SLAMMER is back for another go-round: http://blog.checkpoint.com/2017/02/02/sql-slammer-comeback/Taking bets that someone plugged an infected, unpatched machine back into the network for some reason, thus bringing SLAMMER back from the ash heap of history?
How do we know this is hitting just SQL 2000? Couldn't one of the current versions of SQL have accidentally re-introduced the bug that made SLAMMER so effective in the first place?
Doubt that's the case, the UDP buffer overflow flaw was a spectacular cock up, it would take a truly supreme idiot to repeat that one.
😎No worries, Eirikur, the world has an uncanny ability to always produce a better idiot. :hehe:
Spot on or should I say off, the idiots just keep coming better and better Ed

Not to worry anyone but the first day of the DBA training this week has been very informative. I've learned more that I can use in eight hours than I did in the last two BI courses. There'll be a box-fresh idiot throwing away his BI plates and hitting the servers soon.

Not just aninfected unpatched machine - for that thing to propagate there have to be misconfigured firewalls too.

For the presenters out there do you use the USB presentation clicker with the laser light when talking to a group?

BLOB EATER - Tuesday, February 7, 2017 4:28 AMFor the presenters out there do you use the USB presentation clicker with the laser light when talking to a group?
Always.
Got it as a gift (I believe from SQL Sat Portland) a few years back and never want to present without it anymore.
(I don't use the laser light often, many screens have too much light that the audience cannot see it and in recorded sessions it is totally useless for the recording), But the ability to move around and still be able to advance my slides without having to walk back to the desk every time is a huge benefit

ok nice, I think I will too. I like the thought of moving around and not rushing back to the laptop to advance the slides.

Yes.
For small groups I use the laser pointer less because I can usually walk right up to the screen. However, I almost always control the slides remotely. I don't present behind a table or a lectern. I walk around.

I was thinking of submitting a script that could hopefully be published in about 2 months. But I wanted to get your expertise on things that might be slipping my mind.
It's a function for ROT26 encryption which will include an example on applying it twice for extra security. Let me know if you have any ideas on how to make it more "robust".
IF OBJECT_ID('dbo.iROT26') IS NOT NULL
DROP FUNCTION iROT26;
GO
CREATE FUNCTION dbo.iROT26(
@String nvarchar(100)
)
RETURNS TABLE WITH SCHEMABINDING
AS RETURN
WITH
E(n) AS(
SELECT n FROM (VALUES(0),(0),(0),(0),(0),(0),(0),(0),(0),(0))E(n)
),
E2(n) AS(
SELECT a.n FROM E a, E b
),
E4(n) AS(
SELECT a.n FROM E2 a, E2 b
),
cteTally(n) AS(
SELECT TOP(LEN(@String))ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) n
FROM E4
)
SELECT ( SELECT NCHAR(UNICODE(SUBSTRING(@String, n, 1)) * POWER(26,0))
FROM cteTally
WHERE n <= DATALENGTH(@String) / 2
FOR XML PATH(''), TYPE).value('./text()[1]', 'varchar(max)') rot26String;
GO
SELECT p.rowguid,
p.LastName,
r2.rot26String
FROM AdventureWorks2014.Person.Person p
CROSS APPLY dbo.iROT26( p.LastName) r
CROSS APPLY dbo.iROT26( r.rot26String) r2;

I think you should convert this to a scalar function....you know, for performance. :laugh:

Yes. Absolutely, without question. The only time I'm at the keyboard of my laptop is for demos.
My old one failed a couple months before PASS, and that was a crisis!

Hey, looking up syntax on the interwebs is really hard.

Nope, not Silver Spoon but falls in the same category.

I read that post. Yes, definitely in the same SS category. I'm waiting for a followup question asking the same thing again.
