White-box cryptographic implementations often use masking and shuffling as countermeasures against key extraction attacks. To counter these defenses, higher-order Differential Computation Analysis (HO-DCA) and its variants have been developed. These methods aim to breach these countermeasures without needing reverse engineering. However, these non-invasive attacks are expensive and can be thwarted by updating the masking and shuffling techniques. This paper introduces a simple binary injection attack, aptly named clear & return, designed to bypass advanced masking and shuffling defenses employed in white-box cryptography. The attack involves injecting a small amount of assembly code, which effectively disables run-time random sources. This loss of randomness exposes the unprotected lookup value within white-box implementations, making them vulnerable to simple statistical analysis. In experiments targeting open-source white-box cryptographic implementations, the attack strategy of hijacking entries in the Global Offset Table (GOT) or function calls shows effectiveness in circumventing run-time countermeasures.

Modern memory devices such as DRAM are prone to errors that occur because of unintended bit flips during their operation. Since memory errors severely impact in-memory key-value stores (KVSes), software mechanisms for hardening them against memory errors are being explored. However, it is hard to efficiently test the memory error handling code due to its characteristics: the code is event-driven, the handlers depend on the memory object, and in-memory KVSes manage various objects in huge memory space. This paper presents MemFI that supports runtime tests for the memory error handlers of in-memory KVSes. Our approach performs the software fault injection of memory errors at the memory object level to trigger the target handler while smoothly carrying out tests on the same running state. To show the effectiveness of MemFI, we integrate error handling mechanisms into a real-world in-memory KVS, memcached 1.6.9 and Redis 6.2.7, and check their behavior using the MemFI prototypes. The results show that the MemFI-based runtime test allows us to check the behavior of the error handling mechanisms. We also show its efficiency by comparing it to other fault injection approaches based on a trial model.

Most research on creativity describes it as a net positive: producing new products for the organization and satisfaction and positive affect for creative workers. However, a host of anecdotal and historical evidence suggests that creative work can have deleterious consequences for relationships. This raises the question: how does creativity at work impact relationships at home? Relying on work-family conflict and resource allocation theory as conceptual frameworks, we test a model of creative behaviors during the day at work and the extent to which employees spend time with their spouses at home in the evening, using 685 daily matched responses from 108 worker-spouse pairings. Our results reveal that variance-focused creative behaviors (problem identification, information searching, idea generation) lead to a decline in time spent with spouse at home. In contrast, selection-focused creative behaviors (idea validation) lead to an increase in time spent with spouse. Further, openness to experience moderates these relationships. Overall, the results raise questions about the possible relational costs of creative behaviors at work on life at home.

In order to acquire resources, new ventures need to be perceived as legitimate. For this to occur, a venture must meet the expectations of various audiences with differing norms, standards, and values as the venture evolves and grows. We investigate how the organizational identity of a technology venture must adapt to meet the expectations of critical resource providers at each stage of its organizational life cycle. In so doing, we provide a temporal perspective on the interactions between identity, organizational legitimacy, institutional environments, and entrepreneurial resource acquisition for technology ventures. The core assertion from this conceptual analysis is that entrepreneurial ventures confront multiple legitimacy thresholds as they evolve and grow. We identify and discuss three key insights related to entrepreneurs' efforts to cross those thresholds at different organizational life cycle stages: institutional pluralism, venture-identity embeddedness and legitimacy buffering.

Personal: I ran headfirst into a bit of a classic burnout two years ago. I’m still recovering from it. I’ve been trying to maintain a presence and not make this condition show too much, but I need to scale down the rest of my presence too for a while in order to reset and recharge.

I’ve been starting and re-starting writing this post way too many times now. I’ve decided to just post it as a stream of consciousness, readable or not as it may be, rather than my usual bar of having some sort of clear red thread with step-by-step logical coherence.

Two years ago, while moving from Stockholm to Berlin, I hit the infamous brick wall. I became incapable of most work that required any form of vehicular travel — I was literally limited to walking distance. Yes, it felt as ridiculous as it sounds, but it was just a matter of accepting the lay of the land and working with it. At the time, I was able to maintain some illusion of normality while starting to wind down and recover behind the scenes, thanks to being able to work remotely. I’ve since stopped working altogether — or so I thought, at least — and focusing on recharging.

