This image has padding at the bottom of it that I cannot seem to find to kill. I have used CSS Reset from Yahoo to see if that helped, and even removed all CSS to see if I can locate the problem.
Using Firebug, I tried a few on the fly methods of nullifying the padding, but nothing seems to work.
Can anyone else figure out what the problem may be?

Using this you can add router level middlewares to your resolvers in a much similar way like we do in express.
You can setup your resolver something like this :
```js
import Router from 'graphql-router-ware';
import { checkPermission } from '../helpers/userhalper';
import Controller from '../controllers/page';
const resolvers = {
Query: {
singlePage: Router(Controller.singlePage)
},
Mutation: {
createPage: Router(checkPermission,Controller.create),
updatePage: Router(checkPermission,Controller.update),
}
}
export default resolvers;
```
Followed by your middleware :
```js
// ....
export checkPermission=({ ctx },next)=>{
if(!ctx.user){
return next(new Error('Not logged in'));
// or throw new Error('Not logged in')
}
// some more permission checks....
return next();
};
// ....
```

select *

row_number() over (partition by SiteId, convert(date, datetime) order by (select null)) as seqnum

If performance is an issue, then a correlated subquery might have better performance:

select t.*
from t
where t.datetime = (select min(t2.datetime)

where t2.siteId = t.siteId and
t2.date >= convert(date, t.date) and
t2.date < dateadd(day, 1, convert(date, t2.date))

When I manually execute the batch file a cmd prompt flickers but it seams nothing happens as my CPU usage doesn't steadily change as it would if I were to use the 7zip GUI.

I am new to 7zip command line. I'm sure I am missing something crucial. When I manually execute the batch file a cmd prompt flickers but it seams nothing happens as my CPU usage doesn't steadily change as it would if I were to use the 7zip GUI. I believe the cmd prompt is flickering because it's started but there was a syntax error.
In the past I've used
```
for /d %%X in (*) do "c:\Program Files\7-Zip\7z.exe" a "%%X.7z" "%%X\"
```
to compress every folder within a current directory and it seamed to work nicely.
How can I specify Folders and Files to include in one archive using a batch.
Any tips will be greatly appreciated. | 2019/07/09 | [

I figured it out. Thanks for the support! After a bunch of reading and trial and error, I realized if the path of the source or destination includes a space: quotations are required. And if there is no space: don't include quotations. See the example above. Hope this helps others in the future.
Not to confuse, but I've added a password as well as hiding the file names before the password is entered. I do realize the password will be in the .bat but these archives will be transferred to other machines and the .bat will not be available to those in the future. | You can use text file containing a list of source paths as described [here](https://sevenzip.osdn.jp/chm/cmdline/syntax.htm).

] | Polish the stainless. Depending how long at maximum temperature it will tint pink then blue . If necessary it could be repolished. If it will have long exposure with no repolish, maybe a thin sheet of gold or platinum. Gold foil is old technology if there is no abrasion or other physical contact. I doubt there is existing technology for chrome plating of stainless. | There are a number of factors to consider here, namely: ability to coat and bond to the stainless steel, corrosion, abrasion resistance, maintenance, how dirty the plate will get, melting point and how heat is absorbed by the steel substrate.
If you want to reflect as much heat as possible, you would want a material with a low absorbance across a wide range of wavelengths.
Gold is a possibility because of its inert nature, ability to be plated on, melting point of about 1064C. Platinum would work too. Silver may tarnish but it depends on the environment it is exposed to. Problem with reflectors is that if they start getting corroded, scratched or dirty, their reflectivity drops over time. These metals have poor abrasion resistance, and may make them the subject of theft.
The disadvantage of a metal reflective coating on a metal substrate is that heat is conducted by your coating into the substrate, which brings us to an alternative solution.
The alternative to having a high thermal reflective coat, is to have a coating that is a poor thermal conductor but may not be such a good reflector. In which case your coating increases in temperature, re-emits the absorbed heat as a black body radiator but doesn't transmit the heat so well to the stainless steel substrate. Many poor thermal conductors (aerogel, ceramics) do not bond so well to steel and can not be easily made into thin layers or coatings. |

Here is the table I want to UPDATE on server 2:
```
(Stuff Id UNIQUEIDENTIFIER
, stuffname NVARCHAR(64))
```
I need to update it from server 1.
So I have been attempting this:
```
DECLARE @newstuff nvarchar(64)
SELECT @newstuff = 'new stuff'
UPDATE [server2].database2.dbo.Stuff
SET stuffname=@newstuff
WHERE stuffId='4893CD93-08B3-4981-851B-5DC972288290'
```
That takes 11 seconds. This next one using a literal runs in under 1 second
```
UPDATE [server2].database2.dbo.Stuff
SET stuffname='new stuff'
WHERE stuffId='4893CD93-08B3-4981-851B-5DC972288290'
```
I have compared the actual execution plans. The slow one is doing a Remote scan that takes 100% of the cost, plus 5 other steps (filter, table spool, compute scalar, remote update, update). The fast one just does the UPDATE and Remote Query steps. I need to use variables, so I need a way to force it to do the whole query remotely.
I have tried using OPTION(RECOMPILE) but server1 is using SQL Server 2005. server2 is using SQL Server 2012. I can't change the database structure at all on server2 without serious problems. I am not having any authentication problems. I have tried aliasing the table when updating it.
I have also tried using Openquery. When I put the id filter within the query string, it gets back down to under 1 second:
```
UPDATE OPENQUERY([server2], 'select stuffname, stuffid from database2.dbo.stufftable where contactid=''4CA1D489-9221-E511-A441-005056C00008''')
SET stuffname = @newstuff
```
But I need that id to be a variable as well, and that open query does not take variables (<https://msdn.microsoft.com/en-CA/library/ms188427.aspx>). I tried running Openquery with the id filter outside the query, but that runs in 4 seconds. It's better than 11, but not great:

