'standard' way to convert each number to a character and use the resulting string to go to the next problem.
I tried the following formats 1:2:3:4 , 1_2_3_4 no chance.
The numbers are 100,126,114,85,82,121,54 .
So I need them formatted in an url friendly form whatever that would mean.
This is the coding challenge :
You are given an input file containing:
On the first line a positive integer N
On the following N lines there will be arrays of integers, of variable length, each integer value separated by a white space from the next value
The start of each array will only contain one of the following possible numbers: 1 or -1
To get to the next step you will have to calculate the minimum (if start value is -1) or maximum (if start value is 1) of the arrays in the input file and then put the result, in a more human and URL friendly form (hint: look at the resulting values and see if they could represent somehting familiar), at the end of the root of the URL of the page you're on (of course add a slash if needed). Also keep the code used to solve this problem!
Here is your input data:

I'm a complete novice when it comes to SQL, just getting started.
I need help writing a query to update values in my SQL table:
Two tables: Members, Chapters
Concerned with three columns in Chapters table: CHAP_NO, FA, FA2
i.e.
CHAP_NO FA FA2
111 1234567 2345689
222 2234567 4567899
333 3225545
444
555 2358878 4566665
666 4568799
777 4566878 1233666
888 1119998
999 3555879 6544799
etc. . .
Each value is a unique identifier
Concerned with two columns in Members table: MEMB_NO, CURR_CHAP
i.e.
MEMB_NO CURR_CHAP
1234567 665
5468787 664
4577789 122
4578767 233
7775666 588
4114748 787
etc. . .
Is it possible to automate an update based on if FA or FA2 is in Chapters table, update their CURR_CHAP value in the Members table from the CHAP_NO value?
From the above example data, I need MEMB_NO '1234567' to have his CURR_CHAP updated to '111' because he is listed as FA for CHAP_NO '111'
I really need to do this for similar MS SQL and MySQL databases if possible. If this can't be automated, I need help writing a query to manually update the Members table as exampled above with a 2 column manual update row of data:

I think this should work on both...
UPDATE
IGNORE Chapters,
Members
SET Members.CURR_CHAP = Chapters.CHAP_NO
WHERE Chapters.FA = Members.MEMB_NO
AND Chapters.FA != ''
AND Chapters.FA2 != ''
UPDATE members m
INNER JOIN chapters c on (m.memb_no = c.fa or m.memb_no=c.fa2)
SET m.curr_chap=c.chap_no
This query worked for me in MySql
update Members m
INNER JOIN chapters c
ON (m.memb_no=c.FA or m.memb_no=c.FA2)
set CURR_CHAP = c.CHAP_NO
I just reviewed this question but what I need is something quite different.
However, I have this table:
team_players_order
(team_id,
player_id,
ordering,
captain
)
The table stores a list of teams ids along with their players ids that belong to each team (each team could get 0-15 players). What I want to get is the teams that have a common players among them.
The list of teams I want to compare could be known (I have their ids)or unknown, then I might need to search the whole table and compare all teams. .
Here's a sample data for three teams:
team_id player_id ordering captain
117 134 0 N
117 55 1 N
117 97 2 N
117 215 3 N
117 165 4 N
117 221 5 N
117 163 6 N
117 128 7 N >> common player
117 180 8 N
117 96 9 N
117 162 10 N
117 88 11 N
117 229 12 N
117 91 13 N
117 105 14 N
-----------------------------------------------
124 88 0 N
124 165 1 N
124 92 2 N
124 130 3 N
124 47 4 N
124 221 5 N
124 30 6 N
124 223 7 N
124 105 8 Y
124 6 9 N
124 96 10 N
124 120 11 N
124 198 12 N
124 128 13 N >> common player
124 202 14 N
-----------------------------------------------
125 256 0 N
125 58 1 N
125 10 2 N
125 47 3 N
125 103 4 N
125 167 5 N
125 221 6 N
125 128 7 N >> common player
125 105 8 N
125 96 9 Y
125 180 10 N
125 210 11 N
125 229 12 N
125 30 13 N
125 33 14 N
As you can see, player 128 is common player among these three teams. I need to find other common players as well.
What I have tried so far is the following query which I guess is comparing each giving team with all other teams and get any common player that exists individually of each comparison.
SELECT
t1.team_id,
t1.player_id,
t2.team_id,
t2.player_id
FROM team_players_order AS t1
INNER JOIN team_players_order AS t2
ON (t1.team_id != t2.team_id
AND t1.player_id = t2.player_id)
WHERE t1.team_id IN(117,124,125)
AND t2.team_id IN(117,124,125)
ORDER BY t1.team_id, t2.team_id
which returns:
team_id player_id team_id player_id
117 221 124 221
117 88 124 88
117 96 124 96
117 105 124 105
117 128 124 128
117 165 124 165
117 180 125 180
117 221 125 221
117 229 125 229
117 96 125 96
117 105 125 105
117 128 125 128
124 128 117 128
124 165 117 165
124 221 117 221
124 88 117 88
124 96 117 96
124 105 117 105
124 128 125 128
124 30 125 30
124 221 125 221
124 47 125 47
124 96 125 96
124 105 125 105
125 128 117 128
125 180 117 180
125 221 117 221
125 229 117 229
125 96 117 96
125 105 117 105
125 128 124 128
125 221 124 221
125 30 124 30
125 47 124 47
125 96 124 96
125 105 124 105
But what I want is:
the players that exist in all giving teams (by their ids)
the player that exist in all teams.
n.b. the list of teams could reach to 100 once it's given.
HAVING is the solution
the player that exist in all teams
select team_id, player_id, count(*) nb from team_players_order
group by player_id
having nb > 1
the players that exist in all giving teams
select team_id, player_id, count(*) nb from team_players_order
where team_id in (124, 117)
group by player_id
having nb > 1
You can use "HAVING COUNT" in order to know which player is in multiple teams.
SELECT player_id FROM team_players GROUP BY team_id HAVING COUNT(team_id) > 1
And to list teams that have a player in other teams :
SELECT team_id FROM team_players GROUP BY team_id HAVING COUNT(player_id) > 1
Hope that helps !
