Saw the Wendy show from last year when she talked about him and Amber and their "equal opportunity USEastion" then saw yesturday where she was making it very clear that she always agree we should all "date a lot and often so you can find who you want to settle down with." Lol the look on Val face still showed he still doing this. He need to get his stalker to do the same. She has no clue what geunion love is. Being made a side chick for 4 years is not it. Cause they not it at all even in public.

Since this post is back around again I'll talk some about a dude I used to play Diablo with before WoW came out. His online alias was Carver and his name was Ryan, although I didn't find that last one out for quite a while. He lived in Hawaii with his brother, we led a clan on the USEast battle.net server called Blood Legion. Last I heard from him - around 2002 - he had joined the Marine Corps and was stationed in Turkey. He was a really great guy, I hope he's still in one piece somewhere and making a good life for himself.

Shout out to all your internet friends who are gone.

Those messenger screen names that haven’t logged on in ages, some before detailed profiles were a thing on those services.

Those emails that are long since abandoned, some with domains that no longer exist.

Those online friends you knew years ago and who then helped shaped you in some way, who you just can’t FIND anymore.

Those people who once were, and hopefully still exist IRL, that seem to have no known internet life anymore.

And those who have actually passed on, and their online lives are now a memorial to them.

I miss you all. I hope life is/was kind to you, and maybe one day, we’ll somehow connect again.

Shortwave Radiogram, 30 September-3 October 2021: Digital modes that enrich the lunar soil

The Vienna Wireless Society, the amateur radio club in Vienna, Virginia, near Washington DC, kindly invited me to speak to their meeting on September 24 about Shortwave Radiogram, including its history, goals and great audience. A video of that presentation is available at youtu.be/wlThN6kS4k0. It's hard to believe that it is (almost) October already. The images of the week will be featuring more of the oranges, yellows and reds of autumn. One of the images that I had to cut for lack of time is a pumpkin patch in Potomac, Maryland. There will, however, be plenty of pumpkin photos available for the shows later in October. These pumpkins were left on the cutting room floor ...

