Hi there.

I'm looking to pivot to SWE from Data Science (I'm early in my career), and I have an interest in decentralised networks and P2P systems in particular.

I'm working through "Distributed Services With Go" to build up some knowledge of distributed systems (I know it's far from a complete resource) more generally.

I'm aware that this is a tough enough sub-field that getting real knowledge in it is a massive undertaking, especially for someone who lacks work experience. I'm not expecting that learning this stuff will increase my chances of getting hired. However, I've decided to work through the book anyway out of interest.

If anyone shares my interests and would like to work through it with me, or potentially work on related projects afterwards, please DM me.

Hey , I've been building gpdf, a PDF generation library written in pure Go with zero external dependencies.

The problem

gofpdf is archived, maroto's layout is limited, and most serious solutions end up wrapping Chromium (hello 300MB binary and slow cold starts) or require commercial licensing. I wanted something fast, dependency-free, and with a real layout engine that treats CJK text as a first-class citizen.

What it does

• Full layout engine — Bootstrap-style 12-column grid system

• Declarative Builder API — chainable, no XML/JSON templates needed

• TrueType font embedding with full Unicode / CJK support

• Images, tables, headers/footers, page numbering

• Flexible units (pt / mm / cm / in / em / %)

What makes it different

• Zero dependencies — stdlib only, no CGo, no wrappers. go get and you're done

• Fast — 10–30x faster than comparable libraries in benchmarks. A typical invoice generates in under 1ms

• CJK-first — Japanese, Chinese, Korean text just works. Most Go PDF libs treat this as an afterthought

Quick example

doc := gpdf.New(gpdf.WithPageSize(gpdf.A4))
doc.Page(func(p *gpdf.PageBuilder) {
    p.Row(func(r *gpdf.RowBuilder) {
        r.Col(6, func(c *gpdf.ColBuilder) {
            c.Text("Invoice #1234", text.Bold())
        })
        r.Col(6, func(c *gpdf.ColBuilder) {
            c.Text("2026-03-22", text.AlignRight())
        })
    })
})
buf, _ := doc.Generate()
os.WriteFile("invoice.pdf", buf, 0644)
