Inked ladies: Vintage photos of women with full body tattoos | Dangerous Minds

http://dangerousminds.net/comments/inked_ladies_vintage_photos_tattoos

The 1991 discovery of the well-preserved body of a 3,000-year-old corpse revealed (amongst many other things) that ancient humans tattooed their bodies. The mummified body was called “Ötzi the Iceman” after the Ötztal Alps where his remains were found. Ötzi had 50-odd tattoos across his body, which some scientists have suggested may be evidence of an early form of acupuncture—which if true, would put this form of treatment 2,000 years before its first documented appearance in China. Tattoos have a long and culturally significant history—being used as a sign of initiation, association, clan, tribe, ownership, or sexual and personal...

Microsoft has a Surface Laptop ‘Smurface Edition’ for Smurfs fans. | The Verge

https://www.theverge.com/news/715741/microsoft-surface-laptop-smurface-edition

Microsoft rarely does limited editions of its Surface products, but it has quietly launched a “Smurface Edition” in time for the Smurfs movie. I was expecting it to be a totally blue design, but instead Microsoft has laser-etched the Smurfs to the front, alongside a blue Surface logo. Other than that, it’s a 13-inch Surface Laptop 7 with Qualcomm’s Snapdragon X Plus, 16GB of RAM, and 512GB of storage for $999.99. Only 100 units are available, exclusively at Amazon.