UPDATE OPENQUERY([server2],'select stuffname, stuffid from database2.dbo.stufftable')
set stuffname=@newstuff
where contactid='4CA1D489-9221-E511-A441-005056C00008'
```
Of course, I run openquery using exec(@sql), but I really don't want to go that way. I could do the whole update statement that way using literals and not even use OPENQUERY and get the same sort of result anyway.

] | I believe your problem is related to the permissions that you are running the connection to the LINKED server with.
there are links where this case has been explained and I have had similar experiences.
here are a couple of links:
[OPENQUERY when executing linked server queries in SQL Server](http://blogs.msdn.com/b/sqlsakthi/archive/2011/05/09/best-performer-distributed-query-four-part-or-openquery-when-executing-linked-server-queries-in-sql-server.aspx)
[TOP 3 PERFORMANCE KILLERS FOR LINKED SERVER QUERIES](http://thomaslarock.com/2013/05/top-3-performance-killers-for-linked-server-queries/)
I will post my solution below.
I have set up an environment to test your solution.
my server2 is sql server 2005
my server1 is sql server 2012.
On server2 I have created and populated the stuff table in the following way:
I use a database called tablebackups with a specific naming convention but I am sure you can understand:
The result is a table with a clustered primary key on a identity field and another field for the update. this table in my example has 100,000 records.
```
select @@version
--Microsoft SQL Server 2005 - 9.00.5000.00 (Intel X86)
--Dec 10 2010 10:56:29
--Copyright (c) 1988-2005 Microsoft Corporation
--Standard Edition on Windows NT 5.2 (Build 3790: Service Pack 2)
use tablebackups
go
CREATE TABLE dbo._MM_201504710_stuff ( Id UNIQUEIDENTIFIER
, stuffname NVARCHAR(64)
)
ALTER TABLE dbo._MM_201504710_stuff ADD CONSTRAINT [PK_Stuff] UNIQUE CLUSTERED ( ID );
-- add 100,000 records to the table so that we can have an idea of execution
SET NOCOUNT ON
insert into dbo._MM_201504710_stuff values (NewID(),'Radhe Radhe')
GO 100000 -- 100,000
SET NOCOUNT OFF
--this took 19:38
--just to test
SELECT TOP 100 * FROM dbo._MM_201504710_stuff
--18D4BDEA-6226-47E1-94DB-00402A29798F
DECLARE @newstuff nvarchar(64)
SELECT @newstuff = 'new stuff'
UPDATE dbo._MM_201504710_stuff
SET stuffname=@newstuff
WHERE Id='18D4BDEA-6226-47E1-94DB-00402A29798F'
UPDATE dbo._MM_201504710_stuff
SET stuffname='new stuff'
WHERE Id='18D4BDEA-6226-47E1-94DB-00402A29798F'
```
the execution plans of these updates are very similar and are not an issue.
As you can see on the picture below.
Before going to server1 I double check when the statistics of my stuff table have been updated, because this will influence the query plan generation.
Just to be sure.
Then I go to server1.
NO, Before I go to server1, on server2 I have this sql login with the following permissions:
I call it "monitor"
and for the permissions of "monitor"
I use this select:
```
SELECT p.[name], sp.permission_name, p.type_desc AS loginType FROM sys.server_principals p
JOIN sys.server_permissions Sp
ON p.principal_id = sp.grantee_principal_id WHERE sp.class = 100
```
That shows me these permissions:
NOW on server1 I have a linked server to server2 (sqlsalon1.dev.boden.local)
and this LINKED server use "monitor" to connect to server2.
as you could see above, this monitor sql user has all the required permissions to see and update the statistics and therefore we can use the best plan even when running remote transactions.
ON SERVER1:
I connect to server2 using the following linked server:
running these scripts (less than a sec)
```
-- just to test
select top 100 *
from [SQLSALON1.dev.boden.local].tablebackups.dbo._MM_201504710_stuff
--first update
UPDATE [SQLSALON1.dev.boden.local].tablebackups.dbo._MM_201504710_stuff

quick as a bolt
 | I would do it like this. Rather than sending the actual `UPDATE` query to execute to server2, I would make a stored procedure on server2 with the necessary parameters and call it from server1.
Inside the stored procedure you can tweak the query as needed using all capabilities of server2 to make it run fast (like `OPTION(RECOMPILE)`, for example).
Besides, having explicit stored procedures like this defines an interface how two systems interact, which is good on its own. |
31,212,087 | I've searched everywhere for this situation and can't find a solution **except for Dynamic SQL, which I don't want to use**.
Here is the table I want to UPDATE on server 2:
```
(Stuff Id UNIQUEIDENTIFIER
, stuffname NVARCHAR(64))
```
I need to update it from server 1.
So I have been attempting this:
```
DECLARE @newstuff nvarchar(64)
SELECT @newstuff = 'new stuff'
UPDATE [server2].database2.dbo.Stuff
SET stuffname=@newstuff
WHERE stuffId='4893CD93-08B3-4981-851B-5DC972288290'
```
That takes 11 seconds. This next one using a literal runs in under 1 second
```
UPDATE [server2].database2.dbo.Stuff
SET stuffname='new stuff'
WHERE stuffId='4893CD93-08B3-4981-851B-5DC972288290'
```
I have compared the actual execution plans. The slow one is doing a Remote scan that takes 100% of the cost, plus 5 other steps (filter, table spool, compute scalar, remote update, update). The fast one just does the UPDATE and Remote Query steps. I need to use variables, so I need a way to force it to do the whole query remotely.
I have tried using OPTION(RECOMPILE) but server1 is using SQL Server 2005. server2 is using SQL Server 2012. I can't change the database structure at all on server2 without serious problems. I am not having any authentication problems. I have tried aliasing the table when updating it.
I have also tried using Openquery. When I put the id filter within the query string, it gets back down to under 1 second:
```
UPDATE OPENQUERY([server2], 'select stuffname, stuffid from database2.dbo.stufftable where contactid=''4CA1D489-9221-E511-A441-005056C00008''')
SET stuffname = @newstuff
```
But I need that id to be a variable as well, and that open query does not take variables (<https://msdn.microsoft.com/en-CA/library/ms188427.aspx>). I tried running Openquery with the id filter outside the query, but that runs in 4 seconds. It's better than 11, but not great:
```
UPDATE OPENQUERY([server2],'select stuffname, stuffid from database2.dbo.stufftable')
set stuffname=@newstuff
where contactid='4CA1D489-9221-E511-A441-005056C00008'
```
Of course, I run openquery using exec(@sql), but I really don't want to go that way. I could do the whole update statement that way using literals and not even use OPENQUERY and get the same sort of result anyway.
Is there any way for me to get this performance fixed without using exec(@sql)? | 2015/07/03 | [