When you drive a solar-powered rover too aggressively in Kerbal Space Program and the sun goes down, the batteries deplete quickly. You can’t start driving the rover again when the sun goes up from its state of depleted batteries, not even at its rated speed; you have to wait until the batteries have recharged, even if the circumstances (i.e. shining sun) should otherwise make you able to operate nominally. This is a little bit the state I’m in: I should nominally be fine, with most of the everyday load reduced significantly, but my batteries are still not recharging at the rate I had expected them to. (Yes, I’m impatient, which is admittedly part of the problem in the first place.)

So to all people who have written to me over this past time that I haven’t responded to: Please accept my apologies. It’s not out of malice or disinterest I haven’t responded, I’m simply getting done in a month what I used to get done in a day, and even that is a marked improvement. The “need to respond” queue is silly long by now, and includes conference invites and whatnot, that I would normally have responded to within minutes. It includes pings from near friends, that I had hoped to spend a lot more time with here in Berlin, as well as distant friends.

A close friend of mine pointed at a recent study about stress, a study looking at burnout symptoms in places with very good work-to-life balance, and the study concluded that the body doesn’t make a difference between obligations for work or obligations that are felt outside of work for any other reason than money. And she’s right: I’ve been feeling a pressure to shoot video, to code open-source projects, to participate in the community. I need to, bluntly speaking, drop all of these expectations for the foreseeable future. “Go off-grid” is a little too harsh, but I’ll need to turn off the expectation heartbeat on literally everything. I’ll do random things from time to time when I have the energy and desire for it, which unfortunately won’t be most of the time.

These recoveries basically take whatever damn time they please. I could have recharged batteries in six months, in a year, in ten years. I have honestly no idea and therefore I’m not setting any expectations, in either direction.

I’d like to say “I’ll be back”, but I don’t think the person on the other side of this recovery is going to be the same person I am today. I am sure I will still want to change the world for the better, somehow. I just can’t tell today how I’ll be wanting to change the world tomorrow. So even though I’ll very likely be back doing something, it’ll very likely not be the exact same things I’ve done up until this point.

7. Delivery time

The packed orders are picked up daily at 2.30 p.m. (Monday - Friday) by DHL / Deutsche Post. Thus, depending on the amount of shipping volume, all orders that we received by 2 p.m. and where the availability of all products in the shopping cart are "in stock (ready for dispatch)" on the same day handed over to our shipping service provider DHL / Deutsche Post. If products have the status "available (ready for dispatch in approx. 2-5 working days), we will order them from our suppliers and send them to you after we have received them. If you choose to pay in advance, we will wait until the payment has been received has been received in our bank account.

In general: ➜ delivery time = ready for dispatch + parcel delivery time

Ready for dispatch in ...

This is the time it takes to hand over the packaged goods to our shipping service provider.
This period of time can vary depending on the product or product option. This is always displayed in the detailed overview of each product:



Delivery time is always depending on three factors:

• product availability
• chosen payment option
• destination country

As a general rule:

➜delivery time = ready for dispatch + package run time


On this a tiny sample calculation:

With "on stock (ready for dispatch)" and with an average package run time of 1-2 working days (DHL inside Germany), a total package run time of 1-3 working days is resulting. (For delivery inside EU the total package run time increases by 1-3 weekdays, for delivery outside EU and Continental Europe by 3-8 working days).

Ready for dispatch in...

It´s about the time needed to deliver the prepared package to our shipping provider.

Depending on the product the term can be different. This is always shown in the detailed view of the product:




Following terms are possible:

• in stock (ready for dispatch)
• available (ready for dispatch ca. 2-5 work days)
• availability notification after order received
• curr. not available (delivery time upon request)

Please consider, that with an time designation of 2-5 working days the product has to be ordered at the distributer/producer. Delivery takes place after arrival in our stock.