Migrate to an Amazon Aurora PostgreSQL instance from another PostgreSQL source

Amazon Aurora with PostgreSQL compatibility combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open-source databases. Aurora provides this by scaling storage across three Availability Zones in the same Region, and supports up to 15 read replica instances for scaling out read workloads and high availability within a single Region. With Amazon Aurora Global Database, you can now replicate PostgreSQL databases in up to five Regions for remote read access and disaster recovery in the event of the failure of an entire Region. Due to these features, many customers are migrating their databases to Aurora PostgreSQL. This post talks about migrating an Aurora PostgreSQL instance from another PostgreSQL source, which can be an existing Amazon RDS for PostgreSQL instance or self-managed PostgreSQL instance (installed on an Amazon Elastic Compute Cloud (Amazon EC2) instance or on-premises). Prerequisites To reduce the time of the migration process, you can reduce the size of the database before you start the migration. You have the following options: Run VACUUM FULL/REINDEX or pg_repack on the database Archive or remove any old or temporary data Running VACUUM FULL or pg_repack on the database You can check the bloat on the database using a bloat query, which shows the sizes of tables and indexes with actual size and the size that can be reduced by running VACUUM FULL or REINDEX on a particular table or index. These maintenance activities need the ACCESS EXCLUSIVE lock in the objects, which doesn’t allow any SQL on the object. You can use the pg_repack extension to remove bloat from tables and indexes. This extension is supported on Amazon RDS for PostgreSQL versions 9.6.3 and later. For more information, see Working with the pg_repack Extension. Also, you can remove duplicate or unused indexes in your database using the following two queries. Use the following query for unused indexes: WITH table_scans as ( SELECT relid, tables.idx_scan + tables.seq_scan as all_scans, ( tables.n_tup_ins + tables.n_tup_upd + tables.n_tup_del ) as writes, pg_relation_size(relid) as table_size FROM pg_stat_user_tables as tables ), all_writes as ( SELECT sum(writes) as total_writes FROM table_scans ), indexes as ( SELECT idx_stat.relid, idx_stat.indexrelid, idx_stat.schemaname, idx_stat.relname as tablename, idx_stat.indexrelname as indexname, idx_stat.idx_scan, pg_relation_size(idx_stat.indexrelid) as index_bytes, indexdef ~* 'USING btree' AS idx_is_btree FROM pg_stat_user_indexes as idx_stat JOIN pg_index USING (indexrelid) JOIN pg_indexes as indexes ON idx_stat.schemaname = indexes.schemaname AND idx_stat.relname = indexes.tablename AND idx_stat.indexrelname = indexes.indexname WHERE pg_index.indisunique = FALSE ), index_ratios AS ( SELECT schemaname, tablename, indexname, idx_scan, all_scans, round(( CASE WHEN all_scans = 0 THEN 0.0::NUMERIC ELSE idx_scan::NUMERIC/all_scans * 100 END),2) as index_scan_pct, writes, round((CASE WHEN writes = 0 THEN idx_scan::NUMERIC ELSE idx_scan::NUMERIC/writes END),2) as scans_per_write, pg_size_pretty(index_bytes) as index_size, pg_size_pretty(table_size) as table_size, idx_is_btree, index_bytes FROM indexes JOIN table_scans USING (relid) ), index_groups AS ( SELECT 'Never Used Indexes' as reason, *, 1 as grp FROM index_ratios WHERE idx_scan = 0 and idx_is_btree UNION ALL SELECT 'Low Scans, High Writes' as reason, *, 2 as grp FROM index_ratios WHERE scans_per_write <= 1 and index_scan_pct < 10 and idx_scan > 0 and writes > 100 and idx_is_btree UNION ALL SELECT 'Seldom Used Large Indexes' as reason, *, 3 as grp FROM index_ratios WHERE index_scan_pct < 5 and scans_per_write > 1 and idx_scan > 0 and idx_is_btree and index_bytes > 100000000 UNION ALL SELECT 'High-Write Large Non-Btree' as reason, index_ratios.*, 4 as grp FROM index_ratios, all_writes WHERE ( writes::NUMERIC / ( total_writes + 1 ) ) > 0.02 AND NOT idx_is_btree AND index_bytes > 100000000 ORDER BY grp, index_bytes DESC ) SELECT reason, schemaname, tablename, indexname, index_scan_pct, scans_per_write, index_size, table_size FROM index_groups; For duplicate indexes, use the following query: SELECT indrelid::regclass AS TableName ,array_agg(indexrelid::regclass) AS Indexes FROM pg_index GROUP BY indrelid ,indkey HAVING COUNT(*) > 1; Archiving or removing old or temporary data If you notice that some data has been created temporarily for testing purposes during some development process and not cleaned up yet, you can remove that old or temporary data, reducing the size of the database and therefore snapshot time. You can use the DROP or TRUNCATE table options to get rid of unused or temporary tables. Migrating from RDS PostgreSQL to Aurora PostgreSQL You have two options when migrating data from RDS PostgreSQL to Aurora PostgreSQL: Use an RDS PostgreSQL snapshot Use an Aurora Read Replica for RDS PostgreSQL Your migration option depends on your use case. In this section, we discuss the purposes of these options and how to complete the migration. Using an RDS PostgreSQL snapshot In this option, you use the snapshot created for your existing RDS PostgreSQL instance to create an Aurora PostgreSQL instance. You may want to use this option with the following use cases: You want your Aurora PostgreSQL instance in a different Region than your existing RDS PostgreSQL instance You want your Aurora PostgreSQL instance in a different AWS account than your existing account Your existing RDS PostgreSQL is version 9.5 or older For our use case, you have the RDS PostgreSQL instance in a us-east Region and want to create an Aurora PostgreSQL instance in a us-west Region. For this, you need to complete the following high-level steps: Create a snapshot of RDS PostgreSQL. Copy the snapshot. Share the snapshot to the required AWS Region or account. Create Aurora PostgreSQL using the snapshot. Creating a snapshot of RDS PostgreSQL To create your snapshot, complete the following steps: On the Amazon RDS console, choose Databases. Select the RDS PostgreSQL instance that you want to migrate. From the Actions drop-down menu, choose Take snapshot. For Snapshot name, enter a name for your snapshot (for example, to-create-aurorapg). Choose Take Snapshot. To see your snapshot, choose Snapshots from the navigation pane. The snapshot is listed on the Manual tab. For full instructions, see Creating a DB Snapshot. Copying the snapshot In this step, you copy an encrypted or unencrypted DB snapshot, in the same Region or across Regions. On the Amazon RDS console, choose Snapshots. On the Manual tab, select the snapshot you want to copy. From the Actions drop-down menu, choose Copy Snapshot. For this post, we copy the snapshot from us-east to us-west. The destination Region must have the same database engine version available as the source Region. For Destination Region, choose US West (N. California). For New DB Snapshot Identifier, enter to-create-aurorapg-from-useast. For Encryption, select Disable encryption. If you want to encrypt the snapshot irrespective of if