[TOP 3 PERFORMANCE KILLERS FOR LINKED SERVER QUERIES](http://thomaslarock.com/2013/05/top-3-performance-killers-for-linked-server-queries/)
I will post my solution below.
I have set up an environment to test your solution.
my server2 is sql server 2005
my server1 is sql server 2012.
On server2 I have created and populated the stuff table in the following way:
I use a database called tablebackups with a specific naming convention but I am sure you can understand:
The result is a table with a clustered primary key on a identity field and another field for the update. this table in my example has 100,000 records.

```
the execution plans of these updates are very similar and are not an issue.
As you can see on the picture below.
Before going to server1 I double check when the statistics of my stuff table have been updated, because this will influence the query plan generation.
Just to be sure.
Then I go to server1.
NO, Before I go to server1, on server2 I have this sql login with the following permissions:
I call it "monitor"
and for the permissions of "monitor"
I use this select:
```
SELECT p.[name], sp.permission_name, p.type_desc AS loginType FROM sys.server_principals p
JOIN sys.server_permissions Sp
ON p.principal_id = sp.grantee_principal_id WHERE sp.class = 100
```
That shows me these permissions:
NOW on server1 I have a linked server to server2 (sqlsalon1.dev.boden.local)
and this LINKED server use "monitor" to connect to server2.
as you could see above, this monitor sql user has all the required permissions to see and update the statistics and therefore we can use the best plan even when running remote transactions.
ON SERVER1:
I connect to server2 using the following linked server:
running these scripts (less than a sec)
```
-- just to test

and this will update the row, with or without a variable, in the same way.
quick as a bolt
 | Perhaps the issue has to do with the unique identifier column. Have you tried:
On server2 define the following stored procedure:
```
CREATE PROCEDURE updateStuff( @newstuff nvarchar(30), @stuffid varchar(36))
AS
UPDATE Stuff
SET stuffname=@newstuff
WHERE stuffId=convert(uniqueidentifier, @stuffid))
```
The from server 1 invoke:
exec server2.database2.updatestuff N'New stuff', '4893CD93-08B3-4981-851B-5DC972288290'
OLD suggestion:
Declare @stuffid uniqueidentifier
Set @stuffid = convert(uniqueidentifier,='4893CD93-08B3-4981-851B-5DC972288290')
UPDATE [server2].database2.dbo.Stuff
SET stuffname=@newstuff
WHERE stuffId=@stuffid |
31,212,087 | I've searched everywhere for this situation and can't find a solution **except for Dynamic SQL, which I don't want to use**.
Here is the table I want to UPDATE on server 2:
```
(Stuff Id UNIQUEIDENTIFIER
, stuffname NVARCHAR(64))
```
I need to update it from server 1.
So I have been attempting this:
```
DECLARE @newstuff nvarchar(64)
SELECT @newstuff = 'new stuff'
UPDATE [server2].database2.dbo.Stuff
SET stuffname=@newstuff
WHERE stuffId='4893CD93-08B3-4981-851B-5DC972288290'
```
That takes 11 seconds. This next one using a literal runs in under 1 second
```
UPDATE [server2].database2.dbo.Stuff
SET stuffname='new stuff'
WHERE stuffId='4893CD93-08B3-4981-851B-5DC972288290'
```
I have compared the actual execution plans. The slow one is doing a Remote scan that takes 100% of the cost, plus 5 other steps (filter, table spool, compute scalar, remote update, update). The fast one just does the UPDATE and Remote Query steps. I need to use variables, so I need a way to force it to do the whole query remotely.
I have tried using OPTION(RECOMPILE) but server1 is using SQL Server 2005. server2 is using SQL Server 2012. I can't change the database structure at all on server2 without serious problems. I am not having any authentication problems. I have tried aliasing the table when updating it.
I have also tried using Openquery. When I put the id filter within the query string, it gets back down to under 1 second:
```
UPDATE OPENQUERY([server2], 'select stuffname, stuffid from database2.dbo.stufftable where contactid=''4CA1D489-9221-E511-A441-005056C00008''')
SET stuffname = @newstuff
```
But I need that id to be a variable as well, and that open query does not take variables (<https://msdn.microsoft.com/en-CA/library/ms188427.aspx>). I tried running Openquery with the id filter outside the query, but that runs in 4 seconds. It's better than 11, but not great:
```
UPDATE OPENQUERY([server2],'select stuffname, stuffid from database2.dbo.stufftable')
set stuffname=@newstuff
where contactid='4CA1D489-9221-E511-A441-005056C00008'
```
Of course, I run openquery using exec(@sql), but I really don't want to go that way. I could do the whole update statement that way using literals and not even use OPENQUERY and get the same sort of result anyway.
Is there any way for me to get this performance fixed without using exec(@sql)? | 2015/07/03 | [

] | I believe your problem is related to the permissions that you are running the connection to the LINKED server with.
there are links where this case has been explained and I have had similar experiences.
here are a couple of links:
[OPENQUERY when executing linked server queries in SQL Server](http://blogs.msdn.com/b/sqlsakthi/archive/2011/05/09/best-performer-distributed-query-four-part-or-openquery-when-executing-linked-server-queries-in-sql-server.aspx)
[TOP 3 PERFORMANCE KILLERS FOR LINKED SERVER QUERIES](http://thomaslarock.com/2013/05/top-3-performance-killers-for-linked-server-queries/)
I will post my solution below.
I have set up an environment to test your solution.
my server2 is sql server 2005
my server1 is sql server 2012.
On server2 I have created and populated the stuff table in the following way:
I use a database called tablebackups with a specific naming convention but I am sure you can understand:
The result is a table with a clustered primary key on a identity field and another field for the update. this table in my example has 100,000 records.
```

SET stuffname='new stuff'
WHERE Id='18D4BDEA-6226-47E1-94DB-00402A29798F'
```
the execution plans of these updates are very similar and are not an issue.
As you can see on the picture below.
Before going to server1 I double check when the statistics of my stuff table have been updated, because this will influence the query plan generation.
Just to be sure.
Then I go to server1.
NO, Before I go to server1, on server2 I have this sql login with the following permissions:
I call it "monitor"
and for the permissions of "monitor"
I use this select:
```
SELECT p.[name], sp.permission_name, p.type_desc AS loginType FROM sys.server_principals p
JOIN sys.server_permissions Sp
ON p.principal_id = sp.grantee_principal_id WHERE sp.class = 100
```
That shows me these permissions:
NOW on server1 I have a linked server to server2 (sqlsalon1.dev.boden.local)
and this LINKED server use "monitor" to connect to server2.
as you could see above, this monitor sql user has all the required permissions to see and update the statistics and therefore we can use the best plan even when running remote transactions.
ON SERVER1:
I connect to server2 using the following linked server:
running these scripts (less than a sec)
```
-- just to test
select top 100 *
from [SQLSALON1.dev.boden.local].tablebackups.dbo._MM_201504710_stuff
--first update
UPDATE [SQLSALON1.dev.boden.local].tablebackups.dbo._MM_201504710_stuff

SELECT @newstuff = 'new stuff'

SET stuffname=@newstuff
WHERE Id='18D4BDEA-6226-47E1-94DB-00402A29798F'
```
I get this query plan:
So, double check the permissions on the linked server account, if you copy mine I believe your problem will be solved, since this is working here, unless there is something else different, and in that case, please let me know, I will try to tackle it further.

