A transportadora @TotalExpressbr é a pior transportadora atualmente! Você não consegue falar com eles... a empresa que contrata a entrega não consegue falar com eles... eles atrasam a entrega em vários dias e ao devolver, eles demoram um mês pra buscar e não te avisam qd buscar..

"Pode isso Arnaldo?" Você está na fila online de atendimento da #OLX @OLX_Brasil e do nada o número ao invés de diminuir aumenta!
Devem ter colocado a mãe de algum diretor na frente né? Hehehehe

I'm facing a bad situation after buying KeebDeck Basic from @lectronz (dev by @solderparty).
The problem happened by Lectronz said they will send an email when the item was shipped.
That email never came, then I didn't track the object and Brazilian Customs returned it.

A taxa das blusinhas do "economista" @Haddad_Fernando colocou os últimos pregos no caixão dos #Correios. Deveriam ter privatizado esta jaca enquanto era tempo! Agora as empresas fizeram lobby pra taxação também estão começando a perder, pois o Aliexpress criou armazéns no Brasil!

I'm having a hard time with @AliExpress_EN they combined 6 purchases in a single package and then Brazilian Customs returned it because they said there is not good description of the item (NM931299947BR). They gave me refund of an item (8204978967149167) but not for the other 5!

Estou tentando há mais de uma semana ativar a Garantia @OLX_Brasil e não consigo. O suporte deles não consegue resolver, apenas dizem que deve ter algo errado nos meus dados, mas já conferi mil vezes! Nunca tive problemas no @MercadoLivre. Por favor respondam ao ticket aberto!

I was invited to talk at Xiaomi Vela (powered by NuttX) IoT Dev Conference. I was surprised how big NuttX is in China, too many silicon semiconductor companies have support for it (Espressif, GigaDevice, Allwinner, Bouffalo Lab, BES, Sifli, Barrot, etc). Start spreading the NuttX

O Brasil é mesmo o país da piada pronta: o novo "imposto do pescado", que será um tributo adicional que incidirá sobre produtos e serviços considerados prejudiciais à saúde humana e ao meio ambiente, vai taxar veículo elétricos e isentar caminhões pela importância logística! WTF?