your source snapshot is encrypted or not, choose Enable encryption. Then for Master Key, specify the AWS Key Management Service (AWS KMS) key identifier to use to encrypt the DB snapshot copy. Choose Copy snapshot. You can view the progress of the snapshot on the Snapshots page. In the following screenshot, the snapshot is in the process of being copied in us-west. Sharing a DB snapshot You can share a DB snapshot (which is taken manually) to 20 AWS accounts, and can also stop sharing the snapshot for one or more accounts. On the Amazon RDS console, choose Snapshots. Select the snapshot you want to share. From the Actions drop-down menu, choose Share Snapshot. For DB snapshot visibility, select Public or Private. If the source is unencrypted, choose Public to permit all AWS accounts to restore a DB instance from your snapshot, or choose Private to permit only AWS accounts that you specify. For AWS account ID, enter the account you want to share the snapshot with and choose Add. Repeat to include additional AWS accounts, up to 20. Choose Save. To stop sharing a manual DB snapshot with an AWS account, repeat steps 1-3. On the Snapshot permissions page, enter the ID of the account you want to delete and choose Delete. Creating an Aurora PostgreSQL instance using the snapshot After you create the snapshot of your RDS PostgreSQL instance and share with the Region or account that you want, you can create an Aurora PostgreSQL instance using that snapshot. On the Amazon RDS console, choose Snapshots. Select the snapshot you want to migrate to an Aurora PostgreSQL DB cluster. From the Actions drop-down menu, choose Migrate snapshot. For Migrate to DB Engine, choose your database engine (for this post, aurora-postgresql). For DB Engine Version, enter the version number of your database engine (for this post, 4). For more information about setting those values, see Migrating an RDS PostgreSQL DB Snapshot to an Aurora PostgreSQL DB Cluster. Using an Aurora Read Replica for RDS PostgreSQL As a second option, you can migrate from an RDS PostgreSQL DB instance to an Aurora PostgreSQL DB cluster by using an Aurora Read Replica. This is the best approach if you want to migrate your RDS PostgreSQL to Aurora PostgreSQL within the same Region and account. However, this migration may take some time depending on the data size, roughly several hours per tebibyte (TiB) of data. Large databases under heavy load take a long time to sync. While the migration is in progress, your Amazon RDS for PostgreSQL instance accumulates write ahead log (WAL) segments for the initial sync and catch-up to happen. Make sure that your Amazon RDS instance has enough free storage available to hold these WAL files. In this case, Amazon RDS uses the PostgreSQL DB engine’s streaming replication functionality to create a special type of DB cluster for the source PostgreSQL DB instance. This type of DB cluster is called an Aurora Read Replica. Updates made to the source PostgreSQL DB instance are asynchronously replicated to the Aurora Read Replica. This migration option has two steps: Create an Aurora PostgreSQL Read Replica for RDS PostgreSQL. Promote the Aurora PostgreSQL Read Replica to an Aurora PostgreSQL cluster. Creating an Aurora Read Replica To create an Aurora Read Replica for a PostgreSQL DB instance, complete the following steps: On the Amazon RDS console, choose Databases. Select the PostgreSQL DB instance you want to use as the source for your read replica. From the Actions drop-down menu, choose create Aurora read replica. On the Create Aurora Read Replica page, choose your options accordingly. Choose Create read replica. For full instructions, see Creating an Aurora Read Replica. Promoting the Aurora PostgreSQL Read Replica to an Aurora PostgreSQL Cluster You’re now ready to promote your read replica to an Aurora PostgreSQL cluster. On the Amazon RDS console, choose Instances. Select the DB instance for the read replica. From the Actions drop-down menu, choose Promote. Choose Promote Read Replica. Migrating from a self-managed PostgreSQL instance to an Aurora PostgreSQL instance If you have an existing PostgreSQL deployment on an EC2 instance or on-premises that you want to move to an Aurora PostgreSQL instance, then the complexity of your task depends on the size of your database and the types of database objects that you’re transferring. For example, consider a database that contains datasets on the order of gigabytes, along with stored procedures and triggers. Such a database is more complicated than a simple database with only a few megabytes of test data and no triggers or stored procedures. For this use case, you can consider using the following options: pg_dump and pg_restore Logical replication AWS Database Migration Service (AWS DMS) replication Using pg_dump and pg_restore pg_dump and pg_restore are PostgreSQL native tools to  create and restore a backup, respectively. You can create this backup on a production environment because it doesn’t block readers and writers. However, because this isn’t a continuous backup, you have to stop the application or stop writing to the database from the application before you initiate the backup. For instructions, see Importing a PostgreSQL Database from an Amazon EC2 Instance. Using Logical Replication Logical Replication is another way to migrate data from one PostgreSQL instance to another. Logical Replication is a method of replicating data objects and their changes, based upon their replication identity (usually a primary key). It is introduced in PostgreSQL 10, but you can use the pglogical extension if you have an older version than PostgreSQL 10. For more information about enabling and using logical replication, see Using PostgreSQL Logical Replication with Aurora. For instructions on setting up logical replication, see Migrating PostgreSQL from on-premises or Amazon EC2 to Amazon RDS using logical replication. Using AWS DMS replication You can use AWS DMS to migrate data from your database that is on-premises, on an RDS DB instance, or in a database on an EC2 instance to a database on an AWS service like Aurora PostgreSQL. Because you can replicate the changes continuously using AWS DMS, you don’t need to stop your application. For instructions, see Using DMS to migrate data from PostgreSQL to PostgreSQL. For more information about AWS DMS, see the AWS DMS User Guide. Summary This post talked about the different available options to import data to an Aurora PostgreSQL instance. Although you can choose from multiple options, each one has a specific purpose or use case: If you want to migrate from RDS PostgreSQL to an Aurora PostgreSQL instance in a different AWS Region or AWS account, you can consider using a snapshot. If you want to migrate from RDS PostgreSQL to Aurora PostgreSQL within the same Region, the best option is to create an Aurora Read Replica for your RDS PostgreSQL instance. If you want to migrate your RDS PostgreSQL with a different Region or account or PostgreSQL on Amazon EC2 or on-premises instances with minimal downtime, consider using AWS DMS.