] | You could change your array to contain functions instead of strings like this:
```
Func<string>[] mCalls = { c.get1, c.get2, c.get3...};
```
And then use it this way:
```
string c2 = mCalls[1]();
```
But note that this way *every* access is a method call. I'm not sure what you are really trying to achieve, there may be better overall designs than this approach. | What you could do is loop thorugh with reflection and get all methods from the class and from here you can get a list of method names. With this list you can assign to an array or run the methods by name or whatever. You can also filter the list to get your specific method names only:
```
var methodNames = typeof(MyClass).GetMethods(BindingFlags.Public | BindingFlags.Static)
.Select(x => x.Name)
.Distinct()
.OrderBy(x => x);
```
To call the methods:
```
foreach(var method in methodNames)
{
typeof(MyClass).GetMethod(method).Invoke(t, new[] { "world" });
}
``` |
36,313,122 | In C#, I have a string array that I have written full full of "getter" method calls. They call methods in another class so that the array is populated with the needed strings. It looks something like this:
```
string[] mCalls = {c.get1(), c.get2(), c.get3()};
```
I'm sure this situation could apply to any program. However, in my program the variables these methods return are initially set with the string `"Unchecked"` - thus filling this example array with Unchecked 3 times. As my program goes on and things are checked, the values of the string variables get changed within the class they're in. I've been simply re-calling the getter methods at appropriate times to change what's in my array, like this:
```
mCalls[0] = c.get1();
mCalls[1] = c.get2();
mCalls[2] = c.get3();

So is it possible to connect these two akku packs in series to reach this or are there any critical issues, that can occur?

] | You would not be connecting two Li-ion batteries in series. Li-ion batteries have a 3.6V output not 5V.
Whether they are in series is less of an issue than the current draw. You should be fine as long as you do not discharge the batteries too fast. That should not be an issue because li-ion batteries are very regulated, must pass safety standard tests, and there is likely a current limit on the output.
Many inexpensive off brand li-ion battery packs are not li-ion but NiMH. If the battery packs were shipped UPS, FedEx, or any way other than strictly ground, they are likely not Li-ion. UPS and FedEx will not ship Li-ion batteries or battery packs unless they are packaged with a device that uses the batteries. | There shouldn't be problem as long as batteries provide same voltage. If one battery in chain is weak, that would stress it, would cause unexpected voltage and current drop. Thus you should not connect batteries of different capacity or "age" for that reason, because one would discharge at different rate. Large "chains" of packs may heat too much, providing reason to failure.
But you shouldn't not probably connect "regulated" battery packs (and 5V-6V packs may come in this way) this way, they include electronics that may not work with that setup. IF it is rated at unusual nominal voltage it's either a lie, or there is voltage converter inside pack |

Which means basically "take all of the parameters and pass them to `event.execute`" so you are passing an undetermined amount of parameters (depending on the event type) and the `client` is not guaranteed to be the second one as you expect.
To provide some more details, the Discord client can send multiple different types of events, and every type of event provides a different amount of parameters in the callback. In other words by writing this: `(...args) => event.execute(...args,client)` you are retrieving an unknown amount of parameters, and passing them all to the `event.execute` function, so the position of the `client` parameter could vary, and it's not necessarily the second one as you expect in the function signature: `async execute(message, client) {`
You could either retrieve only the first parameter if you don't need others, like this:
```
client.once(event.name, arg => event.execute(arg, client));
```
And if you absolutely need all of the parameters, pass the client as first so it never moves, like this:
```
client.once(event.name, (...args) => event.execute(client, ...args));
```
Also adapt the `execute` signature:
```
async execute(client, ...args) {
``` | ```
module.exports = {
name: "eg",
description: "not ready",
category: "test",
execute(message, args, client){
const channel = client.channels.cache.get('853031094054944798');
channel.send('test');
}
}
```
it was the addition of args, before client that fixed it.
so in this example:
```
const { prefix } = require("../config.json");
module.exports = {
name: "report",
description: "This command allows you to report a user for smurfing.",
catefory: "misc",
usage: "To report a player, do $report <discord name> <reason>",
async execute(message, args, client) {
const args = message.content.slice(1).trim().split(/ +/);
const offender = message.mentions.users.first();
if (args.length < 2 || !offender.username) {
return message.reply('Please mention the user you want to report and specify a reason.');
}
const reason = args.slice(2).join(' ');
client.channels.cache.get('xxxxx').send(offender);
message.reply("You reported"${offender} for reason: ${reason}`);
}
}
```
It would be this. |
14,505,405 | I know that it is not recommended to block in the `receive` method of an actor, but I believe it can be done (as long as it is not done in too many actors at once).
[This post](http://letitcrash.com/post/29773618510/an-akka-2-terminator) suggests blocking in `preStart` as one way to solve a problem, so presumably blocking in `preStart` is safe.
However, I tried to block in `preRestart` (not `preStart`) and everything seemed to just hang - no more messages were logged as received.

167,110 | With pretty much every circuit in a home needing one of the two types of protection (AFCI or GFCI), why don't all new homes have combination breakers installed just to be safe? Would it hurt anything using both types of protections for every breaker? I know that based on code we technically don't NEED both types of protection, but is it necessarily a bad thing to have?

