remx··on Ask HN: What 'good' is being created on the internet these days?
Yeah Hypothesis is a bit nerdy. This is why Genius exists, and if rap/hip-hop is not your thing, Hypothesis can be used for any niche annotation.
remx··on Tor Browser 7.0a4 is released
Yep. Tor is just a great big eye for the NSA and GCHQ. For them it doesn't matter if scoundrels use it, as long as they can use it too.
remx··on Ask HN: How would you handle a large traffic spike (eg. being frontpage on HN)?
Make everything static. Unless you really need some sort of dynamic content. If you do need dynamic content, make sure to stress test it. There are tools out there to load test your website to see if it breaks.

Put it on Cloudflare. Cloudflare can absorb huge volumes of traffic with ease. Keep in mind there are other WAFs (Web Application Firewalls) you can check out.

Use as little third party widgets / bells and whistles as possible, and self host assets when you can. If these go down (which they will when your site is trending on Hackernews), then your site may not load correctly and leave your users frustrated. Remember the recent S3 failure? It broke thousands upon thousands of sites.

remx··on WannaCry – New Variants Detected
> So why now?

I think it's because it's cool to use the word "cyber" now in the news. It makes news outlets appear edgy and with it. Infact these cyber attacks are nothing new, and have been an ongoing problem for organizations like the NHS, the only difference being there is a remarkable uptick in the scale of the attack. The reason it stands out is because it's a cluster, instead of a slow, trickling problem for the NHS and other organizations.

> What's so special now?

The sophistication and worm capabilities. Were it not for the Shadowbrokers leak, small time malware authors had to use tired old strains of malware to spread. Now they can draw upon the vast arsenal of the Shadowbrokers leak and appear like state actors, which they are not.

If anything, the leaks were a blessing, because now we can mitigate against such attacks. NSA's mantra 'NOBUS' (No-one-but-us) does not apply here.

remx··on WannaCry – The largest ransom-ware infection in history
This is what I want to know[0] too.

To mitigate, you can disable SMB1.0 with the following command. Make sure to run as administrator:

    dism /online /norestart /disable-feature /featurename:SMB1Protocol

remx··on Accidentally Stopping a Global Cyber Attack
After the recent so called 'cyber attacks' of WannaCry, I was careful to update any Windows machine I have and install things like EMET and MalwareBytes on them. I switched to Linux years ago because I've heard nothing but bad news concerning Windows, but one thing struck me about the WannaCry infections: I heard the attackers used an exploit pulled from the recent ShadowBrokers leak, something related to 'SMB'. A few questions: Explain it to me like I'm five please

1.) What is SMB? And is it easy to remove from systems by simply uninstalling it (like I have done[0])?

2.) Does WannaCry just land on a machine through a simple point-and-click exploit? Do they just enter a vulnerable IP address and they can plant the exploit on the machine and run it?

3.) I am aware that it also gets onto machines by people randomly clicking on shady e-mail attachments, but I am very curious about how it simply lands on computers with very little or no user stupidity at all?

remx··on Ask HN: Globally Unique OS
Certain Linux live CDs usually have a read only filesystem and are useful for tasks where you don't want to leave a trace, and everything is flushed from RAM after use. Ubuntu, for example, allows a user to try out the O.S without installing and is a great way to 'trash the hotel room' and then shutdown leaving no trace of your actions. Any files you create, for example will be wiped, and the kernel is exactly the same when you restart the system cleanly. Just to be safe, I would recommend booting from read-only media like an actual read-only CD so nothing can persist.
remx··on Ask HN: How you scrape websites?
Greasemonkey[0] is fairly handy for scraping. You can even include remote resources like jQuery if you're targeting specific DOM elements in the page. For storing the data, you can just use LocalStorage (for example if you're paginating)

remx··on Accidentally Stopping a Global Cyber Attack
Thanks for the tip, and I will try this. As I said, .DOCX files work best in their native Win Office environment as I've had problems with them in open source solutions (formatting issues), whitespace injection ruining the layout, etc
remx··on Accidentally Stopping a Global Cyber Attack
To mitigate, I am running Debian as the host and jailing Windows 10 in a Virtual Machine, and have uninstalled SMB1.0 on the machine by going into > Programs and Features > Add or Remove Windows Components. I have also blocked port 445 (SMB) with ufw (On Debian)

    sudo ufw deny out to any port 445
Aswell as this I am not deferring updates in any way and dutifully patching. I've always hardened Windows in this way and I've never had issues with malware, and if I did, the impact would be minimal because I've compartmentalized my files in such a way that even the worst malware would only encrypt some of my files and not all of them.