CDN is short for Content Delivery Network. It's a geographically distributed group of servers that work together to provide fast delivery of internet content.

Content: The content or assets can be anything, HTML pages, CSS files, Javascript files, images, videos, songs etc. So when we type this line :

<link href="https://fonts.googleapis.com/css?family=Roboto&display=swap" rel="stylesheet">

we're basically asking google fonts to provide us with the particular font design.

Delivery: Self-explanatory.

Network: Why is it called network? It's called a network since bunch for servers work together to send "content" back to the client.

If you've played any of multiplayer online games like Dota or CS:GO, there's a command which we type: "ping" and it returns something like "100ms" or "40ms".

dota 2 ping for different regions

Ping is how much time it takes for the server to return the content asked by the client. So 100ms means that it takes 100ms for client -> server -> client data transfer. So in this case, if I am connected to a USEast server, then the data exchange between me and the server on which the actual game is running takes 26ms.

But why a cluster of servers?

Now imagine you're in US, and you want to play with your friend in India so you decide to join a server in India. So for data transfer between you and the server now takes 300ms on average, which doesn't seem much but for a high paced game like Dota, it's too much or as gamers call it "LAG".

Here's an example of the same in Fortnite:

In this case if player 1 ping = 300ms and player 2 ping = 26ms, the actions performed by player 2 are received, processed, and distributed much faster compared to player 1.

The same applies to all other services like Netflix, Spotify etc. It would be unfeasible to store all movies and TV shows, at one location. To tackle this, they install a bunch/cluster of servers in many different locations that contain data, and these in turn are connected to the main server which provides all the data.

Implementing this kind of network has many advantages:

1> Decreased load : Each server will serve customers in that region which brings down server load of whole system.

2> Faster Content Delivery : Since load is decreased, it's easier on server transfer files.

3> Protection against potential DDOS attacks : Since there are many servers located, if one server is affected by DDOS attack, other backup servers will kick into action and serve customers in that region, and overloading the main server becomes difficult.

4> Analytics : Companies like Netflix use the data about things like, most-watched movies / TV shows in that region and use that data to update their regional servers so that relevant content is available to customers.

Eg: if customers in US are watching "Stranger Things" at high demand and customers in South Korea are watching "Kingdom", Netflix will update their local US and Korean servers accordingly.

Netflix, in particular, goes beyond. Netflix ties up with local ISP to install boxes similar to these :

Since the population density of Mumbai is higher compared to that of New York, Netflix might end up installing more of these boxes in Mumbai to serve their customers.