] | Sure, go for it
---------------
There's no basic problem with what you propose. Feel free to put CAFCIs in all breaker positions.
You may have a problem finding AFCIs larger than 20/30 amps, and you may have trouble finding 2-pole AFCIs in some cases. In this instance, for equivalent protection where AFCI is not mandated, simply run those circuits in metal conduit, e.g. EMT/THHN wire. This will protect the wire, not the appliances. | AFCI breakers (which NEC now requires on new houses) make a lot of sense. Issues with wires going bad are pretty rare and there's not too many things outside that that can trip one. The likelihood of a nuisance AFCI trip is fairly low.
AFCIs also protect against hidden dangers. Arcing events can happen in hidden locations (like junction boxes) and you might not realize it until the fire department figures out what burned down your house.
GFCIs, however, are much more prone to nuisance trips. Imagine you dropped your hair dryer in a sink. Most GFCIs are next to the point where a grounding event can happen (i.e. inside an outlet). This makes them easy to diagnose and reset. If that GFCI is on the breaker, however, that may not be obvious at all.
GFCI might also be on something you don't want to be subject to nuisance trips. A kitchen refrigerator might get its own circuit, but what about a freezer or mini-fridge?
The final nail in the coffin here is cost. You're going to add a lot of cost to mitigate the small chance that somewhere not already covered by GFCI requirements is going to experience a grounding event. |

Output for same, but with FontFamily "Monospace":
Note that the final results are shown in MM's internal font, not in the font being sorted. Hence, you see the differences in the font chosen reflected in the sort. The CDF link shows both, though, for the completists.

I'm new to this site, so I am unsure how input is normally read for Javascript answers. I assume input is contained in a variable named `s`. If this is not OK, I will update the answer and the char count.

23,362 | Your program must take as input a line of characters, like this:
```
@+.0
```
And output the characters sorted by how dark they are, like this:
```
.+0@
```
Requirements:
* You must use a monospaced font for darkness detection.
* You must find out how many pixels each character takes up. You must actually draw the character and count pixels, i.e. you can't just hardcode pixel amounts.
+ As a more concrete rule: if you switched fonts, your program should still work. Furthermore, your program should be able to switch fonts by simply changing a variable or value or string in the code.
* If you use antialiasing, you must count pixels as percentages of a fully black pixel. For example, an `rgb(32, 32, 32)` pixel will count as 1/8 of a full pixel. Disregard this rule if your characters are not antialiased.
* After counting pixels, you must sort the characters by the amount of pixels, and output them in order.

**Update:** Replaced OCR A with Menlo because I realized that on OSX the OCR A font family name is actually OCR A Std. So I was sorting a default font instead of the real deal. Menlo is also monospaced with the same byte count, so no net gain or loss.
I've put up a [hosted CDF export of the notebook](http://www.jonathanvanmatre.com/blog/mathematica-notebooks/), so you can see the code in action if you wish. I'm still figuring out how to add some interactivity to web-hosted CDFs, so for now it's just static.
```m
c=Characters@s;Last/@Sort[Transpose@{Total[1-#&/@ImageData@Rasterize@Style[#,FontFamily->"Menlo"],3]&/@c,c}]
```
Output for `s = FromCharacterCode /@ Range[33, 135];` with "Courier"
Output for same, but with FontFamily "Monospace":
Note that the final results are shown in MM's internal font, not in the font being sorted. Hence, you see the differences in the font chosen reflected in the sort. The CDF link shows both, though, for the completists.
Ungolfed code:
```m
s = FromCharacterCode /@ Range[33, 135];
c = Characters@s;

Here's something completely different, just for fun. As most fonts are vector anyway, 'counting pixels' is a little odd, isn't it. Calculating glyph shape area, while being correct way, is not that easy. An alternative can be scanning a rectangle and counting 'hits' when a point is inside a glyph shape, and Postscript has operators for this kind of checks. Though, true, scanning and insideness-testing is just a weird way of counting pixels.

23,362 | Your program must take as input a line of characters, like this:
```
@+.0
```
And output the characters sorted by how dark they are, like this:
```