I store all my critical files in an offline environment (sandbox) so the only files that are going to be encrypted are replaceable (non important) and disposable. For example, I wouldn't cry if my C.V got encrypted because a copy of it exists in about 50 locations either offline and online.

Unfortunately I need Windows because my colleagues like to send Windows-only .DOCX files which work best in MS Word, and I don't have a Google account, so I can't open them in Docs. This is a conscious decision to permaban Google from my life, but Windows is staying.

remx··on Welcome to 2030. I own nothing, have no privacy, and life has never been better
I doubt this could happen on any grand scale in a city. This does sound like the temporary autonomous zones you find in Burning Man, or the sustained exaltation you find at dinner parties and get-togethers. The key word here is sustained, because something always breaks exaltation. Someone makes a rude remark, or the wine goes to everyone's head and they make cynical remarks which dampen the mood of the dinner. Multiply this concept to cities and it's clear you're going to have bad apples ruining it for everyone. The bikes casually parked outside shops will be stolen even if they're freely given out to tourists to explore the city. The bum drinking cheap Olde English liquor will start begging for change.
remx··on πfs – A data-free filesystem

    As long as you know the index into p of your file and its length,
    its a simple task to extract the file using the Bailey–Borwein–Plouffe
    formula Similarly, you can use the formula to initially find the index of your file

    Now, we all know that it can take a while to find a long sequence of digits in p,
    so for practical reasons, we should break the files up into smaller chunks that
    can be more readily found.

    In this implementation, to maximise performance, we consider each individual
    byte of the file separately, and look it up in p.
I'm not entirely convinced my files would be present in those smaller chunks. You would need a copy of π (p) going way past the 5 trillion digit world record. Even then it's not guaranteed the bytes needed would be there.

&&

https://techcrunch.com/2016/07/25/security-as-a-service-star...

I have no experience with the Stackpath CDN itself, but I can only guess it's exactly like MaxCDN, which are apparently the cheapest and fastest. All these CDNs are more or less the same in terms of speed and availability though. Since it's such a competitive space, I don't really mind what CDN I use, as long as it's cheap compared to others and it has a decent amount of PoPs (Point of presence) scattered around the globe.

remx··on Ask HN: How do I view HN links with adblocker-blockers?
With uBlock Origin, you can select the HTML elements that are offending you, and remove them from the DOM It's called the 'elemental picker' and is a tiny picture of a pipette. You can use this to remove adblocker blockers. Some are more tricky to remove than others and can take some time.

If you don't want to use uBlock, you can always put yourself in a common pool of browser clients such as the TorBundle and blend in, thus improving your privacy. TorBundle doesn't block ADs.

remx··on Secure Computing for Journalists
> that laypeople have accepted and can work with

There is the caveat that it's hard to get things done in a timely manner on phones, or even tablets/phablets. If I need to crank out a lengthy blogpost, then I need a full desktop environment where I can do cross referencing, wikipedia lookups, file selection, photo editing, and all the other things that a desktop affords. I have tried writing a blogpost on an iPad and it took up my whole day when it should have taken 2-3 hours.

I know people who have developed super-fast methods for working on iOS but they are such a rare creature, and I'm not so sure their workflow is even teachable enough to be widely adopted by journalists or professional bloggers. From my experience they're relying on all sorts of hacks to get a blogpost out the door like using some perfectly curated mix of apps, and being able to pass files to and fro different apps with ease. Hardly the stuff of laypeople.

remx··on Secure Computing for Journalists
But if a journalist is going to use a secure desktop Operating System, he/she/they should investigate the current trio of recommendations which are as follows, and have different threat models baked into each:

Subgraph. Currently in Alpha version, so be careful using this. Still has to be vetted by the wider infosec community, but worth downloading and playing around with.

TailsOS. Very useful for journalists, but since it heavily relies on Tor it can be tricky dealing with mixed-anonymity workflows where sometimes you just need a Windows environment (preferably an airgapped Windows sandbox you can use to code / play around with files using Windows freeware).

Qubes. Heavily reliant on compartmentalization, and this can sometimes prove too cumbersome if you typically do one type of activity on the web like chat / email / hang out on slack. Typically for when you need to insulate different activities from each other and to avoid contaminating different contextual environments / tasks.