Com o fim do isolamento haverá leito de UTI para todos?

Se o país sofrer uma escalada de casos graves de Covid-19, sobretudo a medida que se aproxima o fim da quarentena – inicialmente prevista para até o próximo dia 10 de abril – pacientes podem enfrentar falta de leitos de terapia intensiva, alerta a Associação de Medicina Intensiva Brasileira (Amib).

Nos epicentros da pandemia, de acordo com a Amib, a demanda exige dos países 2,4 leitos de UTI para cada 10 mil habitantes. No entanto, o Brasil não alcança essa demanda, ainda que sejam somados os leitos da rede pública e privada.

Ao todo, o Brasil conta com 47 mil leitos, sendo que apenas 32 mil são equipados para atender adultos. Metade deles estão no Sistema Único de Saúde (SUS) e a outra nos hospitais particulares.

O Sistema Único de Saúde (SUS) dispõe, em média, de 1 leito para cada 10 mil habitantes. Na rede privada, a razão é de 4 leitos para cada 10 mil beneficiários de plano de saúde.

A questão crítica, alerta a Amib, é que para 75% da população a única opção é o SUS. É preciso considerar, ainda, que a rede pública tem em média 95% destes leitos já ocupados por pacientes com outras doenças.

Apenas 10% dos municípios brasileiros tem leitos de UTI, levando à transferência contínua de pacientes para hospitais de referência nas capitais.

Outra preocupação das entidades médicas é que pacientes com o novo coronavírus permaneces na UTI cerca de 14 dias, por conta do isolamento.

Pela ameaça de sobrecarga ou disparada de contágio, o ministro da Saúde, Luiz Henrique Mandetta, prevê que o sistema de saúde entre em colapso em abril.

O que é um colapso? Você pode ter o dinheiro, o plano de saúde, mas simplesmente não há sistema para você entrar.

Luiz Henrique Mandetta

Para que os estados e municípios equipem seus hospitais com mais leitos de UTI, o Governo Federal liberou R$ 600 milhões. Apesar de tudo, fora pandemia, a rede pública do Brasil alcança a recomendação da Organização Mundial de Saúde (OMS), ou seja: 1 a 3 leitos a cada 10 mil habitantes.

Estado crítico

O Conselho Federal de Medicina (CFM) chegou a calcular a proporção por região, em estudo de 2018. O estudo aponta que no Sudeste apenas o Rio de Janeiro não tem leitos suficientes. No estado do Rio, a razão é de 0,97 leitos por 10 mil habitantes.

A situação mais crítica é no Norte do país, onde apenas o estado de Rondônia alcança a recomendação da OMS. O panorama é similar no Nordeste, região na qual apenas Pernambuco e Sergipe alcançam a razão de 1 leito de UTI a cada dez mil habitantes.

No Centro-Oeste, apenas Goiás alcança. O Sul tem a maior proporção de leitos por habitante. No entanto, ainda insuficiente para a demanda de 2,4 leitos registrada nos epicentros da doença.

O mapa a seguir mostra o total de leitos no SUS e na rede particular, e a razão por estado, com base no estudo do Conselho Federal de Medicina.

Ampliação de leitos

Com o avanço da pandemia — o Rio de Janeiro alcançou nove mortes e 421 casos confirmados nesta quinta-feira (26), quando o estado completou três semanas desde o primeiro caso — , municípios e estados incluíram no plano de contingência a instalação de novos leitos de UTI.

No início da pandemia, o governo estadual acelerou a abertura de 299 leitos, na Capital e em Volta Redonda. A Secretaria de Estado de Saúde pressiona, ainda, pela reabertura de 950 leitos desativados em hospitais federais.

Outra iniciativa para suprir a demanda parte dos municípios. Na Região Metropolitana, São Gonçalo está equipando leitos no Hospital Municipal Luiz Palmier para torná-lo unidade de referência no tratamento da Covid-19.

São Gonçalo também receberá um dos três hospitais de campanha previstos pelo governo estadual. A Prefeitura de Maricá, está acelerando a entrega do Hospital Municipal Che Guevara, com 19 leitos de UTI.

Niterói tomou um rumo diferente: na segunda semana de contágio, a cidade fechou parceria com hospitais privados para disponibilizar leitos de urgência. Em seguida, a cidade arrendou um hospital, que servirá como unidade hospitalar de campanha municipal com 140 leitos.

Se executados, os investimentos previstos devem representar aumento de 28% na capacidade de terapia intensiva no estado.