Requirements:
* You must use a monospaced font for darkness detection.
* You must find out how many pixels each character takes up. You must actually draw the character and count pixels, i.e. you can't just hardcode pixel amounts.
+ As a more concrete rule: if you switched fonts, your program should still work. Furthermore, your program should be able to switch fonts by simply changing a variable or value or string in the code.
* If you use antialiasing, you must count pixels as percentages of a fully black pixel. For example, an `rgb(32, 32, 32)` pixel will count as 1/8 of a full pixel. Disregard this rule if your characters are not antialiased.
* After counting pixels, you must sort the characters by the amount of pixels, and output them in order.

```
SCREEN 1
DIM a(255)
FOR i = 32 TO 255
CLS
PRINT CHR$(i);
FOR p = 0 TO 64
a(i) = a(i) + POINT(p MOD 8, p \ 8)
NEXT p
NEXT i
FOR p = 0 TO 96
FOR i = 32 TO 255
IF a(i) = p THEN PRINT CHR$(i);
NEXT i
NEXT p
```
I did this for fun, so it's technically non-compliant to the rules in one way. It doesn't take a list of characters, but instead prints all characters from 32-255 and uses that instead. If you really want to see a version which complies with this rule, please tell me.
It also fails another technicality: "Furthermore, your program should be able to switch fonts by simply changing a variable or value or string in the code." There is no easy way to do this from within QBasic. However, the program will of course work fine with any codepage of your choosing.
Lastly, I could squeeze away a few characters (mostly whitespace that the QBasic IDE helpfully inserts,) but it's probably not worth it since this answer stands no chance of winning anyway.

```
Usage:
```
import java.awt.geom.*;
import java.util.*;
public class F {
public static void main(String[]args){
List<Character> s = new ArrayList<Character>(0);
s.add('@');
s.add('+');
s.add('.');
s.add('0');
n("Calibri", s);
System.out.println(s);
}
static void n(final String f,List<Character> s){
Collections.sort(s,new Comparator<Character>(){
public int compare(Character a,Character b){
return d(f,""+a) - d(f,""+b);
}
});
}
static int d(String f,String s){
int i=0;
PathIterator p=new java.awt.Font(f,0,12).createGlyphVector(((java.awt.Graphics2D)new java.awt.image.BufferedImage(8,8,2).getGraphics()).getFontRenderContext(),s).getGlyphOutline(0).getPathIterator(AffineTransform.getRotateInstance(0.0, 0.0));
while(!p.isDone()){
i+=p.currentSegment(new double[99])/2;
p.next();
}
return i;
}
}
```
This setup results in:
```
[., +, 0, @]
```
---
The only line here that needs explanation:
```
PathIterator p=new java.awt.Font(f,0,12).createGlyphVector(((java.awt.Graphics2D)new java.awt.image.BufferedImage(8,8,2).getGraphics()).getFontRenderContext(),s).getGlyphOutline(0).getPathIterator(AffineTransform.getRotateInstance(0.0, 0.0));
```
* Initialize the 12pt font object with the passed font.
* Create a new BufferedImage obejct to create a Graphics2D object linked to a GraphicsContext.
* Get the font rendering context of the 2D graphics context for the string s.
* Get the first glyph (only glyph) in the string.
* Get the path iterator (list of points).
Then this final piece brings it together...
```
while(!p.isDone()){
i+=p.currentSegment(new double[99])/2;
p.next();
}
```
By iterating through all points and summing count of points. This density information is passed back up to the comparator and is used for sorting. |

57,123,043 | Im working with Microsoft Dynamics 365 Business Central. (ERP Software).
Im attempting to create build agents on my local server to set up Continious Integration with my projects.
On the buildserver i am running Docker Enterprise on Windows 2019.
When i spin up my dockeragent to facilitate the builds im experiencing an issue.
The dockeragent is asked by my CI flow to spin up another docker container called navcontainerhelper which is basically a docker container that contains the Business Central environment to build my application on.
However the navcontainerhelper doesnt know the docker commands since it doesnt include docker.
Ive researched and found that mounting the docker socket with -v is the way to do this however i cant seem to get that working.
When i create the agent i am using the following command:
```
docker run -v /var/run/docker.sock:/var/run/docker.sock -ti dockeragent:latest -e AZP_URL=<My azure url> -e AZP_TOKEN=<my azure token) -e AZP_AGENT_NAME=<my builder agent name>
```
when i attempt to execute this i get the following command which leads me to the mentioned conclusion.
```
docker : C:\Program Files\docker\docker.exe: Error response from daemon: invalid volume specification: '/var/run/docker.sock:/var/run/docker.sock'.
At C:\dockeragent\StartAgents.ps1:1 char:1

+ CategoryInfo : NotSpecified: (C:\Program File...n/docker.sock'.:String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError
See 'C:\Program Files\docker\docker.exe run --help'.
```
Could someone give me a pointer as to what i am doing wrong?
I have changed the script to use the named pipes instead for windows. it now mounts like this:
```
docker run -e AZP_URL=<My azure url> -e AZP_TOKEN=<my azure token) -e AZP_AGENT_NAME=<my builder agent name> -v \\.\pipe\docker_engine:\\.\pipe\docker_engine dockeragent:latest
```
However the container still refuses to recognize my docker command:
```
New-NavContainer : The term 'docker' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

```
-v \.\pipe\docker_engine:\\.\pipe\docker_engine

and to install the docker client into the container so it can talk to the docker engine | I was having trouble with the install, so I used one of the docker provided windows images from [docker hub](https://hub.docker.com/_/docker) as my base image instead of a microsoft one.

In this particular case, `AInt` derives `Num`. This means that `AInt` is an instance of `Num` using the same code as `Int` (with everything wrapped in `A` constructors as appropriate). This includes `Int`'s `fromInteger` function.
The `fromInteger` function is defined in terms of `Int`'s `fromInteger`, looking something like this:
```
fromInteger i = A (fromInteger i)
```
Since `0` is polymorphic--it has the type `0 :: Num a => a`--it's a valid constant for *any* type in `Num`. Thanks to the newtype deriving, this includes `AInt`, using the `fromInteger` function above. This means there is really no difference between `0 :: AInt` an `A 0 :: AInt`. | Numeric literals like `0` are overloaded and have the type `0 :: Num a => a`, which means that they can be any type for which there is a `Num` instance, depending on the context. This happens via the `fromInteger` function in the `Num` type class, so when you type `0` it is treated as if you'd written `fromInteger 0`.
By using `GeneralizedNewtypeDeriving`, GHC has (effectively1) written a `Num` instance for your class looking something like this:
```
instance Num AInt where
fromInteger n = A (fromInteger n)
...
```
So when you write `0 :: AInt`, this expands to `fromInteger 0 :: AInt` which is (by the definition above) equal to `A (fromInteger 0)` which is the same as if you had written `A 0`.
1 `GeneralizedNewtypeDeriving` doesn't actually write a new intance. It just performs the necessary casts to use the existing one. |
386,675 | Let $A\_j,j\in\mathbb Z^+$ be finite sets with at least two distinct elements.
How to show that $\prod\_{j=1}^\infty A\_j$ is uncountable? | 2013/05/09 | [

] | **Hint:**
Replace each $A\_j$ by $B\_j=\{0,\ldots,n-1\}$, where $n=|A\_j|$, using the axiom of choice. Now we have:
$$\left|\prod\_{j\in\Bbb N}\{0,1\}\right|\leq\left|\prod\_{j\in\Bbb N}B\_j\right|=\left|\prod\_{j\in\Bbb N}A\_j\right|.$$
You can bound this from the right by the product of copies of $\Bbb N$ and calculate the exact cardinality too. I am leaving the details for you.
Do note, the axiom of choice is essential and it is consistent that there are families of finite sets whose product is empty, and thus countable. | Identify a subset of each set with {0,1} using AC, and map the corresponding subset of the product onto binary expansions of reals in the interval [0,1], hence uncountable. |

My web.config has `<authentication mode="Windows" />` and `<identity impersonate="true"/>`
My goal is that the users won't have to log in - that fact that they are logged into our network (and the fact that the site is not on an external IP) is enough authentication. I would just like to know who the user is in order to track changes they make, etc. | 2009/08/12 | [

] | With `<authentication mode="Windows"/>` in your application and Anonymous access enabled in IIS, you will see the following results:
```
System.Environment.UserName: Computer Name
Page.User.Identity.Name: Blank
System.Security.Principal.WindowsIdentity.GetCurrent().Name: Computer Name
```
With `<authentication mode="Windows"/>` in your application, and ‘Anonymous access’ disabled and only ‘Integrated Windows Authentication’ in IIS, you will see the following results:
```
System.Environment.UserName: ASPNET (user account used to run ASP.NET service)
Page.User.Identity.Name: Domain\ Windows Account Name
System.Security.Principal.WindowsIdentity.GetCurrent().Name: Computer Name\ASPNET
```
With `<authentication mode="Windows"/>` and `<identity impersonate ="true"/>` in your application, and ‘Anonymous access’ disabled and only ‘Integrated Windows Authentication’ in IIS, you will see the following results:
```
System.Environment.UserName: Windows Account Name
Page.User.Identity.Name: Domain\ Windows Account Name
System.Security.Principal.WindowsIdentity.GetCurrent().Name: Domain\ Windows Account Name
``` | I just wanted to post my fix, because no one else had said anything about it.
I was having the same issue when I published the site to the server, but not on my local. All the settings were the same. However, in IIS the "Default Website" had never been turned off. It was running and intercepting traffic, even though there was no site associated with it. Anonymous Authentication was turned on in the default, but turned off in my website running under port 80. It didn't seem to matter that my site had it turned off... since the default was turned on it was turned on for all traffic to port 80.
Disabling the default web fixed the issue. Also changing the port to 8080 works.
I hope this helps someone. |

* The first LEFT JOIN is linking programs to entities on a UID
* The first INNER JOIN is linking programs to a subquery that gets statistics for those programs, by linking on a UID
* The subquery (that gets the StatsForDistributorClubs subset) is doing a grouping on UID columns

226,599 | Using the following code, I make a simple graph that is exported to pdf:
```
format = AxesStyle -> {{Thickness[.01], Arrowheads[{0.0, 0.05}]}, { Arrowheads[{0.0, 0.05}]} }
graph = ListLinePlot[Table[{t, 2*t}, {t, 0, 100}], format, AspectRatio -> .2]

```
When I look at the graph, it cuts of the end of one of the arrows:
[](https://i.stack.imgur.com/lVJwa.png)
The y axis is ok - but the x axis is not. The end of the arrow has been clipped. It seems to be related to increasing the thickness of the axis.
For what its worth, the in-notebook display of the graph has complete arrows. It is only the exported version that is clipped.
I want both axes thick, and I want the whole arrow, and I want it in PDF. How to do this?
Please note that it didn't have this problem in Mathematica 11.3; it is only after I upgraded that this problem has arisen. I'm using 12.1
Edit: The reason I want it in pdf is not because I like the file format, but because I want it in a vector graphic that works with Latex. The output should have the resolution of a high quality vector graphic, without the arrow chopped. | 2020/07/27 | [

] | The cut off in the head of the arrow appeared due to the assigned thickness of the axes, to check this we can change the position of the arrow and examine it closely as follow:
```
format = AxesStyle -> {{Thickness[0.02],
Arrowheads[{{0.09, 0.8}}]}, {Arrowheads[{0.0, 0.05}]}};