modernc.org/sqlite with Go - The IT Solutions

https://theitsolutions.io/blog/modernc.org-sqlite-with-go

I had long been aware of the [effort of cznic](https://gitlab.com/cznic/sqlite) to automatically translate the C source of SQLite to Go while avoiding the complexity CGo would introduce. SQLite was always meant to be a database you embed into your application, and I was curious what tradeoffs that meant, if any, and just generally how it differed from the usual suspects (PostgreSQL, etc.). To explore these trade-offs and differences, I decided to dive deeper into the usage of this library. SQLite is a single-writer multiple-reader database. Using just a single instance of database/sql.DB will not work well with this, because it will make it hard to avoid receiving SQLITE_BUSY errors when multiple writers try to run at the same time (because sql.DB is a connection pool). So we will need to separate readers from writers by making two instances of database/sql.DB and limiting the writer to a single [MaxOpenConn](https://pkg.go.dev/database/sql#DB.SetMaxOpenConns) and the reader to as many as you require. So far, SQLite is behaving remarkably like other databases apart from the single-writer gotcha; we still have connections and per-connection settings. The usual way to pass these settings is usually in the DSN you pass to [sql.Open](https://pkg.go.dev/database/sql#Open) and this is [definitely possible](https://pkg.go.dev/modernc.org/sqlite#Driver.Open), but I find that it would be more straightforward if I could just run my custom SQL when a new connection is made[1]. We can do that with [sqlite.RegisterConnectionHook](https://pkg.go.dev/modernc.org/sqlite#RegisterConnectionHook). Now the question is what settings to use, because [there are quite a few of them](https://www.sqlite.org/pragma.html). These are the ones I am using personally: - `PRAGMA journal_mode = WAL;` Use write-ahead-logging. Better concurrency, but with an edge-case: with heavy writers, the wal can grow idefinitely ([see for more](https://www.sqlite.org/cgi/src/doc/wal2/doc/wal2.md)). I don't expect this will happen in my use-case. For a good description on the various jornal modes, [see this blogpost](https://www.mycelial.com/learn/sqlite-journal-mode-options). - `PRAGMA synchronous = NORMAL;` Since with the WAL journal mode, this is safe, there is no reason to use FULL. - `PRAGMA temp_store = MEMORY;` Let's store temporary indices, tables, etc. in memory, my use-case is not very resource-constrained to require using the filesystem (also, [this is a fun read](https://www.sqlite.org/fasterthanfs.html) if we are talking about additional syscalls to the kernel) - `PRAGMA mmap_size = 30000000000; -- 30GB` Just making sure, access to my database is always done with memory-mapped I/O. - `PRAGMA busy_timeout = 5000;` How much time to wait in milliseconds after which SQLITE_BUSY is returned when waiting for the db to unlock. - `PRAGMA automatic_index = true;` Make sure [automatic indexing](https://www.sqlite.org/optoverview.html#autoindex) is enabled, it can only help, and is a great way to get warnings about indexes that should be created. - `PRAGMA foreign_keys = ON;` Make sure foreign key enforcement is enabled. - `PRAGMA analysis_limit = 1000;` Make sure [ANALYZE](https://www.sqlite.org/lang_analyze.html#approx) returns quickly in case the DB gets large. - `PRAGMA trusted_schema = OFF;` No idea what security audited functions are, but this setting makes sure only those can be run. The manual page tells me to turn it off anyway, so let's do that. Not all of these settings are per-connection settings, but it doesn't hurt to always run all of these on every connection, and having a single "Init SQL" makes things simpler. Let's deal with explicit transactions next. The default transaction mode is DEFERRED, meaning that it depends on the next statement what type of transaction is started (if a SELECT statement comes first, a read transaction is started, with the possibility of upgrading it to a write transaction depending on the statements that follow). With our setup, there should never be multiple writers concurrently, so making all transactions write transactions from the get-go (with BEGIN IMMEDIATE) can only help us show if this invariant is violated. Putting this all together, this is the code we arrive at: ```go package main import ( "bytes" "context" "crypto/sha1" "database/sql" "database/sql/driver" "encoding/hex" "fmt" "time" "modernc.org/sqlite" ) type DB struct { dbPath string Read *sql.DB Write *sql.DB } const initSQL = ` PRAGMA journal_mode = WAL; PRAGMA synchronous = NORMAL; PRAGMA temp_store = MEMORY; PRAGMA mmap_size = 30000000000; -- 30GB PRAGMA busy_timeout = 5000; PRAGMA automatic_index = true; PRAGMA foreign_keys = ON; PRAGMA analysis_limit = 1000; PRAGMA trusted_schema = OFF; ` func New(ctx context.Context, dbPath string) (db *DB, err error) { db = &DB{ dbPath: dbPath, } // make sure every opened connection has the settings we expect sqlite.RegisterConnectionHook(func(conn sqlite.ExecQuerierContext, _ string) error { _, err = conn.ExecContext(ctx, initSQL, nil) return err }) write, err := sql.Open("sqlite", "file:"+db.dbPath) if err != nil { return } // only a single writer ever, no concurrency write.SetMaxOpenConns(1) write.SetConnMaxIdleTime(time.Minute) if err != nil { return } read, err := sql.Open("sqlite", "file:"+db.dbPath) if err != nil { return } // readers can be concurrent read.SetMaxOpenConns(100) read.SetConnMaxIdleTime(time.Minute) db.Read = read db.Write = write return } func (db *DB) InTransaction(ctx context.Context, tx func(context.Context, *sql.Conn) error) (err error) { // cancel anything that takes longer than 5 seconds var cancel func() ctx, cancel = context.WithTimeout(ctx, time.Duration(5*time.Second)) defer cancel() // separate conn thats just for us // so that the transactions queries are executed together conn, err := db.Write.Conn(ctx) if err != nil { return } defer conn.Close() _, err = conn.ExecContext(ctx, "BEGIN IMMEDIATE TRANSACTION") if err != nil { return } defer func() { if r := recover(); r != nil || err != nil { if _, err = conn.ExecContext(ctx, "ROLLBACK"); err != nil { return } } }() err = tx(ctx, conn) if err != nil { return } _, err = conn.ExecContext(ctx, "COMMIT") return } ``` Just as a small added bonus, it's also very easy to register our own go functions that we can then call from SQL. In this example, we define the sha1 function, receiving and returning a single argument, and always returning the same output for the same input (thus the deterministic). For more information, [see the docs](https://www.sqlite.org/appfunc.html) ```go func registerFuncs() { // lets add our own sha1 hash function usable from SQL sqlite.MustRegisterDeterministicScalarFunction( "sha1", 1, func(ctx *sqlite.FunctionContext, args []driver.Value) (driver.Value, error) { var arg *bytes.Buffer switch argTyped := args[0].(type) { case string: arg = bytes.NewBuffer([]byte(argTyped)) case []byte: arg = bytes.NewBuffer(argTyped) default: return nil, fmt.Errorf("expected argument to be a string, got: %T", argTyped) } h := sha1.Sum(arg.Bytes()) return hex.EncodeToString(h), nil }, ) } ``` In conclusion, this solution works perfectly well for most of the usage scenarios out there where immense scaling is neither expected nor needed. There are faster ways to use SQLite with Go (see the [excellent cvilsmeier benchmarks](https://github.com/cvilsmeier/go-sqlite-bench)), but its still plenty-fast enough, and avoiding CGo makes it very convenient also. [1]: This is another thing that database/sql.DB being a connection pool makes harder.

When you start with a cloud, you rarely get everything just right on the first try. Most projects begin with IaCafter they’ve already been using AWS for some time - which means you’ll have a bunch of resources that have been created using the AWS Console,and they have to be imported into Terrafor...

Whitelisting IPs in OSSEC | Geek Cabinet

https://geekcabi.net/posts/ossec-whitelisting/

All of this was prior to the latest versions of Security Onion which now run inside docker instances. I’ve not yet looked to see how this would be replicated there. But I’m leaving this up for historical purposes. Another tool in the arsenal of Security Onion is OSSEC, a “scalable, multi-platform, open source Host-based Intrusion Detection System (HIDS).” OSSEC examines log and alert events and correlates them against pre-built (or custom) rules and sends alerts as configured. When installed on the Security Onion server, OSSEC alerts are logged in the sguil database and managed alongside alerts from the network IDS.