[](https://i.stack.imgur.com/rK0gw.png)
I used a pdf editor to check the head of the arrow, and this cut off is increased with increasing the thickness of the axes. So, the simple solution is to avoid assign specific thickness and instead impose it like this-:)
```
format = AxesStyle -> {{Arrowheads[{0.0, 0.05}]}, {Arrowheads[{0.0,
0.05}]}};

The main problem is to use the right font. Mathematica is publication-ready, but are all the other programs especially for publication-ready for their task. The main problem is to determine the operating system one is on.
Otherwise, the Mathematica documentation is genial: [PDF](http://reference.wolfram.com/language/ref/format/PDF.html).
You are to work publication-ready responsible to match the fonts. That is true on all operating systems and everywhere. So match the font Mathematica uses in the graphics to the ones available to the pdf display program set on the local machine.
[`Scaled`](http://reference.wolfram.com/language/ref/Scaled.html) is really nice built-in otherwise.
There are features like pdf font embedding.
Another workaround is to export the graphics to SVG and convert the svg externally to pdf.
[SVG](http://reference.wolfram.com/language/ref/format/SVG.html) is mightier in Mathematica.

And correct smaller deviation from the intent by hand after some experience is accumulated.
Converting SVG to PDf is safe since both standards are compatible. SVG is subset of the HTML5 language specification and therefore on the internet high level most advanced standard. PDF is only supported up to version 1.5 by Mathematica. There is already 1.7 published. The Adobe Systems version PDF 1.7 is the basis for this ISO 32000 edition as the newest valid standard since 2008, so very aged. SVG is too part of XML specification for example used by Word or OpenOffice.
Both pdf and svg can be viewed in the browser.
[](https://i.stack.imgur.com/IuzGE.png)
svg can be imported in many pdf editors as well. Compared to all Rasterizers this remain vector grafics and can be enlarged as the rest of an pdf without pixelation and other image distorsions. This is the official Adobe page for SVG: [enter link description here](https://www.adobe.com/devnet/svg.html). SCG is open source and complete part of Mathematica.
A tip is drag the output of the graphics input into the second field of the [`Export`](https://reference.wolfram.com/language/ref/Export.html) built-in for best results. |

Converting SVG to PDf is safe since both standards are compatible. SVG is subset of the HTML5 language specification and therefore on the internet high level most advanced standard. PDF is only supported up to version 1.5 by Mathematica. There is already 1.7 published. The Adobe Systems version PDF 1.7 is the basis for this ISO 32000 edition as the newest valid standard since 2008, so very aged. SVG is too part of XML specification for example used by Word or OpenOffice.
Both pdf and svg can be viewed in the browser.
[](https://i.stack.imgur.com/IuzGE.png)
svg can be imported in many pdf editors as well. Compared to all Rasterizers this remain vector grafics and can be enlarged as the rest of an pdf without pixelation and other image distorsions. This is the official Adobe page for SVG: [enter link description here](https://www.adobe.com/devnet/svg.html). SCG is open source and complete part of Mathematica.
A tip is drag the output of the graphics input into the second field of the [`Export`](https://reference.wolfram.com/language/ref/Export.html) built-in for best results. |
56,783,408 | How to have pass the value of a selected tableView to a public variable that can be accessed by multiple ViewControllers? Currently, in didSelectRowAt, I define the row selected as `portfolio` doing `let portfolio = structure[indexPath.row]` Now how can I save this value to perhaps some sort of variable that makes it avalible to multiple view controller?
I don't just mean pushing the value to whichever view controller is being presented when the cell is pressed, I need it be available to view controller past the .pushViewController.
In the past I tried using userdefaults, but this is not appropriate for values that are constantly changing and are not permanen.
```
import UIKit
class ScheduledCell: UITableViewCell {
@IBOutlet weak var ETALabel: UILabel!
@IBOutlet weak var cellStructure: UIView!
@IBOutlet weak var scheduledLabel: UILabel!
@IBOutlet weak var testingCell: UILabel!
@IBOutlet weak var pickupLabel: UILabel!
@IBOutlet weak var deliveryLabel: UILabel!
@IBOutlet weak var stopLabel: UILabel!
@IBOutlet weak var topBar: UIView!

var typeValue = String()
var driverName = UserDefaults.standard.string(forKey: "name")!
var structure = [AlreadyScheduledStructure]()

super.viewDidLoad()
fetchJSON()
//Disable delay in button tap
self.tableView.delaysContentTouches = false
tableView.tableFooterView = UIView()
}
private func fetchJSON() {

let value = driverName.addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed)
else { return }
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = "driverName=\(value)".data(using: .utf8)
URLSession.shared.dataTask(with: request) { data, _, error in
guard let data = data else { return }
do {
self.structure = try JSONDecoder().decode([AlreadyScheduledStructure].self,from:data)
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
catch {
print(error)
}
}.resume()

] | You can use a function to pass an optional Value inside an `extension`, try the following:
From what I understood you want to pass values from your `viewController` and be able to get it from any other `viewController`..
```
extension UIViewController {
func passData(row: Int?) -> Int? {
var myValue = Int()
if row != nil {
myValue = row!
}
return myValue
}
}
```
in this `function` you can Pass the value you want and also retrieve it.
to pass data into the `function` simply use this :
```
passData(row: indexPath.row)
```
and if you want to retrieve the value of it from another `viewController` use this:
```
let myValue = passData(row: nil)
```
this way you could get the Data you pass from another `viewController`..
if that didn't work for you I'd suggest you use `UserDefaults` ..
I hope this could solve your problem. | You can use NSNotificationCenter and post value after selection and every subscribed controller will received a new value.

292,332 | I was reading a question on Stack Overflow, and noticed that in the right side there was an empty ad, which consisted only of clouds over a blue sky:
It seemed curious to me that there were no info in the ad: no logo, no text, just a sky full of clouds. So I checked the source of the component, and noticed that it was not an image, but a group of DIVs, and the clouds where drawed using dots and CSS styles.
Just by mere curiosity, why is this ad empty, and instead of an image, it is an elaborated composite made of divs and text? | 2015/05/04 | [

The error is fixed, so you will no longer see any [happy clouds](https://www.youtube.com/watch?v=raXanYjTF18). | It's likely the result of someone who is very well versed in HTML and CSS, and also believes that SO deserves to run without ads. Instead of just straight donating to SO, they bought up an ad in order to contribute to SO's development and upkeep, while also preventing an amount of real (possibly invasive and annoying) ads from showing up on people's screens. |
62,071,886 | maybe one of you can help me. I've written a feature in javascript that adds underlining to all "a" selectors. The function is called with the "onclick" attribute. I would like to reverse the effect, i.e. remove the underscore at second click on the same button. The question is how to do it ?
HTML code:
```
<button type="button" class="underlineLinks" id="underlineLinks" onclick="underlineLinks()">Click</button>
```
JS code:
```
function underlineLinks() {
const links = document.querySelectorAll("a");
links.forEach(a => a.style.textDecoration = "underline");

] | You can create a CSS class with the decoration underline
```
.class
{
text-decoration: underline

and use toggle in the JS.
Toggle will add the class if it isn't applied to your link and remove the class if it is applied to your link
```
function underlineLinks() {
const links = document.querySelectorAll("a");
links.forEach(a => a.classList.toggle("class"));
}
```
<https://jsfiddle.net/u4sxfdy5/> | you could do this

function getUnderLineLinksSetter() {
let areLinksUnderlines = false;
return () => {
const links = document.querySelectorAll('a');
areLinksUnderlines = !areLinksUnderlines;
links.forEach(a => {
if (areLinksUnderlines) {
a.style.textDecoration = 'initial';
} else {
a.style.textDecoration = 'underline';
}
});
};
}
```
and then use the following html
```
<button type="button" class="underlineLinks" id="underlineLinks" onclick="getUnderLineLinksSetter()()">Click</button>
```
Its better to add event listeners from code and not using html inline functions by that i mean instead of setting the on click using html, you set it using javascript like this
```
// put this code inside a load event in the page so you make sure the button is in the dom
function getUnderLineLinksSetter() {
let areLinksUnderlines = false;
return () => {
const links = document.querySelectorAll('a');
areLinksUnderlines = !areLinksUnderlines;
links.forEach(a => {
if (areLinksUnderlines) {
a.style.textDecoration = 'initial';
} else {
a.style.textDecoration = 'underline';
}
});
};
}
document.getElementById('underlineLinks').addEventLisetner('click', getUnderLineLinksSetter())

A forma correta depende portanto do contexto. Se estou a resolver um problema de matemática, quando o terminar terei *acabado o problema*.
Se o problema é, por exemplo, um cano roto, ao resolver o problema terei *acabado **com** o problema*. | Imagine o seguinte! Há um encanamento quebrado que vaza água constantemente. Para "terminar o problema" você tenta tampar o buraco, com as mãos ou de alguma outra forma. Porém para "acabar com o problema" você apenas tranca o registro.

287,181 | I have a gigantic list of files on a text files. This list is passed to tar, like this:
cat list.txt | xargs tar rvf archive.tar --ignore-failed-read
The problem is that some files that are on the list don't exist anymore. So tar keeps saying "Cannot stat: No such file or directory...".
I have no problems with that, however when some of these messages appear, tar hungs, and wait some minutes to resume the actions, making the backup very slow.
Any ideas on how I can filter only the existing files to tar?
